Voluntary reduction of cannabis use among graduate students

Conceptualizing drug use within stages of drug career, this study explored differences between former and current regular marijuana users and the factors associated with reduction of their marijuana use. A total population of 2,983 graduate students were surveyed with a purposive sampling technique resulting in interviews with 186 study subjects. While no attribute variables were predictive of reduction or discontinuance, the frequency of substitution of other activities significantly differed among groups. The implications of these results are discussed within the context of alternative life-style changes in the marijuana careers of study subjects.
