Note. Gender (1 = Female, 0 = Male); Race (1 = White, 0 = other); Parental education (0 = both parents have greater than high school education, 1 = at least one parent has a high school education or less; 2 = both parents have a high school education or less); Smoking (0 = never smoked, not even a puff of a cigarette, 1 = smoked a puff but never a whole cigarette, 2 = smoked a whole cigarette but not in the past 30 days, 3 = smoked in the past 30 days, 4 = smokes weekly; 5 = smokes daily); Alternative tobacco use (1 = used alternative tobacco products in the past 30 days, 0 = did not use alternative tobacco products in the past 30 days). OR = odds ratio; ci = confidence interval; bolded odds ratios are significant at p < .001. All odds ratios are adjusted odds ratios (adjusted for sex, race, parental education, and tobacco use).
