Welcome to the National Survey on Drug Use and Health (NSDUH)
A trusted source of data since 1971
What is NSDUH?
The National Survey on Drug Use and Health (NSDUH) provides up-to-date information on tobacco, alcohol, and drug use, mental health and other health-related issues 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 will be interviewed for this important study.
Information from NSDUH is used to support prevention and treatment programs, monitor substance use trends, estimate the need for treatment and inform public health policy.
Make a Difference
NSDUH is directed 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.
