AOR = adjusted odds ratio; CI = confidence interval; HS = high school; %Poly = prevalence of polytobacco use. Ellipsis indicates not included in the model. Statistically significant AOR results are noted in bold. The sample sizes by subgroups of current cigarette smokers, current cigar users, current chewing tobacco users, and current snuff users are the same as those shown in the sample size columns of Table 2 .
