DEA warns of "super labs" in Canada producing fentanyl, a drug tied to many US overdose deaths.

The DEA has identified "super laboratories" in Canada producing fentanyl, a potent opioid linked to numerous overdose deaths in the US. Though current fentanyl imports from Canada are lower than from Mexico, the DEA warns these labs could expand if Mexican production is disrupted. The DEA also noted the RCMP dismantled a drug lab in British Columbia last year. This report marks a new concern in the ongoing drug crisis.
