Silent Killer Revealed: The Drug Outpacing Fentanyl in Deadly Impact—Are You at Risk?

Ever wonder what happens when a drug not only rides the opioid wave but decides to crank the volume way past fentanyl’s notorious level? Well, buckle up, because Europe’s facing a new synthetic opioid menace called nitazenes — reportedly five times stronger than fentanyl and causing havoc with hundreds of deaths across the continent. Now, fentanyl’s been the heavyweight champ in the painkiller ring, known for its ruthless potency and its darker side fueling crises in places like the USA and the UK. But nitazenes? They’re like fentanyl’s scary sibling who showed up to the party uninvited, mixing into everything from heroin and cocaine to party drugs and even vapes, leaving folks vulnerable without a clue. This drug isn’t just a fleeting headline; it’s becoming a public health crisis that experts say rivals the AIDS epidemic’s impact among drug users back in the 80s. Imagine getting your party vape, thinking it’s all good, and instead, you’re dancing with something five times deadlier. If that doesn’t make you pause, what will? Dive into the nitty-gritty of these so-called ‘Frankenstein drugs’ and their global footprint before this shadow pandemic tightens its grip.

An unknown drug considered more potent than fentanyl is wrecking havoc across Europe, according to a new report.

A high-strength medication belonging to the same family as morphine and codeine, fentanyl is used by some healthcare professionals as a form of pain management.

However abuse of the drug has been on the rise in recent years, leading to opioid crises in countries such as the USA and the UK.

Now experts are warning about a similar drug, which is said to be significantly stronger.

According to a report from the Wall Street Journal, a highly-potent synthetic opioid known as nitazenes are thought to be five times stronger than fentanyl and are responsible for hundreds of drug deaths across the continent.

What are nitazenes?

Previously referred to as ‘Frankenstein drugs’, nitazenes were originally developed back in the 1950s, finding their way onto the illegal drugs market in the past few years.

The drug comes in numerous forms and is often mixed with other substances – such as heroin, cocaine and synthetic cannabinoids – with government statistics revealing that 400 deaths were linked to nitazenes from June 2023 to January 2025.

Overdosing on nitazenes can lead to a person exhibiting symptoms such as shallow breathing, bluish lips and skin tone, loss of consciousness and death. Overdoses are typically treating by a medication known as naloxone, which reverses the most fatal effects of the drug.

It isn’t just the UK which is facing the brunt of the crisis either, with nitazenes appearing in street drug mixtures across several US states since 2019 (according to the DEA). Meanwhile kush, a synthetic drug mix often containing nitazenes, is currently ravaging several nations in West Africa.

Prevalence of the drug on UK streets has become so concerning that a spokesperson for Change Grow Live, a UK-based drug charity told WSJ that nitazenes are ‘probably the biggest public health crisis for people who use drugs in the UK since the AIDS crisis in the 1980s’.

The potent drug is also finding its way into party drugs, benzodiazepines and vapes purchased illegally – meaning that people may be taking it without realising.

According to WSJ statistics, two people in London died after allegedly taking oxycodone which had been laced with the drug, while 23-year-old Alex Harpum died from a cardiac arrest after consuming xanax cut with nitazenes back in 2023.

“It’s an international concern. They have been detected on every continent,” Adam Holland, an expert on synthetic opioids at the University of Bristol, added to the outlet.
