Component Description

The drug use questionnaire (variable name prefix DUQ) focuses 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 12-17 years old are included in this file with limited access.

Interview Setting and Mode of Administration

The Drug Use questionnaire was administered at the Mobile Examination Center (MEC) during the MEC Interview. For Youths 12-17 years, 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). The ACASI enables respondents to hear questions through earphones as well as 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.

Mentally impaired individuals or participants who were unable to understand English or Spanish were not asked these questions.

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 years and older. Only data from participants aged 12-17 years old are included in this file with limited access. Data from participants aged 18 years and older are publicly released and available on the NHANES website.
