Hispanic and black juvenile delinquents were more likely to be heavily involved with criminal activities and drug abuse than whites. Hispanic juveniles were more involved with cocaine and its derivatives, particularly crack, than either blacks or whites. Hispanics were as likely, if not more likely than at least the white juveniles, to be involved with illegal activities such as drug sales, theft, prostitution, and robbery. At the time of the survey in 1986 and 1987, 77 percent of Hispanics were using cocaine on a daily basis, compared to 46 percent of white and 67 percent of black juveniles in the study. Hispanics were the least likely to ever have sought treatment for drug or alcohol problems. 2 notes and 3 tables
