A 38-year-old man with a long history of substance use, depression, anxiety and ADHD died from mixed drug toxicity involving metonitazene. He believed he was injecting heroin but had unknowingly obtained metonitazene (a novel synthetic opioid of extreme potency) from an unregulated drug market. The coroner noted this represents an emerging public health threat, with at least 16 nitazene-related deaths in Victoria since 2021, typically occurring when users believe they are consuming other substances. The case highlights that consumers of illicit drugs obtained from unregulated markets cannot verify contents or potency. The coroner recommended Victoria trial a drug checking service to enable harm reduction and inform users of dangerous substances, similar to services operating in the ACT and Queensland. No clinical errors or failures of medical care were identified; rather, the death reflects systemic vulnerabilities in illicit drug markets.

Coroner's recommendations
Department of Health trial a drug checking service in Victoria to gather evidence, experience and insights into how drug checking might reduce risks (including preventable deaths) associated with use of drugs obtained from unregulated drug markets
Drug checking services should be designed to be available to all Victorians, not just metropolitan Melbourne, with consideration of different service delivery models for regional areas
Drug checking trial should provide insights into delivering drug checking as a general harm reduction service rather than an event-specific service limited to music festivals or designated events
