A fact and figure debit sheet on drugs, particularly heroin, by the young go-ahead U.S. Attorney for the Southern District of New York which provides the basics on the illegal narcotics traffic. Whether it's the 40 to 100 dollars a day on the upkeep of a habit or the 1 to 3% of the international output diverted into the black market here. The former is well controlled; but state and local effectiveness is thin with a poor rate of interception. Seymour gives an expanded outline of the etiology of addiction and the social conditions or personal needs which favor it; you might wonder whether a ""happy home"" is enough to deter the teen-age addict, or whether the methadone program (strongly promoted in. Seymour's home state) is as effective as he claims -- Daniel Casriel's Daytop (p. 842) calls it ""worthless."" Seymour also discusses marihuana and while finding the criminal sanctions too high, does not come out for its legalization before proof of its harmlessness has been assured. And he concludes with an action program which is as more and less workable as any. As background, a serviceable filler on the issue so paramount in the foreground.
