Cocaine selling among urban black and white adolescent males.

Data from a longitudinal study of juvenile detainees are used to examine the relationships between cocaine selling, substance use, and other delinquency among the Black and White males in the study. A descriptive comparison of rates of cocaine selling among the youths is followed by a descriptive comparison of prevalence of substance use and other delinquency across four subgroups: White and Black males indicating they sold and did not sell cocaine. These comparisons are followed by analyses of variance examining the relationships between involvement in substance use and other delinquency, and ethnicity, cocaine selling, and the interaction of ethnicity and cocaine selling. Important ethnicity and cocaine-selling effects are found, but not ethnicity by cocaine-selling interactions. The implications of our findings for theory and service provision are drawn.
