The 1990 National Household Survey on Drug Abuse
The 1990 National Household Survey on Drug Abuse (NHSDA) is the tenth in a series of cross-sectional studies, which began in 1971, designed to measure the prevalence and correlates of drug use in the United States household population aged 12 and over. The 1990 NHSDA was sponsored by the National Institute on Drug Abuse (NIDA) and directed by researchers from the Research Triangle Institute in Research Triangle Park, North Carolina. Interviewers administered question-naires in-person to a household probability sample of 9,259 respondents within the contig- uous 48 states. Topics covered in the 1990 NHSDA include tobacco, alcohol, and illicit drug use; consequences of various drugs; health condition; and general demographic infor-mation. This data set contains 1,006 variables.
