Effect of tobacco sales bans on retail sales in Beverly Hills and Manhattan Beach, California, USA: a synthetic difference-in-differences analysis.
Article in Tobacco control, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundOn 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.
methodsWe 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.
resultsTobacco sales in included stores ceased within 3 months of the policy going into effect in Beverly Hills and nearly ceased by December 2021 in Manhattan Beach. A shift in cross-border shopping was detected for cigars only. Non-tobacco product sales did not significantly change in either city or the border area.
conclusionThe tobacco sales bans in Beverly Hills and Manhattan Beach nearly eliminated local tobacco sales in the included stores, without prompting substantial cross-border shopping. Stability of non-tobacco product sales for included stores suggests these policies did not adversely affect local retail economies. These results suggest the viability of tobacco sales bans as an effective tobacco control strategy.
