New evidence shows a growing threat from a class of synthetic opioids known as nitazenes — which may be up to 500 times more potent than heroin — appearing in Australia in fatal overdose clusters. In June 2024, four individuals died in Melbourne after inhaling what they believed to be cocaine, later identified as the nitazene variant protonitazene. These drugs, originally developed in the 1950s but never approved, are increasingly found adulterating other illicit substances (such as “cocaine,” pills or vapes). At least 30 confirmed nitazene-related overdoses are recorded in Australia since 2021 — the actual number is likely higher.

 

 

 

Experts warn that because of their extreme potency, even microscopic amounts can rapidly induce respiratory depression and death — often before help arrives. Health authorities mention that responses such as expanded distribution of naloxone, drug-checking services, and broader education are urgently needed — yet in some states, political or regulatory resistance hampers progress. 

 

Key Takeaways:

 

Extreme potency & hidden risk: Nitazenes can be hundreds of times stronger than heroin and may be unknowingly present in substances sold as cocaine, pills or vapes.

 

Rapid fatal impact: Even tiny doses of nitazenes can cause sudden overdose; typical opioid reversal strategies may require higher or multiple naloxone doses.

 

Urgent harm-reduction need: Authorities recommend naloxone availability, drug-checking services and awareness campaigns — but action is inconsistent across regions.

AKA fentanyl

Nitazenes and fentanyl are chemically different but pharmacologically similar — both are powerful synthetic opioids that can cause fatal overdoses even in microgram amounts.

 

This is frightening!

Well as long as it's fatal.

Am keen, love me some opioids!

If people didn't take illegal drugs there wouldn't be a drug problem.  Imho, it's a Darwin Award for those stupid enough to indulge in hard narcotics.  I have little sympathy.

Some really nasty stuff.

Don’t you think eradicating off the streets and keeping it from entering the country would reduce the problem, or not?

discounting the counterfeit  version  some brilliant life changing medication is not "nasty stuff" for those suffering from chronic intense pain.   They should not be deprived of this due to the idiots who abuse it and  occasionally suffer the consequences.

Government have been attempting to "eradicate drugs from off of the streets" since before I was born, and they are attempting to "eradicate drugs from off of the streets" today, generally by arresting and throwing users into prison.  The so-call "war on drugs" is patently unwinnable.  No government will ever stop the trafficking because those who want drugs create the conditions for the production and sale of drugs. If there were no users, there'd be no markets.  But there are millions of users, so the are hundreds of billions of dollars in revenues to be made. Governments will never stop it - ever.  So, imho, you allow those who wish to kill themselves with drugs to do so.  Darwinism solves part of the problem. 

 You're callous!!!
 Yep.

You seem pretty far behind and myopically digressed on understanding basic civility and why governments control drug use. Besides for the fact that it’s destructive to lives and families, it also has an economic impact that would include a whole slew of factors like medical, damage property, loss of work force due to death and dysfunctional drug users, homelessness due to drug addiction and on and on and on. It’s people like you that help bring down society having no foresight and only irresponsible verbiage of apathy, in other words, your only solution is dysfunction.
