Subgroup analyses by age group and income group, stratified by smoking status (results not shown), indicated that increases in cigarette taxes were significantly associated with reductions in typical quantity of alcohol consumption among smokers aged 50 and older (b = −0.23, p = 0.04) and smokers in the lowest annual income group ($0 – $19,999; b = −.24, p = 0.04). Further, increases in cigarette taxes were significantly associated with reductions in frequency of binge drinking among young adult smokers aged 18–29 (b = −0.19, p = 0.02). Cigarette tax increases were not associated with changes in typical quantity of alcohol consumption nor frequency of binge drinking in non-smokers regardless of demographic subgroup, nor with changes in frequency of alcohol consumption regardless of smoking status or demographic subgroup.
