A glance at the table of contents will quickly reassure the reader that this is far from just another book on marihuana. Here at last is a scholarly work that goes to the heart of the tangled issues surrounding the drug and its use. Professor Nahas has carefully evaluated the scientific data on marihuana and has produced a balanced and objective reply to those who believe that legalization would be a partial solution to its use. In his closing chapters Professor Nahas, speaking as a concerned citizen as well as a scientist, incisively analyzes the social issues which are intimately tied to drug use.
