This chapter highlights important findings in the 2008 TEDS data. The tables include all items in the TEDS Minimum and Supplemental Data Sets for 2008. (See Appendix B for a complete data dictionary.) Data are tabulated as percentage distributions of treatment admissions according to primary substance of abuse.
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 15 items that include psychiatric, social, and economic
measures.
Definitions and classifications used in the Minimum and Supplemental Data Sets are detailed in
Appendix B.
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,2 and Asian/Pacific
Islander).

- Forty-three percent of treatment admissions had not been in treatment before the current episode, while 12 percent had been in treatment five or more times previously [Table 2.5].
