Highlights
This report presents State estimates for 25 measures of substance use and mental health based on the combined 2009 and 2010 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 135,811 persons were collected in 2009-2010 (see Table A.9 in Appendix A). With the exception of the four mental health measures, separate estimates are presented for each measure 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 measures are not included in this report, they are available at http://www.samhsa.gov/data/NSDUH/2k10State/NSDUHsae2010/Index.aspx. 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 2009-2010, Chapters 2 to 6 provide comparisons of the 2008-2009 estimates with the 2009-2010 estimates for all measures and indicate whether the differences between the two are statistically significant.2 Increases or decreases are discussed only if they are statistically significant at the 0.05 level. Tables showing comparisons between 2002-2003 and 2009-2010 State estimates will be available on the SAMHSA Web site at http://www.samhsa.gov/data/NSDUH/2k10State/NSDUHsae2010/Index.aspx.
Illicit Drug Use
- In 2009-2010, 8.8 percent of the U.S. population aged 12 or older used an illicit drug in the past month, which was higher than the rate in 2008-2009 (8.4 percent). Past month use of illicit drugs among persons aged 12 or older ranged from 5.3 percent in North Dakota to 14.2 percent in Alaska. Between 2008-2009 and 2009-2010, rates of past month illicit drug use among persons aged 12 or older increased in eight States (Colorado, District of Columbia, Idaho, Maryland, Michigan, Texas, Virginia, and Washington). Only Hawaii's rate decreased. (Tables B.1 and C.1)
- In 2009-2010, past month marijuana use was reported by 6.8 percent of the U.S. population aged 12 years or older, an increase from 6.4 percent in 2008-2009. This rate ranged from 3.1 percent in Utah to 11.8 percent in Alaska. Utah had the lowest rate across all age groups presented. Seven States were ranked in the top fifth for past month marijuana use in age groups 12 to 17, 18 to 25, 26 or older, and 12 or older: Colorado, Maine, Massachusetts, New Hampshire, Oregon, Rhode Island, and Vermont. Between 2008-2009 and 2009-2010, past month marijuana use among persons aged 12 or older increased in 10 States: Colorado, District of Columbia, Idaho, Illinois, Massachusetts, Michigan, New Mexico, Oklahoma, Texas, and Washington. Only Tennessee's rate decreased in the 12 or older age group. (Tables B.3 and C.3; Figures 2.9 to 2.12)
- In 2009-2010, the rate of perceived great risk of marijuana use once a month among persons 12 or older was 33.6 percent nationwide and ranged from 22.3 percent in Colorado to 45.2 percent in Mississippi. Between 2008-2009 and 2009-2010, the national percentage of persons aged 12 or older perceiving a great risk of smoking marijuana once a month decreased from 35.8 to 33.6 percent. Decreases in the national rates occurred in every age group, including among persons aged 12 to 17 (from 31.8 to 29.9 percent). Twenty States showed decreases in the perceived great risk of smoking marijuana once a month among persons aged 12 or older. Decreases occurred in 16 States among youths aged 12 to 17, 22 States among persons aged 18 to 25, and 15 States among persons aged 26 or older. No increases were observed in any State or age group. Among youths aged 12 to 17, 7 of the 10 States that ranked in the highest fifth for past month marijuana use also ranked in the lowest fifth for perceived great risk of smoking marijuana once a month (Colorado, District of Columbia, Massachusetts, New Hampshire, Oregon, Rhode Island, and Vermont). (Tables B.4 and C.4; Figures 2.10 and 2.14)
- In 2009-2010, the national prevalence of past year cocaine use among persons aged 12 or older was 1.9 percent, which was a decline from 2.0 percent in 2008-2009.

In this time period, rates of use among persons aged 12 or older ranged from 26.4 percent in Utah to 64.1 percent in Wisconsin. Among persons aged 12 or older, 8 of the 10 States that were ranked in the bottom fifth for current use were from the South (Alabama, Arkansas, Kentucky, Louisiana, Mississippi, South Carolina, Tennessee, and West Virginia). Arizona was the only State with a decrease among persons aged 12 or older from 2008-2009 to 2009-2010 (from 51.2 to 48.1 percent). (Tables B.9 and C.9; Figure 3.1)

Two States showed decreases in binge drinking between 2008-2009 and 2009-2010 among persons 12 or older: Florida (from 21.9 to 20.7 percent) and Ohio (from 25.3 to 23.6 percent).

End Notes
1 For the purposes of this report, the word "States" includes the 50 States and the District of Columbia.
2 During regular data collection and processing checks for the 2011 NSDUH, data errors were identified. These errors affected the data for Pennsylvania (2006-2010) and Maryland (2008-2009). Cases with erroneous data were removed from the data files, and the remaining cases were reweighted to provide representative estimates. Thus, the 2008-2009 small area estimates presented in this report may not match the 2008-2009 small area estimates in prior reports. For details, see Section 1.5 in Chapter 1.
