Most of the facts and the incontrovertible truth here have been aired in other books, most recently Donald Louria's The Drug Scene (p. 583) and Mr. Oursler refers to Mr. Louria at intervals, covers some of the same terrain without going into the questions of programmed therapy and rehabilitation. One in 150 now smoke marijuana; ten to twelve percent go on to heroin (usually the more unstable). Based on extensive taped accounts of various users and abusers, on the investigative-legislative efforts and positions of many working with this problem, this also discusses the penalties and the question of whether legalization is justifiable, the affiliations with the underworld and difficulties in controlling dissemination of drugs, the mystique and some earlier swamis of the soma, and coverage of urban and suburban (particularly Westport, Conn.) incidence. A satisfactory and very reasonable presentation, and while McLuhan contended that ""turning on"" in our ""electric circuited culture"" was inevitable. Mr. Oursler's conclusion is far more persuasive--keep off the grass.
