Professor of Psychiatry and Neuroimaging at the University of Edinburgh

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.]
