FIGURE 2.

Estimated percentage of high school students who currently use any tobacco product,* any combustible tobacco product,^† ≥2 tobacco product types,^§ and selected tobacco products — National Youth Tobacco Survey, 2011–2018^¶,**^,††

Abbreviation: e-cigarettes = electronic cigarettes.

* Any tobacco product use was defined as use of e-cigarettes, cigarettes, cigars, hookahs, smokeless tobacco, pipe tobacco and/or bidis (small brown cigarettes wrapped in a leaf) on ≥1 day in the past 30 days.

^† Any combustible tobacco product use was defined as use of cigarettes, cigars, hookahs, pipe tobacco, and/or bidis on ≥1 day in the past 30 days.

^§ Use of ≥2 tobacco product types was defined as use of ≥2 of the following tobacco products: e-cigarettes, cigarettes, cigars, hookahs, smokeless tobacco, pipe tobacco, and/or bidis on ≥1 day in the past 30 days.

^¶ During 2017–2018, current use of any tobacco product, ≥2 types of tobacco products, and e-cigarettes significantly increased (p<0.05).

** During 2011–2018, current use of combustible tobacco products, ≥2 types of tobacco products, cigars, smokeless tobacco, and pipe tobacco exhibited linear decreases (p<0.05). Current use of cigarettes exhibited a nonlinear decrease (p<0.05). Current use of hookahs exhibited a nonlinear change (p<0.05). Current use of e-cigarettes exhibited a nonlinear increase (p<0.05). No significant trend in use of any tobacco product overall was observed.

^†† Beginning in 2015, the definition of smokeless tobacco included chewing tobacco/snuff/dip, snus, and dissolvable tobacco to better reflect this class of tobacco products. Thus, estimates for individual smokeless tobacco products (chewing tobacco/snuff/dip, snus, and dissolvable tobacco) are not reported. This definition was applied across all years (2011–2018) for comparability purposes.
