A 26-year-old man died from suffocation after intentional recreational nitrous oxide use via a full-face gas mask connected to a cream whipper dispenser. He had purchased 300 cream chargers plus a 640g tank online two days before death and had been using 15-20 'nangs' every second day. The coroner found he died from oxygen deprivation caused by both the vitiated atmosphere from nitrous oxide and the sealed nature of the full-face mask. Key clinical lessons include recognition that recreational nitrous oxide use via masks carries acute risk of unconsciousness leading to asphyxia, and chronic risks including vitamin B12 deficiency from regular use. The case highlights gaps in regulation of online nitrous oxide sales and the need for harm reduction education targeting users about dangerous inhalation methods.

Coroner's recommendations
The Victorian Department of Health should review measures implemented or under consideration in South Australia and New South Wales to reduce harms associated with recreational nitrous oxide use, and determine whether any similar measures might be appropriate to introduce in Victoria, taking into account relevant harm reduction principles.
