The Northwestern Health Unit is warning the public over the potential of overdoses stemming from the region's supply of crack cocaine.

In a release issued only to social media the health body says fentanyl was detected by a test strip in a sample of the unregulated supply.

It's warning users not to be alone while using, to carry Naloxone and know how to use it.

Overdoses manifest with a number of symptoms including:

  • loss of consciousness
  • laboured breathing or no breathing at all
  • dizziness
  • sudden unresponsiveness
  • vomiting
  • diarrhea
  • choking gurgling or snoring sounds
  • blue or purple fingertips
  • unresponsiveness to loud noises or shaking

If you witness someone who is overdosing Naloxone administered right away can counter these symptoms.
