A debate in the European Parliament on Thursday laid bare growing concern across Europe over the recreational misuse of nitrous oxide (N₂O) — the substance commonly known as “laughing gas” — with lawmakers warning it is increasingly harming young people, leaving discarded canisters littering cities and fuelling calls for stronger EU-level restrictions.
Speaking on behalf of the European Commission, Wopke Hoekstra warned that what was once a specialised industrial and medical product is increasingly being used recreationally across the bloc.
“Nitrous oxide is originally intended for several industrial and medical applications. However, the abuse of it as a recreational drug has been increasing across the European Union, leading to severe health effects for persons abusing the substance, but also for victims of road accidents caused under the influence of the substance. The Commission takes this issue very seriously and is committed to quickly finding effective solutions to address it, in line with our shared goal of protecting the health and well-being of our European citizens.”
Big enough to cause major damage
Commissioner Hoekstra pointed in particular to the emergence of large industrial canisters deliberately marketed for misuse, arguing the scale of the problem has outgrown national responses.
“It is clear that large canisters of the substance are being specifically placed on the market for the purpose of enabling abuse. Such large canisters containing up to several kilogrammes of the substance are labelled as allegedly serving food purposes only.
However, there is no evidence whatsoever to suggest that these large canisters serve legitimate food purposes. The placing on the market of these canisters is a major concern and we must acknowledge and tackle the significant harm it causes.”

Several EU countries have already tightened national laws, but Mr Hoekstra argued that the cross-border nature of the market means enforcement gaps remain.
“A number of member states have already taken steps to address the issue through their national drug legislation, and the Commission very much welcomes these efforts. However, even in those member states the sales of these illegal and falsely labelled canisters seem to continue. This highlights the need for more effective enforcement and cooperation, but also that the abuse of nitrous oxide is a Union-wide issue which requires a Union-wide approach.”
Under existing EU chemicals legislation, nitrous oxide has recently been classified as reprotoxic, triggering a procedure that could see large canisters banned from sale to the general public from February 2027, while small culinary cartridges would remain permitted for legitimate uses.
Parliament raises alarm over youth harm
In Parliament, MEPs from across the political spectrum described a rapidly growing problem — particularly among young people attracted by the drug’s accessibility and perception as harmless.
Alex Agius Saliba (S&D/MLT) warned that the image of nitrous oxide as a trivial party substance masks serious medical risks.
“When we speak about nitrous oxide, many people still think of something harmless — a chocolate mousse, a painless disappointment, a brief moment of fun. But laughing gas is not a laughing matter.
Young people across Europe are inhaling the substance in ways never intended to be used, and the consequences can be severe, such as loss of consciousness, damage to the nervous system, and even spinal injuries in repeated use.”
He pointed to cases across Europe — including deaths and paralysis — as evidence the threat is no longer theoretical.
“A 17-year-old girl in France found lifeless among dozens of canisters. A young man killed by a driver under the influence of the substance. A 19-year-old girl in Malta temporarily paralysed for hours. This should be a reminder that what may appear harmless can quickly become harmful.”
MEPs also highlighted the visible environmental footprint of the trend, with discarded cartridges appearing in parks, nightlife districts and residential streets.
One speaker described how thousands of canisters now appear across European cities, a symbol of a growing recreational drug culture fuelled by easy online sales and industrial-scale supply. Others warned that repeated exposure can lead to serious neurological damage, citing cases of spinal cord degeneration among young users in several EU countries.
Calls for an EU ban — and resistance
Some lawmakers argued the evidence now justifies an outright ban on public sales.
Dominique Bilde (FRA), an MEP on the political far-right, framed the issue starkly.
“Some continue to call it laughing gas. There is nothing prosaic about it; there are tragedies; there are lives that are broken and families thrown into grief that cannot be repaired. The consequences are known: psychiatric problems, death, paralysis. The danger of these substances is no longer something that needs to be proven.”
He argued that national restrictions alone cannot work while products continue to move freely across the EU’s single market.
“So long as there is free movement of these products or they are sold online, they will cross borders easily. That is why we have called on the Commission to act.
When a substance presents an unacceptable risk for human health, the European Union must act.”
Yet not all MEPs supported an EU-wide prohibition, with one member of the Europe of Sovereign Nations group arguing that banning the substance outright would go too far.
“A general ban on the sale of nitrous oxide is less easy to justify. Individuals should be able to decide whether they want to buy nitrous oxide or not.
We shouldn’t be speaking on behalf of citizens at national or European level. We don’t need any more state bans.”
For many lawmakers in Strasbourg, the message was clear: nitrous oxide may still be known as laughing gas, but the consequences are anything but a laughing matter.
