Tobacco use

Updated September 16, 2026

Tobacco products include multiple varieties of products, including cigarettes, cigarette tobacco, roll-your-own tobacco, smokeless tobacco, electronic cigarettes, cigars, hookahs, pipe tobacco, nicotine gels, and dissolvables. Vapes, vaporizers, vape pens, hookah pens, e-cigarettes or e-cigs, and e-pipes are some of the many terms used to describe electronic nicotine delivery systems, which are battery-powered tobacco products that typically deliver nicotine in the form of an aerosol. Cigars include premium cigars, little filtered cigars, and cigarillos. Use of tobacco products is measured differently by the data systems used in Health, United States.

Monitoring the Future (MTF)

This school-based survey of secondary school students collects information on tobacco use by using self-completed questionnaires. Information on current cigarette smoking is obtained for 12th graders (starting in 1975) and for 8th and 10th graders (starting in 1991), based on the following question: “How frequently have you smoked cigarettes during the past 30 days?” Information on current vaping is obtained for 8th, 10th, and 12th graders (starting in 2015), based on the following question: “During the last 30 days, on how many days (if any), have you used electronic cigarettes (e-cigarettes)?” In 2017, questions on vaping were revised to include separate questions about vaping nicotine, marijuana, and just flavoring. Students are first asked the screener question: “To ‘vape’ is to use a device such as a JUUL, vape-pen, e-cigarette, e-hookah, or e-vaporizer to inhale a vapor into the lungs. Have you ever vaped?” Students who reply yes are then asked additional questions about specific substances they have vaped over different time frames. They are asked about nicotine with the question: “On how many occasions (if any) have you vaped nicotine in the last 30 days?” They are also asked about vaping marijuana and vaping just flavoring in the same format.

National Health Interview Survey (NHIS) (last updated August 2024)

Information about cigarette smoking is obtained for adults age 18 and older. Current cigarette smokers are defined as ever smoking 100 cigarettes in their lifetime and currently smoking every day or some days.

In 1991, a transition to a new measure of smoking status was initiated. For the first time, NHIS distinguished smokers who smoked daily from those who smoked less often than daily. Respondents were first asked, “Have you smoked at least 100 cigarettes in your entire life?” If yes, “Do you smoke cigarettes now?” To those who said yes to the question about current cigarette smoking, the question was asked, “Do you smoke cigarettes every day or some days?” For those who said no to the current smoking status question, the question was asked, “Do you smoke cigarettes ‘not at all’ or ‘some days’?” This additional follow-up resulted in the classification of people as “someday smokers” who would otherwise have been considered former smokers, because they initially said that they did not smoke now.

Starting in 1997, smoking questions are asked of all Sample Adults. Smoking data were not collected in 1996. In 1993–1995, estimates of cigarette smoking prevalence were based on a one-half sample of all respondents. Data from the cigarette smoking questions used in Health, United States are available in the following files: Sample Adult (1997–2022), year 2000 objectives (year2000; 1993–1995), Cancer Control (canccntl; 1992), Cancer Epidemiology (cancepid; 1992), Health Promotion and Disease Prevention (hpdpsamp; 1985, 1990, 1991), Alcohol and Health Practices (alcoholh; 1983), Smoking (smokingx; 1979), Hypertension (hyperten; 1974), and Core (person; 1965).

In 2014, questions were added to NHIS on the use of e-cigarettes; however, estimates of e-cigarette use from NHIS are not presented in Health, United States. For more information on survey methodology and sample sizes for NHIS cigarette smoking data, see the NHIS Adult Tobacco Use Information website.

National Survey on Drug Use and Health (NSDUH) (last updated June 2023)

Interviewers conduct in-person, computer-assisted interviews of a sample of children age 12 and older at their home. Information on current cigarette smoking is obtained based on the following question: “Now think about the past 30 days, that is, from [DATE] up to and including today. During the past 30 days, have you smoked part or all of a cigarette?”

To measure current use of any tobacco product, respondents are asked about the use of each specific tobacco product on 1 or more days in the past 30 days, including cigarettes, smokeless tobacco (such as snuff, dip, chewing tobacco, or snus), cigars, and pipe tobacco. Any amount of use reported in the past 30 days is classified as recent use of that tobacco product. Cigarette smoking and use of any tobacco product do not include electronic cigarettes or other vaping devices.
