Abstract
In this article, we present findings from a qualitative National Institute on Drug Abuse-funded study of nonmedical prescription drug users in the San Francisco Bay Area. We interviewed young adults between the ages of 18 and 25 years, who used prescription drugs nonmedically at least 12 times in the 6 months prior to the interview. Employing Aker's Social Learning Theory and Zinberg's Drug, Set, and Setting, we explore the factors that contributed to participants' choices to begin using prescription drugs nonmedically. Social Learning Theory provides the framework for understanding how deviant behaviors are learned and imitated, while set and setting emphasizes the psychological and social contexts of initiation and the ways in which the set and setting of the initiating user were influenced by exposure, motivation, access, and setting. Together, social learning, and set and setting allow us to understand the interaction of individual and social factors contributing to nonmedical prescription drug use initiation.
