Yes, nitrous oxide (whippits) is legal in Missouri for legitimate industrial, medical, and culinary purposes under state law, but its recreational inhalation is prohibited.
Missouri has not criminalized possession of nitrous oxide canisters outright, yet the 2023 Missouri General Assembly amended Section 195.215 RSMo to prohibit their use for intoxication. Local ordinances, such as those enforced by the Kansas City Health Department, now classify recreational inhalation as a public health violation. The Missouri Department of Health and Senior Services (DHSS) monitors compliance, with penalties escalating under the 2026 state budget bill that allocates additional funds to county prosecutors for enforcement. Retailers must verify buyer age (18+) and refrain from selling to minors, aligning with Missouri’s 2024 amendments to the Uniform Controlled Substances Act.
