description: This series measures the prevalence and correlates of drug
use in the United States. The surveys are designed to provide
quarterly, as well as annual, estimates. Information is provided on
the use of illicit drugs, alcohol, anabolic steroids, and tobacco
among members of United States households aged 12 and older. Data are
also provided on treatment for drug use and on illegal activities
related to drug use. Questions include age at first use, as well as
lifetime, annual, and past-month usage for the following drug classes:
marijuana, inhalants, cocaine, hallucinogens, heroin, alcohol, tobacco,
and nonmedical use of psychotherapeutics. Respondents were also asked
about problems resulting from their use of drugs, alcohol, and
tobacco, their perceptions of the risks involved, insurance coverage,
and personal and family income sources and amounts. Demographic data
include gender, race, ethnicity, educational level, job status, income
level, household composition, and population density.
description: Data were weighted based on the
three stages of sampling that were used. Adjustments were made to compensate for nonresponse and
sampling error. Adjustments also included trimming sample weights to
reduce excessive weight variation and a post-stratification to Census
population estimates. The final weight variable to be used in analysis is ANALWT.
description: Response Rates: Strategies for ensuring high rates of participation resulted in
an interview response rate of 84.2 percent. Of the 32,594 completed
interviews, 16,628 were with Whites and other (i.e., non-Hispanic,
non-Blacks), 8,050 were with (non-Hispanic) Blacks, and 7,916 were
with Hispanics. Approximately 7 percent (2,190) of the interviews were
conducted using the Spanish version of the questionnaire. The
completed interviews represented a 96.5 percent completion rate for
screening sample households and an 84.2 percent for interviewing sample
individuals. The response rates for these three racial/ethnic groups
were 82.3 percent for Whites and others, 85.1 percent for Blacks, and 87.3 percent for
Hispanics.

Metropolitan Statistical Areas of special interest: Washington, DC,
New York City, Miami, Chicago, Denver, and Los Angeles. Minorities and
youths aged 12-17 were also oversampled.

description: Data were collected by Research Triangle
Institute, Research Triangle Park, NC, and prepared for release by
National Opinion Research Center, Chicago, IL.For selected
variables, statistical imputation was performed following logical
imputation to replace missing responses. Unique code values (7, 8, or
9) were assigned to the recency-of-use variable when such logical
imputation occurred. These code values are readily identifiable by the
phrase "... LOGICALLY IMPUTED" in the code value descriptions. For
those recency-of-use variables with missing data for which no
indication of use of the drug could be found by examination of all
relevant variables in the record, a code value of 91 ("Never Used")
was assigned if there were one or more indications of such nonuse in
the set of relevant variables.To protect the anonymity of respondents, all
variables that could be used to identify individuals have been deleted
from the public use file.For some drugs that have multiple names, questions regarding the use of that drug may be asked for each distinct name. For example, even though methamphetamine, methedrine and desoxyn are the same drug, their use was measured in three separate variables.
