France may ban 'laughing gas' sale to minors as usage grows

France may soon ban the sale of nitrous oxide capsules - known as “laughing gas” - to minors, as national health body Anses launches a study into the chemical’s increased use and possible neurological side effects.

The gas - or N2O, called le protoxyde d’azote in French - is often sold in small cartridges or canisters, for use in products such as Chantilly cream spray aerosols. The gas is also often used to fill party balloons.

Increasing numbers of young people - especially aged 20-25 - are inhaling the gas, nicknamed “proto”, as it is said to produce a euphoric effect.

French health and safety agency l’Agence Nationale de Sécurité Sanitaire de l'Alimentation, de l'Environnement et du Travail (Anses) has now launched a study into its use and possible side-effects and negative health consequences, based on rising figures reported by national anti-poison centres.

A bill to ban the sale nationwide to minors across France has been approved by the Senate, but it has yet to go before national parliament l’Assemblée Nationale.

Some towns, including Cannes (Alpes-Maritimes), Mulhouse (Haut-Rhin), Arras (Pas-de-Calais) and Évreux (Eure), have already banned the sale of the gas to under 18s.


Symptoms and addiction

Anses toxicologist Cécilia Solal told news service FranceInfo: “The first symptoms that appear are headaches, dizziness, lightheadedness, and loss of balance. We can see them even in people who are experimenting with nitrous oxide for the first time.

“Among more regular consumers, 70% developed neurological symptoms. We can see that even after they stop consuming ‘proto’, patients continue to have these issues.”

The Anses study has shown that the gas can be addictive. It has also been linked to nerve damage and worse.

Ms Solal continued: “Some people show real withdrawal symptoms. There are some people who consume several hundred cartridges a day. So we are no longer talking about a simple celebration [or social] context, and it is very difficult to stop for some patients.”

‘Foggy and tired’

One user, a 25-year-old named Victor, from Paris, told FranceInfo: “We would meet more and more [to take it]. I took a lot when I was at university, in the evenings, was kind of in fashion.”

Another occasional user, Laura, said: “We got hot very quickly, and I got really red very quickly, and afterwards I laughed, but not much more than that. It left me feeling a bit foggy, and three seconds later it was finished.”

An even younger user, Nathan, aged 14, told the news service: “In the moment, it is not something that really worried me, because it didn’t last very long as an effect.

“But at the beginning, I didn’t understand, I was a bit stunned. I could hear little sounds, and I didn’t laugh, because it didn’t make me feel good. It made me feel tired.”
