The Federal Picture
Kava is legal at the federal level. It's not scheduled under the Controlled Substances Act, and it's sold nationwide as a dietary supplement. The DEA lists kava as a "drug of concern," a monitoring designation reflecting its psychoactive properties, not a legal restriction on possession or sale.
The complication sits one level down: the FDA doesn't currently recognize kava as Generally Recognized As Safe (GRAS) for use in conventional foods and beverages, a status separate from its legality as a supplement. This gap, supplement yes, GRAS food ingredient no, is exactly what some cities have used to restrict kava bars specifically, even though the plant and supplement products themselves remain legal.
New York: The Clearest Recent Example
In March 2025, New York State issued a regulation classifying steeped kava beverages as an unapproved food additive, based partly on a 2020 FDA memorandum that found insufficient toxicological data to establish kava as safe for indiscriminate beverage use. New York City subsequently enforced this against kava cafés, issuing summonses for violating food adulteration rules.
One affected business, Kavasutra, sued, arguing that kava mixed only with water should count as a single-ingredient food, not a food additive requiring separate approval. On August 7, 2025, a federal judge upheld the city's position, ruling that adding kava to water changes water's chemical composition in a way that makes it a food additive under federal law, since it introduces kavalactones, compounds with documented hepatotoxic properties in certain contexts.
It's worth being precise about what this ruling actually restricts: it doesn't ban kava itself, kava supplements, or personal possession and use. It specifically prevents commercial food establishments in New York City from selling prepared kava drinks. This is a food-service regulation, not a plant ban.
Other States and Cities
No US state bans kava outright at the possession level. Wisconsin is generally cited as having the strictest commercial restriction, with state health department rules restricting kava sale and distribution, though personal possession reportedly remains legal there. A handful of other jurisdictions have imposed narrower local rules, such as county-level permitting requirements or, in some cases, restrictions on kava served alongside alcohol at bars. Hawaii and Michigan have moved in the opposite direction, each separately recognizing traditionally prepared, water-based kava as GRAS at the state level, distinct from the federal FDA position.
This Is an Actively Evolving Area
Worth being direct about this: US kava regulation is genuinely unsettled right now. Different signals, state-level GRAS recognitions in Hawaii and Michigan, a restrictive New York State regulation and court ruling, and separate federal-level food-status developments, are pointing in different directions at the same time. This isn't a sign of sloppy reporting, it reflects an actual, live regulatory conflict playing out in real time. If you're considering opening or operating a kava business, check current state and city rules directly rather than relying on any single source, including this one.
