While the association between drug sales and violence has been a central focus of gang research since the 1980s, the issue of drug use within gangs has been given much less attention. This is especially true in the case of marijuana. This lack of interest is surprising given the extent to which gang members use marijuana. Other than alcohol, marijuana is the most widely used substance in gang life. In examining the culture and role of marijuana in the lives of gang members, we highlight the integration and normalization of recreational drug use within their day-to-day activities and cultural practices. In doing so, we emphasize the similarity of the role of marijuana in gangs to its role in other youth groups. Data for this paper are drawn from the results of an on-going qualitative study of street gangs in the San Francisco Bay Area, in which 383 male gang members from three different ethnic groupings were interviewed.
