From the back cover:
In recent years, the use of marijuana by growing numbers of people in all walks of life has become one of the most burningly controversial issues with which our society has come face to face. Yet, in spite of the continual furore in the Press, on TV and on the radio, most people probably know little, if anything, of the marijuana facts — its effects, history and pharmacology — as distinct from the marijuana myths. What exactly is its relationship to sex? To violence? To crime? To addiction? Is it really harmful? Or perhaps beneficial? What and where are its sources? To these and many questions, the doctors, scientists, sociologists and writers in this volume provide illuminating answers backed with a wealth of evidence.
