Are Smelling Salts Legal? Sports and Sales Rules Explained

Part of our series: Smelling Salts — The Complete Guide.

The short answer

In the United States, ammonia inhalants are legal to buy and sell. They are not a controlled substance, no federal ban is in force, and no state has been identified that prohibits or age-gates their retail sale by name.

What exists instead is a marketing problem at federal level, a patchwork of general inhalant statutes at state level that mostly do not reach ammonia, and a set of private rules — sports bodies and payment companies — that are not law at all but shape the category more visibly than the law does.

This is general information current as of our most recent regulatory scan. It is not legal advice, and if you need a position on your specific situation you need a lawyer, not a retailer's blog.

Federal law

Not scheduled. Ammonia inhalants are not controlled substances under the DEA schedules. Possession and purchase are not federal offences.

But not approved either. The FDA's position, resting on a proposed rule from 2008 (73 FR 34895, Docket FDA-2008-N-0297), is that ammonia in a product labelled with claims or directions for use as a reflex stimulant is either not generally recognised as safe and effective, or is misbranded. On 6 August 2024 the agency issued a consumer alert on unapproved inhalants marketed for alertness and energy, and between 2023 and 2024 it issued warning letters to seven companies in the category.

The distinction that matters: the enforcement has been aimed at sellers, not buyers, and at claims, not at the product. Nobody has been pursued for owning a bottle. Companies have been pursued for how they described one. The full record is in Are Smelling Salts Bad for You? What the FDA Actually Says.

Other federal agencies. No smelling-salts-specific rule, recall or guidance has been located from the Consumer Product Safety Commission, and no category-specific action from the FTC — though the FTC's general substantiation rules for health and performance claims apply to anyone making them.

State law

Here is a correction worth making, because it is repeated constantly in trade coverage and on forums.

New York Public Health Law § 3380 does not cover smelling salts. The statute is frequently cited as though it did. It defines hazardous inhalants as amyl nitrite, isoamyl nitrite, butyl nitrite, isobutyl nitrite, pentyl nitrite "or any other alkyl nitrite compound." Ammonia is not in that list. The section's separate under-21 sale prohibition covers nitrous oxide, not ammonia. Current as of 1 January 2026.

More broadly: roughly two dozen states restrict the use, possession, sale or distribution of inhalants in general. Those statutes are typically written around solvents and nitrites and usually carry an intent-to-intoxicate element. They are not written around ammonia inhalants sold for athletic use.

No state has been identified that bans or age-gates the retail sale of ammonia smelling salts by name. We monitor this monthly, because it is the area most likely to move first — the nitrous oxide precedent shows how quickly an inhalant category can get age-gated once it draws attention.

State law changes. If you are reading this well after publication, check the current position rather than relying on the date on this page.

Sports rules — private, not legal

Governing bodies set their own rules and those rules are not law. Breaking one costs you a competition result, not a criminal record.

The NFL, 2025. The league instructed its 32 clubs that they may no longer administer ammonia in any form to players, citing the FDA's 2024 warning and the risk of masking concussion symptoms. The NFLPA clarified the scope: teams cannot supply them; players may still use their own.

Powerlifting and strength federations permit them more often than forums suggest, with location rules rather than bans — every position here checked against the federation's current rulebook on 26 August 2026. The IPF permits ammonia but a lifter "shall not... use ammonia within view of the public" (2026 Technical Rulebook). The USPA permits them away from the action: ammonia caps and smelling salts "cannot be used anywhere near the lifting platform or in view of the audience" (Technical Rules §3.16.5). The current USAPL rulebook (v2026.1) does not mention ammonia inhalants at all — and the "not in public view" rule often attributed to USAPL online is the IPF's line, misattributed to a federation that left the IPF in 2021. Where a rulebook is silent, meet directors and venues decide.

Practical rule: check your federation's current rulebook and then check the meet's own rules, because venue and promoter rules stack on top. More in Smelling Salts in Powerlifting and Strength Sports.

Why some retail platforms restrict the category

This one confuses people, because a product that is legal to sell can still be hard to sell online. The reason is that payment acceptance is governed by private contracts, not by law.

Card processors and payment providers publish their own prohibited and restricted business lists. Those lists are contractual terms, and they are typically broader and vaguer than legislation — categories like "products that present a risk to consumer safety" or "pseudo-pharmaceuticals" are written to give a reviewer discretion rather than to define a boundary precisely.

Ammonia inhalants are not named on the major providers' published lists. But a public FDA consumer warning gives a reviewer a straightforward hook to place the category under a general safety clause, and marketing claims give them a second one. The result is that the category tends to be handled case by case rather than banned outright, and a seller's own copy is one of the things being assessed.

That is a large part of why this store exists as a separate storefront, and a large part of why our product pages read the way they do.

What this means if you are buying

• Buying and owning one is legal in the United States as things stand.
• Check your sport's rules if you compete. That is where a real restriction is most likely to affect you.
• Check your state's current position if you are reading this long after publication.
• Treat claims as a warning sign. A seller still promising energy, focus or performance in 2026 is using the exact language seven warning letters cite.
• None of this is a safety clearance. Legal to sell is not the same as safe for you to use. Read How to Use Smelling Salts Safely before you use one.

FAQ

Are smelling salts legal in the US? Yes. They are not a controlled substance and no federal ban on sale is in force.

Are smelling salts illegal in New York? No. NY Public Health Law § 3380 is often cited as covering them, but it lists alkyl nitrites, not ammonia, and its under-21 provision covers nitrous oxide.

Is there an age limit to buy smelling salts? No state has been identified that sets one by name for ammonia inhalants. Individual retailers may apply their own policy.

Are they banned in sport? Not universally. They are not on the WADA Prohibited List; the IPF and USPA permit them with out-of-public-view rules; the current USAPL rulebook is silent. The NFL stopped clubs supplying them in 2025 while players may still use their own. Check your federation's current rulebook, then your meet's own rules.

Why is it hard to buy smelling salts on some platforms? Payment providers apply their own prohibited and restricted business lists, which are contractual rather than legal and are broad enough to cover the category at a reviewer's discretion.
