Note: All models include adjustments for age, gender, race/ethnicity; text in red indicates a significant value (p < 0.05). Susceptibility = Youth who reported other than the strongest negative response to each of the three questions regard-ing tobacco product use. Poly-tobacco User: Cigarette + Other Products(s) = Youth who reported use of cigarettes AND other tobacco products. Other Non-Combustible User = Youth who reported use of smokeless, snus, or multiple non-combustible product use. Non-Cigarette Combustible Product User = Youth who reported use of cigars, pipe, and/or hookah only or multiple non-cigarette combustible product use.
