FDA Considers Flavored Vapes to Help Adults Quit Smoking, Raising Youth Vaping Concerns

The Food and Drug Administration is considering a shift in its approach to flavored e-cigarettes, potentially allowing some flavors beyond tobacco and menthol to remain on the market. This move, outlined in draft guidance released this week, has sparked concern among public health experts who worry it could reverse progress in reducing youth vaping rates and introduce new health risks.

The FDA has, until now, largely focused on authorizing e-cigarettes only in tobacco and menthol flavors, aiming to avoid the sweet and fruity options that fueled a surge in teen vaping in the late 2010s. The new guidance suggests the agency might be more open to flavors like coffee, mint, or cinnamon, but only if manufacturers can demonstrate they appeal more to adult smokers looking to switch from traditional cigarettes and that any potential risks to youth are outweighed by the benefits to adults.

Toxicity Concerns with Certain Flavors

A key worry centers around the potential toxicity of certain flavor chemicals. Sven Jordt, a professor at Duke University School of Medicine researching tobacco products, expressed particular concern about spice flavors like cinnamon and clove. “Cinnamon and clove in particular, are “among the most toxic flavor chemicals that have been identified in e-cigarettes,” he said. These flavors, he explained, can pose significant health risks when inhaled.

Past issues with cinnamon-flavored vapes involved the melting of plastic components in some devices, potentially leading to the inhalation of harmful substances. Eugenol, found in clove flavors, acts as a local anesthetic, potentially allowing users to inhale larger amounts of vapor. Vanilla flavoring has also been linked to increased dopamine release in the brain, potentially enhancing the addictive potential of e-cigarettes, according to research.

The Balancing Act: Harm Reduction vs. Youth Prevention

The FDA’s consideration of more flavors reflects a broader debate within public health: balancing the potential for e-cigarettes as a harm reduction tool for adult smokers with the require to prevent youth addiction. Many researchers believe e-cigarettes have potential as a tool to help people quit smoking, but preventing teen uptake remains a critical priority.

The agency requires manufacturers seeking approval for flavored products to provide evidence that those flavors are more effective at helping smokers switch than tobacco flavors and that the benefits for adults outweigh the risks to young people. Benjamin Chaffee, a professor at the University of California San Francisco Center for Tobacco Control, Research, and Education, noted via email that meeting this standard “could be a difficult needle to thread.”

Industry Response and Regulatory Challenges

The proposed guidance has drawn mixed reactions from the vaping industry. Jim McCarthy, a spokesperson for the American Vapor Manufacturers, criticized the guidance as “more arbitrary” and argued that manufacturers would need to invest millions in longitudinal studies to meet the FDA’s requirements. Reynolds American, however, argued the FDA should go further, suggesting that offering a wider range of flavors beyond tobacco and menthol would be the most effective way to reduce cigarette use.

Currently, only 39 e-cigarette products from brands like Juul, Logic, NJOY, and Vuse have been authorized for sale by the FDA. The vast majority of e-cigarettes sold in the U.S. Remain illegal, readily available in gas stations, smoke shops, and online retailers. This lack of enforcement has been a longstanding concern for public health advocates.

Concerns About Industry Influence and Shifting Priorities

Some advocates worry the FDA is succumbing to pressure from the tobacco and vaping industry. Dennis Henigan, vice president for legal and regulatory affairs at the Campaign for Tobacco-Free Kids, expressed puzzlement and concern over the apparent shift in approach. He pointed to the tobacco industry’s significant political donations, including contributions to former President Trump’s campaigns, and the withdrawal of proposed FDA rules banning menthol in cigarettes and reducing nicotine levels.

The recent authorization of Zyn nicotine pouches in flavors like coffee, mint, and citrus has also raised concerns about a broader trend toward authorizing flavored nicotine products. The FDA did not respond to a request for comment on these issues.

The Role of Flavors in Attracting Youth and Adult Smokers

Whereas some research suggests a wider range of flavors may appeal to adult smokers, experts caution that flavors can also counteract the unpleasant sensory effects of nicotine, potentially making e-cigarettes more appealing to young people. Mint, for example, remains a popular flavor choice among youth, and flavors like cinnamon and vanilla are widely enjoyed by teenagers.

The FDA’s draft guidance is open for public comment for the next 60 days. The agency will then review the feedback and decide whether to finalize the guidance. The outcome of this process will have significant implications for the future of the e-cigarette market and public health efforts to reduce both smoking and youth vaping rates.

The situation is further complicated by the booming nicotine pouch market and the recent changes in FDA priorities. As UCSF’s Chaffee set it, “Aggressively combatting tobacco smoking does not appear to be a priority presently.”
