NSW nitrous oxide rules came into force on 5 November 2026. They put tight new limits on how the gas can be sold to the public. It’s widely used as a party drug known as “nangs”. The restrictions sit within the Medicines, Poisons and Therapeutic Goods Regulation 2026. They’re designed to cut the harms linked to recreational misuse while leaving legitimate uses alone.
What the new NSW nitrous oxide rules say
Under the changes, retailers must not:
- sell nitrous oxide to anyone under 18
- sell canisters containing more than 10 grams of nitrous oxide directly to consumers
- sell more than 250 grams of nitrous oxide to one person in a single day
- sell nitrous oxide between 10pm and 5am
- offer same-day delivery
- display nitrous oxide products or packaging where customers can see them.
Who is affected
The rules apply to retailers, wholesalers, online sellers and any other business selling or distributing nitrous oxide in NSW. The legal obligations rest with sellers, but shoppers will notice the difference too. Under-18s can no longer be sold the gas at all. Adults face smaller canisters and a daily limit, and they can’t place late-night or same-day orders.
When it starts
The restrictions took effect on 5 November 2026. A public awareness campaign launched at the same time. It aims to explain the risks to the community and make sure retailers and suppliers are ready to comply.
What it means in practice
Access for food preparation, medical, automotive and industrial purposes remains unchanged. For businesses, the NSW nitrous oxide rules mean a real shift in how the product is stocked, displayed and delivered. Nothing can be on show, there’s no same-day dispatch, and each customer is capped at 250 grams a day.
How the NSW nitrous oxide rules will be enforced
NSW Health will give retailers guidance on what compliance looks like. It can also issue warnings or seize products supplied in breach of the regulation. Businesses and individuals who fail to comply may also face financial penalties. Guidance, a fact sheet and point-of-sale signage are available at health.nsw.gov.au/nitrous.
Why the change matters
The government links nitrous oxide misuse to severe vitamin B12 deficiency, permanent neurological injury and serious mental health effects. It can also cause frostbite, lung injuries, heart abnormalities, asphyxiation and injuries from falls.
Health Minister Ryan Park thanked advocate Sam Bramman for pushing for the change. Bramman says nangs put him into psychosis at 19 and he spent two months in a psychiatric ward. He ran 300km from Sydney to Parliament House to campaign for the new rules. He calls NSW “a strong start” but wants the same rules on sales and delivery right across Australia.
Anyone worried about their own or someone else’s nitrous oxide use can call the Alcohol and Drug Information Service on 1800 250 015, 24 hours a day.
