U.S. health officials have raised concerns about a rise in injuries linked to nitrous oxide misuse, often called laughing gas. While this gas is typically used as a sedative in dental offices and hospitals, some people now misuse it to feel euphoric. Recently, flavored nitrous oxide products like Cosmic Gas, Galaxy Gas, and MassGass have become popular. These products, often sold in colorful packaging at gas stations, vape shops, and online stores, have drawn the attention of health authorities.

The Food and Drug Administration (FDA) has warned that inhaling nitrous oxide can cause dangerously low blood pressure, which may lead to unconsciousness and serious harm. Poison control centers have reported more emergency calls involving people who collapsed after using the gas improperly. The FDA believes this increase is linked to flavored nitrous oxide products sold for cooking, despite warnings not to inhale them. Social media videos have also contributed to this trend by showing young people misusing the gas. Although some U.S. states have introduced age restrictions on nitrous oxide sales, there are no nationwide rules limiting access. The FDA continues to regulate nitrous oxide as a medical product in healthcare settings, but its control over cooking-related products is unclear. Health officials stress the importance of raising public awareness about the serious risks of nitrous oxide misuse.
