TEDS data show that Hispanic female admission for substance-abuse treatment were less likely than non-Hispanic females to report primary alcohol abuse (23 percent compared to 32 percent), and they were more likely to report primary opiate abuse (21 percent compared to 19 percent). Female admissions of Mexican origin were younger than female admissions of Puerto Rican, Cuban, or "other Hispanic" origin for the primary substances of alcohol, cocaine, and marijuana. Hispanic female admissions were more likely than non-Hispanic female admissions to be younger than 18 years old (14 percent compared to 7 percent) and less likely to be 45 years old or older (12 percent compared to 18 percent). The TEDS is an annual compilation of data on the demographic characteristics and substance-abuse problems of those admitted to substance abuse treatment, primarily at facilities that receive some public funding. TEDS records represent admissions rather than individuals, since a person may be admitted to treatment more than once during a single year. 3 figures, 1 table, and 7 notes
