Mother warns of drug dangers after death of teenage son

The grieving mother of a teenager who died after taking a lethal dose of a powerful prescription drug has warned others not to risk their lives looking for an illegal high.

Robert Fraser, 18, from Deal in Kent, died after taking fentanyl - a synthetic opiate that is a hundred times more potent than heroin.

Michelle Fraser said he was a "bubbly" teenager with "his whole life ahead of him" who did not understand the risks he was taking.
