What the record says

KRS 438.343, created by 2025 Ky. Acts ch. 78, sec. 16 and effective June 27, 2025, provides that a retailer shall not sell, distribute, give away or cause to be sold any device, canister, tank or receptacle that exclusively contains nitrous oxide or a chemical compound mixed with nitrous oxide, and that nitrous oxide 'shall only be available for the uses as authorized by this subsection.' The section does not prohibit sale of medical gases by a wholesaler licensed by the Board of Pharmacy, dental or medical administration, manufacturing or industrial use, 'the possession, use, or sale of nitrous oxide as a propellant in food preparation for restaurant, food service, or houseware products', or automotive use. Retailer penalties are a $2,500 fine for a first citation, $5,000 for a second and up to 30 days in jail for a third, per premises. The section's definition of 'nitrous oxide' also lists butyl nitrite and its isomers. A lawful channel remains for food-propellant, houseware, automotive and industrial uses, so the record is a named retail sale ban with exceptions rather than a total ban. KRS 217.900 separately bars inhaling any volatile substance for intoxication. Nitrous oxide is not on Kentucky’s controlled-substance schedules. No 2026 Regular Session bill or resolution title mentions nitrous oxide. Federal law does not control nitrous oxide (see the federal page).

This section shall not prohibit: (a) The sale or distribution of medical gases that contain nitrous oxide by a wholesaler licensed by the Kentucky Board of Pharmacy; (b) Any person who administers nitrous oxide for the purpose of providing medical or dental care, if administered by a dentist or dental hygienist in accordance with KRS 313.060; (c) The possession or use of nitrous oxide substances by a manufacturer as part of a manufacturing process or industrial operation; (d) The possession, use, or sale of nitrous oxide as a propellant in food preparation for restaurant, food service, or houseware products; or (e) The possession, use, or sale of nitrous oxide for automotive purposes.
