Component Description

The drug use (DUQ) questions focus on lifetime and current use of marijuana or hashish, cocaine, heroin, and methamphetamine, as well as intravenous use of drugs.

Eligible Sample

Participants aged 12-69 years were eligible. Mentally impaired individuals, or participants who were unable to understand English, Spanish, Korean, Vietnamese, or Chinese (traditional/mandarin, simplified/mandarin, and traditional/Cantonese) were not asked these questions. Only data from participants aged 18-69 years are included in this data file.

Interview Setting and Mode of Administration

The Drug Use questionnaire was administered at the Mobile Examination Center (MEC) during the MEC Interview. For adults 18 years and older, questions were self-administered using the Audio Computer-Assisted Self-Interviewing (ACASI) system.

The ACASI was conducted in one of the following languages: English, Spanish, Korean, Vietnamese, or Chinese (traditional/mandarin, simplified/mandarin, and traditional/Cantonese).

Quality Assurance & Quality Control

The ACASI enables respondents both to hear questions through earphones and read questions on the computer screen. Respondents moved at their own speed and touched the screen to indicate their response. No proxy respondents or translators were used in situations when the respondents could not self-report. The system was programmed to alert respondents of potential data entry errors or problems. When a response was entered, that had been programmed as unlikely, respondents were allowed to proceed after confirming that their entry was correct. When a response was entered that had been programmed as an error, respondents were prohibited from continuing with the ACASI until the error was corrected.

Data Processing and Editing

The data were edited for completeness, consistency, and illogical values.

Analytic Notes

Please refer to the NHANES Analytic Guidelines and the on-line NHANES Tutorial for further details on the use of sample weights and other analytic issues.


Information on drug use is collected from all participants aged 12-69 years. Only data from participants aged 18-69 years are included in this data file. A special use data file for participants 12-17 years, DUQ_G_R, is available through the  NCHS Research Data Center (RDC).
