In a press release, Sgt. Randy Fincham advised drug users to use the services of Vancouver's supervised injection site Insite, which has medical staff available to help.
The only legal supervised injection site in North America, Insite has seen more than two million visitors since it opened in 2003 and not a single death.
Police urge anyone seeing someone appearing to be in medical distress to call 911. Drug users who don’t feel well after injecting are urged to seek medical attention or help immediately.
