Date of Collection:
Unit of Observation:

and older, living in households.

Data were collected by Research Triangle
Institute, Research Triangle Park, NC, and prepared for release by
National Opinion Research Center, Chicago, IL.
variables, statistical imputation was performed following logical
imputation to replace missing responses. Unique code values were
assigned to the recency-of-use variable when such logical imputation
occurred. These code values are readily identifiable by the phrase
"... LOGICALLY IMPUTED" or "... LOGICALLY ASSIGNED" in the code
Data were weighted based on the three stages
of sampling that were used. The person-level sampling weight is the
product of the three-stage sampling weights, each of which is equal to
the inverse of the selection probability for that stage. 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
To protect the anonymity of respondents, all
variables that could be used to identify individuals have been deleted
from the public use file.
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.

Extent of Processing: 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.
Restrictions: Users are reminded by the United States Department of Health and Human Services that these data are to be used solely for statistical analysis and reporting of aggregated information and not for the investigation of specific individuals or treatment facilities.
