So one study that is no longer public, and another that is 12 years old is your definitive proof that 1 joint causes 0.2 now? % increase chance in schizophrenia? Am I getting that right?
I'm also reading that the most at risk from marijuana according to these studies are adolescents. The legalization movement in America is, to the best of my knowledge, setting the minimum age one can purchase the drug at 21. I wonder how it would affect these numbers if you removed the 15-20 cohort?
Hmmm
