Younger cannabis users have reduced brain function, finds largest study yet

  recent and heavy lifetime cannabis use was associated with a statistically significant reduction in brain activity only during the working memory task.

  That’s a much smaller impact than the headline would lead you to think. If you’re not a heavy user, or you’re a heavy user but not for the past month, then you are unlikely to see significant mental changes. And even if you do, it’s only for short-term working memory, no other types of mental ability.

    Yeah, it seems pretty obvious to me that you don’t remember things well while you’re high, just like you don’t remember things while you’re drunk.

      That’s a good point. It would be interesting to see how this relates to alcohol and if they see similar effects.

    Also I’d like to see it done on a “heavyweight smoker” who’s not uses cannabis for say, six months to a year.

    Because I think all of the heavy lifetime users were also actively blazed as fuck.

  I’d be amazed if it didn’t have any negative health consequences - very few things in life come without trade-offs. The real question is how significant those consequences are and whether the benefits outweigh them. For many, the answer is yes.

  This isn’t even remotely news. It’s just bullshit propaganda scare test tics pushed by the fascists. We knew this back in the 90s.

  Don’t smoke weed until you’re about 21, or it will suppress your natural brain development. cannabis, verifiably affects, negatively, Neuroplasticity during adolescent development.

  After 21 or 22, have at it!

      Nixon and Reagan’s war on drugs. It’s a vector that you can easily attack to villainize people who’ve committed no crimes, but need to be jailed to silence dissent

    Your brain is not fully formed until about 25

      And recent studies have indicated it could possibly be even later.

    Ideally 25 :/

  What was that? I was stoned and I missed it.

  As someone with ADHD, I have noticed no difference on working memory other than when I am actually high. Also sounds like this is not permanent since effects go away after a month of no use, but heavy users may suffer withdrawal

    The interesting thing about weed and ADHD, is that, since weed is a stimulant, if you find the right microdose (edible) it’s super super energizing and you can focus even better because it’s stimulating the under active executive part of your brain.

    I will say that I tend to use quite a bit and The withdraw can sometimes be annoying. Nowhere near as tough as other addictions, I’m sure, but the one that always gets me is the loss of appetite and nausea with mild insomnia for a couple days. After I’m over that hump, though, it’s right back to normal. I don’t even get a ‘hankering’ for weed. I just sometimes wish I had some on the initial withdraw days just to help with sleeping and eating, not even because I want the high.

    It’s pretty incredible we have a drug that you can use that much and bounce back out so quickly (assuming you’re old enough).

  I smoked a lot of pot as a kid in the 90s. Is my life ruined now?

  • stembolts@programming.dev ⁨16⁩ ⁨hours⁩ ago

    No. But you have reduced brain function.

    source

    • Lexam@lemmy.world ⁨16⁩ ⁨hours⁩ ago

      That’s ok. I don’t think I want to live in this world with a fully functioning brain.

    Yes, but for different reasons

  Has a similar study been done with tobacco?

  Glad I had my first hit at 37 after it was legal.
