Alberta’s Chief Medical Officer of Health and police have issued a warning after the illegal drug carfentanil was proven to have caused two deaths in the province. The opioid is used to tranquilize large animals, and 100 times more toxic than fentanyl.
Even the smallest trace can reportedly be lethal. The Chief Medical Examiner notified Dr. Karen Grimsrud earlier this week that it had been found in the systems of two men in their thirties. One death occurred in the Edmonton area and the other in Calgary.
Until very recently, labs weren’t able to measure carfentanil in human blood.
