2003 State Estimates of Substance Use


This report presents State estimates on substance use or mental illness problems from the combined 2002 and 2003 National Surveys on Drug Use and Health (NSDUHs), formerly called the National Household Survey on Drug Abuse (NHSDA). The survey, sponsored by the Substance Abuse and Mental Health Services Administration (SAMHSA), collects information from residents of households, residents of noninstitutionalized group quarters, and civilians living on military bases. In 2002 and 2003, NSDUH collected interview data from approximately 136,000 respondents. The report provides estimates for 21 different measures related to substance use or mental illness based on the pooled 2002 and 2003 NSDUH data. Separate estimates have been produced for four age groups: 12 to 17, 18 to 25, 26 or older, and all persons 12 or older. For each measure, States have been ranked and categorized into quintiles, or fifths, in order to simplify the discussion. Estimates presented in this report are based on hierarchical Bayes estimation methods that combine survey data with a national model.

Methodological changes introduced in 2002 affected respondent participation rates and response patterns, resulting in changes in prevalence estimates. Therefore, the findings from the 2002 and 2003 NSDUHs should not be compared with results from the 2001 or earlier NHSDAs. The 2002 survey represented a new baseline for the State estimates, as well as for the national estimates. By combining the 2002 and 2003 survey data, the State-level small area estimates have been improved. This report updates the State estimates of substance use from the 2002 NSDUH (Wright, 2004).
