The High School Survey on Drugs was developed to assess the drug attitudes of and usage by high school students. The survey was designed to determine drug usage in a specific geopolitical area and to determine drug education program needs. The questionnaire is easily administered to groups of students. There are three types of questions associated with each of thirteen classes of drugs--prevalence, frequency of usage, and perception of harmfulness. The instrument is designed to assess group, rather than individual status. The 72 item instrument is included in the document. (DWH)
