There were 2,356 drug-induced deaths in Australia in 2022, according to the Penington Institute’s annual drug overdose report.
Of these overdose deaths, 80 per cent were unintentional and 73 per cent involved two or more drugs.
Penington Institute CEO John Ryan told ABC News that most overdose fatalities were polysubstance deaths.
“Drugs have a multiplier effect in combination,” he said.
“So, if you have opioids, plus some alcohol, that actually increases your risk of overdose – and especially if you add in benzodiazepines.”
While deaths from some prescription opioids have decreased, overall opioid deaths, particularly from heroin, have continued to rise, the Penington report found.
“What we are seeing with opioids has been consistent now for the last 20 years, which is that they are the main driver of overdose deaths, typically in combination with other drugs,” Ryan said.
Ryan said synthetic opioids such as fentanyl, and now nitazenes, were increasingly showing up in overdose data.
The report found:
- the number of unintentional drug-induced deaths has grown by 108 per cent since 2002 even though the population has only increased by 33 per cent
- the road toll has dropped 27 per cent since 2002, but unintentional drug-induced deaths have more than doubled
- Indigenous Australians are almost four times more likely to die of unintentional overdose compared with non-Indigenous Australians
- unintentional deaths involving heroin increased by more than 400 per cent between 2002 and 2022.
