Fraser Health issued an overdose alert for drugs that are being sold in the region.

"Multiple samples in different colours and textures, containing several Fentanyl Analogs (including Carfentanil), Benzodiazepines, Veterinary Tranquilizers (Tranq), and Nitazenes (a group of potent opioids), were tested throughout the Fraser Health region," reads the alert.

"Combining multiple depressants can lead to complex overdoses. Naloxone will reverse the effects of opioids if present, but it does not reverse effects of benzodiazepines and tranquilizers. Individuals may not regain consciousness and require longer monitoring. Monitor breathing, before administering more naloxone.," .
