3. Medical Marijuana
Position:
No position found to the question "Should marijuana be a medical option?"
4. Reasoning:

"Findings suggest that regular cannabis users are significantly more prone to cognitive and perceptual distortions as well as disorganization, but not interpersonal deficits, than non-regular users and those who have never used. Additionally, the onset of schizotypal symptoms generally precedes the onset of cannabis use. The findings do not support a causal link between cannabis use and schizotypal traits." "Symptoms of Schizotypy Precede Cannabis Use," Psychiatry Research, 2005
