Beer taxes associate with lower alcohol and cigarette use; cigarette taxes associate with lower cigarette but higher...

Background: There is a yet unmet opportunity to utilize data on taxes and individual behaviors to yield insight for analyzing studies involving alcohol and cigarette use.Objectives: To inform the direction and strength of their mutual associations by leveraging the fact that taxation can affect individual consumption, but individual consumption cannot affect taxation.Methods: We linked state-level data on cigarette and beer taxes in 2009-2020 with individual-level data on self-reported current cigarette and alcohol use from the Behavioral Risk Factor Surveillance System, a telephone survey by the Centers for Disease Control and Prevention that is representative of the population of each state in the United States. We constructed linear and logistic models to examine associations between a $1 increase in cigarette taxes per pack and a $1 increase in beer taxes per gallon and self-reported cigarette use and alcohol consumption (assessed as any current intake, average drinks/day, heavy drinking, and binge drinking), adjusting for survey year and individual characteristics.Results: Among 2,968,839,352 respondents (49% male), a $1 increase in beer taxes was associated with .003 (95% confidence interval [CI] -.013, .008) fewer drinks/day and lower odds of any drinking (odds ratio [OR] = .81 95%CI .80, .83), heavy drinking (OR = .96 95%CI .93, .99), binge drinking (OR = .82 95%CI .80, .83), and smoking (OR = .98 95%CI .96, 1.00). In contrast, a $1 increase in cigarette taxes was associated with lower odds of smoking (OR = .94 95%CI .94, .95) but .007 (95%CI .005, .010) more drinks/day, and higher odds of any drinking (OR = 1.10 95%CI 1.10, 1.11), heavy drinking (OR = 1.02 95%CI 1.01, 1.02), and binge drinking (OR = .82 95%CI .80, .83).Conclusion: Higher beer taxes were associated with lower odds of drinking and smoking, but higher cigarette taxes were associated with lower odds of smoking and higher alcohol consumption. These results suggest that alcohol intake may be a determinant of cigarette use rather than cigarette use as a determinant of alcohol intake.
