title: Adolescent drug using groups in Chicago parks.
abstract: In a northern Chicago neighborhood, observational and interview data were collected at parks, school lots, and beaches where adolescents congregate to buy, sell, and use nonopiate drugs. These sites were geographically distinct from areas where heroin is regularly distributed. Users at each area generally resided in the immediate neighborhood, were well known to one another, were predominantly male, displayed similar socioeconomic, religious and ethnic backgrounds, and had attended the same grade schools and high schools. These sites were relatively stable during the summer months, although visitors occasionally changed locations in response to police harassment. Attendance fluctuated with weather and time of day. Drug use was generally confined to the daily use of marihuana and weekend use of alcohol and sedative-hypnotics, but availability seemed to determine the type and frequency of drug use to a greater extent than drug perference. This study suggests the potential of a fieldwork model for prevention and intervention activities prior to the  onset of more intense and diversified drug use.
