Canberra Teen’s Drowning Death Sparks Call for Nitrous Oxide Review
A coroner has identified the utilize of nitrous oxide, commonly known as “nangs,” as a significant contributing factor in the 2023 drowning death of an 18-year-traditional driver in Canberra. The ruling has prompted urgent recommendations for the ACT government to review the availability of the gas and implement targeted educational programs to warn the public about its risks.
The July 2023 Incident at Isabella Pond
The tragedy occurred on July 22, 2023, in Greenway, located in the south of Canberra. An 18-year-old P-plater was driving a Holden Commodore along Drakeford Drive when the vehicle veered off the road, crossed a median strip, and entered Isabella Pond. The car quickly became submerged, and the driver drowned.
Police divers were deployed to the scene, where they eventually recovered the teenager’s body from the submerged vehicle.
Nitrous Oxide Impairment and Evidence
Coroner Ken Archer determined that the driver was significantly impaired by nitrous oxide shortly before the crash. While the teenager’s name has been suppressed, the evidence gathered during the investigation pointed to the use of “nangs”—nitrous oxide typically sold in slight steel cartridges or large high-pressure canisters.
Key evidence cited in the coroner’s report includes:
- Witness Testimony: Observers reported seeing the teenager inhaling from a balloon or a round-shaped object while navigating a roundabout moments before the vehicle left the road.
- Physical Evidence: Investigators found several nitrous oxide cartridges inside the car.
According to Coroner Ken Archer, this is the first recorded fatal motor vehicle accident in the ACT where nitrous oxide impairment was found to be a significant contributing factor.
The Challenge of Post-Mortem Detection
The case highlighted a critical gap in forensic capabilities within the territory. Because the ACT lacks a specific test to detect nitrous oxide during an autopsy, pathologists were unable to confirm the presence or the exact level of the gas in the teenager’s system after death.
Mr. Archer noted that these detection difficulties mean there is often little direct evidence of impairment in fatal road accident cases involving nitrous oxide, which raises significant public safety concerns.
Coroner’s Recommendations for the ACT
In light of these findings, the coroner has called for systemic changes to prevent similar tragedies. The primary recommendations include:
- Regulatory Review: A formal review of the availability and regulation of nitrous oxide within the ACT.
- Public Education: The development of targeted educational materials that clearly address the dangers and risks associated with nitrous oxide use.
Key Takeaways
- Victim: An 18-year-old P-plater.
- Cause of Death: Drowning after crashing a Holden Commodore into Isabella Pond.
- Contributing Factor: Significant impairment caused by nitrous oxide (“nangs”).
- Legal Precedent: First fatal ACT road accident linked to nitrous oxide impairment.
- Forensic Gap: No current autopsy test in the ACT to detect nitrous oxide.
Frequently Asked Questions
What are “nangs”?
“Nangs” is a colloquial term for nitrous oxide, a gas typically sold in small steel cartridges or larger high-pressure canisters that is inhaled for recreational purposes.

Why was it difficult to prove the driver used nitrous oxide?
Detection is challenging because there is currently no test available in the ACT to identify nitrous oxide during a post-mortem autopsy.
Where did the accident happen?
The accident occurred in Greenway, Canberra, when a car left Drakeford Drive and entered Isabella Pond.
