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 these and other drugs.

Eligible Sample

Participants aged 12-69 years were eligible; however, only data from participants aged 18-69 are included in this file for public release. Data collected for participants aged 12-17 years are available through the NCHS Research Data Center (RDC). Mentally impaired participants, or participants who were unable to understand English, Spanish, Korean, Vietnamese, or Chinese (traditional/Mandarin, simplified/Mandarin, and traditional/Cantonese) were excluded from the DUQ.

Interview Setting and Mode of Administration

The DUQ was administered at the Mobile Examination Center (MEC) during the MEC Interview. For participants aged 12 to 69, questions were self-administered using the Audio Computer-Assisted Self-Interview (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 participants both to hear questions through headphones and read questions on the computer screen. Participants moved at their own speed and touched the screen to indicate their responses. No proxy respondents or translators were used during the ACASI.

Quality Assurance & Quality Control

For details on the QA/QC process for this component, please refer to the MEC Interviewer Procedures manual on the NHANES website.

Data Processing and Editing

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

To decrease the risk of disclosure, additional “bottom” summary codes were implemented for six variables in 2017-2018. For the age of first use variables (DUQ210, DUQ213, DUQ260, DUQ300, DUQ340, DUQ390), participants who reported an age less than or equal to 11 years were coded as “11 years or younger.”

In addition, the new variable DUD380F includes participants who reported injecting steroids or “any other drug” (i.e., other than cocaine, heroin, or methamphetamine, which are asked about separately) using a needle. In prior cycles, these frequencies were available separately in variables DUQ380D and DUQ380E, respectively. 

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 are included in this data file. A special use data file for participants aged 12-17, DUQY_J_R, is available through the NCHS Research Data Center (RDC).
