I’m with you my friend! 💚
😂🤣😂😄
8 years of smoking and been trying to quit for 7 yrs
Typical
@@Pasdpawn same
I’m a 28 year old man, and I started using cannabis for my ASD (severe sensory overload that causes physical pain in my brain) and central fatigue. A VERY fast acting substance with almost miraculous effects (the inhibition of glutamatergic receptors).
Two side effects I have noticed, is laziness and a lack of motivation, and desire to be stoned a lot of the time, as my sensory perceptions are much more pleasurable when high.
I wouldn’t change cannabis for the world. If you use it for a medicinal purpose or use it wisely, it can be a tool for development. I was housebound in silence due to my sensory issues, and nothing worked until I met cannabis.
Good for you man, good for you!

Oh what is this? A objective video with studies that show both positive and negative effects. Wow, does that exist? Can you be that crazy intelligent?? Nah it must be a conspiracy and he must be bought by the pharmacy company and all the studies too. But wait, why is talking about the negative effects when it comes to other medicines? Could it be that it is possible to see further than your own nose?
Nah, CoNsPiRaCy. Has to be, right???
Fantastic video! The value of mental health education should be taught in schools. Continue the excellent work!
Nothing better than a guy who's never been high talk about driving high
I thank the creator for this miraculous plant. It keeps me from abusing the Opiods I'd been addicted to for 15 years. It helps the chronic pain and mental health issues I have as well.
There’s a lot of denial among cannabis smokers. You can see it in the comments of every single video where cannabis isn’t described as harmless.
Plus they are being manipulated by information that is pro cannabis for profit.
They live in a world of denial.
Been smoking daily for 17 years and a advocate for cannabis... People are in major denial about the negative psychological effects. It's a useful drug, no doubt. But people thing it's a heal all cure all. And that there are 0 negative effects, and that's flat out wrong.
Yup
It’s the one drug that’s promoted and not shamed.
A great observation. I have noticed this as well.
I tend to go towards the mellower calm and really relaxing strain it chills me out so much. Its way better than the stimulating and damaging effects of alcohol.
Great information. Thank you for your work.
I have one comment on consuming and driving: what makes a safe driver? The ability to react or the consideration to think ahead? I can only say that the drivers here in germany are incredibly rough and aggressiv and when I see youth driving under the influence they become much more relaxed, taking larger turns, driving slower and generally not taking risks I know drivers who are “rational” are culturally inclined to do. So I think it depends on context. If you are taking a freeway best be clear, because reaction time is of importance. When it comes down to social driving I think influence can reduce aggression and risk taking.
Weed hardly affects your driving, only 17 or so die a year because of thc accidents
Awesome upload! They should teach the importance of mental health in schools. Keep up the great work!
Useful information. Thank you. In the “old” days we knew to leave sleeping dogs sleeping. We had psychological problems, with paranoia in my family so I chose to leave the sleeping dog alone.
Weed caused me to have a nervous breakdown with severe neurosis, anxiety and OCD... So whilst it's usually fine for most people, it's definitely naive to say that it's never harmful.
@@Filthycoffin yeah whoever say weed is not addictive is talking out their arse. I got severe lead and Mercury toxicity from the sheer amount I was smoking too. These are all the things you don't hear these days. Not gonna lie I fuckn miss it but life's more meaningful without it. All the best 💪
@@samford5153 that sucks I never knew the poisoning could happen how did you clear your body of the heavy metal buildup? I’ve got some trs spray I was thinking about trying to remove heavy metals.
@@Filthycoffin you can do dmsa treatment as the quick option or take NAC, glutathione and L-Methionine for about a year.
I cannot speak for us and Canada, however here in Europe I can guarantee that a lot of the side effects correlated with marijuana use are from secondary substances that were added to the batch in order to sell better on the black market. When looking at studies with certified medical marijuana the harm seems reduced. I have heard of jitteryness and anxiety in some individuals due to their body processing high amounts of CBD differently. So if it’s anxiety that is triggered, it may have to do with that aspect.
All said and done, you may just not respond positively to weed on a biological level which can happen. Hope you found something that works for you.
I am on day 2 of withdrawal, and it is complete hell.
MJ might be fine for most people, but it has been a monkey on my back for 40 years.
Maybe I'm weak. But I'm sure I'm not alone.
What I’d like to know is the cannibas is bread to have more CBD than THC will that protect the brain from the negative effects of the THC while still enabling the person to enjoy a stress free slightly euphoric experience? Because CBD is neuro protective I’ve heard and lightens some of thcs effects.
They basically counteract each other. Weed with very high cbd gives very little "high feeling". Smoking weed with little to no THC does absolutely nothing. I've tried CBD weed a few times and it's just cannabis flavoured cigarettes essentially
The non-psychoactive cannabinoids somehow negate the addictive properties of THC. High CBD strains, which still contain noticeable amounts of THC between 1-5%< will reduce cravings for other addictive drugs such as alcohol and they are not addictive.
Too much cbd is not good.
@@ALMArt-ko9yu In what way? The side effects of taking too much are mild from everything we have researched. I'd love to see the source.
@@CBDPiggy clearly not enough research done then ay...
Are you a neuroscientist?
Obviously not....
Great lecture thank you
Can someone tell me in short, can i smoke a joint now.???
Yes
😂I'm rolling one while I'm listening this 😂
Amazing stuff - thanks
Awesome presentation. Intelligent, informative. Thank you!
It is useful information for me.
I have tried thc for pain issues , post surgery, repeated surgeries.
This was directed by a medical doctor.
it gave me a general sense of discomfort, perhaps more suspicious and less productive.
imo, the single greatest practice to improve mood, improve mobility and lessen negativity is cardiovascular exercise.
Exercise also builds a person's self awareness and builds confidence.
My question therefore is....Why do younger people , (the biggest user group of cannabis) not employ more exercise to combat their physical health and mental health issues?
Body mass has obviously increased in the younger generations, and because of this athletism has decreased, mobility has decreased etc.
I will say that I was a longterm heavy user of the strongest of the opiods for multiple post surgery pain, it didn't work either
I am not as pure as the driven snow , myself.
I am simply asking the question after personal experience.
What kind of exercise do you feel benefits you the most, personally?
One helpful clue is birthday for usefully sorting our various neural parameters. We need to rescue birthday from the archaic notions of astrology and realize birthday is a fundamental dimension of solar energy differences in the developing infant's environment that humans have evolved to respond to with systematic differences in neural development. Currently, we limit our sorting mostly to genetics but including birthday will mean significant progress in understanding and dealing with the variety of responses to cannabis.
The ability to perceive your environment is always better then reality I've never met anyone in my entire life who's had a bad experience maybe a little paranoid just needs a different strength.
Could’ve drawn the link to other disorders especially neurodevelopmental disorder ADHD.
We are never in big trouble and nobody should have to go to the emergency department that is ridiculous and I make edibles all the time I also make tinksters. Guess what we use it in a cream to help with pain usually it's just a CBD for that I don't see that CBD works too well without THC they work good together
I'm useing chaga in my grow
along with Turkey tail mushrooms in my compost tea
amazing results
Amazing 👍
What About Vaping???
Why is no one mentioning vaping cannabis or cbd?
Florida promotes it.
I have been vaping for 3-4 years. Looking for info on risks.
There aren't any reliable studies on the long-term risks thus far, since vaping altogether is a relatively new field. I am sure there are researchers conducting longitudinal studies right now but we won't know until a few years later.
Look up Bronchitis and Emphysema those are the most common risks of smoking anything
I've smoked on and off for awhile. For me it doesn't become enjoyable it gets to be maintenance maybe because of my addictive personality.. I'm going to stop again .. Back to the sunlight of the spirit. If others enjoy it and it's cool that's great.. .
Cannabis improves alertness during driving! If I don't smoke I'm reckless on the road
Lol. Rigghhht.
Irie am in zambia i went to join classes
Okay people saying they are a better driver while stoned are not being reasonable at all. You will ALWAYS be safer while sober, in fact, I know thc seems safer than other drugs but it still isn't safe to drive. You are putting yourself and others at risk and putting yourself at risk of a DUI as well. None of it is worth it.
Ruderalis exists! Its the source of "autoflowering" Cannabis plants 😄
The "negative" physcoactive effects described by this video is so unfounded. Try finding any evidence not from 100s or 1000s of years ago.
With all due respect, I disagree with you.
MJ just stopped working for me and was causing major depression/anxiety.
I'm now attempting to quit (day 2), and it is very VERY hard and uncomfortable.
@@coolworx with all do respect,
That has nothing to do with my comment. .. that is MAYBE from addiction. Mental addiction as well, being that you wouldn't have an adverse side effect physically from quitting. It made you anxious and depressed? Which is something intoxicants can do. Too much or too little on the dosing or bad product to start with. Because I have been smoking for 15 years without it causing those side effects. Infact if most people who do smoke regularly you're story would be rare and I would care to say MMJ was not your problem. Just a facet for you to blame when there is a deeper seeded issue.
Again, I stand by my statement. . I am not going to continue the thread either because to explain this in text is too much work and my point will take too much of my time. I hope you do some reading on the product you claim caused this before you become that person who slanders something you clearly do not understand.
Have a good one.
@@RatherNotYea I completely agree 100% on this one. If you wanna live a healthy life and smoke thats normal. Usually it brings out what's already inside and usually its trauma.
Okay, so RUclips does censor "the Gods." at 47:55-6 and I don't exactly know why, but just thought I would point that one out.
CoNsPiRaCy against the only country in the world - Murica. Or not, because they don't censor it here and you're not so why am I even talking to you
can I have the podcast's link, please?
I vaporizer it and the left overs or put in a cup of tea 🍵
Interesting on the incorrect information in the beginning of the video concerning C. Ruderalis. It IS VERY common as it is used in breeding autoflower cannibis plants (which are used in recreational and medical uses). I think you need to re examine your cannabis knowledge. A glaring error such as this colors all of your following statments.
What's the podcasts name?!
minding the brain! :) mindingthebrainpodcast.com
Legalise cannabis in the UK.
It is astonishing how informed these researchers are on the science, but then completely uninformed on the legal and criminal aspects of what they are discussing
Like what exactly? How are they wrong?
The only difference between a body high and a head high is the color of the trichomes when the plant is maturing and it's flower stage. The different names and the sativa and the Indica are just marketing tools it's not even true I could take the Indica plant and have a sativa buzz and vice versa if I don't let it mature all the way the trichomes I mean if they're clear or cloudy you just get a headbuzz if they're Auburn you get the body Buzz too that helps with the pain in the body
ME AND MY DOG BURNING 🔥. SHE LIKES TO WATCH T.V AND LEARN.SOMETIMES IF SHE GETS TO HIGH.SHE BE STANDING ON HER HEAD L.OL
Great but would have been much better if the first speaker would stop saying “like” and “very unique”.
It's very common, these verbal "fillers" often come up with the anxiety associated with public speaking and presenting! It's essentially the brain giving itself a moment to pause and organise what it is going to say next, though it can also be socially influenced, meaning it stands out more to people of contrasting cultures. For some it can take many years and immense practise to eliminate those little quirks, I just try to ignore it!
Oh stop.
I have cousins who used cannabis just for fun and they became addicted to it, they are previously healthy, but after just 2 or more years they shifted to more stronger drug like meth, addiction is real once you became addict it's hard to get out of it and maybe like my cousins they'd always want a stronger drug, at first there is no side effect like 10 years of using drugs but after 15 years their body shape deformed and the walk like a hungry sick person, getting intoxicated to any drugs does no good but harm to human bodies.
I wonder what the degree of statistical or econometric experience and knowledge many doctors (including neuroscientists) have. It's no surprise that doctors get by without knowing very much about statistics and this whole science of numbers, correlation, causation, etc. I'm very familiar with how ignorant people (even supposedly educated people) can be about statistics, numbers, and economics... Steven Pinker's book, Rationality, makes that clear, as do many books on behavioral economics. There's the great little exercise with the Bayesian theorem and applying it to women's cancer screening (which a large majority of doctors incorrectly understand).
Serious scientists understand proper epistemology and empirical tests. This is why neuroscience has always been bordering on a pseudo-science. It's very weakly, if at all, able to tell us much information about behavior, thought processes, beliefs, or experiences.
For instance, that abysmal early slide that has statistics and a graph. The graph isn't real at all. It doesn't plot anything except a hypothesis of the relationship between perceived harm and rate of use. Any mathematician knows the independent variable should be on the x-axis to convey correlation. Anyway, it would make sense if it at least plotted real values (showing us the wide variation) and used that line as a regression line.
The statistics on that page are horrible. "16-24 year olds 2x more likely to use cannabis" - that could mean nothing at all, or something meaningful, depending on the numbers themselves. Maybe pick up Risk by Dan Gardner to learn about how the media uses statistics so incorrectly as to often give the opposite information as what they actually convey. Or maybe pick up Naked Statistics by Charles Wheelan, or Mindware by Richard Nisbett, or Innumeracy by John Allen Paulos, etc. If 10% of people use cannabis, 2x is a big deal. If 0.5% use cannabis, 2x is still insignificant. Is the 2x being compared to adults, 25-80? Or 25-40? What are the rates?
"Students (37%) used more than ... " - 37% of students used? Or students used 37% more than ... ? Or are students 37% of those who use? Statistics used like this is abysmal. No wonder mainstream media is nothing but scaremongering. And as compared to what numbers? Again, if 10% of people use, then 13.7% of students using may or may not be a meaningful difference. If it's 1% and 1.37%, then it's essentially nothing. If it's 50% and 68.5%, then it might be important. But we don't know with the cherry-picked and seemingly random numbers given.
"Average age of initiation ... " - mean or median? This is important. If 60% of people start using at 30, but 40% start using at 12, then it's clearly not an average person who's initiated at 18.7. The average person would be initiated at 30. A median would be 30, but a mean might be close to 18. If we're to be given an accurate and representative number to estimate at what age people start using, a mean or median might be meaningless. We need more than a vague number.
"Of those who reported using, 18% reported using daily" - Possibly great information if you know what percent reported using...
Maybe skipping the neuroscience and just talking about correlations would be better. 10% of people who use cannabis do X. However, 5% of the population at large do X, so cannabis increases it from 5 to 10% (cannabis has 2x rate of X? Possibly. But that's possibly abuse of statistics to state relative numbers. What matters is absolute values). Eg. People who use cannabis recover from chronic pain at a rate of 30% as compared to non-users who recover at a rate of 15% (made up numbers).... These are the correlations that matter and the proper numbers to use.
Furthermore, we're talking about correlations. Without numbers of the population at large, the numbers given may be meaningless. Maybe it's the same. Maybe it's incrementally and insignificantly larger or smaller. Maybe it makes a big difference. Even then, if it's correlation, then it could be spurious (caused by coincidence, variation, noise), 3rd variable, or reverse causation, not just causation. Without natural (or controlled if possible now) experiments, at least, we can't know much about causation, if at all. There's always more nuance than a snippet or headline or sound bite can hold.
I really wanted some good science about cannabis. It's trouble enough that 90% of youtube or google results give uneducated or mainstream/sensational opinions that have no basis in science or rationality. But even doctors and scientists have very little basis in rationality.
Besides, anyone who's read Doidge's Brain that Changes Itself or Whitaker's Anatomy of an Epidemic (I'm sure there are plenty more pop science books that would tell you this), would know that the brain adapts. If cannabis blocks neurotransmitter X, then the brain will react by increasing receptors or increasing secretion of neurotransmitter X. Clearly, it's misleading to end the story at the first part of that sentence....
I'm just hearing endless variants of "can" and "is associated with" without any real or even mildly useful information/numbers.
What you need is some good hashish🤣
tldw
what a smokeshow
Malarky
Never seen this much wrong information at once!
Which parts mostly would you say are wrong?
Please elaborate and include sources, thanks! Would be useful to have any contrasting information.
Maybe enlighten us ,genius.
Oh, we're quiet now...
None of it is misinformation. Its all factual.
Probably best not to start a cannabis talk by mentioning pizza…
😂
