A synthetic opioid 25 times more powerful than fentanyl has made its way to the Quebec City region, where public health officials reported Feb. 10 they have detected the dangerous compound in pale green tablets that mimic the appearance of other prescription opioids.
The Quebec City regional public health authority warned the compound, protonitazepyne, presents a high risk of overdose, which may require several doses of the life-saving medication naloxone.
