New Zealand tightens nitrous oxide regulations under the Psychoactive Substances Act due to rising recreational use and health concerns.

New Zealand's government is tightening regulations on nitrous oxide, also known as laughing gas, due to rising recreational use. It now classifies the substance under the Psychoactive Substances Act, imposing severe penalties for selling or possessing it for personal use—up to two years in prison or substantial fines. This move addresses public health concerns linked to nitrous oxide abuse, which is also increasing in countries like Australia and the UK.
