Cigarette Trafficking and Tax Parity: Results of a Natural Tax Experiment
Objectives: In this study, we examine the impact of a natural quasi-experiment in tax parity on domestic cigarette trafficking in 3 US cities. Methods: We examined 3 northeastern US cities that experienced tax changes between 2011 and 2015 ($2.51 to $3.51 in Boston; $3.46 to $3.75 in Providence; and $1.60 to $3.60 in Philadelphia). Littered packs were collected from a random sample of census tracts in each city. The share of packs bearing proper local, known non-local, foreign or unknown, or no tax stamp was calculated for each city to determine domestic cigarette trafficking rates in 2011 and 2015. Results: The rate of trafficked packs decreased in Boston from a range of 3*6.0% to 37.1% in 2011 to a range of 8.0% to 11.3% in 2015. In Providence, trafficking decreased from a range of 30.2% to 57.0% of packs in 2011 to 7.8% to 12.1% of packs in 2015. In Philadelphia, trafficking increased from a range of 1.9% to 2.2% in 2011 to a range of 18.9% to 41.4%. These changes were statistically significant. Conclusions: Policies to encourage greater tax parity may decrease domestic cigarette trafficking, whereas policies that increase tax disparities may increase consumption of cigarettes from non-local sources.
