National Survey on Drug Use and Health (NSDUH)
The data provide estimates of substance use and mental illness at the national, state, and substate levels. NSDUH data also help to identify the extent of substance use and mental illness among different subgroups, estimate trends over time, and determine the need for treatment services.
The National Survey on Drug Use and Health (NSDUH), conducted annually by the Substance Abuse and Mental Health Services Administration (SAMHSA), provides nationally representative data on the use of tobacco, alcohol, and illicit drugs; substance use disorders; receipt of substance use treatment; mental health issues; and the use of mental health services among the civilian, noninstitutionalized population aged 12 or older in the United States. NSDUH estimates allow researchers, clinicians, policymakers, and the general public to better understand and improve the nation’s behavioral health.
Where Does Data Come From
Prior to 2020, NSDUH conducted face-to-face household interviews. Starting in 2020, NSDUH conducted both face-to-face household interviews and web-based interviews. NSDUH is representative of persons aged 12 and older in the civilian noninstitutionalized population of the United States and in each state and the District of Columbia. The survey covers residents of households (including those living in houses, townhouses, apartments, and condominiums), persons in noninstitutional group quarters (including those in shelters, boarding houses, college dormitories, migratory work camps, and halfway houses), and civilians living on military bases. Persons excluded from the survey include individuals experiencing homelessness who do not use shelters, active military personnel, and residents of institutional group quarters such as jails, nursing homes, mental institutions, and long-term care hospitals.
The Federal Government has conducted the survey since 1971. Over the years, the survey has undergone a series of changes. In 1999, the survey shifted from paper-and-pencil data collection to computer-assisted interviewing (CAI). With CAI, staff administer most questions with audio computer-assisted self-interviewing. This provides a confidential way to answer questions and encourages honest responses.
In 1999, the sample design expanded to include all 50 states and the District of Columbia. In 2002, the name of the survey changed from the National Household Survey on Drug Abuse to NSDUH. The survey also began including a $30 incentive for respondents. The most recent updates are changes in the sampling design (2014) and the questionnaire (2015). More information about the questionnaire changes can be found here.
