Vaping in the United States: is it legal, and can you bring a vape? (2026)

Yes, for adults. The federal minimum age to buy any tobacco product, including e-cigarettes and e-liquid, is 21. The law was signed on 20 December 2019 and has no exception for military personnel. Since 30 September 2024 retailers have had to check the photo ID of anyone who looks under 30.

What a shop may sell is narrower than what you see in some of them. The FDA says its authorised list holds the "only e-cigarettes that may be lawfully sold in the United States". As of 28 August 2026 that list had 48 products, mostly tobacco and menthol flavours. In May 2026 the FDA authorised its first fruit-flavoured devices, from Glas, for adults 21 and over, sold with an age-verification device, according to press reports. The FDA adds that authorisation does not make a product safe or "FDA approved".

CBP's duty page for visitors mentions cigarettes (200) and cigars (100) and says nothing about vapes, e-liquid, heated tobacco or nicotine products. We found no CBP figure for how many devices, pods or millilitres of e-liquid a traveller may carry, and no statement on what an officer does with one device in a suitcase.

The enforcement we could confirm is aimed at cargo. On 10 September 2025 the FDA and CBP announced the seizure of 4.7 million unauthorised e-cigarette units, worth about US$86.5 million, at Chicago. The FDA's position is that products without a marketing order cannot be legally marketed or distributed. A device bought in Europe or Asia is unlikely to be one of the 48 authorised, so the realistic risk is that a large quantity looks commercial or that an officer takes it. That is our reading, not a CBP statement.

Carry only what you will use on the trip, keep it in your hand luggage, and ask CBP before you fly if you are unsure. The FDA's own traveller guidance says tobacco products for personal use must comply with CBP regulations.

Only if you are 21 or over and the product is lawful where you are. Some states go further than federal law:

• Flavour bans. Tobacco-Free Kids names California, Massachusetts, New Jersey and New York as having statewide bans on flavoured e-cigarette sales, and says it updated that page on 3 September 2026. New York's covers every flavour except tobacco and menthol, according to press. California also bars online sales of flavoured products since 1 January 2025.
• Local bans. Truth Initiative counts 435 jurisdictions and three tribal nations with some restriction on flavoured tobacco as of 31 March 2026, so a city can be stricter than its state.
• Disposables. Many disposable devices are not on the authorised list, which makes them unlawful to sell federally. We do not list shops or brands.

There is no federal rule for public places other than aircraft, so it is a local question. The CDC counted 20 states, plus DC and Puerto Rico, with comprehensive smoke-free indoor air laws that cover e-cigarettes as of 30 September 2024: California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maryland, Massachusetts, Minnesota, Nebraska, New Jersey, New Mexico, New York, North Dakota, Ohio, Oregon, Rhode Island, South Dakota, Utah and Vermont. In the other states, indoor vaping may be legal in some places and banned in others.

Outdoors, vapes are often treated like cigarettes. New York City bans smoking and e-cigarettes in its parks, on beaches and boardwalks and in plazas such as Times Square, with a US$50 ticket listed by NYC Parks (a figure from the 2011 rollout, so treat it as indicative). California bans smoking and vaping on state beaches and in state parks, with a base fine of US$25 that court fees can raise, per press. Las Vegas casino floors are exempt from Nevada's indoor air law, but that exemption was written for smoking; check the venue's own rule before assuming it covers vapes.

On 17 April 2026 the FDA renewed its modified-risk authorisation for five IQOS products: the IQOS 2.4 and 3.0 holders and chargers and the HEETS Amber, Green Menthol and Blue Menthol sticks. Philip Morris says the newer IQOS ILUMA is still under review, and press reports say it is not sold in the US. CBP lists no allowance for heated-tobacco devices, so a Terea stick or ILUMA device in your bag is in the same grey zone as a vape. Which US cities currently stock IQOS is unconfirmed.

In January 2025 the FDA authorised 20 Zyn pouch products, ten flavours at 3 mg and 6 mg, the first nicotine pouches it has authorised. The orders cover those products only. We did not find a CBP rule on carrying pouches into the country.

We found no rule written for vapes in transit. Most international arrivals, including people changing to another flight, clear CBP on arrival, so assume the border position above applies. For where to smoke or vape between flights, check the airport page: Las Vegas Harry Reid, New York JFK and Los Angeles are the largest entries.

TSA allows vaping devices in carry-on bags only, never in checked bags. Guard against accidental activation, keep lithium-ion batteries at or under 100 Wh, and ask your airline whether it limits the number of devices. Using one on board is a federal offence; in June 2021 the FAA proposed a US$10,300 penalty against a passenger who, among other things, used an e-cigarette in the lavatory. The full rules are in can you bring a vape on a plane.
