Marijuana
by Dr Lester Grinspoon and James B Baker
Dr Grinspoon is a psychiatrist and he initially approached the whole subject of medicinal cannabis with a rather unfavourable outlook. He was meant to be writing a report for the US government on the effects of cannabis but, as he himself says, the more he delved into the subject the more he realised that the presumed harmfulness of cannabis had been exaggerated for political reasons, and he found cannabis to have a series of positive effects on health. So he started to gather information from patients, which formed the basis of this book.
