Note: Odds ratios are reported. 95% CI clustered at the state level are in parentheses. Other controls in Table 2 such as year and state fixed effects, gender, race, education, duration dependence, SFA laws in restaurants, PUP index, state spending on tobacco control programs and SFA index are not shown. ^* p ≤ 0.1, ^** p ≤ 0.05, ^*** p ≤ 0.01.
