Data Hosting: National Survey on Drug Use and Health (NSDUH)
The National Survey on Drug Use and Health (NSDUH) measures:
- use of illegal drugs, prescription drugs, alcohol, and tobacco
- mental disorders, treatment, and co-occurring substance use and mental disorders
NSDUH data provides estimates of substance use and mental illness at the national, state, and sub-state levels. NSDUH data also helps to identify the extent of substance use and mental illness among different sub-groups, can be used for estimates of trends over time, and measures the need for treatment services
SAMHSA and NCHS have partnered to provide access to restricted-use NSDUH data through the NCHS RDC Network.
Non US citizens should contact the NCHS RDC, email@example.com, to inquire about additional access requirements.
Proposals are submitted to NCHS and SAMHSA reviews and approves all NSDUH proposals. Proposal review will take 12 weeks. Submit completed proposals to firstname.lastname@example.org.
Proposal amendments, including changes to the research team or minor adjustments to research questions, require an updated proposal and full review by SAMHSA. Revisions in the proposal must to be highlighted; please do not use track changes.

Guidelines for Using NSDUH Data:
The estimated cost of a RDC project is $3,000 but varies from project to project. The Federal Statistical RDC may apply additional fees.
Confidentiality and Disclosure:
After the proposal is approved, all members of the research team are required to complete the Confidentiality orientation and become designated agents. Please submit your confidentiality orientation certificates and signed SAMHSA Designated Agent form to your RDC Analyst.
