Check out the tools SAMHDA has available that allow you to directly analyze our data.
Do you want to see how prevalent mental health and substance use issues are in your area? The National Survey on Drug Use and Health (NSDUH) Small Area Estimates is a tool that allows you to compare variables between states or substate regions, look at changes over time, or compare related issues. Download and share the results in PDF or CSV file format.
Data Analysis Systems
Explore outcomes across different variables to examine associations between them using the Public-Use and Restricted-Use Data Analysis Systems (PDAS and RDAS). These systems provide a convenient means of exploring SAMHSA data from several data sources without having to download any dataset files or additional tools. Use PDAS to explore the review study variables, run crosstab analyses, and download the results of analysis as a PNG image or as a data file in CSV format. Use RDAS to explore results over multiple survey years or year-pairs, including surveys with location-based information. If you’re not sure where to start, check out the video tutorials in our Get Help section.
The Quick Statistics tool allows you to quickly find a data table from our Treatment Episode Data Set (TEDS), National Survey of Substance Abuse Treatment Services (N-SSATS), or National Mental Health Services Survey (N-MHSS) information. The data are updated quarterly. Each data table is provided either as an HTML page or as a PDF.
Research Data Centers
SAMHSA has partnered with the National Center for Health Statistics (NCHS) to host restricted-use NSDUH data at its 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. Eligible researchers may now apply for access to these data through SAMHSA's RDC website.
