New South Wales is introducing a crackdown on the sale of nitrous oxide, commonly sold as “nangs,” with rules aimed at reducing harm associated with the substance, according to reporting from multiple outlets. The measures include barring sales to people under 18 and restricting trading hours by outlawing sales after 10:00 pm. The reporting frames nitrous oxide as a harmful everyday substance and cites concerns that it is contributing to hospitalisations, particularly among young people. The proposed changes place limits on who can buy the product and when it can be sold, shifting the regulatory approach from open access to tightened controls. While the outlets describe the actions as a crackdown, they do not provide additional operational details such as enforcement agencies, penalties, or the scope of existing regulations beyond the age and time limits. Overall, the coverage agrees that NSW is tightening access to nangs through age restrictions and later-night sales bans.
