This report presents State estimates for 25 measures of substance use and mental health based on the 2008 and 2009 National Surveys on Drug Use and Health (NSDUHs). Sponsored by the Substance Abuse and Mental Health Services Administration (SAMHSA), NSDUH is an ongoing survey of the civilian, noninstitutionalized population of the United States aged 12 years or older. Interview data from 137,436 persons were collected in 2008-2009 (see Table A.9 in Appendix A). With the exception of the four mental health outcomes, separate estimates are presented for each outcome in four age groups: 12 to 17, 18 to 25, 26 or older, and all persons 12 or older. For past year serious mental illness, past year any mental illness, past year suicidal thoughts, and past year major depressive episode (i.e., depression), estimates are available for adults in three age groups: 18 to 25, 26 or older, and 18 or older. In addition, estimates for major depressive episode are available for youths aged 12 to 17. This report also includes estimates for persons aged 12 to 20 for two of the measures—past month alcohol use and past month binge alcohol use, representing underage use of alcohol. Although estimates for persons aged 18 or older for the substance use outcomes are not included in this report, they are available at http://www.samhsa.gov/data/states.htm. Additionally, tables showing the total number of persons associated with each measure are available at this Web site.

For each measure, States have been ranked and categorized into quintiles, or fifths, in order to simplify the discussion.1 Estimates presented in this report are based on a hierarchical Bayes estimation method that combines survey data with a national model. Note that these estimates are benchmarked to the national design-based estimates (for details, see Section A.6 in Appendix A). In addition to presenting State estimates for 2008-2009, Chapters 2 to 6 provide comparisons of the 2007-2008 estimates with the 2008-2009 estimates for all outcomes and indicate whether the differences between the two are statistically significant. Increases or decreases are discussed only if they are statistically significant at the 0.05 level. Chapter 7 compares estimates between 2002-2003 and 2008-2009 for a select set of outcomes.
