Sensation seeking, attitudes toward drug use, and actual use among adolescents: testing a model for alcohol and ecstacy use.

The use of ecstasy (MDMA), one of the most popular substances among young people in the context of many leisure and fun activities, is moving from party and recreation circuits to high schools and college dorms, in many cases in combination with alcohol consumption. Bearing in mind the concurrent use of the two drugs and the "gateway" thesis of a progression from legal drugs to illegal ones, a causal(1) model of linkages among sensation seeking, attitudes toward alcohol and ecstasy consumption, and frequency of use was tested using structural equation modeling (SEM). The data were obtained from a sample of 450 high school students ranging in age from 14 to 18 (47% male, 53% female).
