I believe that this work will be of interest to workers in any of the disciplines involved in treating chemical dependency. Although the concepts are basic to psychiatry, there is considerable information presented here, by and large in the form of data and statistics on the prevalence of the different forms of abuse in the several ethnic populations. For example, one chapter estimates that the incidence of fetal alcohol syndrome in Native Americans is five or six times that in the general population (p. 285). Another chapter reports on treating opium-smoking problems among the Mien people who have immigrated to Oakland, Calif., from Laos. In their mountainous home in Laos, they cultivated the opium poppy and smoked it at all ages for a variety of symptoms. There was no stigma attached to its use in their homeland (p. 156). The chapter titled "Hispanic Heroin Users: Up Close and Personal" reads like an anthropological field study. Its author, an anthropologist, became acquainted with homeless individuals and prostitutes in a large city’s slums in order to write about the faces of heroin addiction in that setting.
