The proposed bill introduces a new section to chapter 69.50 RCW that criminalizes the sale, distribution, or administration of nitrous oxide and related devices, classifying such actions as gross misdemeanors. Specifically, it targets individuals who sell or distribute canisters, tanks, or devices containing nitrous oxide, flavored nitrous oxide, or a chemical compound mixed with nitrous oxide. However, the bill includes several exemptions: it does not apply to licensed medical, veterinary, or dental practitioners administering nitrous oxide for professional care, nor does it affect the sale of nitrous oxide in food products as a propellant, its use in manufacturing processes, or its application for automotive purposes.

The bill defines "nitrous oxide" to encompass various terms, including N2O and laughing gas. By establishing these regulations, the legislation aims to address concerns regarding the misuse of nitrous oxide while ensuring that legitimate medical and industrial uses are not hindered.
