The San Francisco Ban and the Future of e-Cigarettes

The impact of two state-level approaches to restricting the sale of flavored tobacco products

Background

Flavored tobacco products are highly appealing to youth. The Federal government lacks a comprehensive flavored tobacco products policy and states have adopted different approaches restricting these products. This study analyzes the impact of Massachusetts’ comprehensive prohibition and New Jersey’s partial restriction on the sale of flavored tobacco products.

Methods

NielsenIQ Retail Scanner data were used to construct four log per capita dependent variables: e-liquid milliliters, cigarette packs, cigars, and smokeless tobacco ounces for products flavored as fruit, menthol, mint, tobacco and other. All models used difference-in-differences regressions, with Virginia and Pennsylvania serving as controls. The models controlled for state level product prices, population percentages by race/ethnicity, proportion male, median household income, unemployment rate, minimum legal sales age, tobacco 21 policies, and cumulative cases and deaths of COVID-19; the models accounted for time-specific factors by using 4-week period fixed-effects.

Results

There was a significant decrease in sales across all flavored tobacco products in Massachusetts, including fruit [-99.83%, p < 0.01], menthol [-98.33%, p < 0.01], and all other flavored [-99.28%, p < 0.01] e-cigarettes. The cigar group “all other-flavors" [-99.92%, p < 0.01] and menthol flavored cigarettes [-95.36%, p < 0.01] also significantly decreased. In New Jersey, there was a significant decrease in per capita sales of menthol-flavored e-cigarettes [-83.80%, p < 0.05] and cigar group “all other-flavors" experienced a significant increase in per capita sales [380.66%, p < 0.01].

Conclusions

This study contributes to the growing body of evidence demonstrating the impact of sales prohibitions on reducing sales of flavored tobacco products. Statewide comprehensive approaches appear more effective than partial restrictions and should be prioritized.

Implications

Results from this study support emerging research that demonstrates the promising effects of comprehensive flavoring sales prohibitions. This study can be used to inform future flavored tobacco product policy solutions developed by advocates and policy makers to curb overall tobacco initiation and use by youth and adults.

The Illegal Experimental Tobacco Marketplace I: Effects of Vaping Product Bans

OBJECTIVES

Banning vaping products may have unintended outcomes, such as increased demand for illegal products. This study experimentally examined the effects of a vaping ban and a flavored vaping ban on the probability of purchasing illicit vaping products, and factors affecting purchasing from a hypothetical illegal marketplace.

METHODS

A crowdsourced sample of exclusive cigarette smokers, exclusive e-cigarette users, and frequent dual users (n = 150) completed hypothetical purchasing trials in an Experimental Tobacco Marketplace under three conditions (no ban, vaping ban, and flavored vaping ban). Participants chose to purchase in a hypothetical legal experimental tobacco marketplace (LETM) or illegal experimental tobacco marketplace (IETM). Vaping products were available in each marketplace depending on the condition. Other tobacco products were always available in the LETM. A hypothetical illicit purchase task with five fine amounts assessed the effect of monetary penalties.

RESULTS

Participants from all groups were more likely to purchase from the IETM when product availability in the LETM was more restricted, with e-cigarette users being most affected. The likelihood of purchasing illegal products was systematically decreased as monetary penalties associated with the IETM increased, with e-cigarette users showing greater persistence in defending their illicit purchases.

CONCLUSIONS

Restricting vaping products from the marketplace may shift preference towards purchasing vaping products in the illegal marketplace. Nevertheless, penalties imposed on consumer's behavior might be effective in preventing illicit trade. The IETM is a methodological extension that supports the utility and flexibility of the ETM as a framework for understanding the impact of different tobacco regulatory policies.

IMPLICATIONS

This study suggests that limiting or banning vaping products as a possible strategy to reduce the adverse effects of vaping products could result in some tobacco-users seeking banned products from illegal sources. Monetary fines were shown to reduce illegal purchases. Therefore, policymakers should consider implementing strategies that may mitigate illegal purchases.

Trendy e-cigarettes enter Europe: chemical characterization of JUUL pods and its aerosols

The popularity and the high nicotine content of the American pod e-cigarette JUUL have raised many concerns. To comply with European law, the nicotine concentration in the liquids of the European version, which has been recently released on the market, is limited to below 20 mg/mL. This limit can possibly be circumvented by technological adjustments that increase vaporization and consequently, elevate nicotine delivery. In this study, we compare vapor generation and nicotine delivery of the initial European version, a modified European version, and the original American high-nicotine variant using a machine vaping set-up. Additionally, benzoic acid and carbonyl compounds are quantified in the aerosol. Further, concentrations of nicotine, benzoic acid, propylene glycol, and glycerol, along with the density and pH value of JUUL e-liquids have been assessed. Whereas the initial European version did not compensate for the low nicotine content in the liquid, we provide evidence for an increased vaporization by the modified European version. As a consequence, nicotine delivery per puff approximates the American original. Notably, this is not associated with an increased generation of carbonyl compounds. Our data suggest a similar addictiveness of the enhanced European version and the original American product.

Electronic cigarettes: where to from here?

Although the usage of electronic (e)-cigarettes (EC) and similar devices has gained in popularity as an apparent smoking cessation strategy, serious concerns are emerging in relation to both the efficacy of this strategy, as well as the inappropriate use of these devices. While the comparative safety of e-cigarettes is based on the reasonable contention that the levels of inhaled toxicants present in the aerosols generated by these devices are considerably lower than those present in tobacco smoke, the perception that they are indeed relatively risk-free is being challenged on several fronts. Notwithstanding lack of convincing evidence of efficacy as a superior smoking cessation strategy, foremost among emerging concerns is the increasing use of electronic nicotine-delivery devices by young never-smokers. Other concerns include increasing levels of sophistication in the design and capacity of these devices in relation to nicotine content and delivery, the potential threat of manipulation of the contents of e-liquids, as well as other additives such as illicit drugs and other potentially toxic agents that can be vaporised. These issues, together with the potential risks to respiratory health, specifically "e-cigarette or vaping product use-associated lung injury" represent the major thrusts of this review.
