The Royal Newfoundland Constabulary is warning of potentially lethal drugs circulating in our community... such as carfentanil with as little as a grain or two capable of killing a person. We hear first from the RNC, and then speak with a harm reduction consultant with the NL Centre on Substance Use program of NL Health Services.
