Sample survey: in-person interviews plus audio computer-assisted self-administered interviews for sensitive items.
The National Survey on Drug Use and Health (NSDUH) 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, noninstitutionalized population ages 12 years and older. The survey also includes several series of questions focusing on mental health issues. The NSDUH collects data through face-to-face interviews with a representative sample of the population at the respondent's place of residence, including households and non-institutional group quarters (e.g., shelters, rooming houses, dormitories). The survey excludes homeless people who do not use shelters, military personnel on active duty, and residents of institutional group quarters, such as jails and hospitals.
