Winnipeg police have confirmed they seized the deadly street drug carfentanil from a city hotel room, where they found blotter tabs that lab tests confirmed contain the powerful opioid. Winnipeg police say these tabs, seized in a raid at a hotel room earlier in September, contain the deadly drug carfentanil. (Winnipeg Police Service)The presence of carfentanil, a synthetic opioid that is 100 times stronger than the highly addictive fentanyl, is frightening, police and health officials said. Joss Reimer, the Winnipeg Regional Health Authority's medical officer of health, adding the alert for first responders has been heightened. It is also mixed with other street drugs such as cocaine, said health officials, who added there's no way to safely determine a non-lethal amount of carfentanil.
