Effect of tobacco sales bans on retail sales in Beverly Hills and Manhattan Beach, California, USA: a synthetic difference-in-differences analysis.

ABSTRACT:

Background

On 1 January 2021, Beverly Hills and Manhattan Beach, California, became the first cities in the USA to ban tobacco product sales. We evaluated the effects of these policies on the sale of tobacco products and non-tobacco products by store in each city and its neighbouring area.

Methods

We used custom NielsenIQ retail scanner data by product and store to estimate actual and counterfactual sales trends for a set of convenience, grocery and drug stores in Beverly Hills and Manhattan Beach and their border areas using synthetic difference-in-differences models. Tobacco product unit sales were estimated overall and by tobacco product category. We also estimated changes in dollar sales of total non-tobacco products to evaluate broader economic impacts.
