SAMHSA has partnered with the National Center for Health Statistics (NCHS) to host restricted-use National Survey on Drug Use and Health (NSDUH) data at their Federal Statistical Research Data Centers (RDCs). RDCs are secure facilities that provide access to a range of restricted-use microdata for statistical purposes. SAMHSA is the most recent federal partner to work with NCHS in making NSDUH restricted-use microdata available to approved researchers at RDC sites.


The 2016 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.


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.
