The sale and possession of laughing gas will be banned under plans to crack down on anti-social behaviour, Sky News understands.
Ministers want to revise drug misuse laws to allow people found with nitrous oxide gas in public to be prosecuted.
The party drug, commonly known as laughing gas, is the second most commonly used drug among 16 to 24-year-olds in England after cannabis and there are concerns about health problems caused by its usage.

“There is a clear view that we have to act,” a Home Office source said.
“There is a clear link between the use of nitrous oxide and anti-social behaviour and this is a top priority for the government.”
Only those with a “legitimate reason” would be exempt from the ban, such as chefs who use it in products liked whipped cream or doctors using it for pain relief.

Those with a legitimate reason to possess the drug may be required to obtain a licence, though ministers are said to be keen on “avoiding bureaucracy”, the source said.
Current legislation bans the knowing or reckless supply of nitrous oxide for inhalation, but there have been calls for a ban on all direct consumer sales as part of a tightening up of the law.
The substance is already being reviewed by the independent Advisory Council on the Misuse of Drugs, but policing minister Chris Philp wants this to be fast-tracked to April with the hope a formal announcement could be made as part of the government’s anti-social behaviour strategy due later this year.

The punishment for being caught is likely to be similar to sentences for class C drugs, with those in possession facing up to two years in prison or an unlimited fine and those supplying the drug facing a maximum 14-year sentence.
Prime Minister Rishi Sunak wants to speed up a crackdown as he believes tackling anti-social behaviour is key to winning the next election, according to The Times which first reported on the story.
The newspaper said Home Secretary Suella Braverman also backs the move and has privately been pushing for more enforcement action on low-level drugs.
Nitrous oxide is known as laughing gas as use of the drug can cause fits of giggles, but a top neurologist told Sky News in December it is “no joke”.
Dr David Nicholl, clinical lead for neurology at Sandwell and West Birmingham NHS Trust, said misuse of the substance is currently the most common cause for emergency admissions to the neurology ward.
“People come into hospital off their legs, difficulty walking, presenting with tingling in the hands and feet, slurred speech and more rarely seizures,” he warned.
“I’ve even spoken to one ophthalmologist colleague who has seen a patient who went blind, but that was secondary to hypoxia caused by inhaling nitrous oxide.”
