US vape laws, explained

In December 2019 Congress raised the federal minimum age of sale for all tobacco products from 18 to 21, effective immediately. It covers cigarettes, cigars, cigarillos, hookah tobacco, pipe tobacco, smokeless tobacco, nicotine pouches and e-cigarettes, including zero-nicotine e-liquids sold as tobacco products.

The rule binds retailers, not buyers, at federal level: it is unlawful to sell, and the FDA enforces it through compliance checks and civil money penalties against stores. Whether it is also an offense for a person under 21 to possess is a state question, and states differ — some have purchase-use-possession penalties, others deliberately do not, on the view that penalizing minors undermines enforcement against sellers.

There is no military exemption, no grandfathering of people who were legally buying at 18 before the change, and no exception for tribal land as a matter of federal law, though tribal sovereignty complicates enforcement in practice.

States may set a higher age but not a lower one. In practice none go above 21, but many add their own licensing, signage and ID-check requirements on top.

Since the 2016 deeming rule, e-cigarettes are regulated tobacco products under the Family Smoking Prevention and Tobacco Control Act. Any product that was not on the market before February 2007 — which is all of them — needs a marketing granted order from the FDA before it may lawfully be sold.

The application is a Premarket Tobacco Product Application. The standard is that permitting the product must be 'appropriate for the protection of the public health', assessed at population level: the benefit of adult smokers switching, weighed against the risk of non-smokers and adolescents starting.

The FDA has authorized roughly 45 ENDS products across five brands. Everything else on sale — the entire flavored disposable market — lacks authorization and is illegally marketed in the agency's terms.

Enforcement runs against the supply chain rather than consumers: import alerts and port seizures with Customs and Border Protection, warning letters, civil money penalties, injunctions and seizure actions against manufacturers, distributors and retailers. Buying or possessing an unauthorized vape is not a federal offense for an adult.

A separate 2020 enforcement guidance prioritized action against flavored cartridge-based products other than tobacco and menthol, while explicitly excluding self-contained disposables and open-system e-liquids. That carve-out is the origin of the modern disposable market, and it remains the single most consequential piece of US vape policy.

In 2021 Congress amended the Prevent All Cigarette Trafficking Act to cover ENDS — devices, e-liquids, pods, and any component, part or accessory. The effects are cumulative and severe for online sellers.

The US Postal Service may not deliver vaping products to consumers. The rule took effect in October 2021. A narrow business-to-business exception exists but requires an approved application, and it is not available for consumer orders.

FedEx, UPS and DHL independently stopped carrying vaping products around the same time. That is corporate policy rather than law, but the combined effect is that mainstream shipping is closed to the category, and online sellers use private and regional couriers with adult-signature delivery.

Any seller shipping ENDS in interstate commerce must register with the ATF and with the tobacco tax administrator of every state it ships into, file monthly reports of all shipments to that state, comply with that state's tax and licensing law, verify the buyer's age against a commercial database at purchase, label the package as containing tobacco products, and require an adult signature with ID at delivery.

The practical result for buyers is that legitimate online vape purchasing is slower and more paperwork-heavy than it was, and that a site offering discreet unlabeled shipping with no ID check is telling you it is not complying with federal law.

Everything not covered above is state or local. The categories that actually matter:

Flavor restrictions. Several states prohibit the sale of flavored e-cigarettes, and some extend that to all flavored tobacco including menthol cigarettes. Hundreds of cities and counties have their own, sometimes stricter than the state's. This is the most consequential variation and it has its own page.

Product directories. A growing number of states require that any vapor product sold in the state appear on a state-maintained approved list, typically limited to products with FDA authorization or a pending application. California went further from January 2026 with an Attorney General 'unflavored tobacco list', where only listed products may be sold. Directory laws convert a federal authorization question into a state retail licensing question, which is far easier to enforce.

Taxes. Some states tax by volume of e-liquid, some by wholesale price percentage, some tax open and closed systems at different rates, and some do not tax vapor products at all. Local jurisdictions sometimes add their own.

Retail licensing. Most states require a specific license to sell vapor products, separate from a general tobacco license, with penalties including license suspension for sales to minors.

Public use. Whether you may vape indoors is decided by state clean indoor air acts and local ordinances. Many states that ban indoor smoking include e-cigarettes explicitly; some do not, leaving it to the venue. Federal rules separately ban vaping on all commercial flights and in most federal buildings.

Online sales bans. A handful of states prohibit direct-to-consumer shipment of vapor products entirely, regardless of PACT Act compliance.

Start with your state's department of revenue or tobacco tax administrator for licensing, tax and directory questions — the directory itself, if the state has one, is usually published there.

Check your state department of health or attorney general for flavor restrictions and clean indoor air rules. Attorney general offices publish enforcement guidance that is generally more current than third-party maps.

Check your city and county separately. Local flavor and public-use ordinances are common, frequently stricter than state law, and almost never reflected in national summaries.

For whether a specific product is authorized, use the FDA's marketing orders page rather than any retailer's claim. It is the running record and it is definitive.

Treat commercial vape-retailer 'state law maps' with caution. They are marketing assets, they conflict with each other, and we found substantial disagreement between them on which states ban what. Use them to know a question exists, never as the answer.
