John Henry, MD Biography

Title:
Former Professor of Accident and Emergency Medicine at St. Mary's Medical School in London
Position:
Not Clearly Pro or Con to the question "Should Marijuana Be a Medical Option?"
Reasoning:

“There’s no government health warning against cannabis but there are all kinds of warnings about tobacco. People who want to smoke cannabis ought to be aware that it has equal effects to cigarettes on the body and worse effects on the mind. You’ve got the fact that regular cannabis smokers develop mental illness. There’s a fourfold increase in schizophrenia and a fourfold increase in major depression. That is something very very different from what smoking does to you. There’s a lot of epidemiological evidence from as far apart as Sweden and New Zealand that cannabis actually causes these problems.”

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.]
