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, tobacco, and nonmedical use of prescription drugs among members of United States households aged 12 and older. Questions include age at first use, as well as lifetime, annual, and past-month usage for the following drug classes: cannabis, cocaine, hallucinogens, heroin, alcohol, tobacco, and nonmedical use of prescription drugs, including psychotherapeutics. Respondents were also asked about problems resulting from their use of drugs, alcohol, and tobacco, their perceptions of the risks involved, and personal and family income sources and amounts. Half of the respondents were asked questions regarding substance use by close friends. Demographic data include gender, race, age, ethnicity, educational level, job status, income level, veteran status, household composition, and population density. Youth respondents were also asked about time spent on homework and leisure activities.

Multistage area probability sample design involving five selection stages: (a) primary areas (e.g., counties), (b) subareas within primary areas (geographic area of approximately 2,500 population in 1970), (c) housing units within subareas, (d) age group domains within listed units, and (e) members of households within sampled age groups. The two race classifications were: White, and Black/other. The three age groups were: youth (age 12 to 17), young adult (age 18 to 34), and older adult (age 35 and older). Each age group was sampled separately, and the probability of selection decreased with the prospective respondent's age. One youth and/or one adult could be chosen per household. The basic national sample was supplemented by a sample of residents of rural areas. The overall interview completion rate was 81 percent. 1981 1981 1982 1982

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.
Created online analysis version with question text.
Checked for undocumented or out-of-range codes.

The interview completion rates for the three age groups were: 84 percent for youth, 81 percent for young adults, and 77 percent for older adults. ICPSR

National Institute on Drug Abuse 2008-06-18 ICPSR 2008-06-18 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. Also added variable CASEID to the dataset. 1999-05-12 ICPSR 1999-05-12 SAS and SPSS data definition statements have been updated to include value labels and missing values sections. StudyUnit06845

Data were collected by Response Analysis Corporation, Princeton, NJ, under contract with the National Institute on Drug Abuse. The data and codebook were prepared for release by Research Triangle Institute, Research Triangle Park, NC, and the codebook was initially distributed by National Opinion Research Center, Chicago, IL, under contracts with the Substance Abuse and Mental Health Services Administration.

For selected variables, statistical imputation was done following logical imputation to replace missing responses. These variables are identified by the designation "IMPUTATION-REVISED" in the variable label, and the names of these variables begin with the letters "IR". For each imputation-revised variable there is a corresponding imputation indicator variable that indicates whether a case's value on the variable resulted from an interview response, logical imputation, or statistical imputation. The names of imputation indicator variables begin with the letters "II".

Data were weighted based on two weight factors required in the sampling plan. The product of the sampling weight factors is equal to the inverse of each respondent's selection probability. Adjustments were made to compensate for nonresponse and sampling error. Adjustments also included a poststratification to Census population estimates.

To protect the confidentiality of respondents, all variables that could be used to identify individuals have been encrypted or collapsed in the public use file. These modifications should not affect analytic uses of the public use file.

Some frequencies related to interview information detailed on page 79 of the codebook (FINLRES1, VSADLTCM, PHADLTCM, VSYTHCM, PHYTHCM) reflect overlapping records. For example, although "Adult/Youth" (ADULTYTH) indicates that 4,043 adults were interviewed, "Final Adult Result" (FINLRES1) indicates that an adult interview was completed in 4,706 cases. Crosstabulation of these variables revealed that adult interviews were completed in 663 youth cases. This apparently represents households in which both an adult and a youth were interviewed.

For some drugs that have multiple names, questions regarding the use of that drug may be asked for each distinct name. For example, the use of methedrine and desoxyn are measured separately in this study even though they are both methamphetamine.
