Sudafed is more of a controlled substance than pot. Banned stuff is just about the least "controlled" stuff there is.
    Amen.
    The morality of abortion is not a religious belief, any more than the morality of slavery, apartheid, rape, larceny, murder or arson is a religious belief. These are norms of the natural law of mankind and can be legislated even in a completely religionless society.

    This is what's troubling me.

    I reason that after a person turn 24, the brain generally stops "developing." Though brain cells are being replenished naturally, like all cells in the body, one would think that marijuana would kill more brain cells in adults than there is to replenish.... and that if one smokes marijuana while young and then stops, at least the brain would still be developing, making up for some of the damage.

    I don't know really.


    Only thing I can say is that most long-term wake-and-bake heavy stoners I've known didn't exactly come across as intellectual giants.

    Cell death is not the mechanism of cognitive impairment. Even at blush this is apparent as there is no fatal dose level for the psycho-active ingredients. They are receptor binders. The only way to kill yourself with the mary-J is suffocate yourself by trying to hotbox using a plastic bag over your head, or go tightrope walking after sparking up.

    This study certainly does not assertion the mechanism behind the trend it measures. It could easily be as simple as the kids not paying attention and exerting themselves mentally during key learning years. I did not see a link to the study in the article, which raises all sorts of flags for me but also means I cannot really get a good idea what they have tried to control for to make sure this was not a case of self-selection.

    "The findings are pretty clear that it is not simply chronic use that causes deficits, but chronic use with adolescent onset."

    It has long been noted and widely accepted that poking around brain chemistry during adolescence, with any psychoactive substance, is riskier than after reaching adulthood. That is why pharmaceuticals regs require separate approval for pre-adults, after adult approval is accepted, in various age bands. This is not really that unexpected but still good to have some data on it.

    Re: Marijuana and IQ Damage

    I've know several people who have smoked probably 25 years, several times a day, per them,,,,,,,, don't know if that is considered heavy or not, however, when I'm around them at work, I see No problem with their thinking ability or work ability, I do know they aren't smoking at work as there is no place or time to smoke w/out getting caught, So with them I would say No, hasn't affected their brains, Not yet anyway.

    Key word: Adolescent. We're talking about big boys here.

    I don't see too many people arguing that little kids and teenagers should be buying it, as is the status quo. dealers don't card. it's much easier for a kid to buy pot than alcohol.

    that being said, is pot totally harmless? no. is it less harmful than legal drugs? yes.
