Nitrous Oxide Inhalation Prevention Act

The Nitrous Oxide Inhalation Prevention Act establishes new federal regulations to curb the misuse of nitrous oxide while allowing its continued use for legitimate medical, industrial, and automotive purposes. Key provisions include banning flavored products and limiting food-use canisters to 8 grams, alongside strict rules that prohibit packaging with bright colors or cartoon characters and require prominent warning labels on every cartridge. The bill also imposes age restrictions by setting a minimum purchase age of 21, mandates that retailers verify identification and limit sales hours, and restricts wholesalers from selling directly to individual consumers. To support harm reduction efforts, the legislation authorizes funding for grants aimed at education, prevention programs, and training for law enforcement and medical professionals. Non-compliance with these new requirements can result in civil monetary penalties for manufacturers and distributors, or escalating fines and potential sales bans for retailers.
