The National Survey on Drug Use and Health (NSDUH), is an ongoing survey of the civilian non-institutionalized population of the United States, ages 12 and over. Between 1979 and 1988, the survey was conducted every three years. Since 1990, the survey has been conducted annually. Fieldwork has been carried out by RTI, International since 1988. For the 1985 survey, fieldwork was conducted by the Temple University Institute for Survey Research, and the 1979 and 1982 surveys were conducted by Response Analysis Corporation, Princeton, NJ. The 1982 survey did not inquire about binge drinking or any proxies, and so is not included in these analyses.24, 26
