FDA issues guidance on flavored vapes, sparking public health discussions
The U.S. Food and Drug Administration (FDA) has released new draft guidance outlining the potential authorization of flavored e-cigarettes, opening the door for products in flavors like coffee, mint, and cinnamon. This move has sparked widespread debate among public health experts, tobacco researchers, and anti-tobacco advocates, with concerns ranging from youth vaping rates to the toxicity of certain flavor additives.
Balancing Harm Reduction and Youth Protection
The FDA’s draft guidance highlights the tension between two competing public health priorities: supporting adult smokers who want to quit combustible cigarettes and protecting teenagers from the risks of nicotine addiction. Currently, the FDA has only authorized e-cigarettes in tobacco and menthol flavors, aiming to limit the accessibility of sweet and fruity flavors that fueled the youth vaping epidemic of the late 2010s.
However, the new guidance suggests that flavors viewed as more "sophisticated", such as coffee or mint, could now be considered for approval. According to the FDA, manufacturers seeking authorization for such products would need to demonstrate that these flavors help adult smokers transition from traditional cigarettes more effectively than tobacco flavors and that the benefits outweigh potential risks to youth.
"If the FDA imposes a high bar for evidence, that could be a difficult needle to thread", said Benjamin Chaffee, a professor at the University of California San Francisco Center for Tobacco Control, Research, and Education.

Concerns Over Flavored Vape Toxicity
Some public health experts have raised alarms over the potential toxicity of certain flavors mentioned in the FDA’s draft. "What I’m really concerned about, as someone looking at the toxicity of flavors, is that they want to endorse spice flavors", said Sven Jordt, a professor at the Duke University School of Medicine who researches tobacco products. Jordt identified cinnamon and clove as particularly hazardous, noting that they are "among the most toxic flavor chemicals that have been identified in e-cigarettes."
Suchitra Krishnan-Sarin, a psychiatry professor at the Yale University School of Medicine, echoed these concerns, citing earlier issues with high levels of cinnamon in vape liquids. "Many e-cigarette products that existed on the market earlier had very high levels of cinnamon, and cinnamon is known to be a toxicant when inhaled", she explained. Manufacturers at the time even recommended using glass tanks because the cinnamon liquids could melt plastic components, which Jordt pointed out "will also melt your lung."
Other flavoring agents, such as eugenol in clove and vanillin in vanilla, are also under scrutiny. Eugenol acts as a local anesthetic, making it easier to inhale more vapor, while vanillin has been shown to promote dopamine release, potentially increasing the addictive appeal of flavored vapes.
Industry and Advocacy Reactions
The FDA’s draft has drawn mixed reactions from industry representatives and public health advocacy groups. Jim McCarthy, a spokesperson for the American Vapor Manufacturers trade group, criticized the guidelines as "more arbitrary, imaginary, unreliable double-talk from an agency that has been misleading the public about safer nicotine products shamelessly for years."
Meanwhile, Luis Pinto, a spokesperson for Reynolds American, called on the FDA to go further, stating that "the biggest opportunity to reduce cigarette use is by giving adult smokers appealing flavor options beyond tobacco and menthol."
On the other hand, anti-tobacco advocates, such as Dennis Henigan of the Campaign for Tobacco-Free Kids, expressed dismay over the FDA’s apparent shift in approach. "We see no good reason for FDA to deviate from how it has been assessing flavored e-cigarettes", said Henigan. "We’re both puzzled and troubled by this apparent shift in approach."
Implications for Youth Vaping
Despite the FDA’s ongoing efforts to curb youth vaping, experts worry that introducing flavors like mint or coffee could reignite the issue. Mint was the third-most popular flavor among youth e-cigarette users in the 2024 National Youth Tobacco Use survey, following fruit and candy. Further, Jordt argued that flavors like coffee could appeal to young people already drawn to products like iced coffee drinks and cinnamon gum.
"Are we repeating history?" Krishnan-Sarin asked, pointing to past cycles of underage vaping fueled by flavored products. Public health experts also noted that enforcement against unauthorized flavored vapes has likely contributed to the significant decline in youth vaping, which fell to 6% in 2024 compared to a peak of 20% in 2019.
A Complex Path Forward
The FDA’s draft guidance remains open for public comment for the next 60 days and has not yet been finalized. Experts like UCSF’s Chaffee have questioned whether the FDA’s current priorities align with the long-term goal of reducing tobacco-related harm. "Aggressively combatting tobacco smoking does not appear to be a priority presently", he said.
As the debate continues, the FDA maintains that its approach reflects a commitment to public health. An FDA spokesperson stated, "When it comes to e-cigarettes, that means authorizing those products that prove they can help adults who smoke – while remaining vigilant in our protection of youth from the harms of tobacco products."
The final decision on flavored vape authorizations will likely shape the future of harm reduction policies and highlight the ongoing challenges of balancing adult smoking cessation tools with youth prevention efforts. For now, stakeholders across the spectrum await further clarity on how the FDA will navigate this contentious issue.
