Laughing gas possession becomes illegal

Possession of nitrous oxide, also known as NOS, has become a criminal offence in the UK.

Now categorised as a class C drug, possession of laughing gas for its “psychoactive effects” will carry a sentence of up to two years in prison.

The government says the ban will combat anti-social behaviour and reduce damage to users’ health.

Experts previously warned against a ban saying it would be disproportionate to the level of harm it causes.

Nitrous oxide is regularly used as a painkiller in medicine and dentistry. When mixed with oxygen, it is known as “gas and air”, which can help reduce pain during childbirth.

But it is also one of the most commonly used recreational drugs by 16 to 24-year-olds. It causes short-term euphoria but can damage the nervous system.

Under the new rules, those found in unlawful possession of the drug could now face a prison sentence or unlimited fine, with up to 14 years for supply or production.
