Transitions in current tobacco product use among young adults (aged 18-24 years) and older adults (aged 25+ years) in the United States: 2013–2014 to 2014–2015. Notes. Each bar in the figure represents a mutually exclusive tobacco product user group at Wave 1 (W1). N underneath each bar indicates the weighted population size for each tobacco product user group at W1 (i.e., the scale of the y-axis differs across bars). For each tobacco product user group at W1, transitions between W1 and Wave 2 (W2) are indicated by the colored distribution of each bar; for example, among the 18,887,580 young adult No tobacco users at W1, 89% continued No tobacco use at W2 and 6% transitioned to Combustible only use at W2. Current tobacco use defined as: for cigarettes, currently using everyday/somedays and smoked at least 100 cigarettes in lifetime; for hookah, currently using everyday/somedays/usually weekly/usually monthly; for all other products, currently using everyday/somedays. ‘Combustible’ includes cigarettes, traditional cigars, cigarillos, filtered cigars, hookah, pipe tobacco; ‘noncombustible’ includes smokeless tobacco, snus pouches, dissolvable tobacco; ‘ENDS’ includes e-cigarettes at each wave and e-products at W2. ‘No tobacco’ defined as no current use of any tobacco product. Estimates are suppressed when unweighted denominator <50 or RSE>30%; all estimates for ‘Noncombustible + ENDS’ are suppressed. Non-suppressed estimates <3 are not shown in the figure (for readability) but are shown in the appendix.
