This study examines how state cigarette excise taxes impact the percentage of income smokers spend on cigarettes, particularly for lower-income smokers. The study analyzes data from the 2009-10 and 2012-13 National Adult Tobacco Surveys. A linear regression model finds that a $1 increase in state cigarette excise tax is associated with a 1-2% increase in the percentage of income smokers spend on cigarettes. This, along with coefficients for other income variables, indicates state cigarette taxes have a regressive effect, impacting lower-income smokers more.
