    Marijuana and IQ Damage

    This issue has been discussed more times than I can count, and partisans from both sides of the aisle have painted their sides of the story.

    So, what's the truth? Last time I discussed this issue, I used this article:

    Researchers found persistent users of the drug, who started smoking it at school, had lower IQ scores as adults.


    They were also significantly more likely to have attention and memory problems in later life, than their peers who abstained.


    Furthermore, those who started as teenagers and used it heavily, but quit as adults, did not regain their full mental powers, found academics at King’s College London and Duke University in the US.


    They looked at data from over 1,000 people from Dunedin in New Zealand, who have been followed through their lives since being born in 1972 or 1973.


    Participants were asked about cannabis usage when they were 18, 21, 26, 32 and 38. Their IQ was tested at 13 and 38. In addition, each nominated a close friend or family member, who was asked about attention and memory problems.

    No one seems to know the number of flip-flops on this issue in regards to marijuana's effect on IQ. What do you think?

    It's not a debate. Marijuana kills brain cells.

    So does tobacco, alcohol, and television.

    From what I see, the damage done to people who start smoking as adults is temporary, and can be permanent for people who start in their youth. This is a great reason to legalize. Drug dealers don't check ID, and legal pot means that it's easier to regulate it out of the hands of kids. In high school obtaining weed was always much easier than obtaining booze. The fact that the government bans pot when there is significant demand for it and no effective way of eradicating it, cannot stop the black market from coming in and controlling the production and sale of the crop, and then calls this product a "controlled substance" is laughable. Sudafed is more of a controlled substance than pot. Banned stuff is just about the least "controlled" stuff there is.

    If people want to smoke weed and become less intelligent then that is up to them, i personally favor legalisation without actually having a joint myself


    Also if it does destroy brain cells, people are only harming themselves. You need two more options 1) Yes it does but make it legal
    and 2) no it doesn't but keep it illegal.

    Re: Marijuana and IQ Damage

    I saw an article once that claimed aging has been shown to permanently lower IQ, too. Just sayin.

    Having read everything I've read, and my personal experiences with the drug, I would say absolutely not. However, considering the jury is still somewhat out on that, let's assume for a minute it does kill brain cells.

    There is an unbelievable number of things that kill brain cells. Some of the most notable being:
    - Too much stress
    - Rapidly shaking your head
    - Junk food
    - Avoiding exercise
    - Drinking too much water
    - Being a chronic negative thinker
    - Lack of quality sleep
    etc.

    Ultimately, however, none of it matters, because your brain is constantly regrowing brain cells. You don't have a limited number of brain cells any more than you have a limited number of hair. (Well I guess some of us do) When cut, it will end up growing back in time.

    Regrettably true. Both pot and aging take their toll.

    I used to have constant business ideas. Now, I can barely keep up with litter-box duties.

    Pot should be legal but I don't recommend it.

    Re: Marijuana and IQ Damage

    I am sure it does. also I am sure that there are too many variables to draw the link that it alone was the factor in the IQ loss. I really have no problem with pot just so it is not around me because of the smell. It is a natural plant and all it takes is to dry it. Maybe if it were more available and accepted, people would/could step themselves off the harder stuff or be deterred from doing the harder stuff because they would not be in for a penny in for a pound on the illegals. I would be ok with hash too. Anything beyond that, is where my line is chiseled in stone.

    This is roughly where the research stands, although I do think it has been establish what the mechanism that imperils pre-adults is, thus “kills brain cells” wording of the poll is right out.

    Heavy pot usage causes certain mental impairments, for example sentence construction. But in adults if you stop smoking and let it clear out the problem goes away, unlike a lot of the damage that alcohol does.
