The proposed bill aims to regulate the sale of nitrous oxide products in Massachusetts to protect public health and safety while allowing legitimate uses in culinary, medical, dental, and industrial contexts. It defines "nitrous oxide product" and establishes "authorized sellers" as licensed culinary or medical supply retailers. The bill restricts the sale of nitrous oxide products to authorized sellers only, prohibits sales to individuals under 21 years of age, and mandates that these products be kept out of public view, only available upon direct request.

Additionally, the bill outlines enforcement measures and penalties for violations, including fines that escalate with repeated offenses and the potential for license suspension or revocation. Authorized sellers are required to maintain sales records for at least one year and display a warning sign regarding the prohibition of sales to individuals under 21 and the dangers of recreational inhalation. The bill also allows municipalities to implement stricter regulations if desired.
