Mr. Louria was the chairman of the New York County Medical Society Committee and has monitored the scene not only from New York State (with its very active addiction program) and the East Village to the West Coast but on to England (where the incidence of drug usage has tremendously increased) and Stockholm (with special forms of drugs now taken). It is ""a disease of the uncommitted,"" and he has to a degree indicated cultural causes and related it to the hippie movement. Very leery of the Professor and other sponsor-prophets (Watts, etc.) he indicates the dangers throughout, potentially as great in marijuana as in LSD, and all a part of our ""national drug-oriented hypochondriasis."" Findings and studies support this, and Mr. Louria evaluates the merits and limitations of programmed therapy and rehabilitation whether voluntary (the addict must be motivated) or mandatory. . . . A stringent analysis with particular value on the semi-professional level.
