The Canadian Medical Association Journal had an article about heavy marijuana use causing a decline of 4.0 points in IQ over the long term.
Had a chance to read the article fully, and here's what was left out of what was in the newspapers:
Oddly, in the results section, the authors somehow come to the conclusion that the proportion of the population with IQs below 70 (borderline retarded) would increase to 5.5% from 2.3% with a decline of 4 points overall.
What they fail to note is that if everybody smoked marijuana in moderation, the proportion of the population with IQs above 130 (S-M-R-T people) would increase to 6.2% [just guessing, but I'm a light smoker, so it's probably right on
] from the current 2.3%.
Love those idiots who write this shit.
Thinking of writing them a letter, but I just sparked one up: might increase my IQ, but it certainly does nothing for my letter writing motivation
Had a chance to read the article fully, and here's what was left out of what was in the newspapers:
* light users (<5 joints/week), IQ scores went up by 5.8 points
* non-users, IQ scores went up by 2.6 points
* former users, IQ scores went up by 3.5 points
