Patterns of Drug Use: A Study of 5,482 Subjects

Drug use was studied in a sample of 5,482 enlisted men on active duty. Twenty-seven percent of the subjects reported having used marijuana, amphetamines. LSD, or heroin. The authors conclude that their data may provide a more realistic estimate of the incidence of drug use than those of previous investigators because the sample is large, subject participation was complete (100 percent), and the sample represents a broad range of educational backgrounds and geographical areas.
