John Henry, MD Biography

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

“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.”
