Illicit drug use rates remain highly correlated with educational status. Among young adults age 18-34 years old in 1995, those who had not completed high school had the highest rate of use (15.4 percent), while college graduates had the lowest rate of use (5.9 percent). This is despite the fact that young adults at different educational levels are equally as likely to have tried illicit drugs in their lifetime (50 percent of those not completing high school and 52 percent of college graduates).
