title: A comparison of alcohol, drugs, and aggressive crime among Mexican-American, black, and white male arrestees in Texas.
abstract: Few comparative studies exist examining the relationship between substance abuse and aggressive behavior under different social conditions. We studied the relationship between aggressive crime and substance abuse among Mexican-American, black and white male arrestees in Dallas, Houston, and San Antonio, Texas using existing 1992 Drug Use Forecasting (DUF) data. The aim of the analysis was to predict the outcome of aggressive crime from drug and alcohol-related and ethnic group variables within the total male sample (n = 2,364). Results indicated that ethnicity was significantly related to aggressive crime. Mexican-American arrestees were more likely to be arrested for aggressive crimes than either blacks or whites. Drug and alcohol use effects were found across all ethnic groups. In general, the subgroup which drank frequently and tested positive for drug use was less likely to be charged with aggressive crimes than the other subgroups. The psychopharmacological influence of alcohol as a disinhibitor and drugs as a inhibitor provides one explantation of the results. Specific ethnic subcultural and ecological influences also affect the outcome. Our study strongly indicates the heterogeneous character of the drug using population in relation to aggression. The variability between subculturally defined subgroups requires detained ethnographic field studies in the future to describe the contexts of substance use and aggressive behavior.
