In this report, we discuss issues for the Legislature to consider as it decides whether to change the state’s approach to taxing e‑cigarettes. We find that a tax based on nicotine content has some advantages. We also suggest that the Legislature consider a wide range of possible tax rates. Once the Legislature has chosen a rate, we recommend indexing the rate to inflation and revisiting it frequently to assess whether further adjustments are warranted. If the Legislature chooses to enact a new tax on e‑cigarettes, we recommend that it take an approach to revenue allocation that prioritizes flexibility.
