Table 5.1 and Figure 27. The number of adolescents (aged 12-17) admitted to substance abuse treatment rose 45 percent between 1993 and 1998. Admissions for marijuana abuse grew from 32 percent of adolescent admissions in 1993 to 57 percent in 1998, and accounted for most of the increase in adolescent admissions. While numbers were small, adolescent admissions for opiates and stimulants also increased substantially.
Tables 5.2a and 5.2b. Overall, 70 percent of adolescent admissions were male. However, this proportion was heavily influenced by marijuana admissions, where 76 percent were male. The male:female ratio was much closer for other substances. Almost half (47 percent) of adolescent admissions were through the criminal justice system. Seventeen percent were individual referrals, and 12 percent were referred through schools.
