Unadjusted weighted percent of tobacco use^a among four age groups of Population Assessment of Tobacco and Health Study Wave 4 adolescents (age 12-17) and young adults (age 18-24).^b

notes:

^a Never use = never used tobacco; Noncurrent use = ever used tobacco, but not in the past 30 days; Current noncombustible use only = exclusive noncombustible (e-cigarette^c, smokeless tobacco, or snus) use in the past 30 days; Current combustible use = combustible (cigarette, pipe, hookah, or cigar) use in the past 30 days regardless of noncombustible use. Error bars represent 95% confidence interval.

^b N = 21,054 adolescents and young adult respondents: 12-14 N = 6,315; 15-17 N = 6,246; 18-20 N = 4,574; 21-24 N = 3,919.

^c At W4, participants were asked about use of any e-products (e-cigarettes, e-cigars, e-pipes, and e-hookah), all of which are referred to as e-cigarettes here.
