According to the survey, over 82 percent of the respondents had used at least one substance; over 80 percent had used alcohol and nearly 39 percent an illicit drug. The most commonly used illicit drugs were marijuana, glue, inhalants, hallucinogens, and amphetamines. Most respondents had begun their substance use before entering 10th grade. Far fewer students reported using any substance within the 30 days prior to this survey and only 11 percent reported regular use (on 10 or more occasions within the past 30 days) of any substance. Lifetime use of one or more substances continued to decline in 1992, however there was evidence that the long-term downward trend was reversing itself and student attitudes toward drugs seemed to be less negative.
