The data were gathered in March and April 1989 using the Primary Prevention Awareness, Attitude and Usage Scales. Results showed that almost half the 12th graders and 8 percent of the 6th graders drink alcohol at least once a month. Twenty-one percent of the seniors and 13 percent of the ninth graders smoke cigarettes daily, while 14 percent of the seniors and 7 percent of the ninth graders smoke marijuana at least once a month. Of the seniors who drink regularly, 27 percent drive under the influence of alcohol at least once a month. Substances are used most often at parties, a friend's house, and home. Friends, youth who are out of school, and adults are the main sources of substances. Almost 40 percent of the seniors get drunk at least once a month. The four reasons most often given by students for not using substances are having close friends who accept them as they are, being self-confident, not disappointing family members, and knowing the effects of substances.
