ADOLESCENT MARIJUANA AND ALCOHOL USE

Abstract
Most tests of differential association theory focus on the basic relationships rather than the causal process specified by the theory. This study provides a more thorough test of Sutherland's differential association hypothesis by deriving and testing a causal model of alcohol and marijuana use among adolescents. The findings provide strong support for the causal process specified by differential association theory. However, two unexpected findings suggest that the theory may have to be modified to account for the differential impact of peer pressure, independent of internalized definitions, on individual behavior and for the differential impact of specific primary groups on the formation of individual definitions.
