Substance Abuse and Mental Health Services Administration (SAMHSA) Restricted Use Data

With an aim to increase equitable access, quality, and responsiveness of restricted use data requests, SAMHSA is reconfiguring operations effective October 1, 2021. All the resources you need are now in one central location.

Interact Our data

We have created two interactive tools that allow you to quickly filter down to the datapoints you need. The NSDUH SAE tool allows you to quickly see data by state and substate areas. The Quick Statistics tool provides state profiles for TEDS, N-SSATS, and N-MHSS data.

Analyze Our data

We have two data analysis systems (PDAS for public use and the restricted-use RDAS) available for researchers. As part of PDAS, there is also a NSDUH SAE tool to quickly see data by state and substate areas.

Download Public Use Files

We make datasets available for public use in multiple formats: ASCII, SAS, SPSS, Stata, R, and TSV. Select a study series to go to the SAMHDA site to download files.
