In addition to sex differences in the association between changes in cigarette taxes and drinking outcomes, increases in statewide cigarette taxes were associated with reductions in quantity of alcohol consumption among adult smokers aged 50 and older and smokers in the lowest annual income group ($0 – $19,999). Further, increases in statewide cigarette taxes were associated with greater reductions in frequency of binge drinking among young adult smokers, such that when cigarette taxes increased, young adult smokers binged approximately 10 fewer times per year (a 24% reduction). These findings are consistent with existing knowledge that young adults and individuals with low SES are especially responsive to cigarette taxes (Chaloupka et al., 2012), and is consistent with the recent findings that smoke-free policies in drinking venues afford protection against the onset of alcohol use disorders among young adult drinkers (Young-Wolff et al., 2013). Given evidence that alcohol-tobacco comorbidity is greatest among young adults and decreases with increasing age (Falk et al., 2006), these results have potential implications for prevention among vulnerable groups.
