Kind: captions Language: en medical cannabis is is going to be the big revolution in over the next 20 years if we use it properly david nutt welcome to the show good to be with you i'm really excited to talk to you today i'm super intrigued by drugs in general by the brain by the way that we can manipulate our brain chemistry through drugs and your latest book cannabis makes a pretty compelling case for all of the interesting things that marijuana can do for us and i'm curious why do you think like when i look at the stack of things that you talk about in the book that cannabis does controls may potentially help with in the human body experience it's a it's a long list why is cannabis so active well of course we discovered that in recent years because the brain makes its own molecules like cannabis it makes several of them we've identified one called a nandomni one called 2he and it turns out that those chemicals work on receptors the same receptors as thc the active ingredient in cannabis works on and and there was a mystery for 20 odd years when we the cannabis receptors were discovered no one had a clue what was going on but it turns out that the brain makes its own um cannabis molecules and it makes them in a very special way it makes them from nerve membranes so when nerves are activated they release some of the membranes into the fluid around the nerve and they get converted into these these cannabinoid substances and they usually go backwards and so they affect the nerve that's releasing the neurotransmitter so they're a very novel form of what we call feedback inhibition what is feedback inhibition right so for instance let's put it this way if you if a a nerf a nerve fires and the way in each nerve communicates one nerve to the next is not by electricity it's by chemicals they're called neurotransmitters so for instance if a nerve and most of the large proportion of the nerves in the brain actually releases a transmitter called glutamate so glutamate comes out of one nerve ending goes across the synapse hits the other nerve ending stimulates it the nerve starts to fire as it starts to fire it releases these molecules which turn into these endocannabinoids which come back across the synapse and turn off the firing so they it helps regulate like a thermostat in a housing helps regulate the functioning of that particular synapse or that whole complex of sinuses i don't know if this is connected but one of the more interesting things that i've heard you talk about with psychedelics is that part of what you discovered or has been discovered in the research is that when you take a psychedelic it's not activating areas of your brain it's actually turning off areas of your brain is that is that a similar kind of function that we're seeing here where the inhibition of something is creating this i mean i guess depending on who you are sort of euphoric feeling that marijuana can bring about or is this completely different that's a great question and the answer is it's complicated one of the real paradoxes when we discovered that psychedelics actually turned down brain activity we scratched our head and then we looked around to see what other drugs did that and interestingly the one drug that does not do that is cannabis that increases brain activity so i am uh i have used marijuana my wife is a big fan uh i'm a sort of but it feels like i'm sort of collapsing inside of myself that i can get lost in a single thought that that one thought just becomes so all-consuming and not in an unpleasant way but just that i'm i'm lost in that thought so it feels like less of my brain is active so what part of the brain is actually lighting up that gives that sort of all-consuming sensation well the answer is i don't think we know because despite the fact that cannabis has been both widely used for for many many decades and also has been a medicine in america now for 20 years there's been very few studies on cannabis brain imaging but what we think is happening uh is that at one level it is working like psychedelics but not at the metabolic level but in the circuit level so we think that the circuits are similar and what what we know happens with psychedelics and we've got less data with cannabis but what we know happens is that the the normal mechanism that basically tells your brain what to do there's a network in your brain called the default mode network and that that basically drives your current thinking and makes you well with what you are it's where your sort of sense of self is that gets switched off to some extent by cannabis and by psychedelics and uh and that switching off that basically detaches you from your normal routine daily thinking the standard we're able to upgrade works and that allows you to then think differently now in your case thinking differently means that you're getting interested in a particular topic and you get deep deep into it in other people it's different than other people the mind kind of opens and people get this sort of broader sense of being more out there more communicating you know more part of about the outside world and why there are individual variations in this is completely unknown in presence it's probably got something to do with personality with interests with um what you were doing with the moving forward do you think it has anything to do with enzymes and i'll i'll explain the question and then you can uh either shoot the theory down or let me know but uh so the first time i had no interest in trying marijuana my wife finally convinces me to give it a shot and i try it and i'm like this is the worst experience ever this sucks there is nothing interesting about this i feel like i just want to lay on the couch my head felt heavy i would be like wait we're still watching tv it was like somebody was pressing play and pause on my brain it was horrible and my wife was like you know that's interesting that you say that she was like when i first started smoking i had some kind of like sense like that but she's like it's not like that for me anymore and i remember thinking that doesn't make sense like how could it be different for you now than it was in the beginning so anyway years go by she gets me to try it again i have the same sensation this is lame not interesting years go by she gets me to try it again and that time i had a body high now that is a whole different experience which we'll get into later but that prompted me to want to try it again and so then all of a sudden because i tried it a week later it felt completely different and i was like oh my god she's right and so i was thinking of it kind of like alcohol where if i understand alcohol metabolism correctly you get to the point where you have the enzymes that can break the alcohol down so you're able to get it through your system quicker it takes more to get you that same level of intoxicated and so i was like is there something my it really feels like my body now handles it very differently if i smoke sort of with only a week in between what's happening there well that probably is it's probably not metabolism it's probably some kind of adaptive changes at the level of the receptor interesting probably and and this you raise you know again really fundamental questions which is almost unstudied often when people start smoking cannabis they do get very weird experiences and they often find very unpleasant they often get very anxious and then over time that goes away but then over time something else happens and people begin to get more sensitive to it in a different way and they get more paranoid and that's actually one reason why quite a lot of people give up smoking cannabis in their 20s and 30s because of the paranoid feelings beginning to develop and so they're almost certainly two separate processes going on there's a process where the receptors or the circuits begin to adapt so they they get less less worried in if you can use that kind of term for a circuit by the the change in brain function and that then allows you to engage with the positives of that function because you're not so concerned about the change and then over time something else happens probably in a different circuit or different neurotransmitter system which then turns on probably something like the dopamine system which then leads to paranoia so you've got to remember you know cannabis can affect pretty much every other neurotransmitter system in the brain yeah that's in fact i want to go back to that it seems to be impacting some sort of master regulatory system well one i think it would be useful your book talks a lot about seizures but you also and and um the role that cannabis can play there which is pretty extraordinary i had not heard about the connection between cannabis and seizures and my first interaction the first time i ever saw somebody smoke weed it it like put a um like my brain took it down is like there's something here because this guy was he had tremors like really bad tremors like the amount that my hands are shaking right now if you're watching youtube you'll see uh if you're just listening to this my hands are shaking a lot and you could hear it in his voice like he had that like if you're really nervous and your voice is quivering he sounded like that all the time if he smoked like literally six minutes later you can watch his trimmer stop and then he could talk normally and i was like what just happened it was at one point i actually thought he was [ __ ] with me i was like how's it possible so as walk us through a few of the things that you enumerate in the book that cannabis does so we've got seizures um weight loss like there one you've got you you talk about this in the book you've got if people smoke they tend not to gain too much weight smoke weed not not even tobacco which is a whole different thing but if they smoke weed they tend not to gain too much weight but they also don't lose too much weight and it can be used on that side that's exactly right you have that's a very good example isn't it of an adaptogen it cannabis helps it paradoxically when you get the munchies you don't get diabetes because yeah somehow things it normalizes the biological process relating to appetite all right my friend i have a big announcement my incredible and talented wife lisa is about to launch her new book radical confidence in it she has managed to perfectly capture the process of how to go from feeling lost and insecure to taking control of your life and doing amazing things despite feeling fear sometimes a lot of fear now let me tell you nobody knows lisa better than me but when i read radical confidence for the first time and heard her describe what it was like for her to go from having these big exciting dreams as a kid to then as an adult scheduling her life around the tv shows that she wanted to watch or how lonely and isolated she felt instead of pursuing her dreams it was brutal for me i would never say though that it was worth it for her to go through all of that just so that she could write something down that allows others to avoid it but i will say that at least she was able to capture the strategies that she used to break out of that rut find her voice and begin doing incredible things despite her insecurities and fears that she wasn't going to be good enough to achieve great things so while it hurts me to know the dark place that lisa went through i really am excited for people who are going through something similar right now to read this book radical confidence is an instruction manual for how to become the hero of your own life even when you're scared to death look i know better than just about anybody how easy it is to get off track in life or to just not have yet found your calling and it's even easier for people to feel so insecure and unprepared that they don't even want to pursue the things that they want but what lisa shows people in radical confidence is that the radical part is that you can accomplish extraordinary things even when you feel fear that's what radical confidence is being afraid and unsure and having a tool kit that allows you to still make massive progress pre-order your copy today because if you act now you can claim the bonuses that lisa has created for you at radicalconfidence.com they're only available if you pre-order so act now then once you've done that we'll get back to today's episode all right guys read the book and get ready to be the hero of your own life peace out when you get people that are really pro-cannabis they make it sound like a panacea and as an adaptogen that's very interesting and i don't know if there are other drugs that function in a similar vein but um is marijuana a panacea or are there limits like what's your general take medical cannabis is is going to be the big revolution in over the next 20 years if we use it properly in the same way as in the last 20 years the big revolution has been in immunotherapy but medical cannabis way way cheaper than the new immunotherapy and potentially uh as for many disorders as effective the big problem and this is particularly what it's an american and canadian problem really is is that the opportunities already almost been missed because so many people are using medical account of this but it's still illegal under federal law that until very recently you couldn't get federal funding to study the medical benefits so you've genuinely missed a huge opportunity in the states for by having this complete mismatch between what the states are doing and what the government wants you to do but hopefully at some point that will change and then we would start doing very systematic analysis on a range of different disorders and actually can i just tell you that's one of the things we're doing in britain in britain we have we hardly use medical cannabis at all because we have socialized medicine and the nhs is very is and the doctors in the united states are resistant to cannabis and we can't therefore go out and buy it like you can in a minute you know we we don't have the that facility that because we you know you have recreational cannabis in many of your states we don't have any at all so what what my charity drug science did was we set up a registry we we worked we found some cannabis suppliers we found some doctors who wanted to prescribe outside of the nhs we brought the price of medical cannabis down to be equivalent to what people would buy on the illicit market and and we've given we've set up this large database of people who are getting medical cannabis privately we've got two and a half thousand people in that database now of which half of them are using it for pain so that's one-fifth of the total number of people in the world who've had measures of pain taken on cannabis and 44 of the people who were using opioid painkillers before they went into this study have stopped using them 44 nearly half that's just absolutely transformational so one of the interesting things we've done uh in the last year again through this charity of drug science is is to evaluate different forms of cannabis for pain and we and we've compared them with other drugs like antidepressants gabapentinoids and opiates and also the simple painkiller called ibuprofen and we use the special technique called multi-criteria decision analysis which allows us to properly evaluate both the the benefits in terms of pain relief and in terms of quality of life and also the benefits in terms of safety and when we did that we discovered that the best overall uh product for pain relief was actually a combination of thc and cannabidiol and that's actually what other patients say because we have patients involved in this analysis as well this is more than opioids well much more much more twice twice as good as opioids is that though just based on the danger of opioids or is there actually a sort of close proximity to pain management as well bit of both so that combination of cbd and thc so we're looking at maybe you know 10 to 20 30 milligrams of cbd and 5 to 10 milligrams of thc that produces pain relief which is actually greater than that of opioids in in chronic pain not acute pain not not surgical pain but with people with chronic pain opiates aren't very good in chronic pain because you get tolerance and can you can you differentiate between the two types of pain at a nerve level like can could i look at a scan of some kind and say oh this is acute pain or this is chronic pain um that's not yet possible but what is clear that chronic pain when pain starts you know you break in you have your leg amputated yeah you get run over our truck your leg gets crushed right it's a lot of pain opiates good for that you cut the leg the leg gets destroyed you cut the leg off amputate what happens then eventually the pain starts to recite itself in the brain so this chronic neuropathic pain becomes a brain disorder rather than a traditional pain disorder from the nerve endings in the periphery and when it gets embedded in the brain opiates don't work particularly well because they tend to work at the level of the spinal cord but the cannabinoids work pretty well they work as pretty much as well as the antidepressants and the gabapentinoids and they're also better than um the opioids but they have quite a high side effect burden whereas cannabidiol thc is it came out higher in our schools because it's very well tolerated as well as very effective well it's really interesting so does that tie back to what you were saying at the beginning where you get this quieting of the nerve signal when you're taking in i guess it's both thc and cbd but is that the mechanism that you suspect is at work i think that's the mechanism at work for the thc we're still upset a bit of mystery why cannabidiol helps there i think it it might simply be that it makes the thc more focused in its actions so it takes away some of the unwanted effects of thc it may have an effect by itself it's almost i mean there's almost zero almost zero research on the brain effects of cannabidiol it's really interesting so you had a conversation with peter tia that i liked very much and one of the things that peter brought up that you said really resonated with you is this idea that if you're taking a drug and you have to like take it forever to keep getting the benefits that's less ideal than something that you take and it actually creates a long lasting change what peter called it changes your trait so i have these obsessive thoughts i'm having to intake marijuana to keep it at bay to make it manageable but are there things that i can do in certain circumstances like psychedelics where i might be able to completely disrupt that pattern well that's what we believe in fact we're doing a study now of cytosimin in chronic pain trying to see if we can you know as you suggest break down those repetitive thinking processes which have become over learned and so you can see pain as a thinking habit in the same way as twisting your hair or picking your nails as a motor habit yeah that study's about to start so in a couple of years we'll be able to answer your question hello my friend you know that i believe success requires you to see failure as the ultimate learning tool success requires you to be disciplined and gritty and to never ever quit on your dreams i say all of that because one thing is certain the road to achieving your goal is not smooth or linear i wish it was but it's not it's going to be bumpy sometimes scary some days you'll take two steps forward and slide 10 steps back and that's why success also requires you to know how to pull yourself out of a rut and get unstuck fast life is short you can't be messing around with your goals you've got to make progress every single day so i've pulled a class from impact theory university called how to get unstuck which you can watch for free with the link on your screen or by clicking below when you join me for that free preview of that workshop from impact theory university i'm going to teach you my strategy for how to understand exactly where you need to be going how to identify the obstacle that's blocking you and the best way to make the most progress towards that goal and keep your momentum right click that link and let's get to work all right i'll see you on the inside uh psychedelics as we talked about earlier turning things off not on do we have insight into what exactly it is that they're turning off that creates this it's like we're seeing things that we would have seen maybe as a child an infant and it's sort of bringing us back to a more primal i don't think you ever use that word but what what are we shutting off so yes it's the way the brain works is uh to create hypotheses let's take the example of vision because that's the easiest one to explain your brain is not a camera you're looking at me now but you're not your brain isn't taking photos of me what your brain is doing is analyzing the lights that's coming from from me into your eye or from your from your computer into your eye and then it's turning that those different light signatures into electrical impulses the electrical impulses are then going into your the back of your brain the visual cortex which is a large chunk of brain you know it's as big as an orange and you're going to different parts of those because different parts of your brain deal with different parts of the vision visual system and and then over over a period of multiple layers of analysis you you go from what you want the very primary electrical impulses to you start your brain start to construct multiple levels uh what it ends up being an image that you see and when you're a baby it's all buzzing and complicated and your brain isn't very good at making hypotheses because it's never made any before it hasn't met things but as you as you start to grow up you you start to make these ideas it's something out there you know there's your mother there's a chair so you might see a chair uh you know something's sticking out you know wooden thing and then you might touch it and discover it oh that's right that's a solid thing and then your brain learns oh okay what i thought was there is there and that process of gradually creating a whole series of estimates of the world and then testing them and retesting them is actually why the brain isn't the most efficient computer ever known is 10 times more efficient at computing things than and the best computers we have today because because it it's much cleverer it makes these estimates and when it's worked out what something it doesn't bother to re-update them it doesn't bother to spend energy repeating it it just knows it's there and carries on now when you take that process of building up requires interactions in the visual system probably 10 billion neurons are working to make an individual image when you give a psychedelic the neurons in the brain the visual system which connect the color center to the movement center to the darkness center to the shape center to make an image those neurons are disturbed by the psychedelic uh and i don't exactly know why they've got so many receptors for psychedelics but they do have and and and that when you disturb those neurons you can't reconstruct the full image so what you see as these christmas tree lights is what we call elemental hallucinations under psychedelics you're actually seeing the very early first stage processes of visual reconstruction when the impulses from the eye first get into the visual cortex we know from physiological experiments in in frogs for instance that the way the brain works is to construct simple shapes squares circles spider webs simple colors and it puts them together so one of the most remarkable things about psych psychedelics are putting you back to seeing what what you used to see when you're a very a very young baby before your brain learnt to make these simple images into much more complicated ones so i find that really kind of appealing because it's you obviously you can't remember singing as children because you didn't have the memory system but now you can you can infer what what it's like to start seeing things afresh that's really intriguing so i've never done well so i've micro dose psilocybin but always micro so i've never had any hallucinations or anything but my understanding from hearing people talk about it is that they will see and sometimes interact with like a dragon or a flower comes to life and so it isn't at least as they've relayed it to me it isn't just like sort of shapes and things like that it does seem like they're putting something on it um and i don't know how much you get into you know the collective unconscious or you know how many like are those things that we just are carrying with us or it's an overlay there's some sort of reversion to um what you how you would see as an infant just getting sight for the first time but there's also this sort of layer of abstract meaning that's laid over it like what's that interaction like a really important question so yes so there's much more to a star academic trip than just seeing christmas tree lights i mean they're pleasant but there's but people often see much much more complicated kinds of imagery and also have a low whole range of other experiences like that their body might dissolve and they might go to heaven and you know go into another universe or different dimensions we don't understand why some people have different kinds of um of content i think we do understand that that the change from normal consciousness to psychedelic consciousness does involve perturbations across the whole of the brain our imaging studies particularly with lsd show that the powerful really complicated rich dreamlike hallucinations visual hallucinations and often beliefs that people have under lsd when their eyes closed they're due to the brain becoming hyper connected so normally the visual system is just embedded in the visual system but under psychedelics because you break down the default mode network the visual system can then connect everywhere in the brain and that contributes to things like synaesthesia where you know you might you know see sounds or it's already connected right it's not like the connections happen during the trip but there's the inhibition is shut down and so now they can actually communicate exactly the whole point human brain development well why is that why do we have a brain after you know several billion years of evolution is it's come from a food targeting process it wants to get out get you out there and get food and of course the second main role of the brain is to find mates so you can reproduce okay uh now everything else on top of that is kind of incidental because the brain you know brain really just wants to make sure there's another brain in the next baby so you get big enough to have reproduce have a baby right so the brain has become really efficient at doing the things it needs to do and and that's the problem the default mode in in many ways creates that efficiency but it also because it distorts and it limits the capacity of for many people to do other things i mean there are people who don't there are people you know who do have spontaneous visions there are artists who see the world in a very different way and and can create you know completely new ways of thinking but for most of us the brains are pretty boring it creates a pretty warm war because that's the most efficient thing to do just do the same old thing and then pass it on to the next generation and psychedelics break down those habitual processes which limit our vision and limit our vision in the sense of opportunity rather than just seeing things that's a really intriguing way to think about psychedelics that it's one the connectivity and i saw an image that you um put up where it's like here's what you know the normal level of connection or communication maybe is a better way to say it the normal level of communication and then here and it was like all these extra lines of communication this is what it looks like during psychedelics and as somebody who and this is your you're really intriguing me around trying psychedelics because i consider myself just obsessed with hyper efficiency and something has changed in me as i've gotten older and i do wonder if in getting more and more and more efficient if i'm not narrowing something wonderful out of existence and so yeah that's that's a very intriguing idea that was originally why i microdosed was i had heard that microdosing makes you feel more creative and so i just i wanted to try anything that was going to make me feel more creative tried it nothing tried marijuana nothing they don't make me feel more creative marijuana does shut down my default mode network i think that's a perfect way of explaining it but i don't feel increased connections now the only thing that i do feel like does that is meditation i refer to that state as calm and creative where i feel like weird areas of my brain that don't normally talk start talking well exactly i mean a week after we published our first the first paper on the altered state of silence timing consciousness a group from yale a jed brewers group who you know wrote to us and said look that's just what happens when people go into transcendental meditation they're so interesting we thought wow that is truly remarkable the difference is of course you know it's quite hard you know you've got to get a lot of practice to switch off that to get into a transcendental state with meditation but if you do you're actually pretty close to that uh the same status on psychedelics you're disabling and that's what you're trying to do meditation you're trying to disable that inner mind the devil mode network you're trying to disable it to allow you to think differently because it doesn't want you to think differently it just wants you to go to work and get up and up you know i mean and you've got you've got to fight with it to disable it with meditation and psychedelics do it a bit more easily it's really really interesting talk to me about safety so you rank drugs by order of safety anybody listening to this conversation could probably um take away that you know we don't think there's any danger in all of this is there danger in this is there danger in marijuana is there danger in psychedelics um yeah how worried should people be well there's danger in all drugs when we look at the deaths from drugs in your country in my country tobacco cigarettes away the top of the list followed by alcohol and then then followed by opiates and at the very bottom of the list of psychedelics that takes into account like the totality so i would in fact i'm curious if you had the same number of people smoking the same number of cigarettes the same number of people smoking marijuana the same number of people doing opiates like then does it does it still come out the same or are there some that are just way more deadly like is marijuana 10 times more deadly it's just way fewer people smoke it no no no it was the other way around the fentanyl is ten times more deadly in terms of harm from the drug to the user fentanyl other strongholds like heroin crystal meth they are the drugs that kill the individual uh lower down alcohol tobacco and the very bottom drugs like magic mushrooms like lsd like mdma they have much lower rates of harm to the individual now cannabis is a bit between the two cannabis is less harmful than tobacco but more harmful than psychedelics and and that's really because people tend to use cannabis much more than use psychedelics most people don't use psychedelics more than a few times in their life and if you try to use it a lot you get tolerant so it doesn't work and so it's it's no point whereas a lot of people who use cannabis do use it maybe for 10 or 20 or 30 years and the more you use a drug the more chance there is of it causing harm and what is the mechanism of harm for cannabis so very few deaths okay i mean older men with cardiovascular heart disease hypertension it does put your blood pressure up you know and again you know you can see that with the red eye so there are people you know occasionally getting very very stoned in their heart they have a heart attack i mean they might have had the heart attack anyway but it's not good for people with heart disease um and that that's the main harm but then the other harms in terms of dying in terms of the other harm says dependence if you get dependent well it can be really quite upsetting and quite disabling to your life so over the last 10 years we've done an enormous imaging study we've studied over a hundred people with opiate and cocaine addiction and alcohol addiction and compared their brains with people who haven't had such an addiction and before we started my researchers said well what we're going to do about cannabis because everyone's known what happens about cannabis and i said well what we're going to do is we're going to divide the group the drug using group up into those who use cannabis and those who don't so you get rid of cannabis users you're half the number and i said i'm going to bet you that the cannabis users have better brains than the non-cannabis users and i was right interesting cannabis is why did you bet that well because cannabis is an adaptogen cannabis is an anti-convulsant cannabis is possibly neuroprotective against brain trauma i bet it i bet that because i it just seemed to me that from what i knew about cannabis ten years ago it was likely to be probably neuro protective and what was the the mechanic that you used to judge that how did we say it's healthier rainbow what metric brain volume right so alcoholics shrink their the brain you know alcoholics brain shrinks as a result of the toxicity of alcohol and cannabis protects against them but why then is weed known for like oh you're you forget it's bad for your memory is that just a cliche that isn't true or is there something there well of course it's there's truth in that if you're stoned all the time you know you you're intoxicated same as alcohol you're intoxicated all the time it will impair memory it will impact but it doesn't produce any enduring damage to the brain like alcohol and alcohol is the only brain the only drug you can say on an x-ray look that's for a ct scan or an mri scan that's that's a damaged brain even even in a cocaine in crystal don't damage the brain the same way alcohol does whoa this recent study at a harvard school of public health they looked at people who drink alcohol and with or without cannabis and they look at liver cirrhosis the people who use both have much much lower rates of cirrhosis of the liver than the people who just use alcohol and they're now doing trials it may be that kind of cannabis can protect or treat alcoholic liver cirrhosis it may be an adaptogen in the liver okay that's uh this is where it starts to just seem too good to be true so if and i know that it hasn't been studied so you're going to be guessing here but when we think about it being an adaptogen in the liver what i know about cirrhosis and maybe i'm just wrong but that it's scarring so i'm curious as to what your guess would be on the so we understand the in inhibition where um cannabis is going to trigger the release of a signaling molecule that's going to tell the nerve to stop firing but if we're punishing our liver by drinking too much alcohol we're running so much toxins through it that it begins to scar what mechanism would the cannabis be using to protect that's so confusing cirrhosis is caused by the production of what i call free radicals from the breakdown of alcohol and cannabis particularly cannabidiol soaks up free radicals it's anti-inflammatory wow man okay so we you said at the top of the thing that we should have been looking at this stuff all along and that we've missed a lot of insights make some predictions for me knowing full well that you're a scientist and so these are hypotheses and you're more than happy to see them disproven but where do you think like as we spend let's say the next decade really looking at this stuff what are we going to find well we're going to find that medical cannabis is the preferred treatment for chronic pain for quite a few forms of anxiety for people whose ptsd hasn't been remedied by mdma or psychedelics for people with chronic inflammatory gut disease like crohn's disease other colitis a lot of people are using it and getting benefits there you're probably going to find it's also got enormous utility in some cancers one of the most horrible aspects of the of these bans on cannabis was that there was a systematic attempt to stop the publication of papers showing that cannabis had anti-cancer abilities back in 1978 to the most senior lung physician in america which had a study which showed that cannabis smoking had less lung cancer than the normal population what i was literally going to ask you about um lung cancer but didn't you say that it it seems to have i mean if i'm inferring correctly from what you said that it would be protective not curative but protective in some way and that you if you are smoking cannabis you fall into a cohort of people who are less likely could be correlation but are less likely to have lung cancer is that true yeah that was that was that was the that was the epidemiological data it's never been trialled as a protective thing but what we say or what i say in britain in britain most people who smoke cannabis smoke it with tobacco i say don't do that do what the americans do and smoke it meat but it's it's harder for us to get neat cannabis here because it's illegal so we yeah so but it it's to my mind it's none of this is surprising given what we know subsequently we didn't know then but what we know now about the ability of of cannabidiol etc to have this these anti-inflammatory and and possibly anti-cancer properties it needs to be tested we need to be doing lots of studies but we're not because it's a plant product and it doesn't fit into the current model of pharmaceutical drug development wow well david you've certainly piqued my curiosity on this and make me want to learn even more about it your book was phenomenal where can people find out more about you about your non-profit yeah what should they do to engage so the best thing is to just go onto the website and look up drugscience.org dot uk and then you'll see my charity you'll see all the publications there's there's lots of publications about cannabis all i've talked about now in terms of my research is on there for free there's slight sets there's podcasts of me talking about this and yeah and then become a follower because drug science is you know we we tell the truth about drugs and the very very few other places you can get back down the truth amazing man thank you so much for joining me today this was a lot of fun guys check it out this is really intriguing our brains are neurochemical processing plants so once you understand that you're dealing with chemistry all the time uh not that i'm a huge proponent of exogenous chemicals but there might be enough research coming out in the near future to warrant some further exploration so check it out speaking of further exploration if you haven't already be sure to subscribe and until next time my friends be legendary take care peace
