Australian authorities warn of nitazenes, a synthetic opioid linked to rising overdose risks and seizures of 64 imports in the last year

Authorities have issued a stark warning over the increasing threat posed by nitazenes, a synthetic opioid reportedly “10 times more potent than fentanyl.” The Australian Federal Police (AFP) has raised alarms following the interception of over 60 imports of this dangerous drug over the past two years.

Primarily imported through international mail streams from Hong Kong, the UK, and Canada, nitazenes are often disguised as other substances like cocaine, MDMA, GHB, and counterfeit pharmaceuticals. The Australian Border Force (ABF) detected 64 cases between January 2023 and September 2024, highlighting the widespread nature of the problem.

Nitazenes are especially concerning due to their extreme potency. Even small quantities can result in fatal overdoses, with symptoms including loss of consciousness, erratic breathing, and death. AFP Commander Paula Hudson compared the risks of nitazenes to “playing Russian roulette,” with the smallest dose capable of triggering a fatal reaction.

In addition to being deadly to users, nitazenes pose a risk to law enforcement and emergency responders who may unknowingly come into contact with the drug. AFP forensic teams have already seized significant amounts, including a 4-kilo haul found during a raid in Melbourne, while other arrests have been made in connection to the importation of metonitazene.

The AFP has vowed to continue collaborating with international law enforcement agencies to combat the trafficking of these potent opioids, with a particular focus on dismantling criminal networks involved in their importation.
