A distraught mother has taken to Facebook to voice her fears about the prescription drug Fentanyl after her son accidentally overdosed.
Sherri Kent, mother of 22-year-old Michael from Calgary in Canada, shared a distressing photo of her son hours before his death to warn others of the deadly drug which is sweeping Canada.
The photo shows a sobbing Kent holding on to her unconscious son in his hospital bed following an overdose of the opioid, which is said to be 50 to 100 times stronger than morphine.
