Background In June 2018, San Francisco voters upheld the first comprehensive prohibition on sales of flavoured tobacco products (all products including menthol, everywhere in the city with no exceptions).

Methods This paper used data collected by the San Francisco Department of Public Health as part of its implementation and enforcement of San Francisco’s city-wide ban on the sale of flavoured tobacco products. Every licensed tobacco retailer was visited and inspected. The San Francisco Department of Public Health and volunteers conducted an educational campaign from September 2018 to December 2018, including emailing all licensed tobacco retailers about the law, mailing a fact sheet poster, conducting four listening sessions and visiting permitted tobacco retailers to educate them about the law and solicit questions.

Results Compliance inspections started in December 2018, which found that compliance was 17%. Compliance increased in January 2019 and averaged 80% between January 2019 and December 2019. After the phase-in period, all retailers were visited as part of routine inspections. This effort resulted in 80% compliance.

Conclusion Including retailer education prior to enforcement can result in compliance with a comprehensive ban on the sale of menthol and other flavoured tobacco products.
