Known for its euphoric properties, nitrous oxide, often called “laughing gas”, is the subject of a worrying diversion from its medical use. This gas, initially used in anesthesia or dentistry, is now consumed for recreational purposes, particularly by young people.
From the first use, the side effects can be serious: asphyxiation, loss of consciousness or burns due to improper handling. Repeated consumption exposes one to much more serious complications, such as neurological disorders, hematological damage or addictions. Beyond the health dangers, this phenomenon also poses problems of urban sanitation, with the proliferation of empty cartridges, and public peace.
Faced with this alarming situation, the City of Lyon has decided to take firm measures. Mohamed Chihi, deputy mayor in charge of security, signed an order on November 25, 2024 prohibiting the sale, possession and use of nitrous oxide cartridges in public spaces. This ban aims to protect the health of residents while guaranteeing a more peaceful living environment.
Lyon Metropolis services collected more than 7 tonnes of empty cylinders in 2023. This figure highlights the full extent of the problem. A national survey also shows that 11.7% of young people aged 15 to 24 have already consumed this gas, a figure that is constantly increasing.
However, the ban is only one part of the municipal response. Prevention plays a central role in this approach. In partnership with the Hospices Civils de Lyon, an innovative teleconsultation system dedicated to users of nitrous oxide has been set up. In addition, an information leaflet co-produced with the Regional Health Agency and the addictovigilance center is widely distributed to raise awareness among young people.
In 2023, more than 7 tonnes of empty nitrous oxide cartridges were collected in the city of Lyon, and 25 tonnes throughout the metropolis. Violations of this decree will be punishable by a fine of 150 euros.
By combining prohibition and prevention, the City of Lyon is showing its determination to act against this scourge. Any offender now faces legal sanctions, while support tools are offered to reduce the risks associated with this dangerous practice.
