SAMHSA recently released the results from the 2012 National Survey on Drug Use and Health (NSDUH), an annual survey of the civilian, non-institutionalized population of the United States, ages 12 or older.  Survey results present national estimates of rates of use, numbers of users, and other measures related to illicit drugs, alcohol, and tobacco products, with a focus on trends between 2011 and 2012, and from 2002 to 2012, as well as differences across population subgroups in 2012. NSDUH national estimates on mental health and state-level estimates on substance use and mental health will be available later this fall.
