Neighbourhood Support – Tackling the rise of “nangs”

You may have noticed small, silver metal canisters discarded in local parks, beach carparks and on the streets. Known as “nangs,” “nos,” or laughing gas, these canisters of nitrous oxide are a growing concern for Police and the Ministry of Health.

While nitrous oxide has legitimate uses in catering (such as whipping cream), it is increasingly being misused for a “quick high.” Policing assistant commissioner Tusha Penny warns that this is a “clear and grave” risk on our roads.

Inhaling the gas causes near-instant dizziness, confusion, and blackouts. Police have reported cases of drivers “playing chicken” with their own consciousness while driving. 

Police are currently engaging with retailers across the country to remind them of their obligations. Under the Psychoactive Substances Act, it is illegal to sell nitrous oxide for recreational use.

Local dairies, vape shops, and convenience stores are being urged to question bulk sales, especially if there isn’t a clear catering purpose, and to store canisters behind the counter rather than on open shelves.

However, it doesn’t just cause a “short-term” buzz as the physiological toll is significant. The Ministry of Health’s chief medical officer, Dr Joe Bourne, says when inhaled, the gas pushes oxygen out of the lungs and bloodstream, and inhaling the gas can have devastating long-term effects.

“Separately we know that heavy, frequent, or chronic use can cause nerve damage, leading to weakness, numbness, and long-term problems with movement or coordination,” says Dr Bourne. Symptoms often begin as “jelly-like” legs or persistent tingling, but in severe cases, users can lose the ability to walk or work entirely.

At Hibiscus Coast Neighbourhood Support, we believe a connected community is a safe community. Here is how you can help:

Report hotspots: If you notice an influx of discarded silver canisters in a specific local park or carpark, report it to the Council or via the Police 105 non-emergency line. This helps Police identify where engagement is needed. Report dangerous driving: If you see a driver inhaling from a balloon or canister, call 111 immediately.

Talk to your teens: Ensure young people understand that “nangs” are not a harmless party drug – they are a psychoactive substance with long-term health and legal risks. Support Local Business: Encourage our local shop owners to follow the new Police guidelines. Let’s keep our Coast roads and parks safe for everyone.
