Hamilton Police have offered an explanation for the delay in releasing information about liquid Fentanyl found during a drug raid in May.
When the news broke last week, police said they had only recently been informed that it was liquid Fentanyl.
But Health Canada says it contacted police in July, both by phone and by mail, confirming the substance sent for testing was the potent liquid Fentanyl.
The Spec is reporting that an email from Detective Sergeant Frank Mossuto says the delay was to allow police to do more research on the drug.
Liquid Fentanyl is of such concern to police that special precautions are taken to avoid any direct contact with it.
Health Canada says as a little as 2 milligrams or the equivalent of 32 grains of salt can kill.
