Kevin King guides a man through the fentanyl testing process in a blue tent in the alley behind St. Paul's Hospital.
After a brief wait, King, a self-described rocker with dyed blond hair and multiple chains dangling near his belt, shows the man a single line on the test strip, revealing that the tiny sample of drugs tested contains fentanyl.
The man says he's been using the same drugs for months and hasn't overdosed, but leaves the facility discouraged, without injecting.
