Police said the shipments of the fentanyl precursor were discovered in four cardboard barrels by Canadian border guards at the Edmonton International Airport. They had been shipped from somewhere in China.
The announcement comes in the midst of a public health crisis around fentanyl in Canada, with hundreds of reported overdoses throughout the country in the last few years
W-18 is supposed to be a powerful opiate responsible for a Canadian man's death — but it might not be powerful, an opiate, or responsible for his death at all.
Testing confirmed the Calgary man also had heroin and 3-methyl fentanyl, which is 10 to 15 times stronger than heroin, in his system. It's unclear exactly which drug was the direct cause of his death.
Canadian police confiscated samples of the drug recently and believe it is being imported from China by organized crime.
