National Survey on Drug Use and Health

National Survey on Drug Use and Health (NSDUH), an annual survey of the civilian, non-institutionalized population of the United States aged 12 years or older, is the primary source of statistical information on the use of tobacco, alcohol, prescription psychotherapeutic drugs (pain relievers, tranquilizers, stimulants, and sedatives), and other substances (e.g., marijuana, cocaine) by the U.S. civilian, non-institutionalized population aged 12 years or older. The survey also includes several series of questions focusing on mental health issues.
