Oklahoma lawmakers have signed off on a plan to outlaw recreational nitrous oxide, and after a unanimous vote in the state Senate, the proposal is now parked on the governor's desk. Known as the Maddix Bias Act, House Bill 1933 would make it a crime to inhale, ingest, possess, buy or sell nitrous oxide when the purpose is intoxication.
What the bill would ban
As written, HB1933 targets the use or distribution of nitrous oxide when it is intended to induce intoxication and it comes with criminal penalties. Most violations would be misdemeanors, punishable by up to 90 days in jail and fines of as much as $5,000. The bill also treats possession or transfer of more than 16 grams as a separate unlawful-distribution offense and creates tougher penalties for selling paraphernalia to minors, while keeping exemptions for medical, dental, culinary and industrial uses, according to the bill's final text on the Oklahoma Legislature.
Named for a teenager killed in 2024
The measure is named for 18-year-old Maddix Bias, who was killed in a February 2024 crash that investigators say involved a driver impaired by nitrous oxide. His mother has become a leading public face of the push for HB1933. As reported by News On 6, Bias's family has urged lawmakers to close retail loopholes that allow culinary-grade canisters to be marketed and used for getting high instead of their intended purpose.
Lawmakers' reasoning and the vote
Supporters have framed HB1933 as a public-safety tool aimed at heading off what they describe as a growing trend among young people. Sen. Darrell Weaver, one of the bill's key backers, told KOKH that "no family should have to suffer the loss of a loved one" because of impaired driving. The Senate signed off on the bill on April 15 by a 45-0 vote, and legislative trackers show the measure was referred for enrollment before being transmitted toward the governor's desk, according to LegiScan.
What's next
Now that the bill has reached the governor, he can sign it, veto it or let it become law without his signature. The exact timing will depend on what he decides to do. If enacted as written, the measure sets an effective date of November 1, 2025, in the bill's final language on the Oklahoma Legislature, which means the law would kick in on that date if the governor signs or the bill otherwise becomes law.
Legal implications
Although most violations under HB1933 would be misdemeanors, the proposal also spells out potential administrative penalties for retailers and repeat sellers, including possible business-license suspension and increased fines. Courts would be authorized to require rehabilitation as a condition of probation. How all of that plays out will likely depend on real-world enforcement decisions, product labeling practices and ongoing civil litigation over nitrous oxide retail sales, according to legislative language and summaries available from LegiScan.
