The attitudes and life-style characteristics of 58 undergraduate nonusers of illegal drugs were evaluated through comparisons with 47 regular marijuana users. The nonusers were found to be more settled in their values, more goal-directed, and more involved academically. They also had higher Grade Point Averages. The nonusers appeared to be both knowledgeable and tolerant of marijuana use but to feel no need for its effects themselves. Statistics comparing the users and nonusers are presented on a number of other dimensions: (1) fraternity-sorority affiliation; (2) political attitudes; (3) satisfaction with the university; (4) stability of family; (5) religious preference; (6) involvement in work and extracurricular activities; (7) future career plans; (8) knowledge of sources of illegal drugs; (9) alcohol use; (10) attitude toward legalization of marijuana; and (11) attitudes toward LSD. It was concluded that nonusers share the traditional goals of working and studying hard to get ahead. (Author/BW)
