Five substances accounted for 95 percent of all TEDS admissions in 2005: alcohol (39 percent), opiates (17 percent), marijuana/hashish (16 percent), cocaine (14 percent), and stimulants (9 percent, primarily methamphetamine). Data on admissions for each type of primary drug address secondary drug use and demographic information on gender, race, and age. Data on type of treatment services received indicate that 62 percent of TEDS admissions in 2005 entered ambulatory treatment, 21 percent entered detoxification, and 17 percent entered residential/rehabilitation treatment. Opioid replacement therapy (medication-assisted therapy with methadone or buprenorphine) was planned for 6 percent of admissions in 2005. Thirty-six percent of TEDS admissions were referred to treatment through the criminal justice system; 34 percent of admissions involved self- or individual referrals. In 2005, 29 percent of admissions aged 16 and over were employed, and 32 percent were unemployed; 40 percent of admissions were not in the labor force, i.e., they were disabled, students, inmates of institutions, homemakers, retired, or were not looking for work during the past 30 days. Twenty-seven percent of admissions aged 18 and over had from 9 to 11 years of education; 44 percent of admissions ages 18 and over had 12 years of education; and 22 percent had more than 12 years of education. 6 tables and appended TEDS minimum dataset
