Annual U.S. healthcare expenditures attributable to cigar smoking between 2001 and 2018, overall and by payer
Background: In 2022, 3.7% of U.S. adults currently smoked cigars. This study assesses cigar-smoking-attributable fractions in U.S. healthcare expenditures and associated annual healthcare expenditures overall and by payer, including publicly funded healthcare programs. Methods: Data were obtained from the 2000, 2005, 2010, and 2015–2017 National Health Interview Survey linked with corresponding panels from the Medical Expenditure Panel Survey data through 2018. The final sample (n = 53,733) was restricted to adults aged 25 + . Estimates from four-part models and data from the Personal Health Care component of the 2001–2018 National Health Expenditures Accounts were combined to estimate fractions of and annual healthcare expenditures attributable to cigar smoking. All models controlled for sociodemographic characteristics and health-related behaviors. Results: During 2001–2018, an estimated 1.8% (95% CI = 0.9%–3.4%) or $29.7 billion annually of U.S. healthcare expenditures could be attributed to cigar smoking. Most of this was funded by other third-party health insurance programs, a mix of private and public payers (e.g., Department of Veterans Affairs). Conclusions: Cigar smoking creates a preventable financial burden on the U.S. healthcare system. Health consequences associated with cigar smoking may remain after successful quitting. The findings underscore the importance of preventing initiation of cigar smoking and providing evidence-based cessation methods to reduce the health and economic burden of cigar smoking.

JUUL’s 2019 Removal of Mint-Flavored Pods and Changes to the Retail Environment of Electronic Nicotine Delivery Systems in Florida and the United States
Introduction: The increase in youth electronic nicotine delivery system (ENDS) use coincided with JUUL’s rapid rise, which prompted investigations and lawsuits aimed at this leading brand. In response, JUUL discontinued sweet flavors in late 2018, followed by mint flavors in November 2019. We assessed ENDS sales and prices at both the state and national level before and after JUUL’s removal of mint flavors. Aims and Methods: Nielsen retail sales data on ENDS products from convenience and food stores in 4-week aggregates were analyzed between January 2019 and January 2020 in Florida and the United States. Standardized units were created. Unit market share and growth rates were calculated for top brands and flavors in the periods before and after JUUL’s mint removal. Average prices within brand and product type were calculated. Results: Following JUUL’s removal of mint in November 2019, JUUL’s market share dropped from over 66% in Florida and the United States to 37.1% (Florida) and 55.1% (United States). In January 2020, the second leading brands were Puff Bar (15.0%) in Florida and Vuse (18.1%) in the United States. Mint market share decreased and share of all other flavor categories increased, particularly menthol and concept. Total ENDS sales increased in Florida but decreased in the United States. Average prices of ENDS devices decreased. Conclusions: While JUUL’s actions led to a decline in its sales, Puff Bar emerged and menthol and concept flavors experienced growth. Findings also demonstrate how changes by influential brands differentially affect purchase patterns at the national and state level. Implications: These findings support the growing body of evidence that tobacco industry self-regulation, with selective flavor removal by the leading ENDS brand in this case, is insufficient to reduce total ENDS sales, including sales of flavored products which are preferred by youth. Results suggest that brand and flavor substitution compensated for the removal of mint JUUL pods. Understanding changes to the ENDS market in response to industry actions, at both the state and national level, can inform future regulation and interventions. These findings can also inform efforts to prevent and reduce youth ENDS use.

Final Evaluation Findings forThis Free Life, a 3-Year, Multi-Market Tobacco Public Education Campaign for Gender and Sexual Minority Young Adults in the United States
This Free Life was the first multi-market, primarily digital campaign designed to change tobacco-related beliefs among lesbian, gay, bisexual, and transgender (LGBT) young adults. Our evaluation sought to determine whether campaign exposure resulted in changes in tobacco-related beliefs. We summarize awareness and receptivity at the conclusion of the campaign and assess the effect of campaign exposure on tobacco-related beliefs in campaign treatment markets compared with control markets. Twenty-four US designated market areas were selected to receive the campaign or serve as control markets. A baseline survey was conducted in 2016, with six follow-up surveys conducted approximately 6 months apart over the course of the 3-year campaign. 12 324 LGBT young adult survey participants were recruited via intercept interviews and social media. Campaign effects on outcomes were estimated using difference-in-difference panel regression models, with p-values corrected for multiple comparisons. Brand and ad awareness peaked in treatment markets approximately 2.5 years into the 3-year campaign and were significantly higher in treatment than control markets. Brand equity and ad receptivity were generally high and similar across LGBT subgroups. There were small but significant campaign effects on five tobacco-related beliefs, with difference-in-difference estimates ranging from 1.9 to 5.6 percentage points. This Free Life, the first multi-market tobacco public education campaign for LGBT young adults, reached and resonated with a large and diverse population, and had a small effect on beliefs involving social aspects of smoking. These findings should inform future communication efforts aimed at reducing tobacco use among LGBT young adults. Modest overall campaign effects suggest that further research on effective campaign messaging and delivery to LGBT young adults is needed. Campaign messaging style, delivery channels, and targeted outcomes likely contributed to these findings. Health communication efforts for LGBT young adults should consider the limitations of digital media in achieving sufficient exposure. Ad style and content optimized for a digital environment is an area that will benefit from further development.

Implementation of a comprehensive flavoured tobacco product sales restriction and retail tobacco sales
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 (pConclusions 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.

Sources of flavoured e-cigarettes among California youth and young adults: associations with local flavoured tobacco sales restrictions
Purpose This study compares access to flavoured JUUL and other e-cigarettes from retail, online and social sources among underage and young adult e-cigarette users who live in California jurisdictions that restrict sales of flavoured tobacco with the rest of the state. Methods An online survey used social media advertisements to recruit participants (n=3075, ages 15–29) who lived in one of nine jurisdictions that restrict sales (n=1539) or in the rest of state, and oversampled flavoured tobacco users. Focusing on past-month e-cigarette users (n=908), multilevel models tested whether access to flavoured JUUL and other e-cigarettes from retail, online and social sources differed by local law (yes/no) and age group (15–20 or older), controlling for other individual characteristics. Results The percent of underage users who obtained flavoured JUUL and other e-cigarettes in the past month was 33.6% and 31.2% from retail, 11.6% and 12.7% online, and 76.0% and 70.9% from social sources, respectively. Compared with underage and young adult users in the rest of California, those in localities that restrict the sales of flavoured tobacco were less likely to obtain flavoured JUUL from retail sources (Adjusted OR=0.54, 95% CI 0.36 to 0.80), but more likely to obtain it from social sources (Adjusted OR=1.55, 95% CI 1.02 to 2.35). The same pattern was observed for other brands of flavoured e-cigarettes. Conclusion Although local laws may reduce access to flavoured e-cigarettes from retail sources, more comprehensive state or federal restrictions are recommended to close the loopholes for online sources. Dedicated efforts to curtail access from social sources are needed.

Differential Relationship between Tobacco Control Policies and U.S. Adult Current Smoking by Poverty
The study’s purpose was to identify differences in the relationship between tobacco control policies and smoking by poverty. We matched state smoke-free air law coverage (SFALs), tobacco control funding (TCF), and cigarette taxes with individual current smoking and demographics from supplements to the Current Population Survey (1985–2015). We regressed (logistic) smoking on policy variables, poverty (p = 0.050). Among adults, SFALs, TCF, and tax were associated with less current smoking, and SFALs and TCF had differential relationships with smoking by poverty.
