Ten drug-using college students at Muhlenberg College were interviewed to understand these three major research questions: (1) What is the nature and extent of drug use on campus? (2) How are the social relationships and identities negotiated within the social network? (3) What is the nature of the economics and exchange of the drugs on campus? Findings indicated that drug use is most frequently a social act in friendship networks where individuals gather in a ritualized setting. Drug use and dealing within friendship networks are governed by set rules and regulations that are learned by the members of the drug culture. The process of integration into this drug culture involves both learning and teaching these norms, which was revealed in all ten interviews. Unlike most social networks, illegal substance use in a drug-using network illustrated the importance of strong social ties and close friendship networks in both the using and dealing of drugs. Patterns of drug transaction and consumption are compared among the subjects, and the implications of these findings are discussed.
