Three hypotheses were tested: (1) drug education was positively related to the perceived value of drug education; (2) drug education was inversely related to interest in trying drugs; and (3) drug education was inversely related to drug use. The study sample included a nationally representative group of high school seniors. The analysis focused on the 9 years between 1976 and 1984, and approximately 30,000 seniors responded to the questionnaire. Drug education was measured in terms of drug education courses or lectures in school and any other drug education experiences. Findings revealed moderate support for the first hypothesis, less support for the second hypothesis, and hardly any support for the third hypothesis. Study limitations are noted in light of the less than encouraging results on drug- related attitudes and self-report drug use. 20 references and 16 tables
