Figure 1. (a) Cigarette and (b) e-cigarette purchase locations of past 30-day cigarette and e-cigarette users, respectively, Pre-T21 (Ncig = 146; Ne-cig = 193) and Post-T21 (Ncig = 159; Ne-cig = 134), among past 30-day users.

*P<0.05 for multivariate logistic regression models of the association of time (Pre-T21 vs. Post-T21) with reported purchase location (primary outcome measure for each purchase location, in separate models); This question was asked with select-all-that-apply response options (categories are not mutually exclusive); Tests of statistical significance were coadjusted for gender, race/ethnicity, ALA grade, and included a random intercept of ID.
