1995 Drug Use Forecasting Annual Report on Adult and Juvenile Arrestees presents rates of drug use among adult male and female arrestees and among juvenile arrestees/detainees using urinalysis to detect recent use of drugs. The analysis of adult arrestees focuses on trends in the use of marijuana, cocaine, and opiates, and special attention is given to trends for the youngest adults (age 20 or younger). Also featured are site-by-site graphical presentations of data collected in 1995 for adult arrestees and for juvenile arrestees/detainees. In 1995, the DUF program surveyed 20,737 adult male booked arrestees at 23 sites in major metropolitan areas across the United States. Data from 8,065 adult female booked arrestees were collected at 21 of these sites. In addition, 12 sites collected data from 4,293 juvenile male arrestees/detainees. Findings included: In general, cocaine use among adult male arrestees continued to decline, and marijuana use among adult male arrestees continued to escalate.
