The effect of cigarette and e-cigarette taxes on prescriptions for smoking cessation medications.

ABSTRACT:

Objective

To test the effect of cigarette and e-cigarette taxes on prescriptions for smoking cessation medications.

Data source

Symphony Health, IDV all-payer prescription claims data for the United States over the period 2009-2017. Prescription fills for smoking cessation products were provided at the patient's age, patient's sex, brand/generic, payment type, year, and quarter levels.

Study design

We study the effect of state-level cigarette and e-cigarette tax rates on prescriptions for smoking cessation medications using two-way fixed effect modified difference-in-differences regressions. We also use a multiperiod difference-in-differences estimator robust to bias from dynamic and heterogeneous treatment effects with a staggered policy rollout.
