Note. F1, first fall after high school; S1, first spring after high school; F2, second fall after high school; S2, second spring after high school; non, nonsmokers; LI, light and intermittent smokers; and heavy, heavy smokers. This analysis included all participants who had no missing data on the five assessments of binge drinking (n = 705); dashes indicate the reference stage. NA = odds ratios are not presented for transitions for which fewer than 5% of stage members made the transition.
