Note well: "tobacco use" is a umbrella term that includes e-cigarette use (with nicotine), since the nicotine in vape juice is derived from tobacco plants. Also note: "combustible tobacco product use" declined.<p>"Among high school students, during 2011–2018, no significant trend in the reported use of any tobacco product overall was observed (Figure 2). However, changes were observed for individual tobacco products over this period. A significant nonlinear increase in current e-cigarette use occurred from 2011 (1.5%) to 2018 (20.8%). During 2011–2018, significant linear declines in combustible tobacco product use (from 21.8% to 13.9%) and ≥2 tobacco product use (from 12.0% to 11.3%) occurred; by product type, significant linear declines occurred for cigars (from 11.6% to 7.6%), smokeless tobacco (from 7.9% to 5.9%), and pipe tobacco (from 4.0% to 1.1%). A significant nonlinear decline was observed for cigarettes (from 15.8% to 8.1%). A significant nonlinear change during 2011–2018 was observed for hookahs (from 4.1% to 4.1%).<p>Among middle school students, no significant change in use of any tobacco product overall occurred during 2011–2018 (Figure 3).
