Health officials in B.C. say more people have died from overdoses so far this year than in the same period of 2016.
It's been a year since the province declared a public-health emergency over the crisis.

But carfentanil, a drug even more powerful than the opioid fentanyl, is believed to be responsible for the recent spike.
