National Survey on Drug Use and Health (NSDUH)

Sponsor

The National Survey on Drug Use and Health (NSDUH) is sponsored by the U.S. Department of Health and Human Services, Substance Abuse and Mental Health Services Administration (SAMHSA), Center for Behavioral Health Statistics and Quality (CBHSQ). The CBHSQ (formerly the Office of Applied Studies (OAS)) is the data collection agency.

Description

The NSDUH serves as the primary source of information on the prevalence and incidence of illicit drug, alcohol, and tobacco use in the civilian, non-institutionalized population aged 12 or older in the United States. In-person interviews with sampled persons. Computer-assisted interviewing (CAI) methods, including audio computer-assisted self-interviewing (ACASI), are used to provide a private and confidential setting to complete the interview.

Survey Sample Design

The NSDUH covers residents of households (living in houses/townhouses, apartments, condominiums, etc.), persons in non-institutional group quarters (e.g., shelters, rooming/boarding houses, college dormitories, migratory workers' camps, halfway houses), and civilians living on military bases. Persons excluded from the survey include homeless people who do not use shelters, active military personnel, and residents of institutional group quarters.

NSDUH data are representative of the nation and states. The survey design includes an independent, multistage area probability sample for each state and the District of Columbia to accommodate state estimates of substance use and mental health. The survey design also oversamples youths and young adults.
