This chapter highlights important findings in the 2011 TEDS data. The tables include items in the TEDS Minimum and Supplemental Data Sets for 2011. (See Appendix B for a complete data dictionary.) Data are tabulated as percentage distributions of treatment admissions according to primary substance of abuse. It is important to note that percentages in charts, narrative lists, and percentage distributions in tables may not add to 100 percent due to rounding.
The Minimum Data Set consists of 19 items that include:
- Demographic information
- Primary, secondary, and tertiary substances and their route of administration, frequency of use, and age at first use
- Source of referral to treatment
- Number of prior treatment episodes
- Service type, including medication-assisted opioid therapy
The Supplemental Data Set consists of 17 items that include psychiatric, social, and economic
measures.
Not all States report all data items in the Minimum and Supplemental Data Sets. Most States report the Minimum Data Set for all or nearly all TEDS admissions. However, the items reported from the Supplemental Data Set vary greatly across States.
The figures in this chapter represent counts of admissions for each primary substance of abuse by gender, age, and race/ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic of Mexican
origin, Hispanic of Puerto Rican origin,1 American Indian/Alaska Native, and Asian/Pacific
Islander).

- Blacks made up 20 percent of all admissions (14 percent males and 6 percent females) [Table 2.3a].
- Forty-one percent of treatment admissions had not been in treatment before the current episode, while 13 percent had been in treatment five or more times previously [Table 2.5].
- Most admissions (62 percent) received ambulatory treatment, 1 in 5 (21 percent) received
detoxification, and 17 percent received rehabilitation/residential treatment [Table 2.7].
- Self- or individual referrals and the criminal justice system were responsible for 35 percent and 34 percent, respectively, of referrals to treatment [Table 2.6].
