About the Survey
The National Survey on Drug Use and Health (NSDUH) provides national and state-level data on the use of tobacco, alcohol, illicit drugs (including the non-medical use of prescription drugs) and mental health in the United States.
NSDUH began in 1971 and is conducted every year in all 50 states and the District of Columbia. This year almost 70,000 people, ages 12 and older, will be interviewed for this important study.
Information from NSDUH is used to provide accurate data, track trends, assess consequences, and identify people at high risk for substance use and misuse.
NSDUH is administered by the Substance Abuse and Mental Health Services Administration (SAMHSA), an agency in the U.S. Department of Health and Human Services (DHHS).
The study is being conducted by RTI International, a nonprofit research organization based in Research Triangle Park, North Carolina. RTI has conducted the study since 1988.
