Increasing taxes on cigarettes and strengthening smoke-free air (SFA) policies are two of the most effective population-based methods to prevent smoking initiation and induce smokers to quit or reduce their cigarette consumption (Bader et al., 2011; Hahn, 2010; Hopkins et al., 2010; Liang et al., 2003; Peterson et al., 1992; Task Force on Community Preventive Services, 2005). Because co-use of tobacco and alcohol is so common, strengthening tobacco policies might not only decrease cigarette smoking but also reduce alcohol use. Studies on the cross-price effects of alcohol and tobacco in Sweden, Australia, Taiwan, and Italy found that increasing cigarette prices, through excise taxes or other means, leads to decreases in alcohol demand (Aristei & Pieroni, 2010; Bask & Melkersson, 2004; Cameron & Williams, 2001; Lee, 2007; Lee et al., 2010; Pierani & Tiezzi, 2008). Studies in the U.S., however, have yielded mixed results. Three studies found an increase in cigarette price/tax associated with an increase in alcohol use; though one of these focused only on spirits and another focused on adults age 51 years and above (Decker & Schwartz, 2000;
