Figure 5. Use of Any Tobacco Products Within 5 Minutes of Waking.

A, The estimated number of adolescents with high levels of nicotine dependence and who were sole users of e-cigarettes diverged from the numbers for other products in 2018, exceeding the sum of use of cigarettes and all other products combined. B, Considering dual-product users with the other products confirms that e-cigarette users began to exceed use of all other tobacco products among adolescents with high levels of nicotine dependence. The 2021 numbers may underestimate tobacco use compared with earlier years, as discussed in the Limitations subsection of the Discussion section. SLT indicates smokeless tobacco.
