Information provided in the introduction included the names of the survey sponsors, the purpose of the study, the survey instructions, and statements that participation in the study was voluntary and anonymous. Therefore, a design weight, which is the inverse of the number of classes for which the respondent is enrolled, was created to adjust for class enrollment. In addition, weights based on the age, race, and sex distribution of the UMCP campus population were applied so that the age, race, and sex distribution of the survey sample would match that of the UMCP student population. All the results presented in this report are based on weighted data. Although the survey was anonymous, some students may have misreported their drug use behaviors.
Alcohol is the most widely used substance.
Seventy-nine percent, or an estimated 25,700 UMCP students, reported alcohol use at least once in the year prior to the survey. Sixty-six percent, or an estimated 21,200 students, reported alcohol use at least once in the month prior to the survey. Marijuana is the most widely used illicit substance. Inhalants are the third most widely used substance. The majority of students at each class level have used alcohol.
