Does this include the possibility that teenagers with lower IQs tend to smoke more marijuana than teenagers with higher IQs?
*************************
A logical question from a Centurian driver...
My question is How does IQ change when you compare with people that smoke beginning after adult brain development occurs ,,, lets say 25+ years.
Judging based on the linked article, neither of our questions were considered, as they are too logical. No, they concentrated on answering esoteric things... Eg, second hand smoke, prenatal, and the like... Things more likely to garner funding.
