Several recent deaths are being investigated in the Huntsville and Muskoka Lakes areas that may be associated with an unusually potent strain of purple heroin, OPP say.
Purple, also known as “Purp,” is heroin that’s been mixed with fentanyl or carfentanil, police add.
According to the Simcoe Muskoka District Health Unit, fentanyl and carfentanil are powerful synthetic opioids. Fentanyl is 100 times stronger than morphine and 40 times more than heroin, while carfentanil is 100 times more potent than fentanyl and 10,000 times more than morphine.
Carfentanil is also intended for veterinary use to sedate large animals.
