How does marijuana affect your brain?

Marijuana Weed Pot Kush Herb Grass? I don’t know. Ganja The devil’s lettuce Cannibis or THC? Mary Jane Loud I know there’s some CBD things now that… I don’t know what it stands for, but That’s all I can think of. Blunt Bongs That’s not…that’s not weed. Whatever name you give it, cannabis is the most commonly used “illicit” drug in the United States. And it has a pretty prevalent place in our
society, popping up in our media and on the news. Marijuana has long been considered a gateway drug gateway drug gateway drug Marijuana is a dangerous gateway drug. leading to the use of other, more addictive,
and more dangerous substances. But what does marijuana actually do to to
the human brain? …and body? And is it as dangerous as D.A.R.E. always
led us to believe? This is drugs. This is your brain on drugs. Any questions? Well, marijuana has been legalized in several
states. And it’s legal for medical use in several
others. So it’s becoming more mainstream. In fact, it’s legal right here in California. So we went to a local cannabis dispensary
to talk to some experts in the field. So my name is Shelby. I am the assistant marketing director here
at Torrey Holistics. Here at Torrey Holistics, we really try to
do a lot of education because that’s ultimately where we are going to break down the stigma
where people are going to realize the medicinal benefits of cannabis. Torrey Holistics opened as a medical dispensary
in 2015. We were the first in the state to get our
recreational retail license, but we still serve medical and recreational alike. Marijuana use in the U.S. has a pretty interesting
history. Early white colonists brought cannabis to
North America to cultivate as hemp, which was used for making rope, clothing, and paper
products. During the 1800s, it became popular as a medicinal
treatment, and “hashish houses” flourished. Until 1906 when the Food and Drug Act required
labels on anything containing cannabis. Then, as Mexican immigrants began arriving
in the U.S. following the Mexican Civil War, they brought recreational marijuana with them. Racist anti-immigration sentiment rapidly
led to fear of the “Marijuana Menace”. In the 1930’s, a string of very dubious
studies linked marijuana use to violence and crime. And states began to outlaw the narcotic. When Harry Anslinger, the Chief of the Federal
Bureau of Narcotics was appointed, they were going through a budget cut because of the
Great Depression. So to keep his title and keep funding for
the department, they actually kind of created this whole scare around cannabis. He started referring to it as “marijuana”
because he knew that everybody was already consuming cannabis. It was in tinctures, you could buy at a local
pharmacy. And so the senators who were voting on this
prohibition bill didn’t realize that marijuana was the same thing as cannabis. So they effectively voted to ban the very
substance that they were using for their own medical needs. Following the release of the famous film “Reefer
Madness” in 1936, the federal government passed the Marijuana Tax Act, effectively
outlawing cannabis except in specific medical and industrial cases. For decades, despite new and better research
indicating that marijuana isn’t associated with violent crime and debauchery, marijuana
use was increasingly restricted. And the punishments for its possession and
use became more and more harsh. Anslinger first pushed it as, like, you know,
like you’re going to be very lustful and you’re going to do crazy things, it’s a gateway drug. And then he actually changed his rhetoric
later in the century to be, like, cannabis as a lazy stoner drug. Like, you don’t get anything done, you’re
not contributing to society at all. This eventually led to all kinds of government
policies, like mandatory minimum sentences, a three-strikes policy, and President George
Bush’s War on Drugs. These have had lasting and damaging effects
on many U.S. citizens and the public’s perception of marijuana. You can learn more about the history of these
laws and their effects on our country’s citizens by checking out the links in the
description below. But then in 1996, that started to change. Medical marijuana was legalized in the state
of California. And now, almost twenty years later, cannabis
has a pretty prevalent place in our society. Public perceptions and acceptance of cannabis
has definitely improved in the last several years. Especially in light of the opioid epidemic,
people are much more receptive to a lot of the research and findings coming out. So it might seem kind of weird that we actually
don’t know very much about the risks or benefits of marijuana. See, even though it’s becoming legal in
more and more states for recreational and medical use, cannabis is still outlawed by
the federal government, so it’s heavily regulated and restricted. That means that it’s difficult for scientists
and doctors to get marijuana to actually use in their research. And without that research, it can be hard
to say much about the possible dangers or benefits of using the drug. So what do we know? When you smoke a joint and get that high feeling,
what’s happening in your brain? Even that’s not so simple. Cannabis has two major chemical components. Delta-9-tetrahydrocannabinol, or THC, and cannabidiol, or CBD. Plus smaller amounts of a whole bunch of other
cannabinoid compounds. These molecules act on what’s called the
endocannabinoid system in the brain by binding to cannabinoid 1 and 2 receptors. These receptors were actually named after
cannabis, because they were identified by scientists trying to understand how the drug
works. Both kinds of receptors are found throughout
the body, but CB1 receptors are the most common in the brain, found at the end terminals of
neurons. The brain produces endocannabinoid compounds,
which bind to and activate CB1 receptors. Cannabinoid receptors are g-protein-coupled
receptors, so when they’re activated, it kicks off a cascade inside the cell that has
some effect downstream. In this case, that means modulating the signaling
at the synapse. The molecular biology of this is actually
really really complicated, but in general, activating CB1 receptors has an inhibitory
effect on the release of a variety of neurotransmitters including dopamine, GABA, glutamate, noradrenaline,
serotonin, and acetylcholine. Our best understanding of the endocannabinoid
system is that it plays an important role in regulating other systems in the brain and
throughout the body. In the brain, endocannabinoid signaling plays
a role in memory, cognition, pain perception, and motor movements. THC is considered a psychoactive compound,
meaning that it affects perception, cognition, or behavior. It binds to CB1 receptors, activating the
endocannabinoid system, and inducing the feelings of relaxation and euphoria that are commonly
associated with cannabis use. As well as impairments in spatial and verbal
memory. Your license, where is your license? My license. It’s on the bumper man, right back there,
man. No, I mean your driver’s license. Oh. Oh yeah, yeah, I’ve got my driver’s license,
man. Users of marijuana often report enhanced introspection,
and sometimes feelings of anxiety or paranoia. Cannabis use can also lead to “the munchies”. Feeling like you’re hungry. Thought to be a result of the way THC is processed
by the liver. CBD, on the other hand, is not a psychoactive
compound. It has the exact same chemical formula as
THC, but with a slightly different chemical structure. This means that it binds to the endocannabinoid
system differently, and doesn’t induce those psychoactive effects. But it’s being explored for treating a variety
of conditions, and is believed to be anti-inflammatory, like ibuprofen. Most notably, it’s used to help prevent
seizures in very severe types of epilepsy. And it’s being explored for use in treating
migraines and anxiety. Speaking anecdotally, I have friends who swear
by CBD for treating their migraines. So CBD has become more popular in research. And it’s showing that it’s a very powerful
anylgesic, very powerful anti-inflammatory agent, and you don’t need to experience any
psychoactivity with it. So now you can consume cannabis without that
psychoactivity that some people are kind of put off by. You can have the medicinal benefits alone. One thing I always like to say everywhere
is that if you ever find yourself too high, say you took an edible that you’re just feeling
overwhelmed with, have some CBD on-hand. CBD will bring you down from that high. The products that are available for medical
and recreational use contain different varieties of cannabis that have different effects. Some have higher levels of THC or CBD, and
different “strains” are reported to have different psychoactive effects. Like how people say that indica is “relaxing”
while sativa is “stimulating”. The difference between different strains like
indica and sativa involves something called the “entourage effect”, which we use very affectionately in this industry. It has to do with the over 113 different cannabinoids
and terpenes in the cannabis plant. They play on each other in very unique ways. If you think about how many different sorts
of combinations those cannabinoids have, all of these different regulatory compounds are working with each other to create a specific effect. How long the sensation lasts depends mostly
on how the cannabis is consumed. If it’s smoked, it usually takes under three
hours for the sensations to fade. But oral or edible doses can last much longer,
with some of the effects lasting up to 24 hours. The research on the therapeutic benefits of
cannabis use are so far pretty optimistic. Though the studies are still plagued by small
group sizes and restrictions on marijuana use. The long-term effects and risks of cannabis
use also depend on how it’s used. Some risks are obvious. Like if you smoke cannabis, you’re at an
increased risk of problems like chronic cough, bronchitis, a weakened immune system, and
lung cancer. Unlike a number of other drugs, like alcohol
or opioids, cannabis is not physically addictive. That means that if you stop smoking weed cold
turkey, you might feel irritable, anxious, and have trouble sleeping, but it won’t
make you sick. Or…kill you. It’s also thought to be pretty much impossible
to fatally overdose on cannabis. Last year, the National Institute on Alcohol
Abuse and Alcoholism stated that 90,000 people died from alcohol-related causes. Whereas, with cannabis, there’s never been
a reported incident of an overdose. So yes, it’s much safer in that sense. Consuming an very large amount can lead to
extremely unpleasant consequences, like psychotic episodes, but it won’t directly cause death. But, that doesn’t mean that using marijuana
doesn’t come with other kinds of risks. Or that using marijuana can’t have negative
effects on other aspects of your life, like any kind of drug or addiction. Using marijuana during pregnancy is believed
to carry risks like a low birth weight and possibly other developmental problems. Though it’s difficult to say if these
effects are definitely a result of marijuana use or other external factors. If a person starts using marijuana as a teenager,
before their brain has finished growing and developing, it can have long-term effects
on cognition and memory. Researchers have done small studies using
MRI scans to look at brain structure in adults in their 20’s with people who are diagnosed
with a cannabis use disorder… basically meaning that they use a lot of weed,
and it has negative effects on their lives… and people who don’t use cannabis at all,
and found that teenagers who smoked pot daily had abnormally-shaped hippocampi and did worse
on long-term memory tasks compared to non-users. Some research has found that heavy cannabis
use starting during adolescence can have long-term effects on dopamine signaling in the brain. Dopamine is a chemical that plays important
roles in reward and motivation as well as movement control. Scientists think that this is likely due to
heavy marijuana use interrupting normal brain development, resulting in problems with the
wiring and leading to problems down the line. And in general, people who use a lot of weed
have issues with verbal memory and cognitive tasks. Pretty much all of this research has been
done in people who use a lot of cannabis. Like, every single day, for extended periods
of time. So far, we don’t know much about the possible
risks of just occasional usage, like in social settings or on the odd weekend. Our view of cannabis use at Torrey Holistics
is that moderation is key. With anything. You drink too much coffee, you’re going to
get a stomach ache. If you use too much cannabis, you could have
memory impairment. But it all comes down to just consuming responsibly. In places where marijuana is legal, it’s
generally pretty easy to access. There are storefront dispensaries where you
can talk to “bud tenders” and shop for your favorite varieties. Or online sites that allow you to order products
for delivery to your front door. But even where it’s legal, there are some
restrictions. It’s highly taxed, for one thing, and you
must be over 21 to purchase it recreationally, or over 18 to get a medical marijuana card. Cannabis in California, at least, is more
regulated than the food we’re eating. If it’s grown on a farm, maybe a mile down
the street from another farm that uses pesticides, the labs will pick up on that and it won’t
be able to be sold. So the cannabis you’re consuming, as long
as it’s from a legal, licensed dispensary, is very very safe. And while some surveys indicate that more
than half of all Americans have tried cannabis at some point in their lives, around 163 million people, only 4 million people would classify as having
a cannabis use disorder, a rate of about 3%. In contrast, about 5-6% of Americans who try
alcohol during their lifetime will become addicted. This could be because it’s just generally
much easier to access alcohol than it is to get weed. And we might see those numbers changing if
marijuana continues to become more mainstream in the U.S. And remember how marijuana is considered a
“gateway drug”? While it’s true that marijuana users are
more likely to abuse alcohol and nicotine than non-users, the majority of people who
use marijuana will never go on to use “harder” substances, like opiods. And even when marijuana users do use harder
drugs, it’s at the same rate as people who use other already-legal drugs, like alcohol
and nicotine. So it’s not an effect of cannabis, so much
as it’s an effect of any drug that affects the reward systems of the brain. There’s a misconception that cannabis is a
gateway drug. And they’re finding now that it’s actually
an exit drug. It can be very helpful, actually, in people
struggling with addictions. I see the cannabis industry fulfilling the
need for alternative forms of pain management. With the opioid epidemic, I think that a lot
of people are seeking alternative forms of relief. And they’re finding that with cannabis. Ultimately, we know that cannabis is a very
complicated plant with complex chemical components. And we don’t fully understand its effects
on the human brain or the long-term risks or benefits of its use. Scientists are hard at working on studying
this topic, trying to better understand the chemistry and neuroscience of cannabis as
it continues to be legalized in more states and becomes more popular nationwide. I’m so excited about the research coming out. Like I was saying, there’s so much to be done. Over 113 different cannabinoids that we’ve
only just touched on. So I think that the findings are just going
to continue to show the medicinal qualities of cannabis. Because it’s still federally outlawed, there
are a lot of complicating factors in its use and study. Like it might be legal to use cannabis in
your state, but you could still lose your job if your employer has a zero-tolerance
policy. One issue that I think about a lot is the
fact that we don’t really have the marijuana equivalent of a breathalyzer to quickly determine if someone is currently under the influence of cannabis or not. That means that unless a police officer actually
sees a person using weed, it’s really difficult to know if someone is committing a DUI. Because a person might test positive for cannabis
even many hours and days after its use. At any rate, it seems likely that marijuana
is at least as “okay” as any other currently legal substance available to the public. That whole “reefer madness” thing was
just propaganda. We must work untiringly so that our children
are obliged to learn the truth. Because it is only through knowledge that
we can safely protect them. So if you live in a place where marijuana
has been legalized, enjoy responsibly. Do you have strong feelings about marijuana
legalization or its use? What concerns do you have as it becomes more
prevalent in our society? Or what benefits do you think it might offer? Let us know in the comments below! Thanks for watching this episode of Neuro
Transmissions and a huge thank you to Shelby and Dr. Beth at Torrey Holistics for their
help with this video. Until our next transmission, I’m Alie Astrocyte. Over and out.

  1. Unfortunately, YouTube says this video is not suitable for advertisers (despite manual review). We get it. Cannabis is a controversial topic. However, we think that content like this is important and we will continue to make it, even when it isn't considered ad-friendly. If you like what we do and are interested in supporting us in other ways, consider checking out our Patreon:

  2. I like that you’ve ephasised the adverse effects for the adolescents. I don’t really get why you’ve summarised the drug at the end as harmless. It’s pretty much not harmless considering what is does to rhe PFC of youth (and thus adults too I’d guess)

  3. Mental Health with Dr Elliott

    Really good and objective video. There is so much misinformation and misunderstanding about recreational and "medicinal" use and about the difference between the types of cannabinoids.

  4. I have strong feelings towards the legalization of Cannabis in Germany. A significant portion of my friends are regular consumers, and only one of them is a f**k up (most of them are software engineers). I would like to consume once in a while but my entire field of work is zero tolerant towards it, while with alcohol I just wait a day and I'm for for duty.

  5. The low birth weight study is a perfect example of an inherently biased study that was looking for a relationship in order to hastily establish a causal link where there is only correlation; the standard of academic science. As for the study of brain 'malformation,' what's missing is the point that apparent brain shrinkage, as counter intuitive as this sounds, is not necessarily evidence of harm, but is in fact a medicinal result of several psychoactive substances, effectively pruning, reconnecting, optimizing brain structure, reported as beneficial by countless testimonies. When you look in-depth to both sides of any story, one always feels more natural.
    Those who are drawn to drugs usually are deficient in some way, as shown in "The Rat Park Addiction Study" as well as many others, mainly lack of nutrient variety which is exacerbated by toxins. Drugs of all kinds are always a short term fix, then again, the hard line between a food and a drug is… Wherever you've placed it. Everything is 'psycho-active' to a degree.

  6. I'm surprised you didn't take up the long term effects of marijuana on the callosal microstructural organization and it's risk correlating with Schizophrenia even if small. I hate the apologetic tone always claiming only heavy usage being the only contributing factor to disorders (seeing the correlation in European psychwards where it's harder to acquire and not used as intensely). Just like alcohol, if there is profit in it's selling, not caring about patrons health and wellbeing is expected, you can claim education and moderation is you're priority but keeping the business up is second to none!

  7. Agree that marijuana is relatively safer than alcohol, but it is definitely a gateway drug. This is 100% based on my personal experience. I moved to LSD after experimenting with marijuana and only because marijuana made me feel like I want to see what's next.

  8. DrewPeacock69 TrippyDrew69

    The gateway drug argument is only an argument because it is illegal. Most weed dealers also deal harder drugs that are more expensive, they want to make as much money as possible, when someone comes to pick up some weed you offer them something harder in the hope they will take up your offer.

  9. Raúl Del Brío San Román

    Everything we get into our body is going to have both direct and synergistic effects in our chemistry and health, being some of those effects beneficial and hazardous too. Even choosing our food habits have direct negative and positive effects, and it's information and intelligence what should influence our decisions.

    Incendiary speeches, no matter if they're restrictions or freedom ones, use to be about feelings more than about actual information and research. As always, a meditated consideration at the balance between benefits and hazards is key, as well as prudence and moderation with any voluntary "risk" that increases the numbers against you (riding a motorcycle, choosing the stairs instead of the elevator, and consuming any recreational or functional drug (alcohol, caffeine, THC, nicotine, and so on).

    I guess it has no point to live a long life whereas staying always on the safe side. If we would do that, no human would ever walked on the moon or launched itself in some crazy doomed crusade of knowledge taking the ship into the unknown.

  10. We have the equivalent of a breathalyser for cannabis and cocaine in UK. I smoke daily but can't comprehend how anyone could feel safe driving under the influence of it.

  11. I'd seriously like better research of weed's effect on the brain. It's what gets me paranoid when I'm too high. I'm a maths and CS student, I've been smoking a lot for the past 10 years, I'm always questioning how much weed is affecting my cognition.

  12. The paranoia comes from the threat of the legal system or authority. Without this threat and the fact long time smoking people do not get this reaction. That's seems evidence enough it's not a real symptom of cannabis but of the prohibition. You get the same reaction when doing anything that has similar sanctions.This needs to be studied a lot more but it's fairly clear.

  13. 15:00 Sorry you are wrong. I have enjoyed cannabis my whole life. From teens to old and broken. Entirely different use reasons and patterns. I have tried nearly every drug at some time in my life. Weed is always easier to get than alcohol. Cocaine is sometimes easier to get than a beer. You don't even have to leave your house. Prohibition and street dealers make the access to weed much easier than getting a beer for a teen. You may not live the life style of a weed smoker and one day say I want t to smoke a joint and not be able to find any. That's only because you don't know where the dealer is not because it's hard to get or access is hard.

  14. My main worry about legalisation is an increase in second-hand-smoke problems. Both my SO and I have pretty bad (and somewhat weird) physiological reactions to inhaling cannabis smoke: it causes her to immediately and unrecoverably lose her balance for a few minutes, and it makes me … fighty, is the way I generally describe it (which is weird because I'm normally really laid back and it's not AFAIK a common effect of THC). So I worry about irresponsible consumers just blasting out smoke clouds in the middle of the street, like tobacco users sometimes do, and screwing up our days.

    Responsible use, I have no problem with, obviously. Do what you want unless you're harming others 🙂 (In case it's not clear, I'm pro legalisation, though I'd like use regulated in line with tobacco: no use in contained public spaces, go to the smoking place if you want to smoke, etc.)

  15. It's a good thing weed is getting more and more accessible legally because prohibition just doesn't work. At best the government just looses potential benefits from taxes and at worst it puts money in criminal organizations' pockets.

    Easy example: here in France, it's illegal. And I definitely don't know ANYONE who smokes weed and it's IMPOSSIBLE to buy it almost everyhere *wink wink*

  16. Sadly weed isn't legal in most countries in europe but it's spreading. Being an irregular recreational user myself, I am really willing to spend a few bucks more just to know that it's safe and legal. But as you said, using it responsibly is key to this – as it's pretty much for everything in life 🙂

  17. Canadian medicinal cannabis patient here, love the effort made to be as fair as possible and clear the misconceptions!
    Also loved the Tom Scott guest video, so youve got another subscriber!

  18. Few years ago someone are sent to jail because he planting canabis in his house to treat his wife that have intestinal desease , and her health condition are actually improve but he get caught by police then sent to jail, his wife died only 2 month after that, i am curently a college student majoring in biotechnology i hope one day my research can change this law and at least my country would legalize canabis for medical use

  19. Thank you for this video. I've been diagnosed with fibromyalgia, anxiety, and a couple other minor CNS issues, and have been using cannabis nearly daily for a couple years now after weening myself off of about twelve different medications. I very much look forward to to one day being federally legal if only for the amount of research that will then be possible. To be honest, I do worry about the long term side effects, but not as much as those that came with the previous prescriptions that I was on.

  20. Some thoughts from Michigan where marijuana was legalized in the last election. In this weird transition period it currently legal to possess marijuana, to grow marijuana for personal use, and to use marijuana in a private space. Meanwhile it is illegal to buy or sell marijuana because the tax regulations are not in place outside of prescription marijuana.

    So, I can grow up to 12 plants for personal use in a private grow room, and consume it in my own home… but I can't legally buy the seeds I need to grow it, nor just buy someone else's marijuana to use. It's a weird legal limbo where it's legal to have and use, but the means of acquiring it are all illegal.

    I've started using marijuana to treat an undiagnosed condition that includes fibromyalgia. And one of my recent concerns was where the state of the laws leaves travelers. My condition has left me mostly home-bound. But I can foresee a possibility of needing to travel for work later this year. The stresses of traveling WILL cause me additional pain as well as flare my other symptoms. In other words, I'm going to need my weed.

    But while marijuana is held as a class 1 narcotic by the Federal government, transporting marijuana between states – even states that are in agreement as to the legal state of it – may constitute something akin to a Rico violation. Boarding a plane with the substance I will shortly need to recover from the act of boarding a plane is… Another limbo.

    Legal where you take off. Legal where you land.
    Illegal to transport between places?
    Honestly, at this point… I'm not actually sure. And, who can blame me?

  21. I'm from the Netherlands, once a pioneer in drug laws. Cannabis has a weird legal status in our country. It isn't technically legal; but politicians, police and justice have agreed when someone uses it not to arrest them(within a certain range). This is called "tolerated", or "gedoogd" in dutch. However, production is illegal(but 2 plants for own usage is tolerated, selling not tolerated). Weed stores are tolerated with strict rules. That's kind of strange. My concern is the recent trend of THC increase and CBD decrease in cannabis(source(dutch): The amount of THC in weed has more than doubled since the 90s(dutch weed: average 1994-1997: 8.5-8.9%, 2017: 16.9%, imported weed 2017: 6.9%), and there are very low levels of CBD in dutch weed(nederwiet). Because production is illegal and thus not regulated so the user does not know what he/she uses, and has to trust the seller. It should be noted that I am a bit biased because I had friends who were abusing drugs. Great video, thank you very much.

  22. I like how this shows both sides of the story, not just "it was all just propaganda it's harmless" or "it does thingies to you brain so that's BAD".

  23. I still elect to stay away, but there do seem to be beneficial parts of it. Once they figure out how to isolate the beneficial aspects (CDB for example) and greatly reduce as many draw backs as possible, the potential will increase significantly

  24. Having tried CBD for arthritis pain, my biggest concerns are:
    –that cannabis is overhyped and won't provide the sort of pain relief people expect
    –that a lack of research and regulation means that medicinal cannabis isn't as safe or effective as it could be

  25. jsndvgxkowvfks ahjdnsbjs

    I'm as pro-marijuana as most rational people, but it should still be reiterated: it's not smart to smoke and drive. Leaving aside the whole divided attention aspect if you're physically smoking while driving; there's still the fact that cannabis is psychoactive and no one should be operating a thousand-pound death machine while impaired.

    You would think this wouldn't need to be mentioned, but I've watched people sitting in the driver seat fiddling with bowls at a stoplight; packing and then smoking them. Multiple times. Always younger adults in my experience.

  26. 5:19 I keep hearing about scientists not being to do further research on marijuana because it is federally banned. Can't they just movie to a state where it's fully legal and do their research there? I know state universities get federal funding and might lose it if such research is done. But can't they move to private universities like Sanford and simply do the research there?

  27. I am athonished by the quality of your videos. I really enjoyed your style and the way you have set the topic! Scientific, unbiased, cultural. Keep going like this!

  28. Marajuana Fixes so much problems with the body like chronic pain plus cancer curing abilites plus is you have muscle spasms it works so perfectly your just happy person with no worries but have alot of munchies 💯

  29. When you emphasize (e.g. "What DO we know?"; DON'T, 'ACTUALLY) certain words, you look to the left. When you think of listing/enumerating or categorising/structuring (also chronologically) you tend to look to the right. Did you learn this or is it just a normal tendency of you when you report/describe or especially explain things? Or does your brain stores those mmories with different concepts in different parts of your brain? Thinking of it: You could do a video on not only how we stores memories (I think you already did that) but also where we might store them. Is that a good idea for a video?

  30. Really enjoyed this video although from the articles I have read recently there is nothing that points to smoking cannabis has an increase of lung cancer in fact I have read the opposite no I'm not that person that believes cannabis cures everything but I definitely don't think from what I've read and research that it causes any form of cancer but in fact the opposite

  31. Something to add… I have found that different strains of MJ affect different people differently. I have a chronic, debilitating, connective tissue disease. Some pot helps my pain, while other strains actually make me able to feel the pain more acutely. So now I don't use any at all because when it's bad, it's really bad.

  32. One of the reasons why I’m personally against the use of marijuana is due to some of the mental effects that can be caused by a bad high. I personally suffer from the sensation of depersonalization due to my anxiety disorder. This sensation is essentially not feeling alive/in a terrifying dream like state. This is one of the worst feelings I’ve ever experienced and the panic attacks that come from it are horrible. A lot of individuals who suffer from DPDR developed the disorder after a bad high from smoking weed. The DPDR sensation is widely experienced (in small amounts) yet still very unknown. The long lasting experience of this disorder is not something I would wish on my worst enemy and I personally could never understand why someone would take that risk just for a high.

  33. I first smoked when I was 12. I used to steal money from offering plate at church to buy weed. I'm 56 now and I grow my own. God I love weed. 🙏🏽🤗🙏🏽🤗🙏🏽🤗🙏🏽🤗🙏🏽🤗
    I have also been diagnosed as having childhood PTSD. It has truly been medicine for me my entire life. Today I get to grow 6 beautiful plants a year. Thank you Grandfather and thank you Mother Earth. 🙏🏽🙏🏽🙏🏽🙏🏽

  34. hi, I been smoking weed multiple times daily for the past 10 years, I'm 26 now, but during this whole time, I always been one of the top students in every school I went to. I never took any note in college, but even Now I can still remember in details any of my freshman year classes, or classes I took in high school. So I don't believe canabis affects your memory, unless I'm smoking to forget something. 😉 lol

  35. "people who use A LOT of cannabis… Like every single day for extended periods of time" 😂😂😂 that's me I've smoked daily except for a few months on probation since 2004.

  36. Marijuana has always been a racist drug use by politicians. prisons continue to be full with black and brown people!!!

  37. I love these videos that try to make the laws against pot were just some conspiracy to stop people from using the drug for racist or ignorant reasons. Marijuana is harmful to your health in chronic use. Anyone who knows a pothead knows this.


    If I have this canabinoid things in my body that means God knew why he brought this plant in the world ❤
