Medical Superintendent of Mental Health Services at the Prince of Wales Hospital
Con to the question "Should Marijuana Be a Medical Option?"

“The results of meta-analysis provide evidence for a relationship between cannabis use and earlier onset of psychotic illness, and they support the hypothesis that cannabis use plays a causal role in the development of psychosis in some patients. The results suggest the need for renewed warnings about the potentially harmful effects of cannabis.”

Theoretical Expertise Ranking:
     Key Experts
Physicians [Physicians are the "key experts" in the medical marijuana debate because the issue is thought by many to be ultimately based on the medical value and risks of marijuana, and Physicians, with their training and clinical work, should (at least in theory) have the best knowledge of marijuana's medical value and risks.] [Note: Key Experts definition varies by sites that have this designation.]
