An ad hoc committee assessed the level and type of drug usage on the Middle Tennessee State University campus. The sample of almost 1600 undergraduates was consistent with the total student body profile. Greek membership tended to depress drug usage but to increase alcohol consumption, particularly for males. Students who lived off-campus were more likely to use drugs and alcohol and tended not to show sex differences in usage. On-campus students and students living at home shared more traditional behaviors. Freshmen were more likely to smoke marijuana, and seniors were more likely to smoke tobacco. Tocacco smoking showed no sex differences, but males were more likely than females to smoke marijuana. Males were more likely to have driven--or been arrested--after drug or alcohol usage. The school studied is religiously conservative with the majority of students from small towns and rural areas, which may cause some variance with other universities. The instrument, however, could be used in studying other campuses. Drug and alcohol usage at MTSU does not appear to be a significant factor in students' lives. (Author/LS)
