    Wish he would have mentioned if the effects on the amygdaloid and
    hippocampus were good or bad. Simply stating that it changed the structures
    and so could change the respectable performance is poor.

    Weed makes you lazy but if you have strong curiosity.. the two can be a
    great combination for a period of time in my opinion.

    It’s a question I was wondering myself in a way more or less, I became
    sharper in over thinking a subject I’m interested in, and the subject made
    sense in the smallest details, when I had to redo my final exam in bible, a
    subject that I failed with 0 questions answered, I passed it with a real
    high score. Scientists say that underage weed smoking can interrupt your
    brain development, in my opinion it interrupt is a harsh word, I would say
    changes the development in a bad way and a good way.

    Maybe, though given the limitations listed it seems hard to say that they
    even know that. If the studies were small, who’s to say these people didn’t
    already have these abnormalities? I think the only thing that can be said
    is we don’t know if it’s good or bad. And I think in all probability it
    depends completely on the person.

    psychosis? are you sure that it’s just pot that he’s smoking? i’ve never
    heard of anybody completely losing touch of reality from smoking weed.

    I can say with all honesty that my memory dropped and probably some of my
    IQ too. I don’t look at things the same way anymore, but when i don’t use
    it it get’s somewhat back to normal

    I’m glad.

    Great video, thank you so much for sharing! It would be great if you could
    explain the relation of anxiety to marijuana. I have experienced an
    intersting correlation where after prolonged use, some individuals
    experience anxiety most times when they smoke. I am wondering if this is a
    physiological or psychological affect, as some have said that by focusing
    on the anxiety they are able to work through subconcious problems bringing
    themselves to the surface. Thanks again :)

    Sorry but this is anecdote. Meaning worthless data. Does he do other drugs,
    does he have a hereditary illness, what does he eat, how much does he
    smoke, strain, etc… You cannot blame the plant marijuana for these
    problems. It’s an extremely diverse plant with a lot of different potential
    uses depending how it is grown and processed. I know how easy it is, given
    the controversy around it, but just try looking up CBD. If you’re bold,
    grow him some weed that’s high in CBD and see what happens.

    Fantastic presentation!

    My son smokes marijuana (much to my distress) and his cognitive processes
    have declined a fair bit. He lacks organisational ability, motivation,
    pretty eratic with his thinking and emotions and he is always losing stuff.
    It also caused him to experience 3 episodes of psycosis so far. I hope you
    do more research to understand the real impact of marijuana.

    More Dr.’s need to be like this guy; honest, straight forward, and not
    trying to cover up the facts which most do.

    There are long term studies by our government. Here in the U.S. There are
    people that receive weed from our government and have been for years!

  21. Sam Piazza

    well unlike uncaring people like you, i for one want a healthy brain, i
    dont know about you but memory is important to me so if that means i stop
    smoking weed then im going to stop, hopefully more research will be done
