    I wonder how many of them smoking weed vs non-smoking weed kids will become engineers.

    Couldn’t we just impose laws that demand moderation where we can? Like don’t sell to someone who’s already clearly baked, don’t sell more than X at one time, something along the lines of that? It also seems a little odd to make the drinking age lower than the age for recreational marijuana since, from what I’ve heard, it affects the brain less than alcohol.

    chris Brown on what pot does to you

    Unfortunately some people still want to believe this kind of BS. When the fact is cannabinoids encourage neurogenesis It amazes me that just because someone has Dr in front of their name they can spout any old BS that the gullible will lap up to help strengthen there prejudicial assumptions.



  5. Jared Bazzano on December 23, 2020 at 11:00 pm

    God I love weed



  6. SENNYWAVEKID The Youtuber on December 23, 2020 at 11:01 pm

    There is nothing wrong with weed dumbasses weed is supposed to mess with ur hard it’s called being high



  8. Sublunary World on December 23, 2020 at 11:02 pm

    Our monetary system if a far bigger hindrance to our youths getting a good education than someone smokes a joint or not and I am sure getting caught and a criminal record is a far bigger problem when it comes to jobs than smoking it is .. addictions no matter the drug is a medical problem not a criminal one …



  9. liongo on December 23, 2020 at 11:02 pm

    Im 15 I smoked(weed) first when I was 13 from then I didn’t do it alot here and then but when I turned 14 almost 15 istarded a new school i didn’t care about learning and I got in to trouble alot so I smoked weed after school I used to take from my dad’s weed afew times a week for like a few months then my dad found a half a joint in my drawer and he was disappointed and i was scared so I stopped smoking it for a while then I came back to it but every once in awhile me and friends used to do bongs so I became addicted at the start of Summer brake and I also got kicked out of that new school and most of my friends didn’t smoke back then so I had this friend always used to tell me it’s bad for me and i did not listen so I checked it out what it does turns out I was running my brain at a young age and all that stuff so I stopped smoking weed now I’m like two months off of it I feel better and I found some jobs now that I’m off of it all of those friends that told me to stop started smoking and it just hurts me to see all of my friends becoming addicted to the plant like I was now nobody will listen to me when I say it’s not going

    You know what would happen if he quit Marijuana cold turkey? He’d be in a bad mood for a few days and that’s it



  11. 79tazman on December 23, 2020 at 11:03 pm

    Teens will smoke pot even if it’s Illegal or legal I know I did when I was a teen I smoked all the time I quit smoking pot since those days but what ever the case they will do it whether right or wrong.



  12. BR Pqn on December 23, 2020 at 11:04 pm

    any argument against canabis is destroyed by simply stating that alcohol is legal. If one of the most destructive drugs is legal, than all bets are off.



  13. Steven Cook on December 23, 2020 at 11:06 pm

    I smoke what’s up



  14. Ryder Maxwell on December 23, 2020 at 11:06 pm

    I would just like for them to show these terrible damaging effects



  15. Soggy Content on December 23, 2020 at 11:07 pm

    it affects the "problem solving" part of the brain



  16. XXX TENTACION on December 23, 2020 at 11:09 pm

    Chris…. Brown??



  17. Machinedead on December 23, 2020 at 11:16 pm

    I used to smoke but i had nothing and then i stopped and became an astronaut, true story ~ Donald Trump



  18. Crisp Mute on December 23, 2020 at 11:17 pm

    CBC bias alert



  19. DrasticK RebEL on December 23, 2020 at 11:18 pm

    There’s a reason why this video has more dislikes then likes it’s because it’s misleading and bias and done by corporations who own the pharmaceutical companies this is ridiculous



  20. oterenceo on December 23, 2020 at 11:19 pm

    Excessive drinking of alcohol during your teenage years can prevent you from being a golf pro. So ban alcohol?



  21. terry hollands on December 23, 2020 at 11:22 pm

    Alcohol has caused more problems in my life than all other drugs combined. Fact.

    "Marijuana smoke smoke contains a similar range of harmful chemicals to that of tobacco smoke (including bronchial irritants, tumor promoters and carcinogens. As inhaled smoke comes into contact with airway and lung before being absorbed into the bloodstream, it is likely to affect the respiratory system. Risk of respiratory effects from inhaling marijuana smoke are heightened by the more intensive way in which marijuana is smoked — when smoking marijuana compared to tobacco, there is a prolonged and deeper inhalation and it is smoked to a shorter butt length and at a higher combustion temperature. This results in approximately 5 times the carbon monoxide concentration, 3 times the tar, and the retention of one-third more tar in the respiratory tract. Higher levels of ammonia and hydrogen cyanide have also been found in marijuana smoke, compared to tobacco. A 2011 systematic review of the research concluded that long-term marijuana smoking is associated with an increased risk of some respiratory problems, including an increase in cough, sputum production, airway inflammation, and wheeze – similar to that of tobacco smoking. However, no consistent association has been found between marijuana smoking and measures of airway dysfunction. Occasional and low cumulative marijuana use has not been associated with adverse effects on pulmonary function the effects of heavier use are less clear. Additionally, many marijuana smokers also smoke tobacco, which further increases the harm. Numerous studies have found that the harmful effects of smoking marijuana and tobacco appear to be additive, with more respiratory problems in those who smoke both substances than in those who only smoke one or the other."

    CNN / Bigpharma LIES!
    Studies since the 90’s have shown that cannabis helps to repair and even replace damaged brain cells.



  24. Say Jingler on December 23, 2020 at 11:22 pm

    I’m 15 and I smoke weed every few days



  25. Jonathan Shin on December 23, 2020 at 11:22 pm

    just because the government says weed is bad doesn’t mean it is actually bad… marijuana doesn’t have any significant long term negative effects. Scare tactics don’t work because they aren’t true



  26. StrayX09 on December 23, 2020 at 11:22 pm

    If he truly believes that, why not just stop consuming?



  27. Yung Rvin on December 23, 2020 at 11:24 pm

    If I could go back. Then I would of never touched weed



  28. StephenAndrew777 on December 23, 2020 at 11:25 pm

    He doesn’t need pot. What a joke. He just needs a better excuse to grow up than he’s currently got.



  29. Bruno ffs on December 23, 2020 at 11:25 pm

    Wtf just stop smoking weed!Ive met people who have come off of 20 year heroin habits for christs sake and you can’t stop smoking pot?



  30. Changesomthing on December 23, 2020 at 11:26 pm

    Yeh I think 21 is a good age



  31. Tantei Chan on December 23, 2020 at 11:26 pm

    Oh no, look at the offended pot heads.



  32. gbriank1 on December 23, 2020 at 11:27 pm

    Ahh, more "reefer madness". Does affect the brain, sure it does. So does: alcohol, prescription drugs, over-the-counter drugs, illegal drugs, huffing spray paint/markers/gasoline, nicotine, caffeine, bath salts

    When will we just stop telling people what they can’t do to their bodies? 46 years of "War on Drugs" doesn’t have much to show for it.



  33. Omnirex on December 23, 2020 at 11:28 pm

    "Give young kids a few more years before the THC starts affecting their heads" *DUN DUN DUN!!!*

    Clearly somebody doesn’t know how weed works.



  34. MrCoolman980 on December 23, 2020 at 11:28 pm

    I think it’s funny he says it ruins his life. Dude a waterpipe. A waterpipe. He is using the most effective way to get high then says it should stay illegal.



  35. DrasticK RebEL on December 23, 2020 at 11:30 pm

    What about the fact that marijuana as you call it which is really cannabis is not even marijuana that’s a Mexican drug it creates new cell growth thus making it more difficult for brains to be conditioned and brainwashed because that’s what you do with kids these days is you brainwash them into thinking the world is completely different than what it is and then they wake up and realize it’s different in the cause all kinds of problems but then you call them bipolar and manic



  36. cortarelva on December 23, 2020 at 11:30 pm

    Weird!
    Alcohol has been destroying lives for centuries and I don`t see any bullshit doctor do anything to stop it.



  37. Krista Molnar on December 23, 2020 at 11:33 pm

  41. pewpewkad7 on December 23, 2020 at 11:40 pm

    That guy is just making excuses for why he’s not a golf pro



  42. Steven Cook on December 23, 2020 at 11:41 pm

  43. NightShade The Wolf on December 23, 2020 at 11:41 pm

    Yea sure maybe your just a failure in general or just always sucked



  44. chubrik zhopa on December 23, 2020 at 11:43 pm

    Should I say this vid is dope lol sorry



  45. McDinaldo on December 23, 2020 at 11:45 pm

    Weed should be available at least as early as alcohol, considering alcohol is, in many ways, worse than it.



  46. FUCK THE WORST on December 23, 2020 at 11:45 pm

    Weed can’t hurt you unless it’s everyday or every 2 days and if it’s a minor smoking marijuana with thc in it he or she can surprisingly develop psychosis or even schizophrenia but if it’s hemp it’s different



  47. Diana Shane on December 23, 2020 at 11:46 pm

    While chatting with Dilan, I was surprised to notice him being so witty and sharp. Finally, he mentioned that he had googled Nemery Thentel’s website and got everything he needed to quit weed in a week, I’m working on it myself now.



  48. maxitout on December 23, 2020 at 11:48 pm

    anyone here watches dope as yola



  49. Alex Nikopoulos on December 23, 2020 at 11:48 pm

    You turned yourself "into something I don’t like", not weed. It is your fault you allowed your weed use to degrade your functionality.



  50. taibhsear71 on December 23, 2020 at 11:49 pm

    Yeah, and alcohol has no negative affects on developing brains either, but it’s legal. How about tobacco? Are there any health cost related to it? And just ignore the prescription drug issues.
