1 In 1965 and 1966, the question was asked but the variable was not included on the data file. Information from a follow-up question (number of cigarettes currently smoked) serves to identify current smokers in these years. In 1992, questions about current smoking status were asked in two ways in a split sample experiment. The original “Do you smoke now?” question was asked in the Cancer Control questionnaire and followed by a question asking about smoking every day or some days. The “Do you smoke every day, some days, or not at all?” question was asked in the Cancer Epidemiology questionnaire and became the standard smoking question from 1993 forward.
2 Asked only of adults who said they smoked “some days.”
3 For someday smokers the question asked about number of cigarettes on days smoked.
4a Information about type {size/filter or non-filter/plain or menthol/hard or soft pack} varies by year. See questionnaires for details.
4b “At the request of NHIS data users, the brand names and types of cigarettes associated with previously released NHIS tobacco smoking files, are being released to the public as separate listings.” Tobacco Brand
5 In 1992, the question was limited to ever smoked every day for at least 6 months.
6 In 1983, the question asked about quit methods ever used in the past 5 years only.
7 The minimum number of pipefuls of tobacco and minimum number of cigars vary by year. See questionnaires for details.
8 In some years, question was phrased in terms of the past 30 days. See questionnaires for details.
9 Asked of both current and former tobacco users.
10Beginning in 1992, questions related to medical surveillance were expanded from cigarette smoking only to include cigarette smoking and other tobacco use.
