NHSDA 1991

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.

  1. Data were collected by Research Triangle Institute, Research Triangle Park, NC, and prepared for release by National Opinion Research Center, Chicago, IL.

  2. 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.

  3. To protect the anonymity of respondents, all variables that could be used to identify individuals have been deleted from the public use file.

  4. 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.


Multistage area sample design with oversampling of six 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.

The noninstitutionalized civilian population of the United States, aged 12 and older.


personal interviews, including self-enumerated answer sheets for questions on drugs

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.

2015-11-23 Covers for the PDF documentation were revised.

2015-02-03 Created a separate Questionnaire PDF that was extracted from the Codebook PDF.

2013-06-20 Updating xml file to include variable headings and subheadings.

2008-08-05 New files were added. These files included one or more of the following: Stata setup, SAS transport (CPORT), SPSS system, Stata system, SAS supplemental syntax, and Stata supplemental syntax files, and tab-delimited ASCII data file. The variable CASEID was also added to the dataset.

1999-05-12 SAS and SPSS data definition statements have been updated to include value labels and missing values sections, and the appendices have been added to the PDF codebook.

1993-10-11 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Performed consistency checks.
  • Standardized missing values.
  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.

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.



  • The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.
