A new warning has been issued across the UK after medetomidine, an animal tranquiliser hundreds of times stronger than xylazine, was found mixed into ketamine. Universities in Manchester and Durham have already confirmed contaminated samples.
This matters because people using ketamine have no way of knowing if it contains medetomidine. The risks are extreme sedation, loss of consciousness, slowed breathing, and heightened vulnerability to harm. Medetomidine doesn’t respond to Naloxone, and its effects can last far longer than ketamine alone.
If you or someone you’re with becomes unwell, unconscious, or struggles to breathe, call 999 immediately and put them in the recovery position. Don’t wait to see if things improve.
Harbour is here for anyone affected by drug use. If you’re worried about your own use or someone else’s, reach out, drop in, or speak with one of our team. Staying informed keeps people safer.
