Simulating the Impact of a Cigarette Minimum Floor Price Law on Adult Smoking Prevalence in California

Minimum floor price laws are an emerging tobacco control policy that sets a minimum price below which a specific tobacco product cannot be sold. This policy targets cheaper products and may disproportionately impact consumers choosing low-price brands or using discounts to reduce prices. By using a microsimulation model to predict changes in smoking for different population groups in California under several floor price scenarios, this study demonstrated that minimum floor price laws have the potential to reduce adult smoking prevalence overall, and especially for lower-income tobacco users.
