Objectives. To examine the impact of local laws prohibiting tobacco sales in pharmacies in California and Massachusetts, the only 2 US states in which such municipal laws exist.
Methods. We analyzed longitudinally the tobacco retailer density at the city level from tobacco retailer license data in California (2005–2013) and Massachusetts (2004–2014).
Results. After adjustments, the reduction in tobacco retailer density over time was 1.44 (95% confidence interval [CI] = 1.37, 1.51) to 3.18 (95% CI = 1.11, 5.25) times greater in cities with a tobacco-free pharmacy law than in cities without such a law.
Conclusions. Tobacco-free pharmacy laws are associated with a greater reduction in tobacco retailer density over time in California and Massachusetts.
