HB 1933, known as the "Maddix Bias Act," regulates the use and sale of nitrous oxide in Oklahoma. It prohibits individuals from inhaling, ingesting, or possessing nitrous oxide for recreational intoxication, and makes it unlawful to sell or transfer it for such purposes. Violations carry penalties including fines, imprisonment, and potential drug rehabilitation. The bill also makes it a misdemeanor for adults to sell drug paraphernalia specifically for nitrous oxide inhalation to minors. Several exemptions are provided for medical, dental, automotive, industrial, and specific culinary applications of nitrous oxide.
