One of the most dangerous of the opiates has hit the streets of Thunder Bay.
Emily Groot says lab reports confirm the presence of the drug carfentanil.
She says it's been detected with increasing frequency in Canada, but it's the first time it's been found here.
Groot notes carfentanil is 10,000 times more toxic than morphine.
She indicates it is sometimes used to enhance the strength of regular street drugs which is why users should be very careful.
