Flavored vapes are restricted in the United States primarily because of their outsized appeal to teenagers. Federal enforcement began in February 2020 after back-to-back years of record-breaking youth e-cigarette use, and the regulatory picture has only tightened since then. The story involves a mix of federal policy, state laws, health concerns about flavoring chemicals, and a review process that most vape manufacturers have failed to pass.
The Youth Vaping Surge That Triggered Action
The FDA had been aware of e-cigarettes for years but dramatically shifted its stance after national survey data showed youth vaping hitting new highs in both 2018 and 2019. The numbers were hard to ignore: flavored products were the overwhelming preference among young users. In the most recent National Youth Tobacco Survey, 87.6% of middle and high school students who vaped used flavored products, with fruit flavors leading the pack, followed by candy and dessert flavors, then mint and menthol.
Research had long established that flavors increase the appeal of tobacco products to young people, but cartridge-based devices like Juul made the problem worse. These products were easy to conceal, could be used discreetly in classrooms and bathrooms, often contained high nicotine concentrations, and were manufactured at massive scale. The combination of kid-friendly flavors and a sleek, hideable design created what regulators viewed as a public health emergency.
What the FDA Actually Banned
Starting February 6, 2020, the FDA began prioritizing enforcement against flavored cartridge-based e-cigarettes, with the exception of tobacco and menthol flavors. This wasn’t a blanket ban on all flavored vapes. It specifically targeted prefilled cartridge systems. The agency also flagged any e-cigarette product marketed to minors or sold without adequate age-verification measures.
A second, broader deadline hit on September 9, 2020. After that date, every e-cigarette on the U.S. market needed to have a premarket application on file with the FDA or face enforcement action. This application process, known as PMTA (premarket tobacco product application), became the mechanism that effectively removed tens of thousands of flavored products from legal sale.
Why Almost No Flavored Vapes Passed FDA Review
The PMTA standard requires manufacturers to prove that their product is “appropriate for the protection of the public health.” For flavored e-cigarettes, that means demonstrating that the benefit to adult smokers trying to quit outweighs the well-documented risk of attracting young users. This is a high bar, and most companies couldn’t clear it.
In one wave of decisions, the FDA denied marketing applications for roughly 55,000 flavored e-cigarette products from just three companies. The reason was consistent: the applicants lacked sufficient evidence that their flavored products helped adult smokers enough to justify the youth appeal. The agency indicated that the kind of evidence it expected would typically come from randomized controlled trials or long-term studies tracking smokers over time. Most applicants submitted nothing close to that.
Today, only 41 e-cigarettes are authorized for legal sale in the United States, and the FDA is clear that authorization does not mean “safe” or “FDA approved.” Every authorized product still carries health risks.
Health Concerns Specific to Flavoring Chemicals
The regulatory argument centers on youth appeal, but there are also direct health concerns about the chemicals that create vape flavors. These compounds may be safe to eat, but inhaling them is a different story.
The most well-known example is diacetyl, a buttery flavoring chemical linked to “popcorn lung” (bronchiolitis obliterans) after workers at a microwave popcorn factory developed severe, irreversible lung damage from breathing it in. A study testing 51 e-cigarette flavors found diacetyl in 39 of them. A related compound called 2,3-pentanedione, which carries similar respiratory risks, showed up in 23. At least one flavoring chemical was detected in 47 of the 51 products tested. Popcorn lung can become so severe that a lung transplant is the only remaining option.
Beyond the lungs, lab research shows that common flavoring compounds can damage blood vessels. When cells lining blood vessels were exposed to vanillin, cinnamaldehyde (cinnamon flavor), eugenol (clove flavor), and menthol, they produced less nitric oxide, a molecule essential for keeping blood vessels relaxed and healthy. These same compounds triggered inflammatory signals even at very low concentrations. The damage occurred independently of nicotine, meaning the flavoring additives themselves pose cardiovascular risks.
How Marketing Played a Role
Regulators and public health groups pointed to e-cigarette marketing as evidence that flavored products were designed with young people in mind, regardless of what manufacturers claimed. Flavor names like “the cupcake man,” “smoothy,” and “vanilla cupcake” were paired with colorful, candy-like packaging. In one study, 93.7% of young participants said an ad for a cupcake-flavored e-liquid targeted an audience younger than themselves. Over half felt that ads for cherry, smoothie, vanilla cupcake, and caramel cappuccino flavors were aimed at people their age. The e-cigarette industry maintained these products were for adult smokers, but the visual evidence told a different story.
State Laws Go Further Than Federal Policy
Six states have enacted their own restrictions on flavored tobacco products, and several go well beyond what the FDA enforces at the federal level.
- California restricts sale of nearly all flavored tobacco products, with narrow exceptions for premium cigars and hookah tobacco sold in adult-only stores.
- Massachusetts bans all flavored tobacco products, with a limited exception for flavored e-cigarettes consumed on-site at licensed smoking bars.
- New Jersey and New York restrict all flavored e-cigarettes, though New York allows the handful of menthol e-cigarettes that have received FDA authorization.
- Rhode Island and Utah ban flavored e-cigarettes but exempt menthol.
Numerous cities and counties have passed their own flavor restrictions as well, creating a patchwork of rules that varies significantly by location.
The Disposable Vape Problem
The FDA’s 2020 enforcement focused on cartridge-based systems, which left disposable flavored vapes in a gray area. Manufacturers quickly exploited this gap, flooding the market with brightly packaged, single-use devices in every flavor imaginable. Most of these products are on the market illegally, having never received FDA authorization, but enforcement has struggled to keep pace with the sheer volume of products and brands.
Other countries are tackling this differently. England passed regulations banning the supply of all single-use vapes starting June 1, 2025, defining them as any device that is not refillable, not rechargeable, or both.
Do Flavor Bans Push Adults Back to Cigarettes?
One common concern is that restricting flavored vapes might drive adult smokers who use e-cigarettes as a quitting tool back to traditional cigarettes. Research from three U.S. states with flavor bans suggests this fear is largely unfounded. Only 8.3% of adult e-cigarette users stopped vaping after bans took effect, and those most likely to quit were nonsmokers and former smokers rather than current smokers. Most users simply switched to unflavored e-cigarettes. That shift may actually carry a health benefit, since removing flavor additives reduces the toxicity of the inhaled aerosol.
