Deadly Animal Drug Surges in UK Street Ketamine

An alarming new threat has emerged in the UK's illicit drug market with the detection of medetomidine, a powerful animal tranquilizer, in ketamine samples. This substance, around 200 times more potent than xylazine, has contributed to a surge in drug overdoses in the United States, turning cities into "zombielands." UK universities, including Manchester and Durham, have issued urgent warnings, highlighting that medetomidine can cause prolonged and potentially fatal sedation when mixed with ketamine.

Medetomidine, approved solely for veterinary use, is increasingly being blended into street drugs, creating deadly cocktails. While it may offer a perceived boost in euphoric effects, its extreme potency and long-lasting impact pose significant risks. Health officials note that it does not respond to standard opioid reversal medications like naloxone, though naloxone is advised due to its frequent co-use with opioids. Atipamezole is identified as a potential reversal agent, but it has not been approved for human use.

The emergence of medetomidine in ketamine, a drug already linked to numerous student deaths and rising usage rates, signals a worrying escalation of drug-related harms. With ketamine use among young adults in England and Wales at 4.8%, and government figures showing an 85% increase in usage over the past year, the contamination with medetomidine presents a critical public health challenge.
