State estimates for 15 measures of substance use and mental disorders based on the combined 2015 and 2016 National Surveys on Drug Use and Health (NSDUHs) are provided. The NSDUH is an annual survey of the civilian, noninstutionalized population of the United States aged 12 years or older. State and regional estimates are based on a small area estimation (SAE) methodology in which state-level NSDUH data are combined with county and census block group/tract-level data from the state.


May is Mental Health Awareness Month 2017, and the Substance Abuse and Mental Health Data Archive (SAMHDA) provides several key resources and tools for behavioral health researchers.

SAMHDA offers public-use data files (PUFs) to assist researchers in this critical area of public health. Visit http://datafiles.samhsa.gov/ for more information.


The tool was updated with enhancements to the usability and functionality, including the NSDUH Small Area Estimates data with mapping and visualization tools and an enhanced user interface. See the Release Notes for more information on the enhancements.


The 2015 National Survey on Drug Use and Health (NSDUH) public use file is the latest in the NSDUH series. NSDUH is the primary source of statistical information on the use of tobacco, alcohol, prescription drugs, and illicit drugs by the U.S. civilian, noninstitutionalized population aged 12 or older. The survey also includes several series of questions that focus on mental health issues. In 2015, the NSDUH underwent a partial redesign to improve the quality of the data collected and to address current substance use and mental health policy and research needs.
