Marihuana : a signal of misunderstanding : the official report of the national commission on marihuana and drug abuse / with a special forward by Raymond P. Shafer, chairman.

"Approximately 24 million Americans have used marihuana at one time or another! Marihuana is today's most emotion-packed, controversial issue. Public confusion is monumental. Bombarded with conflicting information, the public no loner knows what to believe. There is vast uncertainty and resentment over widely differing penalties for its use and possession. Yet, illegal though it is, marihuana use, long regarded as a protest symbol of the young, is now spreading in the Establishment, finding acceptance by people of all ages in tha arts, sciences, professions and business."--Back cover.
