PR, prevalence ratio.

a

Poisson regression models adjusted for age, sex assigned at birth, race and ethnicity, identification as sexual or gender minority, and other substance use. Results are reported as prevalence ratios; robust SEs were used to compute 95% CIs.

b

Electronic vapor products included e-cigarettes, electronic cigars, electronic pipes, vape pipes, vaping pens, electronic hookahs, and hookah pens (examples: blu, NJOY, Vuse, MarkTen, Logic, Vapin Plus, eGo, and Halo).

c

Individuals responding “I did not use any tobacco products in the last 12 months” were not included in this item’s analysis.
