Vancouver police are issuing a public warning to local drug users about a potentially fatal heroin that is in circulation. Two women — one 26 years old and the other 19 years old — have died from possible heroin overdoses, said Const. Lindsey Houghton.

Houghton said that in a third case, a man had injected heroin, but it was mixed with an unknown substance and caused very serious side-effects

The Vancouver Police are warning drug users to be extremely cautious and advised that they use the services of the supervised injection site Insite on East Hastings Street, he said.

Houghton said police have advised a number of local agencies, including the Insite clinic, Vancouver Coastal Health and the B.C. Ambulance Service that the powerful and possibly toxic heroin is on the streets.
