2000 National Survey on Drug Use & Health


This report provides the first information obtained in the 2000 National Household Survey on Drug Abuse (NHSDA), a project of the Substance Abuse and Mental Health Services Administration (SAMHSA). Since 1971, the NHSDA has been the primary source of information on the prevalence and incidence of illicit drug, alcohol, and tobacco use in the civilian population aged 12 years and older.

Over the years improvements have been made to the Survey to provide better and more complete information on issues associated with substance abuse. In 1999, significant changes were made in the size of the survey, the sample design, and the method of administration. The sample size was expanded almost fourfold; data are now based on information obtained from approximately 70,000 persons per year. A new sample design was introduced which supports both national and state level estimates. A new, interactive, bilingual, computer-based questionnaire replaced the paper and pencil questionnaires used previously. These changes improved the accuracy of the estimates and the utility of the data. At the same time, the changes limit the comparisons that can be made with information obtained from surveys prior to 1999. Therefore, the report focuses only on recent trends, from 1999 to 2000.

This report provides national estimates of rates of use, number of users, initiation of use, and other measures related to use of illicit drugs, licit drugs that are used for non-medical purposes, alcohol, cigarettes, and other forms of tobacco by the population aged 12 years and older in 1999 and 2000. State-level estimates will be provided in a later report. Selected findings are given below:

Illicit Drug Use

Alcohol Use

Tobacco Use

Trends in Initiation of Substance Use (Incidence)

Trends in new use of substances are estimated using the data reported on age at first use from the 1999 and the 2000 NHSDA. Because information on when people first used a substance is collected on a retrospective basis, estimates of first time use or incidence are always one year behind estimates of current use.
