FIGURE 2.

This figure is a line graph showing use of any tobacco product; cigarettes, cigars, cigarillos, or little cigars; electronic vapor products; smokeless tobacco; and two or more tobacco products each year from 1991 through 2019 according to data from the Youth Risk Behavior Survey. During 2015–2019, a significant linear increase occurred in prevalence of current electronic vapor products use (from 24.1% to 32.7%). During 1991–2019, a significant linear decrease in current cigarette smoking occurred, (from 27.5% to 6.0%). A significant quadratic trend in cigarette smoking also was identified: a 6-year increase in prevalence (from 27.5% in 1991 to 36.4% in 1997) was followed by a 22-year decrease (from 36.4% in 1997 to 6.0% in 2019). Additionally, during 1997–2019, a significant linear decrease (from 22.0% to 5.7%) occurred in the overall prevalence of current cigar smoking. A significant quadratic trend also was identified: a 16-year decrease in prevalence (from 22.0% in 1997 to 12.6% in 2013) was followed by another 6-year decrease, but at a different rate of decrease (from 12.6% in 2013 to 5.7% in 2019).

Prevalence of current tobacco product use, by year — Youth Risk Behavior Survey, United States, 1991–2019*

* Logistic regression analyses were used to model linear and quadratic time effects while controlling for sex, grade, and race/ethnicity. Electronic vapor products: significant linear increase (2015–2019); cigarettes: significant linear decrease (1991–2019); significant quadratic trend: increase during 1991–1997, decrease during 1997–2019; cigars/cigarillos/little cigars: significant linear decrease (1997–2019); significant quadratic trend: decrease 1997–2013; decrease 2013–2019 (different rate of decrease). Differences from 2017 to 2019 were assessed by t-test (p<0.05): A significant increase occurred in use of electronic vapor products and any tobacco product; a significant decrease occurred in use of cigarettes, cigars/cigarillos/little cigars and smokeless tobacco; and no change occurred in use of ≥2 products.
