This guide provides links to NHIS tobacco information, including questionnaires, documentation, data file information, SAS/SPSS/Stata input statements and data sets for each data year in which NHIS tobacco use questions were asked.
NHIS data collection technology has changed over the years with resulting changes in terminology and the display of survey information. Terminology used on the NHIS website for the three major NHIS data collection periods – 2004 to present, 1997-2003, and 1965-1995 – is summarized here.

Notice to data users using 64-bit computers running Microsoft operating systems:
NHIS Public Use data sets from 1970-2005 with the .exe file type are unable to be extracted on 64-bit computers running Microsoft operating systems. Data users are advised to rename the .exe files as .zip files and the data sets will extract correctly. This workaround is suggested for data years 1970-2005. Beginning with 2010 data year, ASCII files are being released as .zip files.
2004 to Present:
Beginning in 2004 and continuing to the present, all NHIS survey information can be accessed from the page titled Questionnaires, Datasets, and Related Documentation, 1997 to (current data year). Links to questionnaires and other survey-related documents are found by scrolling down to the year of interest. For data and documentation (other than the questionnaires and the survey description), click on “Data Release” for the year of interest and click on appropriate links indicated below.

1965-1995
For 1965-1995, survey information is organized by data year in descending order. Links to most documents for these years are provided below. For data years 1974, 1976, and 1978-1980, variables that originally came from the public use person file, although included on the data files, are not described separately in the documentation. Rather, users are referred to the “Person Public Use Record Layout.” For convenience, links to the appropriate pages in Person Public Use documentation are provided within the smoking file documentation. The person file documentation is part of a large document that describes all NHIS core data files for the year (person, condition, doctor visit, hospital, etc). These files are large and may take some time to download. All NHIS survey information for period 1965-1995 can also be accessed from the page titled Internet-Available Datasets and Related Documentation 1996-Prior. The questionnaires are located in appendix III of Current Estimates reports for each of these years. These reports are large and may take some time to download.
