In Cannes, municipal police have begun deploying nitrous oxide detectors to enhance road safety. These devices, which function similarly to breathalyzers, aim to identify drivers who have consumed the gas, often referred to as ‘laughing gas.’ While the technology is not yet officially certified, the city is utilizing a 2025 municipal decree prohibiting the sale of nitrous oxide canisters to issue citations and prioritize user safety.

Following these local efforts, French authorities have updated the Highway Code via article L237-1 to address the misuse of the substance. The new legal measures allow criminal courts to penalize drivers for nitrous oxide consumption without the need for laboratory analysis, a process previously required due to the substance’s rapid dissipation from the body. This legislative change mirrors existing laws regarding alcohol intoxication to combat the neurological and cardiovascular risks associated with recreational use while driving.
