Results from the 2015 National Survey on Drug Use and Health: Detailed Tables is a collection of tables presenting national estimates from the National Survey on Drug Use and Health (NSDUH). These tables present information on drug, alcohol, and tobacco use, as well as drug and alcohol dependence and abuse and treatment, and measures of mental health, such as major depressive episodes and serious mental illness. Measures of these behaviors and characteristics are presented by a variety of demographic, geographic, and other variables. The estimates in the tables include rates of the behaviors, numbers of persons engaging in these behaviors, and other measures. Although the majority of these tables are trend tables presenting estimates from the 2014 and 2015 NSDUHs, some tables include only estimates from the 2015 NSDUH.
