The highly toxic opioid carfentanil has appeared in Toronto, with police announcing Wednesday they have seized heroin laced with the drug considered to be 10,000 times more potent than morphine.
Carfentanil was only publicly confirmed to be in Ontario on Tuesday. Waterloo Regional Police announced that an analysis of 85 counterfeit pills seized there showed they contained amounts of carfentanil rather than OxyContin.
No amount of the drug is safe for human consumption, public health officials say. It’s designed to sedate large animals — like moose and elephants — and even one microgram will cause a reaction in humans.
A grain of salt
To put that in perspective, a grain of salt weighs at least 100 times that amount — and that’s why police and Toronto Public Health officials say that just one grain can be fatal.
Carfentanil has not yet been tied to any deaths…
