Via CBC News British Columbia: Deadly opioid carfentanil found in street drug in Nelson, B.C. Excerpt:
Police are warning the public that carfentanil, an "extremely dangerous" synthetic opioid used to tranquilize elephants, has been found in street drugs seized in Nelson, B.C., in the province's West Kootenay.
The Nelson Police Department seized suspected counterfeit oxycodone tablets during a recent arrest, and sent them to Health Canada for testing, which confirmed the presence of the drug, said Detective Constable David Laing.
"Carfentanil is extremely dangerous," said Laing. "Unfortunately this stuff is so potent it could be a lot more challenging than we have had in the past."
