The Craving Brain: Neuroscience of Uncontrollable Urges
Summary
TLDRThe event discusses the enormous impact of addiction in the United States, emphasizing that over 25 million people suffer from addiction, costing around $600 billion annually. Healthcare professionals and scientists on the panel highlight that addiction is a chronic brain disease, where repeated drug use leads to long-lasting brain changes. Researchers are examining whether there are identifiable characteristics in the brains of addicts, even before substance abuse begins. Questions also arise about the possibility of reversing brain damage caused by addiction. The challenges are significant given the stigma surrounding addiction and the lack of integration into healthcare systems. Notably, children or adolescents developing addiction is particularly prevalent, given the plasticity of teenage brains. Earlier diagnoses could potentially lead to more effective interventions. Emerging treatment strategies are focusing on understanding genetic predispositions, developing addiction vaccines, and utilizing cognitive therapies. However, pharmaceutical companies are hesitant to invest in addiction treatment development due to financial unprofitability. The talk concludes by emphasizing the need for more scientific research to reduce the stigma and improve treatment outcomes for substance abuse disorders.

Deliver Public Health Net Gain Through Design - Summer Learning Programme 2023
- 00:00:10good evening I'm so glad to be with
- 00:00:13everybody tonight and so happy to see so
- 00:00:15many people turning out for this
- 00:00:17wonderful and interesting event as we
- 00:00:20all know I've done so much reporting on
- 00:00:21this and know firsthand a lot about this
- 00:00:24but the numbers are frightening and
- 00:00:26staggering when it comes to Addiction in
- 00:00:28this country there are more than 2 3
- 00:00:30and5 million addicts in the United
- 00:00:33States the costs are staggering the
- 00:00:36substance abuse costs 600 billion dollar
- 00:00:40every single year but The Cutting Edge
- 00:00:42scientists here on this stage tonight in
- 00:00:44just a few minutes are doing incredible
- 00:00:46work and will be joining me on the stage
- 00:00:49and to talk about that finding out about
- 00:00:51how the brains of drug addicts
- 00:00:54alcoholics smokers and perhaps even
- 00:00:57people who are obese may be different
- 00:01:00have special different characteristics
- 00:01:02we're also going to talk about whether
- 00:01:04or not you can tell an addict's Brain
- 00:01:06before they begin abusing a substance
- 00:01:10and whether or not the damage that
- 00:01:11addicts do to their brains can be
- 00:01:14reversed so they are learning that there
- 00:01:16is a physical change in brain also from
- 00:01:19adolescence to adulthood and this of
- 00:01:21course may explain why so many young
- 00:01:23people tend to get addicted in their
- 00:01:25teenage years there are also vaccines on
- 00:01:28the horizon if you can believe this that
- 00:01:30might be able to block the effect of
- 00:01:31addictive drugs and therefore May combat
- 00:01:34Addiction in this country there is of
- 00:01:36course so much urgency in their work and
- 00:01:39their study and it's not just because of
- 00:01:41the numbers of addicts and not just
- 00:01:44because the cost of addiction in this
- 00:01:46country every single year but most
- 00:01:48importantly the impact of addiction and
- 00:01:50addicts and what it has on their lives
- 00:01:52and the lives of their loved
- 00:01:54ones my name is Seth manukan I'm 42
- 00:01:57years old uh I attended Harvard
- 00:02:00University and I currently am the
- 00:02:02associate director of mit's graduate
- 00:02:04program in science writing I've written
- 00:02:07three books my most recent book the
- 00:02:09Panic virus um about vaccines and autism
- 00:02:13uh won the National Association of
- 00:02:15science writers science and Society book
- 00:02:18award I'm very luckily and happily
- 00:02:21married with two children and for the
- 00:02:24better part of 10 years I was a drug
- 00:02:28addict I started experiencing fairly
- 00:02:32severe anxiety around when I was 7 years
- 00:02:36old I became obsessed with my walking
- 00:02:39and obsessed with my breathing and
- 00:02:41eventually by the time I was eight or
- 00:02:43nine uh I began to have a lot of trouble
- 00:02:47sleeping I never sought out drugs
- 00:02:49consciously because of anxiety uh I
- 00:02:53thought of myself as someone who was um
- 00:02:56countercultural to the extent that a
- 00:02:59white middle class child living in
- 00:03:01Newton Massachusetts could be
- 00:03:04countercultural but was also aware from
- 00:03:07very early on that I was not using drugs
- 00:03:12in a way that was conducive to having a
- 00:03:14good time I I was sharing needles um
- 00:03:20with uh people who I knew were not safe
- 00:03:25I went through a couple of phases of
- 00:03:28pretty severe
- 00:03:30crack use on one particular occasion I
- 00:03:33became convinced that I had somehow
- 00:03:35spilled some crack uh on the floor of
- 00:03:39the kitchen of the rental apartment
- 00:03:41where I was living and so um I ended up
- 00:03:43essentially like digging up lenium uh to
- 00:03:47see if there was like you know crack
- 00:03:50residue on it my family had not
- 00:03:55completely cut off contact with me but
- 00:03:57were very close to that they had changed
- 00:03:59locks on the house they started to check
- 00:04:02in with each other on a daily basis to
- 00:04:05see if something had happened to me
- 00:04:08there were so many points in that period
- 00:04:13of my life when I was addicted where you
- 00:04:16know
- 00:04:16literally one tick of the clock one
- 00:04:21second difference um and I wouldn't be
- 00:04:26here when Philip SE hoffen died
- 00:04:30it did really affect
- 00:04:31me he had been sober for over 20 years
- 00:04:37and uh you know then he picked up and
- 00:04:41now he's dead um and just the speed with
- 00:04:44which that
- 00:04:45happened it made
- 00:04:48me realize the vigilance that um I need
- 00:04:55to have
- 00:04:57to um never forget the fact that I spent
- 00:05:03the better part of a decade as a drug
- 00:05:12addict I feel very lucky that I made it
- 00:05:15through there were a lot of people that
- 00:05:19I used with that
- 00:05:24didn't biggest misconception about
- 00:05:26addiction is the sense that it's a
- 00:05:28willpower issue
- 00:05:32we have come a long way towards
- 00:05:34recognizing that addiction is a disease
- 00:05:37but we still have a long way to
- 00:05:39go we'll be talking a lot more about
- 00:05:42that willpower um debate because as Seth
- 00:05:45just pointed out even though for decades
- 00:05:47the AMA has classified addiction as
- 00:05:50alcoholism for example as a disease so
- 00:05:53many people in society now still view
- 00:05:55this as you aren't strong enough you
- 00:05:57aren't committed enough you you just
- 00:05:59don't have enough willpower to stop and
- 00:06:03the science and the scientists you're
- 00:06:04about to meet will tell you that in many
- 00:06:07cases it is not about willpower at all
- 00:06:10it is about something much more
- 00:06:12fundamentally scientific so let's meet
- 00:06:15our
- 00:06:16panel as a research psychiatrist and
- 00:06:18scientist our first participant
- 00:06:20pioneered the use of brain Imaging to
- 00:06:22investigate the toxic effects and
- 00:06:25addictive properties of abusable drugs
- 00:06:28her Studies have documented changes in
- 00:06:30the dopamine system affecting among
- 00:06:32others the functions of frontal brain
- 00:06:34regions involved with motivation drive
- 00:06:37and
- 00:06:38pleasure as the Director of the National
- 00:06:41Institute on drug abuse for the past 11
- 00:06:43years she perhaps more than any
- 00:06:45individual is guiding us on how we
- 00:06:47research drug abuse and addiction please
- 00:06:50welcome Dr Nora
- 00:06:52volov hello
- 00:07:01our next participant is the chair of the
- 00:07:03Neuroscience department and director of
- 00:07:05the Freedman brain Institute at Mount Si
- 00:07:07University Medical Center his research
- 00:07:10aims to better understand the molecular
- 00:07:12mechanisms of addiction he is a leader
- 00:07:14in the study of how drug addiction
- 00:07:16impacts gene expression please welcome
- 00:07:18Dr Eric
- 00:07:25nestler our next participant is the Eli
- 00:07:28Callaway Jr chaired professor at the
- 00:07:30scripts Research Institute he developed
- 00:07:33a vaccine that blocked the effects of
- 00:07:35heroin addiction and hopes to extend the
- 00:07:37research to Other Drugs such as nicotine
- 00:07:40and alcohol as well as other drugs
- 00:07:42please welcome Dr Kim
- 00:07:48jand and our final participant is a
- 00:07:51psychiatrist and neuroscientist at
- 00:07:53Columbia University and authored
- 00:07:55research on nicotine being a gateway
- 00:07:58drug to cocaine
- 00:08:00with Eric and Denise candell he also is
- 00:08:03working currently on how the Adolescent
- 00:08:05brain looks different than the adult
- 00:08:07brain and how that can make them more
- 00:08:09susceptible to addiction the adolescence
- 00:08:11please welcome Dr Amir
- 00:08:18LaVine and before we start I just want
- 00:08:21to encourage you uh feel free to jump in
- 00:08:23uh if you somebody says something that's
- 00:08:25interesting that you can elaborate on um
- 00:08:28this isn't a sign
- 00:08:30answers only but I do want to start with
- 00:08:32you Dr volov um before we start to
- 00:08:35examine how the addicted brain actually
- 00:08:37looks can you just give us a broad sense
- 00:08:39of the state of addiction the play of
- 00:08:41addiction the politics of addiction in
- 00:08:43this country that's a complex question I
- 00:08:46can say what we know from science we've
- 00:08:49come to recognize that repeated drug use
- 00:08:52uh changes the brain in longlasting ways
- 00:08:55and that has led to the concept not just
- 00:08:57that addiction is a disease of the brain
- 00:08:59but that it's is a chronic disease which
- 00:09:01is very relevant for treatment because
- 00:09:03it means that you require continued
- 00:09:05treatment and in that respect is not
- 00:09:07different from cancer which we for most
- 00:09:10of the cancers we cannot cure but we can
- 00:09:12treat and so is the situation with drug
- 00:09:15addiction unfortunately even though the
- 00:09:18science has shown that the it's a
- 00:09:21disease of the brain it has been very
- 00:09:23difficult to incorporate into the
- 00:09:25healthcare system and as a result of
- 00:09:28that um many many cases of drug
- 00:09:31addiction are never recognized or
- 00:09:33prevented or treated and so when you're
- 00:09:35speaking to me about the question on the
- 00:09:37politics I think that there's a lot to
- 00:09:39do yet in order to be able to bring
- 00:09:41addiction into the healthc care system
- 00:09:44and also to change the attitudes because
- 00:09:47uh addiction is still highly highly
- 00:09:48stigmatized and as a result of that
- 00:09:51people that are addicted themselves are
- 00:09:53afraid to ask for help and the families
- 00:09:56don't speak about it because they don't
- 00:09:57want to be stigmatized
- 00:09:59and now that Healthcare reform is coming
- 00:10:02up for the first time we're going to
- 00:10:04have the opportunity of getting
- 00:10:06Insurance to people that are addicted to
- 00:10:07drugs but otherwise is basically the
- 00:10:10resources have not been there to help
- 00:10:12address the problem you were talking
- 00:10:14about the long-term damage that drug
- 00:10:16abuse does to the brain you just heard
- 00:10:17Seth manukan in that video talk about
- 00:10:19Philip Seymour Hoffman 23 years sober um
- 00:10:24reportedly picked up a drink at a rap
- 00:10:26party for a movie one cocktail is what
- 00:10:28led him down that slippery slope back to
- 00:10:31heroin and that's how he died yeah know
- 00:10:34and it's a very unfortunate but really
- 00:10:36do epitomize uh that's uh knowledge that
- 00:10:39we have that the changes are very
- 00:10:41longlasting and persist months or years
- 00:10:45after the person has stopped taking the
- 00:10:46drug which is why I come back to the
- 00:10:49sense we need to recognize that it's a
- 00:10:51chronic chronic disease and that people
- 00:10:53that have suffered from it have to be
- 00:10:56cautious and sustain some level of
- 00:10:58treatment in in order to prevent them
- 00:11:00from relapse what and and we see I mean
- 00:11:02that is a very tragic story but
- 00:11:04unfortunately it's not as unique and you
- 00:11:07see it people that have been able to
- 00:11:09stay drug free for 10 years then
- 00:11:11something stressful happens and they
- 00:11:13relapse and they escalate immediately to
- 00:11:15the same levels that they were taking
- 00:11:18before 10 years prior so it this is what
- 00:11:21characterizes the process of uh drug
- 00:11:23addiction there are essentially
- 00:11:25permanent physical changes in the brain
- 00:11:28at several levels M that could be seen
- 00:11:30as molecular cellular scars of the
- 00:11:33addiction and these can last a lifetime
- 00:11:35so that when a person like Philip seor
- 00:11:37Hoffman comes across a drink for the
- 00:11:39first time or heroin for the first time
- 00:11:41the relapse can be very rapid and severe
- 00:11:44but I'm I'm just curious and this is to
- 00:11:46all of you the damage that you do to
- 00:11:49your brain by chronic drug abuse or by
- 00:11:52alcoholism is any of it reversible we
- 00:11:55always hear that you know some drugs
- 00:11:58permanently Dam for example you know
- 00:12:00crystal meth a large a completely
- 00:12:02synthetic drub does that do irreversible
- 00:12:04damage are you is that done there's
- 00:12:06nothing you can do ever to to fix your
- 00:12:08brain
- 00:12:09again I'm smiling because it's obviously
- 00:12:11something that I've been in very much
- 00:12:13interested on looking at and Depends
- 00:12:16when you have would have asked me that
- 00:12:17question but there's been tremendous
- 00:12:19tremendous advances in our understanding
- 00:12:21about how the brain actually repairs
- 00:12:24itself a lot of it driven by work done
- 00:12:27on the recovery of the brain when
- 00:12:29someone suffers a stroke and now the
- 00:12:32rehabilit tra brain injury exactly the
- 00:12:34rehabilitation process allows for them
- 00:12:36to recover significantly function and
- 00:12:39we're making advances to try to
- 00:12:41accelerate that process so I would say
- 00:12:44that there as of now there is
- 00:12:47significant recovery but it's also
- 00:12:49variable some some people recover faster
- 00:12:51than others depends on your age depends
- 00:12:53how many drugs that you have had but it
- 00:12:55also depends on your genetics but I also
- 00:12:58see it that very optimistic and I'm not
- 00:13:00one of those fluffy optimism optimists
- 00:13:03but actually based on what we know of
- 00:13:06the science where it's going that in the
- 00:13:08future we will be able to accelerate
- 00:13:10that process of recovery but that's my
- 00:13:13perspective I mean my colleagues here
- 00:13:15agre that that it is possible can you
- 00:13:18elaborate Dr volov gives me a lot of
- 00:13:21grant money so I can't disagree with her
- 00:13:24no no no Eric come on U no I agree I
- 00:13:27think the brain has a norm enormous
- 00:13:29reparative processes and a lot of the
- 00:13:32things that drugs do to damage the brain
- 00:13:34are probably reversible probably the
- 00:13:37aspect that persist what amount of time
- 00:13:40well I think it varies from person to
- 00:13:42person and type of change to type of
- 00:13:44change but uh one of the things that
- 00:13:47lasts the longest is are the memories
- 00:13:51associated with drug use and the
- 00:13:54conditioning the learning that occurs uh
- 00:13:57as Nora mentioned a person could
- 00:13:59come across a stressful experience be
- 00:14:01absent in for years a bit of stress
- 00:14:04basically dark periods that every person
- 00:14:06has different points in their lives come
- 00:14:09about and those memories of how to deal
- 00:14:11with the stress come up as the easiest
- 00:14:15thing to do is to go back to drug to
- 00:14:17make you feel better not just that it's
- 00:14:19not just that that's your sort of go-to
- 00:14:21knee-jerk
- 00:14:22reaction I've also heard that the actual
- 00:14:25memories that you form while abusing
- 00:14:28alcohol abusing drugs are more Vivid
- 00:14:31more powerful in a sense is that the
- 00:14:35case yes think yeah I think you have to
- 00:14:37look at the brain it's it's Dynamic it's
- 00:14:39not static it's constantly being
- 00:14:41remodeled whether you're taking a drug
- 00:14:43or not taking a drug and um you know
- 00:14:46that's the difficulty of treating these
- 00:14:48disease caused by this is because
- 00:14:51there's so many processes that if you
- 00:14:53block maybe one receptor it can go down
- 00:14:55another pathway but you know one of the
- 00:14:57things that is to your question question
- 00:14:59of memory of why it's exactly on On
- 00:15:01Target we we remember things that are
- 00:15:04emotionally rid right so when the Twin
- 00:15:07Towers came down each one of us
- 00:15:08remembers what they were doing and this
- 00:15:10is because it was horrific it was
- 00:15:13unexpected and when events that are
- 00:15:15unexpected and Salient occure you
- 00:15:18liberate dopamine and dopamine then
- 00:15:20stimulates and high concentrations a
- 00:15:23specific type of proteins that results
- 00:15:25in this immediate um conditioning and
- 00:15:29conditioning is a memory that will label
- 00:15:31you when you are exposed to the same
- 00:15:33situation not just to remember
- 00:15:35conceptually but to feel it and drugs by
- 00:15:39their pure nature drugs increase
- 00:15:41dopamine so when you take a drug You Are
- 00:15:44by default activating this memory
- 00:15:46process that that Eric was speaking
- 00:15:48about which we call conditioning and
- 00:15:50this conditioning will lead you to
- 00:15:53desire that drug the next time you're in
- 00:15:55the same environment so you become
- 00:15:57conditioned and those are the memories
- 00:15:59that actually stay with you and will
- 00:16:02drive the behavior even years after you
- 00:16:04have not seen the drug is that why I've
- 00:16:06heard addicts talk about the fact um in
- 00:16:09particular one heroin addict I knew who
- 00:16:11would she told me about her using dreams
- 00:16:14like you you hear addicts in recovery
- 00:16:16talking about that a lot the dreams that
- 00:16:18they have of either drinking or shooting
- 00:16:21up or doing whatever it was that they
- 00:16:23did that led them to get into trouble
- 00:16:25that's actually very common and um I'm
- 00:16:27also I'm I'm a clinician as well as a
- 00:16:29scientist and I actually wanted to say
- 00:16:31that there is a lot of hope I have I
- 00:16:32mean just from my own clinical practice
- 00:16:34and experience I've known um I known
- 00:16:37quite a few people who were able to um
- 00:16:40become sober even from crystal meth and
- 00:16:42other drugs and actually really resume a
- 00:16:44very productive life um but they do talk
- 00:16:46about uh drug dreams and they have
- 00:16:48different attitudes to cope with those
- 00:16:50drug dreams some people say okay they
- 00:16:51wake up in the morning and they just
- 00:16:53laugh at it and they say okay I had a
- 00:16:54drug dream and I can move on or even
- 00:16:57like okay I got a chance to try it out
- 00:16:59without really relapsing so they have a
- 00:17:02positive attitude and but some people
- 00:17:03are really traumatized by it and it's
- 00:17:05really hard for them it's just I've
- 00:17:07heard that they're Vivid that way and I
- 00:17:08wondered if that was related to the fact
- 00:17:10that the memory itself the imprint on
- 00:17:12the brain has been so all right well
- 00:17:14let's we've got some slides let's start
- 00:17:16U with one of the slides that you have
- 00:17:18of a brain addicted to uh cocaine in
- 00:17:20this case what what are we looking at
- 00:17:23well what you're looking at there is
- 00:17:24actually um we're measuring images um
- 00:17:28that reflect the concentration of a
- 00:17:30protein that we call dopamine D2
- 00:17:33receptor and it's a protein that is very
- 00:17:36important because because it regulates
- 00:17:38the function of the cortical processes
- 00:17:41it regulates it actually allows us to
- 00:17:43exert control you see the control
- 00:17:46subjects and in the center of the brain
- 00:17:47you see high red areas because that's
- 00:17:50where you have very high concentration
- 00:17:51of these D2 receptors then you see a
- 00:17:54metamphetamine abuser with much lower uh
- 00:17:57coloring red on the center of the brain
- 00:17:59because the receptors are down the
- 00:18:01dopamine D2 receptor and then you see a
- 00:18:04control subject to the I don't know I
- 00:18:07actually have to look back to your right
- 00:18:09and you see that color and you also see
- 00:18:11that in the alcoholic is down and this
- 00:18:13is a very typical uh change that we
- 00:18:15observe across a wide variety of
- 00:18:17addictions people that are addicted to
- 00:18:20drugs have a reduction in the expression
- 00:18:22of these proteins that dopamine D2
- 00:18:24receptors and these decreases in the
- 00:18:26expression of dopamin D2 receptors in
- 00:18:29humans and in animal models and Eric has
- 00:18:32done a lot of work here to actually are
- 00:18:34associated with impulsive behaviors and
- 00:18:37a propensity to engage in compulsive
- 00:18:39behaviors when you are exposed to um
- 00:18:42rewarding
- 00:18:43stimuli and and this is because again
- 00:18:46this these areas in the center of the
- 00:18:48brain which we call the striatum and in
- 00:18:50these areas that D2 receptors allows us
- 00:18:53to regulate the frontal cortex the
- 00:18:55frontal areas of the brain here which
- 00:18:57are crucial for our ability to exert
- 00:19:00self-control whether it is uh
- 00:19:02controlling our emotions or our desires
- 00:19:05but but proper signaling through these
- 00:19:07D2 receptors is necessary for the
- 00:19:09function of our prefrontal cores so
- 00:19:13basically what we're looking and I'm
- 00:19:15just curious were these people did these
- 00:19:19alcoholic brains and methamphetamine
- 00:19:20abuser brains look this way before they
- 00:19:23began abusing methamphetamines and
- 00:19:26alcohol well unfortunately when when you
- 00:19:28are doing these clinical studies it's
- 00:19:30very difficult to have measures before
- 00:19:32they take out uh drugs and so in this
- 00:19:35case we do not know if these decreases
- 00:19:37are due to the use of drugs or whether
- 00:19:39they were like that and that make them
- 00:19:41vulnerable but we can take these
- 00:19:43findings and then bring them into an
- 00:19:45animal model in the laboratory and ass
- 00:19:48say for example and this has been done
- 00:19:50both in rodents and in nonhuman primates
- 00:19:52where you measure that D2 receptors
- 00:19:55before and after longterm exposure to
- 00:19:58the draw
- 00:19:59and stories have shown that indeed when
- 00:20:01you give in non-human primates repeated
- 00:20:05administration of cocaine you bring down
- 00:20:07the levels of dopamine D2 receptors in
- 00:20:10the brain so we do know that repeated
- 00:20:12use of drugs will bring them down but as
- 00:20:15for this particular subjects we cannot
- 00:20:18be ever certain whether this is the drug
- 00:20:21it's it's very likely that that drugs
- 00:20:23are contributing to the reductions that
- 00:20:25we can say and and if these two um
- 00:20:29brains this alcoholic and this drug
- 00:20:32addict were able to remain sober would
- 00:20:35their brains go back to looking like the
- 00:20:36control subjects we've uh we've tried to
- 00:20:39look at that and in the metamphetamine
- 00:20:41abusers where we have been more
- 00:20:44successful we have seen actually some
- 00:20:47recovery in some individuals but not in
- 00:20:50others so we see a tremendous
- 00:20:52variability on the rate of recovery of
- 00:20:55the brain when a person stops taking the
- 00:20:57taking the drug and and uh we are not
- 00:21:00certain exactly what's determining the
- 00:21:02ability to recover after abstinence one
- 00:21:05of the factors that's likely to play a
- 00:21:06very important role is your age the
- 00:21:08younger you are the the more resilient
- 00:21:11your brain is and the faster it recovers
- 00:21:13but also the characteristics of the
- 00:21:15drugs that you're taking uh we see the
- 00:21:17worst outcomes when we have people that
- 00:21:20take multiple drugs of abuse that's
- 00:21:22appears to be particularly harmful for
- 00:21:24example combination of alcohol and
- 00:21:25cocaine methamphetamine and alcohol
- 00:21:28those are very harmful and it is very
- 00:21:30likely that obviously genetics play a
- 00:21:32role we're going to get to genetics in a
- 00:21:34in a moment but you also had one more sh
- 00:21:36slide you wanted to show us uh uh
- 00:21:38because you've studied obesity and and
- 00:21:40think that actually addiction to food
- 00:21:42may be very similar to I mean a lot of
- 00:21:45people don't view that we have a hard
- 00:21:47enough time getting people to accept the
- 00:21:48fact that addiction to alcohol or
- 00:21:50addiction to methampetamine is a
- 00:21:52sickness addiction to food is something
- 00:21:54else well it's interesting because the
- 00:21:56reason why we started to work with
- 00:21:58obesity was we were showing
- 00:22:00systematically these reductions in
- 00:22:02dopamine D2 receptor acoss a wide
- 00:22:04variety of types of addiction and there
- 00:22:07was a there's a certain similarity in
- 00:22:09the phenotypic expression that you see
- 00:22:12in in obesity of compulsive food
- 00:22:14consumption despite the fact that people
- 00:22:17don't want to eat anymore and despite
- 00:22:19its very adverse consequences so at that
- 00:22:22time I was very interested to see if one
- 00:22:24would observe the same changes in D2
- 00:22:27receptors uh in a in a presentation that
- 00:22:30behavioral is very similar but did not
- 00:22:33require the administration of a a
- 00:22:35chemical artificial substance and that's
- 00:22:38how we ended up studying obesity and
- 00:22:40long and behold we identify these
- 00:22:43changes that you see there that in obese
- 00:22:45individuals by the way these are
- 00:22:47morbidly obese individuals uh they did
- 00:22:50have also like we had seening people
- 00:22:52that were addicted to drugs a reduction
- 00:22:55in the levels of dopamine D2 receptors
- 00:22:57in their brains okay uh let's turn uh
- 00:23:01very quickly to Dr nestler um I wanted
- 00:23:04to pick up this whole dopamine issue
- 00:23:06with you because you've gone deeper into
- 00:23:07the smaller amount of dopamine that has
- 00:23:09just been released in adx MH let's watch
- 00:23:12the video that we prepared uh it will
- 00:23:15show uh a um cartoon of a brain and then
- 00:23:19focusing in uh on on a particular part
- 00:23:22of the brain which makes uh has neurons
- 00:23:24that make the chemical transmitter
- 00:23:26dopamine uh while we're waiting for the
- 00:23:28video I could just give you some
- 00:23:29background a human brain has about 100
- 00:23:31billion nerve cells so that's a big
- 00:23:34number each nerve cell communicates with
- 00:23:37thousands of other nerve cells at points
- 00:23:39of contact called synapses that means a
- 00:23:42single human brain has about 100
- 00:23:44trillion
- 00:23:45synapses um and uh for what it's worth
- 00:23:49that's a bigger number 100 trillion than
- 00:23:51the total number of stars that Einstein
- 00:23:54estimated was in the entire universe so
- 00:23:56in the single human brain so so now
- 00:23:58we're focusing in on the center part of
- 00:24:00the brain where there are chemical
- 00:24:02transmitters released from the end of
- 00:24:04one nerve cell those little uh yellow
- 00:24:07spheres would be another one transmitter
- 00:24:10that's another transmitter this is
- 00:24:11supposed to be a dopamine nerve cell and
- 00:24:14in the course of chronic Drug
- 00:24:16Administration what we and other groups
- 00:24:18have seen that certain drugs of abuse
- 00:24:20actually causes a shrinkage of these VTA
- 00:24:23dopamine nerve cells so a physical loss
- 00:24:27in the robustness of the cells and a
- 00:24:29loss of dopamine release and that
- 00:24:32coincides with what Norah had and
- 00:24:34colleagues have shown that there is
- 00:24:36fewer receptors that recognize the
- 00:24:39dopamine so in a an addict's brain
- 00:24:42there's an impaired dopamine nerve cell
- 00:24:45and an impaired ability to detect the
- 00:24:48dopamine leading to a dramatic reduction
- 00:24:51in the ability to experience reward so
- 00:24:55throughout life we walk around we eat a
- 00:24:57good meal
- 00:24:59uh someone uh tells us they love us we
- 00:25:02see a friend have sex whatever a reward
- 00:25:04might be uh that releases dopamine and
- 00:25:07keeps us going an addict does not have
- 00:25:10in the extreme does not have those same
- 00:25:13experiences because their dopamine
- 00:25:15pathway is impaired so they so natural
- 00:25:18reward is impaired and because they're
- 00:25:21feeling short circuited exactly they go
- 00:25:24out and abuse something to try get that
- 00:25:26reward the easiest way to feel normal
- 00:25:28again is by taking the
- 00:25:30drug so by taking the drug does it does
- 00:25:34it elevate More release of dopamine does
- 00:25:37it bring them back up to where probably
- 00:25:40never back to where they would be with a
- 00:25:43person who has a normally functioning
- 00:25:45dopamine system getting a a strong
- 00:25:48natural
- 00:25:50reward and is is do you have other
- 00:25:52animation too or is that the only one
- 00:25:54you have I have one more but I don't
- 00:25:55need to show it now no let's show it
- 00:25:57okay let's show one more this one
- 00:25:59relates to this these videos look like
- 00:26:02space aliens or something this is
- 00:26:05supposed to be the a branch of a nerve
- 00:26:07cell that those mushrooms are really
- 00:26:10what are called spines that are
- 00:26:13protruding from the uh dendrite what's
- 00:26:16called a dendrite to receive incoming uh
- 00:26:19information let's run the video one more
- 00:26:21time please and what happens and I think
- 00:26:24that this type of growth of these spies
- 00:26:28growth of new synapses is what's
- 00:26:31mediating now you'll watch and you'll
- 00:26:32see drug exposure gradually
- 00:26:35progressively over time leading to an
- 00:26:37increase in these uh Detectors of
- 00:26:40synaptic transmission this is probably
- 00:26:43among the mechanisms that are mediating
- 00:26:45these lifelong
- 00:26:47memories I'm sorry you lost there sorry
- 00:26:49about that so the beginning do everybody
- 00:26:51have a PhD in
- 00:26:53Neuroscience I left mine at home um the
- 00:26:57beginning was is a normal person's brain
- 00:27:00and then after chronic drug addiction
- 00:27:02you grow more of these things
- 00:27:04connections yes and how does more of
- 00:27:06those connections why is that a bad
- 00:27:09thing it probably depends on where in
- 00:27:11the brain this is occurring but in the
- 00:27:13part of the brain that we're talking
- 00:27:14about these increased connections
- 00:27:16represent uh very powerful memories that
- 00:27:20would per for example draw a connection
- 00:27:22between feeling stressed taking drug as
- 00:27:25a way to relieve the stress got it and
- 00:27:27that's the way we are beginning to
- 00:27:30understand how the brain mediates those
- 00:27:32phenomena did you want to add something
- 00:27:34no I really like this finding because
- 00:27:36that she relates to some of my findings
- 00:27:38later on so you really liked your cool
- 00:27:41video well let's talk about genetics
- 00:27:43because you mentioned that a moment ago
- 00:27:45and I'm curious um first of all one
- 00:27:50quick
- 00:27:51question can you look at a brain of
- 00:27:54somebody and tell if they're going to
- 00:27:55become an addict in other words right
- 00:27:58now not right now that would be a great
- 00:28:01goal so is there a gene we we keep
- 00:28:05hearing that there's a genetic link for
- 00:28:07addiction but I mean that would mean you
- 00:28:10were born an
- 00:28:11addict is is I'm curious I'd like to
- 00:28:15hear all of you Weighing on that it's
- 00:28:16different from eye color or height which
- 00:28:19you're born with brown eyes you'll have
- 00:28:20brown eyes for Life uh the genetics that
- 00:28:23underly common chronic disease whether
- 00:28:27it's psychiatric disease or diabetes and
- 00:28:29Asthma is much more complex and what
- 00:28:32we're talking about are genes that
- 00:28:34confer a risk for an illness not a
- 00:28:37deterministic uh shity that they will
- 00:28:40get that illness so for example the
- 00:28:41genetic risk for addictions is about 50%
- 00:28:44that's really heritable that's more
- 00:28:46heritable than high cholesterol high
- 00:28:48blood pressure what do you mean by 50%
- 00:28:5150 half of the risk for addiction is
- 00:28:53genetic really yes and what is it what
- 00:28:56what is it for cancer for for many
- 00:28:59cancers it's even less than 50% so
- 00:29:02addiction is actually pretty genetic the
- 00:29:05challenge is is that unlike something uh
- 00:29:09for example Huntington disease which is
- 00:29:12caused by an abnormality in a single
- 00:29:13Gene and if you have that abnormal copy
- 00:29:15of the gene you will get Huntington's
- 00:29:17disease with 100% Assurance that's not
- 00:29:20the case in addiction because only half
- 00:29:23of the risk is genetic and the rest
- 00:29:25depends on all sorts of other things and
- 00:29:27we can't at this point look at that Gene
- 00:29:30I mean it's not like the breast cancer I
- 00:29:32mean we haven't it's been very hard to
- 00:29:33find them I mean this is one of the
- 00:29:35major focuses of naida but you know one
- 00:29:38of the things in terms of what Eric was
- 00:29:40saying we are coming to realize that
- 00:29:42it's not like with Huntington where you
- 00:29:44identify a gene and you know you're
- 00:29:45going to develop the disease but what
- 00:29:47we're understanding is that these genes
- 00:29:50are influencing the way that the brain
- 00:29:52develops and ultimately functions so the
- 00:29:54risk that they are imposing has to do
- 00:29:56with the fact that your brain will be
- 00:29:58responding to an environmental insult in
- 00:30:01a different way one of the one most
- 00:30:03investigated is for example a gene that
- 00:30:05gives you that modifies the way that the
- 00:30:08amigdala which is a lyic area responds
- 00:30:11to stress so if you have this Gene that
- 00:30:14is a high-risk Gene it will make you
- 00:30:16much more vulnerable to depression but
- 00:30:19only if you are in a stressful
- 00:30:21environment the same thing for example
- 00:30:23since now it's so much in the news the
- 00:30:25association between certain people
- 00:30:27taking marijuana and then developing
- 00:30:29schizophrenia what now is coming to
- 00:30:31realize is that if you have a certain
- 00:30:33Gene which is has a a risal yeld that
- 00:30:36makes you more vulnerable to
- 00:30:38schizophrenia if you smoke marijuana
- 00:30:41then can accelerate the process so we're
- 00:30:44understanding genes as influencing the
- 00:30:46risk and this is not just for drug
- 00:30:47addiction for all of the mental diseases
- 00:30:50U for basically most of them but even
- 00:30:52for many of the medical diseases such as
- 00:30:55diabetes or obesity you may have a gene
- 00:30:57that creates a vulnerability but if you
- 00:30:59don't expose to the environmental insult
- 00:31:03it will never happen which is from the
- 00:31:05policy perspective and from the health
- 00:31:07care perspective very important because
- 00:31:09it doesn't mean you are predestined to
- 00:31:12develop the disease but you can actually
- 00:31:15do
- 00:31:15interventions that can um help that
- 00:31:19individual that can protect that person
- 00:31:22from the development of these conditions
- 00:31:24so when you hear people in recovery say
- 00:31:25I was born an addict
- 00:31:28you you don't think that's possible I
- 00:31:30mean other things in life have to
- 00:31:32conspire I mean this is what a lot of
- 00:31:34what you do right I think they basically
- 00:31:36they were born with their propensity um
- 00:31:38and then things happened that actually
- 00:31:41drove them to become an addict but
- 00:31:42certainly if there's a family history
- 00:31:43there's a much much greater risk or
- 00:31:46perhaps born with you know we just had
- 00:31:47we don't have that slide up anymore a
- 00:31:49brain that doesn't uh as
- 00:31:53efficiently uh ex whatever it is
- 00:31:56exchange dop
- 00:31:59experience dopamine or perhaps even a
- 00:32:01tendency to really try to do things in
- 00:32:04the most to go all the way as much as
- 00:32:08they can so it can be good if you're in
- 00:32:09a certain job but it it may not be good
- 00:32:12if you're a child and you're taking one
- 00:32:13candy and then you can't stop and you
- 00:32:15want another and another and another so
- 00:32:16it's just a propensity and it depends on
- 00:32:18what you're going to do with it and what
- 00:32:20about I was so interested to hear in
- 00:32:22this video this with Seth manukan
- 00:32:24talking about always feeling anxious as
- 00:32:26a child so many addicts um will tell you
- 00:32:30you know of that feeling always a
- 00:32:32feeling different other not fitting in
- 00:32:35but also you're hearing more and more
- 00:32:37lately about this this anxiety
- 00:32:40component right I think that there's
- 00:32:43there's a lot of what we call
- 00:32:44comorbidity with the drug addiction so
- 00:32:47people who suffer from addiction often
- 00:32:49time a lot of the time also suffer from
- 00:32:50other psychiatric disorders and
- 00:32:52oftentimes as I'm going to talk about
- 00:32:54the importance of adolescence it starts
- 00:32:55early on and anxiety is a major it's one
- 00:32:58of the most common uh disorders in
- 00:33:00adolescence and in children and uh and
- 00:33:03if they can find something that will
- 00:33:04help them then they will use it sure if
- 00:33:07you spent your entire childhood fighting
- 00:33:09panic attacks every day or every week
- 00:33:11and and all of a sudden somebody says
- 00:33:13you know have a glass of wine or have a
- 00:33:15beer and you feel a lot more comfortable
- 00:33:17in the world you could understand why
- 00:33:19somebody might begin to abuse that yeah
- 00:33:21all right um let's talk also there
- 00:33:24there's one other um term that you've
- 00:33:26brought out the gene expression did did
- 00:33:27you talk about that already I don't
- 00:33:29think so but I could talk about it now
- 00:33:31or why don't we move on you want no go
- 00:33:33ahead and talk about it now the
- 00:33:36um right
- 00:33:38now a lot of these changes that we're
- 00:33:40talking about are mediated through
- 00:33:43changes in gene
- 00:33:45expression and it's a hard concept to
- 00:33:48explain what you're seeing here is the
- 00:33:49DNA double helix we know that the DNA
- 00:33:52double helix encodes messenger rnas
- 00:33:56which is that purple line pointing up to
- 00:33:59the top of the screen and the messenger
- 00:34:01rnas then encode proteins and it's the
- 00:34:03proteins in the cell that mediate most
- 00:34:05of functions and changeing gene
- 00:34:09expression is an important way in which
- 00:34:11cells change in a very stable way and
- 00:34:14the best analogy I like to use is when
- 00:34:16you go to the gym to exercise the reason
- 00:34:18you're you get stronger is because every
- 00:34:20muscle cell in a muscle bundle upon use
- 00:34:24that cell makes more muscle proteins
- 00:34:27because the gene gen expression of those
- 00:34:28cells of those genes is increased to
- 00:34:31make more mes RNA more protein the
- 00:34:33muscle cell gets bigger the entire
- 00:34:35muscle gets bigger and stronger and in
- 00:34:38the same way those changes occur in
- 00:34:40nerve cells in the brain and that's how
- 00:34:42we learn and we think that drugs of
- 00:34:44abuse represent a maladaptive type of
- 00:34:47learning where through changes in gene
- 00:34:49expression uh very long lasting uh
- 00:34:53maladaptations occur like a shrinkage of
- 00:34:55dopamine cells like a growth of new CN
- 00:34:57es that mediate some of the pathologies
- 00:35:00associated with addiction I think Amir
- 00:35:02is going to talk more about that well
- 00:35:04thank you for introducing air because I
- 00:35:08actually already did but um we've
- 00:35:10already seen a lot about how adult
- 00:35:14brains and and an addiction but you've
- 00:35:17got some amazing statistics actually on
- 00:35:19gateway drugs right so uh part of my
- 00:35:21work was to look at the effect of um
- 00:35:24nicotine on cocaine because uh I think
- 00:35:26more and more not see addiction as a
- 00:35:29developmental disorder we think about
- 00:35:31addiction uh as something that just
- 00:35:33happens to adults but in truth is it
- 00:35:36really has its root stem in adolescence
- 00:35:39that when first that's when first people
- 00:35:41most of the people who become addicted
- 00:35:42try drugs um what percentage of addicts
- 00:35:45get addicted in adolescence um so I
- 00:35:47think for example 90% of people who will
- 00:35:50become smokers start smoking before
- 00:35:52they're 18 and only 10% will become
- 00:35:55smoker if they start to smoke after the
- 00:35:56age of 18 so that's like a very it's a
- 00:35:59massive difference U but it's not only
- 00:36:01for cigarettes or nicotine it's also
- 00:36:03true for other elicit drugs and for
- 00:36:06example if you start uh using an elicit
- 00:36:08drug before you're 18 you're 20 you have
- 00:36:10a chance of we have a 25% chance of
- 00:36:12becoming addicted but if you start using
- 00:36:15an elcd drug after the age of 21 you
- 00:36:17only have a 4% chance of becoming
- 00:36:19addicted so adolesence is um is a
- 00:36:23crucial time for the development of
- 00:36:25addiction and I started to become very
- 00:36:28interested in that because I looked at
- 00:36:29the effect of nicotine on cocaine and I
- 00:36:32found that actually nicotine has a very
- 00:36:34unique ability to um basically loosen
- 00:36:37the DNA and Eric was talking about gene
- 00:36:40expression and when that DNA is loosened
- 00:36:43what happens is that when cocaine comes
- 00:36:44along then genes that are related to
- 00:36:47addiction and this work is very much
- 00:36:48relies on Eric nesler's work um then
- 00:36:51there's a much more massive increase of
- 00:36:53Gene U of gene expression that's related
- 00:36:56to addiction wait so your saying that if
- 00:36:59I get this right 97% of cocaine users
- 00:37:02smoke first right so that's basically
- 00:37:04that's another Finding it's like
- 00:37:06basically people go through a certain
- 00:37:08sequence and I remember I had one of my
- 00:37:10patients my one of my first patients in
- 00:37:12residency and he described to me he had
- 00:37:15when I saw him he had uh cocaine induced
- 00:37:18psychosis I remember how he walked into
- 00:37:20the ER if it were yesterday he was very
- 00:37:22guarded he wouldn't speak um he he was
- 00:37:2525 years old and he was was he was
- 00:37:28completely like he basically blurted
- 00:37:30something about wanting to kill himself
- 00:37:31before others get to him and we admitted
- 00:37:34him to the floor and I remember that
- 00:37:35time I didn't have an appreciation to
- 00:37:37that part of his history because he said
- 00:37:39that he started smoking when he was 12
- 00:37:42um he came from a very affluent family
- 00:37:44in greenish Connecticut and his parents
- 00:37:46divorced and he didn't have a lot of
- 00:37:47supervision he started smoking at 1200
- 00:37:49and drinking but at the time he was 15
- 00:37:52he started smoking marijuana and by the
- 00:37:53time he was 16 and a half he started
- 00:37:55using cocaine and then that's when his
- 00:37:57life went from wor from really bad to
- 00:37:59horrible and worse and he was a Castaway
- 00:38:02teen and and then he dealt with a lot of
- 00:38:05other really horrible consequences but I
- 00:38:07didn't pay attention at the time to the
- 00:38:09fact that he followed a very specific
- 00:38:11sequence of events he started smoking
- 00:38:13and drinking and then he went on to
- 00:38:15marijuana and then he went on to cocaine
- 00:38:17and in my research I started looking at
- 00:38:20the effect of nicotine specifically on
- 00:38:22cocaine and I found that nicotine has
- 00:38:24this effect that it increases gene
- 00:38:27expression
- 00:38:28that's related to addiction one of the
- 00:38:30genes is the FB Gene is it just for
- 00:38:32cocaine um so we haven't actually now we
- 00:38:34haven't looked at other drugs but the
- 00:38:36mechanism the fact that it opens up the
- 00:38:39DNA that he loosens the DNA and enables
- 00:38:41expression more suggests that it could
- 00:38:43possibly do it also for other drugs I
- 00:38:45mean it would it would it otherwise I'm
- 00:38:47it it sort of scientifically strange to
- 00:38:50think that you know nicotine would only
- 00:38:53make you more susceptible to be a
- 00:38:55cocaine addict you know not a meth
- 00:38:57addict so actually we looked at
- 00:38:58methamphetamine and it also has the same
- 00:39:00effect with methampetamine with
- 00:39:02methampetamine what about heroin so we
- 00:39:04haven't looked at that yet but maybe I
- 00:39:06mean how do you know it's causal I mean
- 00:39:07maybe you know an addict's an addict
- 00:39:09right so now other people are looking at
- 00:39:11alcohol and to see whether that also has
- 00:39:13the same whether it works through the
- 00:39:14same system of loosening up the DNA that
- 00:39:17increases the expression of the the
- 00:39:19effect of other um other drugs later on
- 00:39:22but what I found actually later in
- 00:39:24adolescence was something very different
- 00:39:25I didn't expect that I thought that
- 00:39:27nicotine would do that even more so in
- 00:39:29adolescent but I found something very
- 00:39:31different because when I looked at the
- 00:39:33Adolescent brain uh at basine I saw that
- 00:39:37the G the the DNA was already loosened
- 00:39:39up in that particular area in the brain
- 00:39:41in the nuclear circum so at Baseline the
- 00:39:43Adolescent brain is much more sensitive
- 00:39:45to the effect of almost any other drug
- 00:39:47of abuse and so if you um expose the
- 00:39:50Adolescent brain to any any of those
- 00:39:52drugs you'll get more of that growth
- 00:39:55that Eric described because the DNA is
- 00:39:57more open basically open to soaking up
- 00:39:59new
- 00:40:00experiences and to so more of that brain
- 00:40:03change that you were just talking about
- 00:40:05happens in adolescent brains who abuse
- 00:40:07drugs and alcohol there's a good reason
- 00:40:09to believe that because that DNA is more
- 00:40:11loose and that you would get more
- 00:40:12expression and more growth and a
- 00:40:14stronger propensity to addiction and
- 00:40:16that would agree with the fact that so
- 00:40:18why are 25% of people like more like
- 00:40:20likely to get addicted to a drug if
- 00:40:22you're exposed I think we're going to
- 00:40:24see a video of that the DNA so this is a
- 00:40:28compact DNA um that you see that often
- 00:40:31time in in adults and what I saw in
- 00:40:34adolescence was something was a very
- 00:40:36different picture was something more
- 00:40:37like that a much looser DNA so the the
- 00:40:41the gene expression so the genes that
- 00:40:43are over there basically can get
- 00:40:45expressed a lot more in that particular
- 00:40:49stance when it's more loose the DNA is
- 00:40:51more at what age do they revert to the
- 00:40:54adult sort of picture so the work that I
- 00:40:58do is is in um is basically basic
- 00:41:00science work is in animal models in mice
- 00:41:02and in mice I see that this change uh
- 00:41:06reverts back um I guess the human
- 00:41:08equivalent will be around
- 00:41:1025 something like that and yeah the a
- 00:41:13younger brain is more resilient as you
- 00:41:15said and more able to recover so it's a
- 00:41:17it's a bit of a dual-edged sword right
- 00:41:20the plasticity can go both ways adaptive
- 00:41:22and maladaptive okay so he can learn
- 00:41:25much more like M so can he has this
- 00:41:28capacity to learn uh in a in an amazing
- 00:41:31way datalist brain but uh but he also
- 00:41:34has the capacity to change and it's more
- 00:41:37plastic and of course when you talk
- 00:41:39about an adolescent experence
- 00:41:40experimenting with drugs or alcohol
- 00:41:42you're talking about you know I don't
- 00:41:44know how many teenagers I've interviewed
- 00:41:46and you know it can't ever happen to me
- 00:41:48nothing bad will ever happen to me I
- 00:41:50mean this sort of inferiority not
- 00:41:53inferiority complex the the exact
- 00:41:55opposite of that actually um I I'm not
- 00:41:58vulnerable this invulnerability right so
- 00:42:01I like to call that the the Daredevil
- 00:42:03brain the D brain devil brain and so I
- 00:42:08because I'm a child psychiatrist and I
- 00:42:09think that that time that age adolesence
- 00:42:12is a key to study and understand a lot
- 00:42:14of the molecular processes that happen
- 00:42:16in the brain so I started after I saw
- 00:42:18this finding that the Adolescent brain
- 00:42:20is just so different than the adult
- 00:42:22brain I started looking at other
- 00:42:24molecules and part of what I'm finding
- 00:42:26now is some of the very some of the
- 00:42:28molecules that are responsible for
- 00:42:30encoding fear in adults are expressed a
- 00:42:33lot less in the Adolescent brain so even
- 00:42:36the very Machinery that encodes fear is
- 00:42:39expressed Less in the Adolescent brain
- 00:42:41so you can try to scare them until the
- 00:42:43cows come home but the very Machinery
- 00:42:46that exists to actually encode that fear
- 00:42:48is expressed in a much much lower grade
- 00:42:51no we see them all the time even in not
- 00:42:53talking about substance abuse but
- 00:42:54engaging in such teenage risky Behavior
- 00:42:57so you're going to say oh if you do that
- 00:42:58it's going to be horrible something bad
- 00:42:59is going to happen and they were here oh
- 00:43:01risk I want to take that risk I want to
- 00:43:02try it yeah exactly yeah yeah like I've
- 00:43:06got a son about to enter adolescence and
- 00:43:09I'm dreading it because he's got that
- 00:43:10kind of I can do it of course you
- 00:43:14know it really is important to
- 00:43:16understand that this adolescent time is
- 00:43:18so crucial uh for the development of
- 00:43:20this disease because then it has
- 00:43:22implications in terms of prevention in
- 00:43:24terms of intervention in terms of what
- 00:43:25we can do um and and and that's why I
- 00:43:28think it's really it's important to
- 00:43:29understand it's it's a really crucial
- 00:43:31time and think and especially if their
- 00:43:33brains are more plastic and especially
- 00:43:35if intervention can actually help them
- 00:43:37recover more and just one last question
- 00:43:39before we move on to Dr Janda um if if
- 00:43:42if you intervene and get the Adolescent
- 00:43:47help while they're still an adolescent
- 00:43:49in other words is there a better chance
- 00:43:51of success because the brain is so
- 00:43:53plastic or there's better plasticity as
- 00:43:56you put it um and and they Haven it sort
- 00:43:59of settled in and formed and set into
- 00:44:02adulthood brain well I think what
- 00:44:04happens is that like especially
- 00:44:06addiction as we tal it's a chronic
- 00:44:08disease and it takes time to evolve and
- 00:44:10so if you catch it earlier on before it
- 00:44:13gets to the end stage of it then you
- 00:44:15have a much better chance of actually
- 00:44:17preventing it from getting to the end
- 00:44:19stage because sometimes I have like when
- 00:44:21I some of the patients that I see when
- 00:44:23you see them at the end stage it's
- 00:44:25really it's it's it's I think a lot of
- 00:44:27people don't unless you have a a
- 00:44:28personal like experience of it of
- 00:44:30someone that you know they don't really
- 00:44:32realize how horrible they can be I I
- 00:44:34have one patient and now she's an
- 00:44:36alcoholic and now thank God she's been
- 00:44:38sober for many years but at the very end
- 00:44:40stage of her disease she used to drink
- 00:44:42alcohol she had horrible gastritis
- 00:44:44because of the alcohol uh she would buy
- 00:44:46bottles of vodka and then she would
- 00:44:48throw it up but she would want the
- 00:44:50effect of the alcohol so she would
- 00:44:51collect it and drink it again to get the
- 00:44:54effect so this so it's not just
- 00:44:57something that oh I don't have self-will
- 00:44:59anymore it's not about self-will anymore
- 00:45:02it's a very different disease but that's
- 00:45:03at the end stage and it doesn't start
- 00:45:05like that how long had she been drinking
- 00:45:07when she was at that stage she's been
- 00:45:09drinking since she was a teenager and
- 00:45:10she was in her 30s in her 30s it doesn't
- 00:45:13start like that and it can it I think
- 00:45:16some of the findings are that even if
- 00:45:18you do one intake session in research
- 00:45:21you call you call a subject in and you
- 00:45:23you talk to them about their drinking
- 00:45:25history that is enough any self to
- 00:45:27actually change their drinking history
- 00:45:29to change their drinking behavior for a
- 00:45:31few weeks later on they drink less Rec
- 00:45:34just having to sort of go over what have
- 00:45:36you been drinking over the past like
- 00:45:38year or so so that's enough to actually
- 00:45:41even Institute a change well I guess
- 00:45:42because that would force you to you know
- 00:45:45I think a lot of addicts avert their
- 00:45:46eyes like I you know or tomorrow
- 00:45:48tomorrow I'll wipe the Slate clean and
- 00:45:51get up and run 10 miles and B a cake and
- 00:45:55you know go be fantastic at my job and
- 00:45:58whatever um but it I think if you have
- 00:46:00to just sit and tell somebody what you
- 00:46:02drank or what you did it makes you fully
- 00:46:06accountable for your own behavior and
- 00:46:08you're less able to avert your eyes from
- 00:46:10it I think like like one uh that patient
- 00:46:12recites one of the sayings in AA is that
- 00:46:15denial is not a raver in Egypt that's
- 00:46:17one of countless sayings in AA yes um I
- 00:46:22also hear that other places though too I
- 00:46:23think it's just denial anyway what did
- 00:46:25you want to add something no because I
- 00:46:27do want to reiterate on the notion as
- 00:46:29we're addressing the problem of
- 00:46:30substance use the most important thing
- 00:46:32that we can do is prevention and for
- 00:46:34prevention strategies to be effective we
- 00:46:36have to Target children and Adolescent
- 00:46:39and and Eric was saying yes it would be
- 00:46:41fantastic if we had a genene or a brain
- 00:46:43that could tell us who's going to become
- 00:46:45addicted and yet we know who are the
- 00:46:47most vulnerable any kid that has a
- 00:46:50mental illness is at a much higher risk
- 00:46:52of use of substance than any others so
- 00:46:55one of the strategies that is very very
- 00:46:57relevant is to be able to identify when
- 00:47:00you have a kid that's taking drugs to
- 00:47:03rule out whether there is an underlying
- 00:47:05mental illness that's driving the use of
- 00:47:07drugs because again one of the meats
- 00:47:09that a lot of people have is people take
- 00:47:11drugs in order to feel high and have a
- 00:47:13good time but a lot of people take drugs
- 00:47:15in order to feel better and so you have
- 00:47:18an indicator if you already have a
- 00:47:21teenager consuming high doses of drugs
- 00:47:24you want to be able to rule out the
- 00:47:26possibility that there is a mental
- 00:47:28illness because if you properly treat it
- 00:47:30then you prevent the escalation further
- 00:47:32you meaning you're talking about
- 00:47:33depression depression anxiety attention
- 00:47:37deficit hyperactivity disorder um I mean
- 00:47:40difficulties with
- 00:47:43extraversion all of these put a higher
- 00:47:47risk for the kid to take drugs because
- 00:47:49they they may basically want to to to
- 00:47:52fit better and so they may take drugs in
- 00:47:54order to do that or to just feel better
- 00:47:56if you're very anxious and you drink
- 00:47:58alcohol that calms you down if you take
- 00:48:00marijuana that calms you down if you
- 00:48:02have ADHD and you cannot sustain
- 00:48:04attention you take cocaine that will
- 00:48:06temporarily help you so this is
- 00:48:09something that right now we can do and I
- 00:48:12think again emphasizes the importance of
- 00:48:16doing prevention measures because
- 00:48:18clearly all of the data has shown that
- 00:48:21substance abuse can be prevented we've
- 00:48:23been very good with tobacco not perfect
- 00:48:26but we've brought it down by 50% in
- 00:48:28teenagers in less than 10 years so
- 00:48:31prevention strategies work and to bring
- 00:48:34screening and prevention into Primary
- 00:48:36Care absolutely screening for uh when
- 00:48:39you go to a doctor doctors should ask uh
- 00:48:42how much alcohol you're drinking you SM
- 00:48:44actually that like two like 2% of a
- 00:48:47doctor's education deals with substance
- 00:48:49abuse I mean it it's amazing how many
- 00:48:52doctors don't ask y they're not trained
- 00:48:56they're not trained to recognize it so
- 00:48:58as a medical student you never really
- 00:48:59are taught how substance abusers come
- 00:49:02you feel embarrassed because it's highly
- 00:49:04steti how how am I going to ask this old
- 00:49:07lady whether she's drinking more I mean
- 00:49:10there is there is that that absolutely I
- 00:49:12mean I mean it is unfortunate but it is
- 00:49:15the truth so you rather not ask and then
- 00:49:17if you ask and they tell you yes I'm
- 00:49:19drinking one half a bottle of whiskey a
- 00:49:22day do you really want to know what are
- 00:49:23you going to do well and I actually had
- 00:49:26a doctor doctor tell me once in an
- 00:49:27interview that whenever he would ask a
- 00:49:29patient how much he or she was drinking
- 00:49:31every day double it you double or triple
- 00:49:34yeah like nobody ever tells the truth
- 00:49:36it's like oh no I only had one glass of
- 00:49:38wine you know you know but the glass was
- 00:49:41like a a Big Gulp cup you know so but
- 00:49:46also I also think that with adolesence
- 00:49:47it's even more of a problem because
- 00:49:49adolescence you're program not to tell
- 00:49:51your parents everything no one tell no
- 00:49:53adolesence tells their parents
- 00:49:54everything
- 00:49:56important I'm working on an hour on
- 00:49:58children and anxiety and that's an very
- 00:50:00interesting thing to think of it that
- 00:50:01way that if you if we were more aware of
- 00:50:04the fact that anxious kids uh kids who
- 00:50:06are are depressed or have ADHD would be
- 00:50:09kids who would be much more um
- 00:50:12susceptible to turning to something
- 00:50:16altering to make them feel better I
- 00:50:18think we could it would be a big step
- 00:50:19forward towards prevention another big
- 00:50:21step toward prevention obviously would
- 00:50:23be a vaccine and we've seen sometimes in
- 00:50:25Vivid frightening detail how addiction
- 00:50:27can alter the brain in so many ways Dr
- 00:50:29Kim Janda and his team have developed a
- 00:50:32vaccine to block the effect of heroin
- 00:50:35tell us about this Dr
- 00:50:37Janda well um we've context we've been
- 00:50:41developing a number of vaccines I
- 00:50:42originally started developing a cocaine
- 00:50:44vaccine back in the late 80s and then we
- 00:50:47moved into nicotine uh we've done
- 00:50:49methamphetamine but heroin over the last
- 00:50:52five years we've been something we've
- 00:50:53been working hard on um we I was mainly
- 00:50:56interested interested in developing the
- 00:50:57heroin vaccine actually for um third
- 00:50:59world countries really yeah why um well
- 00:51:04actually if you look there's a been a
- 00:51:06increase in
- 00:51:08HIV with heroin abuse because uh sharing
- 00:51:11of needles and so there and so in places
- 00:51:14like in Africa places like Russia they
- 00:51:17don't have exchangeable needles even
- 00:51:18China it's frowned upon they don't have
- 00:51:20methodone clinics and so um vaccines
- 00:51:24over the do we have that slide can show
- 00:51:27vac the
- 00:51:28history um yeah vaccines have kind of
- 00:51:31taken a back seat and uh they've been
- 00:51:34known for Chinese employing variation
- 00:51:36since the year 1000 it's kind of amazing
- 00:51:39because what they used was dry pules and
- 00:51:41they would snort it oh but think about
- 00:51:45that actually vaccines nowadays flu
- 00:51:47vaccines are actually inhaled they're
- 00:51:50internasal this was known back in
- 00:51:52thousands of years ago people have used
- 00:51:54this um vaccines are very inexpensive
- 00:51:56ensive um I would easily argue that the
- 00:51:59two greatest advances over the last 75
- 00:52:01years have been
- 00:52:03antibiotics and vaccines polio so how
- 00:52:07did these vaccines work I mean how does
- 00:52:10a heroin vaccine work how does a heroin
- 00:52:12vaccine work so um yeah considering as
- 00:52:16my colleagues have talked about uh the
- 00:52:18reason why we started to develop
- 00:52:19vaccines is because you've seen the
- 00:52:20complexity of the brain um and trying to
- 00:52:23develop uh specific agonists or
- 00:52:25antagonist for these receptors and
- 00:52:27there's not just a single receptor
- 00:52:29that's controlling addiction for let's
- 00:52:31say cocaine or Methamphetamine or heroin
- 00:52:34uh the other U thing I want to bring up
- 00:52:36is heroin is not the drug heroin's a pro
- 00:52:39drug the real drug is what's called six
- 00:52:42AAL morphine which then morphs into
- 00:52:44Morphine Morphine is then the actual
- 00:52:47drug um and the reason why heroin is
- 00:52:50made is because it crosses the blood
- 00:52:51being buried very quickly heroin has a
- 00:52:53very short halflife in the body it's
- 00:52:55like 20 30 seconds um and so in creating
- 00:52:59these vaccines we have to look at how
- 00:53:01the drug interacts with the body and how
- 00:53:03the body interacts with the drug so it's
- 00:53:05a little bit different than developing a
- 00:53:06vaccine let's say against influenza or
- 00:53:09HIV uh it doesn't have doesn't the
- 00:53:13immune system is programmed basically to
- 00:53:16remove foreign Invaders um our immune
- 00:53:18system was not developed to say cocaine
- 00:53:21is foreign or heroin is for foreign
- 00:53:22maybe 10,000 years from now our our
- 00:53:24immune system will be more highly veled
- 00:53:26and say well yeah maybe those are
- 00:53:28foreign substances so it doesn't it
- 00:53:29doesn't recognize that so what we did
- 00:53:32over the years is tried to develop ways
- 00:53:35to stimulate our immune system to
- 00:53:37recognize drugs of abuse as being
- 00:53:39foreign and this is just for drugs or
- 00:53:41could this also well actually um uh I've
- 00:53:45developed a vaccine uh for obesity
- 00:53:48too um if you want to get into we can
- 00:53:50talk about that later I know people are
- 00:53:52more interested in that but um uh well I
- 00:53:55shouldn't say more interested but it's
- 00:53:56another aspect but uh but vaccines you
- 00:53:58know the way we use the word vaccine is
- 00:54:01you take it before you so you don't get
- 00:54:02the problem I mean I don't understand
- 00:54:05you take this vac that's I mean that's
- 00:54:06true in one sense but vaccines are being
- 00:54:08developed now for like staff or um uh
- 00:54:11other bacterial diseases where you may
- 00:54:13have the problem you can take the
- 00:54:14vaccine to clear the infection so that's
- 00:54:16not completely true that it's it's not
- 00:54:19preventive it's also going to be
- 00:54:20therapeutic uh so the vaccines aren't a
- 00:54:24typical vaccine like you'd say for polio
- 00:54:25you get a shot maybe wouldn't have to
- 00:54:27have another one for many years the
- 00:54:29vaccines um have to be given over a
- 00:54:32period of several weeks and then you
- 00:54:34build up an immunity to the drug and
- 00:54:36then it'll last for a period of time and
- 00:54:37just like if you a foreign Invader of
- 00:54:40bacteria you it takes a little bit of
- 00:54:42time to clear the infection our own
- 00:54:43immune system could do that and it'll do
- 00:54:45Wan off the same thing with the drugs
- 00:54:47it'll it'll Wan off and then you have to
- 00:54:49re be reboosted it'll it'll kick back up
- 00:54:51again but so what it does is remove the
- 00:54:54effect of the drug no what it does is um
- 00:54:56do we have that one picture showing the
- 00:54:58the the
- 00:54:59brain oh right there so you you see the
- 00:55:03little red dotted lines at the neck uh
- 00:55:05the immune system typically doesn't
- 00:55:07cross the bloodb brain barrier it's not
- 00:55:09privileged to do that so what the
- 00:55:10vaccine does is it blocks the drug from
- 00:55:14crossing the blood brain barrier in some
- 00:55:16cases depending on the drug just like I
- 00:55:17said how the drug reacts with the body
- 00:55:18the body reacts with the drug you can
- 00:55:20create a vacuum and it can pull the drug
- 00:55:22out of the brain depending on how
- 00:55:24strongly these antibodies bind the drug
- 00:55:25so if somebody had taken the vaccine and
- 00:55:27then decided they still wanted to go do
- 00:55:29heroin What would happen to that person
- 00:55:31what would happen that if the vaccine
- 00:55:33worked well they wouldn't they wouldn't
- 00:55:35get the potential psychoactive effects
- 00:55:37for the drug but wouldn't you still have
- 00:55:39the potential life-threatening effects
- 00:55:41of the drug lifethreatening you mean of
- 00:55:44overdose of right um actually with the
- 00:55:47heroin vaccine we haven't published this
- 00:55:49data but we've we've um in rodent models
- 00:55:52we've gone as high
- 00:55:53as uh 35 to 40 migs per kig of heroin
- 00:55:58and typically four migs will kill an
- 00:56:01animal and they're perfectly fine
- 00:56:03they're happy as little clams running
- 00:56:05around so they have no effect so this is
- 00:56:08actually it's kind of interesting
- 00:56:10because with this vaccine that we've
- 00:56:11developed here um it could be used as a
- 00:56:16overdose therapy too at the same time
- 00:56:18right here in New York City actually
- 00:56:19right now the police officers I think
- 00:56:21just last week are now equipped with the
- 00:56:24shots for when overdoses I'm just I'm
- 00:56:28asking only because it I I it raises the
- 00:56:30concern that if somebody's on the
- 00:56:32vaccine and they think I want to get
- 00:56:34high um and dog G it this didn't do
- 00:56:37enough I'm I'm going to keep doing more
- 00:56:39and more and more and try and override
- 00:56:40my vaccine and kill themselves in the
- 00:56:42process so as we' heard the vaccine is
- 00:56:45to be used when people have lapses so it
- 00:56:48will prevent a relapse that's where we
- 00:56:50see the importance of it um that uh like
- 00:56:54you heard uh maybe you hear particular
- 00:56:57song or a particular place a particular
- 00:56:59smell and you take the drug you know a
- 00:57:02taste of the drug and then what happens
- 00:57:04is you're going to relapse maybe but the
- 00:57:06vaccine if in place would prevent that I
- 00:57:10mean there's there are potential caveats
- 00:57:12where one could say well you could take
- 00:57:13more and more of the drug to surmount it
- 00:57:16and that's that's a possibility because
- 00:57:18the the vaccines are like little sponges
- 00:57:19they can only take up so much you have
- 00:57:21to ring those guys out um so depending
- 00:57:25on the the drug they they're all
- 00:57:27different so not one vaccine is the same
- 00:57:28for all drugs it's it's it's different
- 00:57:31but in with regards to heroin it's very
- 00:57:33special because as I said it's heroin
- 00:57:36morphs itself into multiple different
- 00:57:38drugs before it gets into the brain and
- 00:57:40so you don't have many of the issues
- 00:57:41like you have with cocaine or
- 00:57:43Methamphetamine that lasts very long
- 00:57:44periods of time if you can stop it from
- 00:57:46getting across the bloodb brain barrier
- 00:57:49you can kind of win the battle because
- 00:57:50once it's over there it doesn't come out
- 00:57:51easily morphine doesn't cross readily it
- 00:57:53doesn't go across easily either so you
- 00:57:56there's some advantages with some of
- 00:57:58these vaccines that that um depending on
- 00:58:00the drug they could have for like
- 00:58:01overdose where in certain ones they
- 00:58:03can't I in I I did a story on mothers in
- 00:58:08rehab um and most of them were there for
- 00:58:10alcohol abuse but um we there was one
- 00:58:13woman who was there for heroin addiction
- 00:58:16and she said that heroin was the most
- 00:58:18addictive drug is that
- 00:58:22true um you know I'm not a clinician but
- 00:58:25um I know when we put these animals on
- 00:58:28long-term AIS for heroin they just look
- 00:58:30terrible from The Other Drugs we've used
- 00:58:32Like Cocaine methamphetamines really
- 00:58:35quite bad too but heroin they just look
- 00:58:38awful um we think that heroin and
- 00:58:40stimulant stimulants would be cocaine
- 00:58:43and
- 00:58:43methamphetamine amphetamine are probably
- 00:58:46the most addictive it's a really hard
- 00:58:49question makes something more addictive
- 00:58:51versus a hard question to answer because
- 00:58:53we would have to do a study and it would
- 00:58:55be impossible to do it go to a large
- 00:58:57State University campus 40,000 kids
- 00:59:01treat a thousand of them with Heroin a
- 00:59:04thousand of them with amphetamine a
- 00:59:05thousand of them with marijuana and then
- 00:59:08stop it suddenly and see how many are
- 00:59:10hooked that's a good study to fund but
- 00:59:14you know
- 00:59:15so you can't do the study but you can't
- 00:59:18answer the question without a study like
- 00:59:20that so we're left really not knowing
- 00:59:23how intrinsically addictive each of
- 00:59:25these substan is is but there are some
- 00:59:27indirect uh data that gives you an
- 00:59:30incline in terms of how addictive drugs
- 00:59:32are for example the epidemiologists who
- 00:59:35like to measure everything that they can
- 00:59:36get their hands on actually assess the
- 00:59:39number of people the percentage of
- 00:59:40people that when they get exposed to a
- 00:59:42drug will become addicted to them and
- 00:59:44then they rank them and interestingly
- 00:59:46the drug that comes on top is actually
- 00:59:48nicotine but that's that has a caveat
- 00:59:51because nicotin is legal so it's a
- 00:59:53widespread availability increases the
- 00:59:55lik hood that you will be repeatedly
- 00:59:57administering it but if you take just
- 01:00:00the illegal drugs um heroin actually has
- 01:00:03the highest percentage something like 25
- 01:00:06to 30% of people that get exposed to
- 01:00:08herin will become addicted and then if
- 01:00:11you take those numbers you have a
- 01:00:13methamphetamin is also highly addictive
- 01:00:15and and and then marijuana is probably
- 01:00:20has the lowest rate and it's only 9% of
- 01:00:23people that get exposed will become
- 01:00:24addicted but also depends at what age so
- 01:00:27if you are less than 18 60% of them will
- 01:00:31become addicted to to marijuana so that
- 01:00:33gives us a sense in population basis how
- 01:00:36do they spare one versus the other
- 01:00:38considering just elicit substances then
- 01:00:41we have another way clinically to try to
- 01:00:44determine which is when you start to
- 01:00:45take the drug regularly how much time
- 01:00:48does it take you to escalate until lose
- 01:00:51control and in that one metamphetamine
- 01:00:53is probably one of the fastest drugs
- 01:00:56within less than one year you can get
- 01:00:58people very very severely addicted but
- 01:01:01opiates also create these very fast
- 01:01:04escalation and finally the animal models
- 01:01:07so what we we assign the addictiveness
- 01:01:10of drugs to their ability to their
- 01:01:11potency to increase dopamine in the
- 01:01:13brain and of all of the drugs the most
- 01:01:16potent drug that we currently know in
- 01:01:18terms of its ability to increase
- 01:01:20dopamine is metamphetamine so you take
- 01:01:23all of this information and you come
- 01:01:24exactly to the conclusion of what Eric
- 01:01:26was saying that probably the most
- 01:01:29addictive drugs that we have independent
- 01:01:31of the F legality or not legality have
- 01:01:34to do with methamphetamine and and and
- 01:01:36heroin that's that's what I and cocaine
- 01:01:39also is a high but but there it
- 01:01:41goes and getting back to the the other
- 01:01:44point too is how these drugs are being
- 01:01:47taken so um you know in the 70s they
- 01:01:51were going to try to legalize cocaine if
- 01:01:53you go back to the Carter and and
- 01:01:56looking at that and it wasn't until I
- 01:01:58think it was 84 which crack hit the
- 01:02:01scene and crack is nor will tell you is
- 01:02:03extremely addictive and people have this
- 01:02:05misconception what crack is crack is
- 01:02:07cocaine you you just you take cocaine
- 01:02:09you heat it up sodium bicarb let it
- 01:02:11crystallize out get these large crystals
- 01:02:13it's smoked and the thing about that is
- 01:02:15smoking it gets the bra brain much
- 01:02:17quicker than snorting it or injecting it
- 01:02:19and so like that or with methamphetamine
- 01:02:22these people go on these runs for
- 01:02:24several days taking it in um so again
- 01:02:27depending on the drug can impact how
- 01:02:29you're seeing the the addiction take
- 01:02:31place um the other thing is is
- 01:02:33interesting is kind of cost supply and
- 01:02:36demand so with Heroin when we see uh
- 01:02:40more drug enforcement in terms of
- 01:02:41bringing it in the country we also see
- 01:02:43an increase of what's called synthetic
- 01:02:45opioids so things things like fentanyl
- 01:02:48which was made in the 60s it's about 100
- 01:02:50to 500 times more potent than uh
- 01:02:54morphine it's actually probably not more
- 01:02:57potent it just crosses the blood brain
- 01:02:58barrier easier it's very easy to make so
- 01:03:00there's you know we've all seen breaking
- 01:03:02bad there's these Rogue chemists out
- 01:03:03there who are making this you've heard
- 01:03:05of things like China White so what
- 01:03:07happens when when the heroin demand you
- 01:03:09know so heroin's not pure it's it's cut
- 01:03:10up with different things and you can use
- 01:03:13very small amounts of of these synthetic
- 01:03:15opioids to give the addict the so-called
- 01:03:18need and so that's another thing that I
- 01:03:20think we have to contend with is is that
- 01:03:23these other things are being mixed in so
- 01:03:25you say well he overdosed in heroin that
- 01:03:27may not be potentially true he could
- 01:03:29have overdosed on one of the synthetic
- 01:03:31opioids also involved getting back to
- 01:03:33your vaccines have they been tested on
- 01:03:35humans they have uh cocaine and nicotine
- 01:03:38have have been have gone are gone are in
- 01:03:41clinical trials and when might these
- 01:03:43things hit a market hit the market um
- 01:03:46well when the FDA feels they're good
- 01:03:48enough to be approved that's some of
- 01:03:50them are are still uh uh they're still
- 01:03:53uh lacking in terms of getting the
- 01:03:56immune response strong enough there's a
- 01:03:58lot of variability as you might
- 01:03:59obviously diversity in our population
- 01:04:01and and so the vaccines can work well on
- 01:04:04some people and don't work so well in
- 01:04:06others um so those are some things that
- 01:04:08we need to look at a little more closely
- 01:04:11um and the other big thing is you're
- 01:04:13saying how quickly we can move these
- 01:04:14things forward um I don't know any drug
- 01:04:17company that's working on any of these
- 01:04:19vaccines except for one company that's
- 01:04:21working on nicotine they will not work
- 01:04:23on any of these heroin I have
- 01:04:26tried to go to Every major company
- 01:04:30biotech companies Wall Street people
- 01:04:32saying hey would you be interested in
- 01:04:35funding a heroin vaccine moving forward
- 01:04:37that we could develop and it's really
- 01:04:39they're saying wow this is really
- 01:04:40interesting you know I I knew someone
- 01:04:42that overdosed on this um it's great
- 01:04:44work you're doing fantastic but H we
- 01:04:48just don't see a market for
- 01:04:51it really it's they cost it's it's how
- 01:04:55much they think they're going to get
- 01:04:56back but there clearly is a market for
- 01:04:59it and drug companies want profits I
- 01:05:01mean why wouldn't they want to Market
- 01:05:03something that they could readily sell
- 01:05:07sell I you know what it maybe you know I
- 01:05:10don't know a lot of hmos that cover you
- 01:05:13know crack addicts or heroin addicts so
- 01:05:15nicotine smoking one thing but they're
- 01:05:18not you know in terms of what they're
- 01:05:21going to get back if they're going to
- 01:05:22try to go forward and make this minorcan
- 01:05:24comment more but the develop of
- 01:05:26vaccine the vaccine itself is extremely
- 01:05:28inexpensive that's why I thought for
- 01:05:30third world countries for her once you
- 01:05:32have the vaccine made it's inexpensive
- 01:05:34but to move these through clinical
- 01:05:36trials cost probably 40 $50 million at
- 01:05:40the end of the day and so for them to
- 01:05:42put that investment in that and what
- 01:05:44they're going to get back in return is
- 01:05:46what drives these things I think and so
- 01:05:50yeah the value is there and you know you
- 01:05:53asked me at the beginning about policy
- 01:05:54issue and this is is one of the most
- 01:05:56sensitive ones because the science in
- 01:05:58the whole field of substance abuse is
- 01:06:00Advanced to the point that we could have
- 01:06:02much better intervention not just based
- 01:06:04on immunotherapies vaccines and
- 01:06:06monoclonal antibodies but actually on
- 01:06:09medications but we have this huge gap
- 01:06:11because the pharmaceutical industry does
- 01:06:14not feel that there is a profit to be
- 01:06:16made on the development of this uh type
- 01:06:19of medications now this was reviewed
- 01:06:21many years ago more than 15 years ago by
- 01:06:24The Institute of Medicine that came back
- 01:06:26and said there should be an
- 01:06:28incentivization of the Pharmaceuticals
- 01:06:30to go after that just like we've done in
- 01:06:32vac vaccines in this country if you
- 01:06:34don't incentivize the companies are not
- 01:06:36going to develop vaccines for many of
- 01:06:38the diseases of childhood my perspective
- 01:06:41is you are not going to be making money
- 01:06:43with tanks but if there is a war you
- 01:06:46need to develop tanks and you then
- 01:06:48create an incentive because this is that
- 01:06:51was mood lighting everybody phal company
- 01:06:55yes no
- 01:07:00so the bottom line is that that this is
- 01:07:02an issue where if we were to create
- 01:07:05incentives that actually would cost no
- 01:07:08money to the government you just for
- 01:07:10example increase the patent that they
- 01:07:12could get and theom had a whole list of
- 01:07:14incentives that could be made to
- 01:07:16accelerate the process what Kim is
- 01:07:19saying is actually very very relevant
- 01:07:21with respect to uh the heroin vaccine
- 01:07:24because the the injection of heroin is
- 01:07:28the number one driver of the HIV
- 01:07:30epidemic in many countries in the world
- 01:07:34and yet this could be completely averted
- 01:07:37if there was a treatment intervention
- 01:07:40such as a vaccine for heroin and so so
- 01:07:43we what is very exasperating is that you
- 01:07:46have the knowhow you have the knowledge
- 01:07:48you know the road but there is not the
- 01:07:51resources to move forward in that road
- 01:07:54and yet you know that the cost of not
- 01:07:56moving forward in that row are just
- 01:07:58gigantic so that's a little bit of the
- 01:08:00issues that we play with policy on a
- 01:08:02field that is
- 01:08:04stigmatized so it's stigmatized in the
- 01:08:06healthcare system and it's not
- 01:08:08considered one that is worthwhile of
- 01:08:10investment by private stigmatized in the
- 01:08:12Health Care system I understand you know
- 01:08:15definitely when you talk to addicts or
- 01:08:19addicts
- 01:08:20families co-workers I you understand the
- 01:08:23stigma but why in the healthcare I mean
- 01:08:26I not saying I agree with that I think
- 01:08:27it's a terrible thing people who are
- 01:08:29drug addicts are difficult patients it's
- 01:08:32they're difficult for the system they're
- 01:08:34difficult for doctors and nurses just as
- 01:08:36they're difficult for their family
- 01:08:38members it's just the it's just it's
- 01:08:40part of the disease and also the other
- 01:08:43thing too they are not disip patients
- 01:08:45because because they are in themselves
- 01:08:47in a lot of turmoil but also because
- 01:08:50there is that belief that they are to
- 01:08:52blame for the consequences of their
- 01:08:54disease and that is
- 01:08:56societ is telling them that yeah but
- 01:08:58that's the Healthcare System says it's
- 01:09:00it's a lifestyle choice and and when I
- 01:09:03came tonight I was I was asking well how
- 01:09:05can an insurance deny the treatment for
- 01:09:08a substance abusers whether it's
- 01:09:09nicotine or it's alcohol and and the
- 01:09:12justification were to one of them there
- 01:09:14are no treatments that work and the
- 01:09:16other one this is a lifestyle Choice
- 01:09:18well a lot of the diseases that we
- 01:09:21develop in chronic many of them are
- 01:09:22related to behaviors that we are doing
- 01:09:25and yet we never question it so so we
- 01:09:28treat Addiction in a different way
- 01:09:30because we have the sense that the
- 01:09:32person is choosing to take these drugs
- 01:09:35is doing them on themselves and then
- 01:09:38coupled to the fact that these
- 01:09:40individuals have a lot of emotional
- 01:09:42disruption and and and because of the
- 01:09:45the way that drugs affect their brain
- 01:09:47they tend to lie they need the drug and
- 01:09:50they will do anything that they can in
- 01:09:52order to get the drug when they are
- 01:09:53actually addicted will you have
- 01:09:55perfectly teed up our second um Seth
- 01:09:57manukan video because he talks about
- 01:09:59willpower the issue of willpower um
- 01:10:02because so much you're right so much of
- 01:10:04the country um the prevailing attitude
- 01:10:07and even people who think oh no it's a
- 01:10:09disease will actually then go ahead and
- 01:10:11treat an addict like you know what get
- 01:10:13your you know what together um I
- 01:10:16actually have a really good example that
- 01:10:17same patient that I described before
- 01:10:19once described to me how while she was
- 01:10:21at work she was reading everyone the
- 01:10:23people were reading the New York posts
- 01:10:25and they were reading about this woman
- 01:10:26that was arrested at the supermarket
- 01:10:28while she was trying to shop for food
- 01:10:30with her kids and she was arrested
- 01:10:31because she was snorting heroin at the
- 01:10:33same time and so most people's reaction
- 01:10:37were oh my God what a horrible mother
- 01:10:39but her reaction my patient was oh my
- 01:10:41God I can't believe she was actually
- 01:10:43able
- 01:10:44to go through with it and try to take
- 01:10:47care of her kids despite this horrible
- 01:10:48illness because when she was when she
- 01:10:51was drinking she didn't want anyone
- 01:10:53around her her kids were with her with
- 01:10:55were with their father and she couldn't
- 01:10:57take care of her kids so I think we all
- 01:11:00have this idea yeah it's an illness but
- 01:11:02then when we see something like that
- 01:11:03it's hard for us to really relate but it
- 01:11:06is an illness and that woman was trying
- 01:11:07to take care of her kids while having a
- 01:11:09really difficult illness trying to
- 01:11:11battle really difficult illness you I
- 01:11:12want to make a comment because just
- 01:11:14because a lot of public here is that you
- 01:11:17know you're asking why haven't some of
- 01:11:18these things move forward quicker and
- 01:11:20part of it is the politicians and the
- 01:11:24money coming in the only person that's
- 01:11:25funding my research is naida right here
- 01:11:29that's it and the money that's coming in
- 01:11:32the NIH has been stagnant for many years
- 01:11:36um it's been the most difficult times
- 01:11:39that I've ever seen in terms of trying
- 01:11:41to get money to do research in these
- 01:11:43areas I used to have a lot of hair and I
- 01:11:45don't have any hair any I'm going to
- 01:11:47start doing research on that
- 01:11:49next um so I think the the part of it is
- 01:11:53with the politicians feel the adct it's
- 01:11:55a moral failure of the individual versus
- 01:11:57the a disease right until they can get
- 01:11:59around that that it's not a moral
- 01:12:01failure they're not going to put more
- 01:12:03money into it if they don't put more
- 01:12:05money into it you know we can't you know
- 01:12:07move forward with some of this stuff so
- 01:12:08I know we're trying to cut taxes and all
- 01:12:10these other things but you know if I
- 01:12:14hate say if the NIH if we don't get more
- 01:12:16infusing money into this our whole
- 01:12:18system academics in TR to doing research
- 01:12:20and and the things I'm trying to do is
- 01:12:21going to collapse
- 01:12:31well said uh let's take a look at this
- 01:12:34video that Seth made on Willpower and
- 01:12:36then I'd like to discuss this with all
- 01:12:37of you that and the stigmatizing of the
- 01:12:39disease of addiction I've had some um
- 01:12:43neuropsychological testing since I've
- 01:12:45been sober uh you know partially to find
- 01:12:50out how my brain works um and the thing
- 01:12:54that really struck me is how valuable
- 01:12:58that information would have been uh you
- 01:13:01know not to me probably but to my
- 01:13:04parents and to um doctors who were
- 01:13:06treating me when I was 15 um and that is
- 01:13:10something that I find very
- 01:13:12exciting this obviously that he makes a
- 01:13:15compelling case for what you just made
- 01:13:17which is that we need to study this but
- 01:13:20you know getting back to that story you
- 01:13:21told about your patient the alcoholic um
- 01:13:24who was so desperate I mean that is such
- 01:13:27a vivid example of the fact that this
- 01:13:29isn't a matter of willpower but how much
- 01:13:32do you bump up against that all of you
- 01:13:34in in in your work I know that in the
- 01:13:37reporting that I've done on this issue
- 01:13:40um and my experience in this issue that
- 01:13:42that is it's a huge thing I mean people
- 01:13:44it's it's a little bit like talking out
- 01:13:45of both sides of your mouth we can all
- 01:13:47say all the right
- 01:13:48platitudes sometimes about how we look
- 01:13:51at the disease of addiction in this
- 01:13:52country but the fact of the matter is we
- 01:13:55we we look we don't look at them the
- 01:13:57same way we look at a cancer patient or
- 01:13:59even you know somebody with diabetes
- 01:14:01it's it's it's not seen that way it's
- 01:14:03seen as something you can control one of
- 01:14:07the troubling aspects of addiction is
- 01:14:09that we think that drugs of abuse
- 01:14:11actually damage the parts of the brain
- 01:14:14that mediate willpower and Free Will and
- 01:14:17the ability to make an informed Choice
- 01:14:20requires the brain functioning correctly
- 01:14:23and it's the drugs that damage the
- 01:14:25brain's ability to do that irreparably I
- 01:14:27don't think irreparably but for a long
- 01:14:30time and it's hard to get over it it's
- 01:14:32in a way I like the metaphor of actually
- 01:14:35because I think it describes it very
- 01:14:36very nicely you're driving in your car
- 01:14:39and you see a cat Crossing and you want
- 01:14:42to break you don't want to hurt the cat
- 01:14:45but if your brakes are not working no
- 01:14:47matter how much you want to stop you're
- 01:14:49not going to be able to stop and you're
- 01:14:51going to hurt someone so the the the the
- 01:14:54real it and I think that's one of the
- 01:14:56reasons why it's so very difficult for
- 01:14:57people to understand even if they
- 01:15:00theoretically say it's a disease of the
- 01:15:01brain because we're all use uh to
- 01:15:04basically have control of our urges we
- 01:15:07all once in a while fail right I mean we
- 01:15:10have to be honest too but most of the
- 01:15:12time we can control our urges so the and
- 01:15:15we also value very much that ability to
- 01:15:18make a decision and carry through so
- 01:15:20it's very difficult to understand that
- 01:15:23that that process
- 01:15:25happens because certain structures in
- 01:15:27the brain are there that allow you to do
- 01:15:29that and if those structures don't work
- 01:15:32even if though you say I'm not going to
- 01:15:34take the drug you don't have the
- 01:15:37neurobiological substrate that will
- 01:15:39allow you to stop just like you have no
- 01:15:41breaks and how quickly after you begin
- 01:15:44to abuse drugs or alcohol do you lose
- 01:15:46that capacity to break well one of the
- 01:15:50things that we were discussing at the
- 01:15:51beginning was the notion to the extent
- 01:15:53that the the vulnerability for addiction
- 01:15:56and for example now we recognize that
- 01:15:58one of the factors that make you more
- 01:16:00vulnerable is if you are born already
- 01:16:03with a a system a frontal system that
- 01:16:06does not enable you to regulate your
- 01:16:08emotions and desires as well so there's
- 01:16:11variability we all have different sizes
- 01:16:14well that work all of our brains work
- 01:16:16differently and there are people that
- 01:16:17are born with stronger or weaker so that
- 01:16:20for example could be a factor that makes
- 01:16:22you vulnerable but the repeated use of
- 01:16:25drugs by themselves can weaken those
- 01:16:28areas of the brain how long it takes
- 01:16:30again is is very variable depends on
- 01:16:32drugs age of initiation and all of these
- 01:16:34things that we have discussed can we
- 01:16:36recover and as Eric said um again we
- 01:16:41that's what we do therapeutically we are
- 01:16:43doing interventions to try to strengthen
- 01:16:46those systems so in the past uh we were
- 01:16:49much more negative now we're developing
- 01:16:52not just therapeutic interventions based
- 01:16:54on Behavior Behavior but a big area on
- 01:16:56science in Neuroscience is the use of uh
- 01:16:59devices like electrical stimulation or
- 01:17:02magnetic stimulation to strengthen
- 01:17:04certain areas so all of these we do that
- 01:17:06already we are doing it there are
- 01:17:08there's research going on to for example
- 01:17:11use these uh stimulation devices for the
- 01:17:13treatment of depression there's research
- 01:17:16using it for the treatment of drug
- 01:17:17addiction to improve executive function
- 01:17:20and there's several there are many
- 01:17:22evidence-based behavioral interventions
- 01:17:24that can help us strengthen executive
- 01:17:26function so so there there is the more
- 01:17:29we know about the brain the better we
- 01:17:32are in in our ability to do tailor
- 01:17:35interventions to try to strengthen
- 01:17:38systems that may be weaken in this case
- 01:17:40by drugs or by other
- 01:17:43circumstances and and yet so much of the
- 01:17:46language that you hear in recovery is
- 01:17:48focused on it seems almost to be like
- 01:17:50willpower like you one day at a time in
- 01:17:53AA and and making those decisions not to
- 01:17:57take drugs or drink I mean trying to
- 01:18:00rebuild those systems in the brain and
- 01:18:02regain control but that's why I keep ask
- 01:18:04and I must have asked this 10 times
- 01:18:06tonight well how long does it take for
- 01:18:08that the brain to rec from person to
- 01:18:11person tremendously and I think one
- 01:18:12important lesson is that people go
- 01:18:16through treatment they fail they should
- 01:18:18go through treatment again and they may
- 01:18:21fail again it doesn't undo the successes
- 01:18:23of the past treatments and sometimes
- 01:18:25people need to go through treatments a
- 01:18:27dozen times before all of a sudden
- 01:18:29something clicks and they're able to
- 01:18:32maintain AB contributes to the stigma
- 01:18:34Associated to the disease doesn't it I
- 01:18:35me relapsing exactly and I think that
- 01:18:39you know is the addict probably begins
- 01:18:42to
- 01:18:42feel you know anguish and Powerless and
- 01:18:46their families and their families
- 01:18:48frustrated impatient get it together MH
- 01:18:51but there's also another aspect that I
- 01:18:53sort of mentioned before is that that um
- 01:18:55there's a much higher risk in
- 01:18:56adolescence and uh and that it doesn't
- 01:18:59start with cocaine it usually starts
- 01:19:00with smoking and drinking and that
- 01:19:03that's an age where we can intervene a
- 01:19:05lot more we actually have well you seem
- 01:19:08to think that you have a little bit of
- 01:19:09power over your kids or that you can
- 01:19:12even other interventions that I know
- 01:19:13that people don't like because it seems
- 01:19:16like an invasion of privacy but like but
- 01:19:18like drug testing for example so we
- 01:19:20really try to shy away from it but it is
- 01:19:22a tool we we would love it in psychiatry
- 01:19:24if we would have tools diagnostic tools
- 01:19:26we hardly have any diagnostic tools we
- 01:19:28it's not like in other areas of medicine
- 01:19:30where we can take blood pressure or
- 01:19:31doing echocardiogram but we do have the
- 01:19:34ability to do drug testing to know
- 01:19:36whether kids have been exposed or not
- 01:19:38exposed especially if they're high risk
- 01:19:39or you see that they've changed their
- 01:19:41behavior um because this idea that maybe
- 01:19:44they'll tell you uh what they're doing I
- 01:19:47think is really it's not very realistic
- 01:19:49if you understand what adolescence is
- 01:19:50about and how to adolescence actually um
- 01:19:53how to adolescence like work in the
- 01:19:55world um but we have certain tools that
- 01:19:58we underutilize I think and if you ask
- 01:20:00all most of the clinicians that I know
- 01:20:02if you ask them about whether children
- 01:20:05like adolescents should be drug tested
- 01:20:07certain adolescent that are at high risk
- 01:20:09you will you get in resounding yes but
- 01:20:11if you ask the public it would seem like
- 01:20:12no that's an invasion of privacy you
- 01:20:15should trust them you should talk to
- 01:20:16them that people have this aversion to
- 01:20:18the idea but you can really know what's
- 01:20:21going on with a teenager it's very
- 01:20:22simple it's a very simple test to do and
- 01:20:24then you'll know what they're exposed to
- 01:20:26and I've had patients um I have one
- 01:20:29patient that by the time she was 16 and
- 01:20:31a half she probably did everything under
- 01:20:33the face of this planet she did heroin
- 01:20:35she did everything and one time she was
- 01:20:37doing some mushrooms in school and she
- 01:20:38had all these epiphanies and she wrote
- 01:20:40it down in a journal and she lost the
- 01:20:42journal she was uh then summoned to the
- 01:20:45to the counselor's office with her mom
- 01:20:47and she had a party that weekend and she
- 01:20:49was like they sent her home she was
- 01:20:51crying and crying and crying on the car
- 01:20:53came home ran
- 01:20:55upstairs UNC uncontrollably sobbing into
- 01:20:58the pillow and then the mother said okay
- 01:21:00she said it's the only first it's the
- 01:21:02first time I've ever tried anything I've
- 01:21:03never done anything sobbing into the
- 01:21:05pillow and the mother said okay I
- 01:21:06believe you it's fine you can go to the
- 01:21:07party and that patient she is an adult
- 01:21:09when she told me the story she said at
- 01:21:11that moment she was like smiling into
- 01:21:13the pillow saying sucker I got her um
- 01:21:16but that patient went on to go to
- 01:21:18college and she was raped and she
- 01:21:20suffered other consequences and you can
- 01:21:23intervene you can intervene in
- 01:21:25adolescence um but we I don't think
- 01:21:27we're utilizing all the tools that we
- 01:21:29have yeah that you mentioned in that
- 01:21:31story I mean we we're obviously focusing
- 01:21:33tonight on the brain and the science of
- 01:21:35addiction but the very real life
- 01:21:37consequences of addiction go you know
- 01:21:39Way Beyond just the damage that you do
- 01:21:41to your body when you're taking that
- 01:21:42drug or too much alcohol but placing
- 01:21:46yourself in positions where I mean so
- 01:21:48that was that's one of there was there's
- 01:21:50a fantastic book by a young woman named
- 01:21:52Corin zelus called smashed story of a
- 01:21:54drunken girlhood and um she was a
- 01:21:57straight A student phenomenal like
- 01:21:59really smart girl who was drinking
- 01:22:02alcoholically from the time she was a
- 01:22:03sophomore in high school and kept it all
- 01:22:06hidden you know as another friend of
- 01:22:08mine Mary Carr who's an amazing writer
- 01:22:11she wrote a book called lit about her
- 01:22:13journey as an alcoholic Harvard
- 01:22:15professor and mother of a son and as she
- 01:22:18said about um alcoholic women pardon the
- 01:22:21language oh we are sneaky [ __ ] you
- 01:22:24know so I mean they're you're dealing
- 01:22:26with you know a a a population that will
- 01:22:30will as you said lie about what they're
- 01:22:33doing for a variety of reasons but you
- 01:22:36know mostly so that they can continue to
- 01:22:37do that so it sounds like what we've
- 01:22:39reached is sort of an impass which is we
- 01:22:42have the stigma that's preventing more
- 01:22:44of the research and funding for more
- 01:22:46research and at the same time if we had
- 01:22:49more science that we would get from the
- 01:22:51research we would have less stigma it's
- 01:22:53like you know how do you how do you
- 01:22:56break that
- 01:22:57impass well I think to break that impass
- 01:23:00with knowledge because I remember when I
- 01:23:02was born in Mexico and I was growing up
- 01:23:04in Mexico and I remember clearly the
- 01:23:05woman the neighbor across and she
- 01:23:08developed cancer and people were
- 01:23:10speaking like in a secret and nobody
- 01:23:12dared to speak out of cancer and I
- 01:23:13remember very clearly how s stigmatized
- 01:23:16cancer was then that disappear and then
- 01:23:19I went into Psychiatry and mental
- 01:23:21illness are still stigmatized where
- 01:23:23addiction continues to be so and I think
- 01:23:26a lot of it is the lack of understanding
- 01:23:28and we have the sense we we because we
- 01:23:31don't really understand how the brain
- 01:23:33works so we have the assumption that a
- 01:23:35lot of our behaviors and thoughts and
- 01:23:38and the capacities that we give for
- 01:23:39granted are automatic and we don't
- 01:23:42realize that they are not until we lose
- 01:23:44them and so it's very difficult to
- 01:23:46conceptualize and I think that one of
- 01:23:48the other aspects that has made it much
- 01:23:50hard very hard for the healthare system
- 01:23:53to to bring It Forward forward as a as a
- 01:23:55as another disease is that we have very
- 01:23:58few medications that we can use in the
- 01:24:00treatment of drug addiction I think if
- 01:24:02we had vaccines I think if we could have
- 01:24:05actually more potent and efficacious
- 01:24:07medications against drug addiction it
- 01:24:09would be much more easy to accept and
- 01:24:12comprehend and and and and that will
- 01:24:14start to erase some of the stigma so I
- 01:24:17so I'm optimistic that knowledge and
- 01:24:20technologies will will change this and
- 01:24:22there has been progress
- 01:24:24the knowledge basee today compared to 20
- 01:24:27years ago is really vast we know a lot
- 01:24:29about the brain a lot about addiction
- 01:24:32and there have been some improved
- 01:24:33treatments and there will be more and as
- 01:24:36the treatments come then the stigma will
- 01:24:38be reduced but but they are very I mean
- 01:24:39I want to I mean they we do have
- 01:24:41treatments I don't want to say we don't
- 01:24:43we do and they are very valuable but the
- 01:24:45reality is that if you compare where we
- 01:24:47are in drug addiction treatment versus
- 01:24:49where we are on HIV I mean there's there
- 01:24:53there's a cute Gap and and yet that HIV
- 01:24:57which is a devastating disease is a a
- 01:24:59new disease and we invested the
- 01:25:02resources National mobilization to fix
- 01:25:05that disease we we're not curing it but
- 01:25:07people can live very healthy lives and
- 01:25:10die of something else even for nicotine
- 01:25:14nicotine which kills how many people in
- 01:25:16the United States what's nida's estimate
- 01:25:19of the cost of drug abuse and alcoholism
- 01:25:22it basically more than half a trillion
- 01:25:24dollar a year
- 01:25:27unbelievable I mean I I given that cost
- 01:25:30just that like we're not even talking
- 01:25:33about the human suffering involved but
- 01:25:35just the financial cost alone you would
- 01:25:37think would be enough to drive a drug
- 01:25:40company to want to cash in on all those
- 01:25:43people you wanting to alleviate that
- 01:25:46pain yeah but you have to look at the
- 01:25:48we've been talking about the fluidity of
- 01:25:50the BL brain the complexity of the brain
- 01:25:52I think what you know people want is you
- 01:25:54know just like if you had a you had a
- 01:25:57bacterial infection aha take this you'll
- 01:26:00be good in two weeks okay and ah you you
- 01:26:04have cocaine addiction oh take this
- 01:26:06you'll be cured in about a month uh it's
- 01:26:08just not going to happen that way and so
- 01:26:10I think because there's no concrete
- 01:26:14piece that someone can say you can take
- 01:26:16this and it'll take care of you it's
- 01:26:18it's difficult to fund something you you
- 01:26:20can't give me this end point right where
- 01:26:22people want and so you know the goal
- 01:26:25posts keep changing I don't think people
- 01:26:27you know people who are investing in
- 01:26:29that that bothers them but but I mean
- 01:26:31you
- 01:26:32know the brain's complexing the fluidity
- 01:26:34it's going to and you have to just
- 01:26:36recognize that we're now used to taking
- 01:26:38blood pressure medication uh cholesterol
- 01:26:40medication every day for the rest of our
- 01:26:42lives so it may be that a person who has
- 01:26:44an addiction once a treatment becomes
- 01:26:46available will do the same but that's
- 01:26:48okay we just need those I can't
- 01:26:50imagine who you know if you if you could
- 01:26:53tell any addict that I've ever met if
- 01:26:55you take this pill once a day every day
- 01:26:58for the rest of your life this horrible
- 01:27:00thing will go away I mean I can't
- 01:27:02imagine who would say no to
- 01:27:05that I mean zero time I just said
- 01:27:08exactly oh we run out of
- 01:27:10time well thank you so much this has
- 01:27:12been a fascinating discussion and you've
- 01:27:14been a fascinating and wonderful
- 01:27:16audience tonight we really appreciate
