The overall finding indicated that, although there were statistically significant relationships between the predictor variables and the different offense categories, in general, the magnitude of these relationships were low to moderate in value. Black youths were more likely to commit subsequent violent crimes and drug offenses than white juveniles. There was a significant relationship between youths' test results for recent cocaine use and their subsequent referrals and arrests for property felonies and misdemeanors. The data indicated that few youths received serious treatment intervention during the follow-up period, despite research proving that criminal behavior increases following addiction, and that arrests for drug and property offenses decline with decreasing frequency of drug use. 12 tables, 72 references, and 1 appendix
