A survey of substances use among junior and senior high school students in New York state, Winter 1974-75.

A survey designed to assess drug and alcohol use among the 1,600,000 students in Grades 7 through 12 who attend New York State public schools was administered in 10i schools during the winter of 1974-75. Findings indicate that over 80% of the students have used alcohol and that almost one-third of the students have used marijuana at least once. In addition, 60% of the marijuana users have used no other substance, with the possible exception of alcohol. Also, if a student has used a substance, he is likely to have used it within the last 6 months. Finally, multiple substance use is not predominant among marijuana users, but is predominant among users of other substances.
