Cause of death
Complications of malnutrition in the setting of presumed nitrous oxide use
AI-generated summary
A 20-year-old university student living alone in Melbourne died between 28 July and 7 August 2020 from complications of malnutrition in the setting of presumed nitrous oxide use. Thousands of nitrous oxide canisters were found at her apartment. She had a critically low BMI (11 kg/m²) and evidence of prolonged malnutrition including pressure ulcers and gastric stress erosions. The pathologist noted that sustained nitrous oxide intoxication likely led to poor self-care including reduced eating and drinking. While nitrous oxide is legal and readily available online, the coroner emphasised the increasing prevalence of recreational use (particularly among young people) and recommended enhanced retailer education and harm reduction resources for users to address preventable deaths in this emerging public health issue.

Coroner's recommendations
- The Department of Health should consider developing a kit similar to the Responsible Sale of Solvents: A Retailer's Kit specifically for retailers of cream whipper bulbs and other nitrous oxide sources to alert them to their obligation to have reasonable belief that nitrous oxide will not be inhaled
- The Department of Health should consider developing an education resource for recreational users of nitrous oxide outlining the dangers of the drug and specific elevated risks associated with practices such as using tubes and masks
- The Department of Health should distribute the education resource to all Australian online retailers of cream whipping nitrous oxide bulbs and request incorporation into their websites in visible manner for purchasers
- The Victorian Department of Health should have regard to South Australia's approach (which introduced age restrictions, time-of-sale restrictions, visibility controls, and notice requirements) in considering whether legislative changes are needed in Victoria
