Information about SAMHDA restricted-use and public-use data

As of August 21, 2015, the Substance Abuse and Mental Health Services Administration (SAMHSA) contracted with a different vendor to distribute the restricted-use data from the National Survey on Drug Use and Health (NSDUH), restricted-use data from the Drug Abuse Warning Network (DAWN), and other SAMHDA restricted-use data. Questions about SAMHSA restricted-use data should be sent to samhda-support@samhsa.hhs.gov.

ICPSR continues to distribute public-use files created by the SAMHDA project as well as providing access to over 1,200 restricted-use data collections, including through the popular and high-quality ICPSR Virtual Data Enclave (VDE).

Users interested in drug abuse data should search the NAHDAP catalog. Users also interested in mental health data should search the ICPSR catalog.

Online analysis versions of the SAMHDA public-use data are also available for all studies that had them available on the previous SAMHDA website.
