ABSTRACT
OBJECTIVE: San Francisco's comprehensive restriction on flavoured tobacco sales applies to all flavours (including menthol), all products and all retailers (without exemptions). This study evaluates associations of policy implementation with changes in tobacco sales in San Francisco and in two California cities without any sales restriction. METHODS: Using weekly retail sales data (July 2015 through December 2019), we computed sales volume in equivalent units within product categories and the proportion of flavoured tobacco. An interrupted time series analysis estimated within-city changes associated with the policy's effective and enforcement dates, separately by product category for San Francisco and comparison cities, San Jose and San Diego. RESULTS: Predicted average weekly flavoured tobacco sales decreased by 96% from before the policy to after enforcement (p<0.05), and to very low levels across all products, including cigars with concept-flavour names (eg, Jazz). Average weekly flavoured tobacco sales did not change in San Jose and decreased by 10% in San Diego (p<0.05). Total tobacco sales decreased by 25% in San Francisco, 8% in San Jose and 17% in San Diego (each, p<0.05). CONCLUSIONS: San Francisco's comprehensive restriction virtually eliminated flavoured tobacco sales and decreased total tobacco sales in mainstream retailers. Unlike other US flavoured tobacco policy evaluations, there was no evidence of substitution to concept-flavour named products. Results may be attributed to San Francisco Department of Health's self-education and rigorous retailer education, as well as the law's rebuttable presumption of a product as flavoured based on manufacturer communication.
ABSTRACT
Introduction: Research is needed to understand the frequency of e-cigarette impressions in scripted television and movies, especially in scripted content with characters and storylines that may appeal to young adults. This study aimed to determine the extent of e-cigarette-related imagery and dialogue in Netflix content popular with young adults. We also determine the demographics and character qualities of actors shown holding e-cigarettes. Methods: Nielsen ratings data were used to compile a list of the most popular Netflix original films and TV shows among U.S. viewers 18-24 years old between June 1, 2020, and May 31, 2021. We used a sample of 12 films and 113 TV episodes from 12 series. Three coders were trained to analyze a total of 101 h of content for the presence of e-cigarettes, level of use, type of characters holding e-cigarettes, brand visibility, and the presence of vaping-related dialogue. Twenty percent of all episodes/films were double coded to ensure reliability. Results: Out of 125 titles, 16 (13%) had e-cigarette-related content. Thirteen titles (10%) showed at least one character holding an e-cigarette, and three others mentioned vaping without showing e-cigarettes. The total time of e-cigarettes onscreen amounted to 399 s and the average screen time for e-cigarettes was 31 s. Ninety-nine percent of the time an e-cigarette appeared on screen it was being held by a character. Conclusion: This study documented recent e-cigarette imagery found on Netflix and demonstrates the need for health communication campaigns to denormalize e-cigarette use, particularly among susceptible populations, such as young adults.
