Youth gangs are a major part of the urban landscape. Gang members always have been involved in collective and individual violence and, in recent years, in drug use and drug dealing. Involvement in drug dealing recently has been associated with increased violence among gangs. However, variation in organizational and social processes within gangs suggests that there also will be variation in drug-crime relationships among gang members. Analyses of the drug-crime relationships were conducted from interviews with 151 gang members in three cities. Four types of gangs were identified, and similar gang types were observed in the three cities. All gang types had high involvement in drug use, but drug dealing varied. The severity of collective gang crime was associated with the prevalence of drug use within a gang. Drug dealing occurred among gangs with both high and low involvement in violence and other crimes. Involvement in cocaine, opiates, and PCP occurred among both violent and nonviolent gangs, as well as among gangs with different involvement in drug dealing. The results suggest that the drug-crime relationship is skewed and spurious for gang members, similar to relationships among nongang inner-city adolescents. Members of violent gangs more often reported the existence of several features of social organization and cohesion in their gangs, independent of gang involvement in drug use and dealing. Similar to other urban adolescents, for gang members violence is not an inevitable consequence of involvement in drug use or dealing.
