Health risks of Nitrous Oxide and potential government responses w/ Postdoctoral fellow at the University of Otago, Christchurch, Jai Whelan: 4th May, 2026

Health Minister Simeon Brown last week indicated that he’d like to crack down on the recreational use of Nitrous Oxide, commonly referred to as NOS or Nangs. 

Brown says nitrous oxide is “becoming a serious public health concern”. However, when compared to other recreational drugs in Aotearoa, it seems that the risk factor is relatively low. In addition, nitrous oxide is used for medicinal purposes fairly frequently, meaning its health risks in standard doses are well documented. 

To discuss the effects and risks involved with Nitrous Oxide, and how the government could develop a more holistic response, News Director Castor spoke to Postdoctoral fellow at the University of Otago, Christchurch, Jai Whelan.
