The Substance Abuse and Mental Health Data Archive (SAMHDA) is an initiative funded under contract HHSS283201500001C with the Center for Behavioral Health Statistics and Quality (CBHSQ), Substance Abuse and Mental Health Services Administration (SAMHSA), U.S. Department of Health and Human Services (HHS). CBHSQ has primary responsibility for the collection, analysis, and dissemination of SAMHSA's behavioral health data. Public use files and restricted use files are provided.
CBHSQ promotes the access and use of the nation's substance abuse and mental health data through SAMHDA. SAMHDA provides public-use data files, file documentation, and access to restricted-use data files to support a better understanding of this critical area of public health.
SAHMDA was one of the core partners of Inter-University Consortium for Political and Social Research (ICPSR)re3data100010255 . As of August 21, 2015 SAMHSA contracted with a different vendor to distribute NSDUH, DAWN, and other SAMHDA restricted-use data. Questions about SAMHSA restricted-use data should be sent to email@example.com. ICPSR will continue to distribute public-use files created by the SAMHDA project. Users interested in substance abuse data are encouraged to search the ICPSR catalog and to visit the National Addiction & HIV Data Archive Program. See http://www.icpsr.umich.edu/icpsrweb/SAMHDA/
