2002 State Estimates of Substance Use


This report is the first presenting State estimates from the 2002 National Survey on Drug Use and Health (NSDUH), 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, NSDUH collected interview data from approximately 68,000 respondents. Estimates for all persons aged 12 or older are provided for 20 different measures related to substance use or mental health. For each measure, States have been ranked and categorized into quintiles, or fifths, in order to simplify the discussion.

Methodological changes introduced in 2002 affected respondent participation rates and response patterns, resulting in changes in prevalence estimates. Therefore, the findings from the 2002 NSDUH should not be compared with results from the 2001 or earlier NHSDAs. The 2002 survey represents a new baseline for the State estimates as well as for the national estimates.
