Fraser Health issued an overdose alert for drugs that are being sold in Surrey.
"Beige/yellow chunks sold as Fentanyl contain high concentrations of Medetomidine, a veterinary sedative similar to Xylazine but with a higher potency and longer duration of action," reads the release.
“If someone overdoses: call 9-1-1 and stay with them. Give one breath every five seconds. Give naloxone. Please look out for each other,” it continued.
The warning also listed tips for safe drug use, as well as links to local harm reduction services and how to get your drugs checked.
The alert was posted online and sent via text using the Toxic Drug and Health Alerts System, which is managed by BC Centre for Disease Control.
