A Londonderry mother whose daughter died in February has warned young people about the dangers of abusing the prescription drug, pregabalin.

Jasmin Duddy was just 21 years old when she was found unresponsive at a house in Galliagh in the city.

Her mother Pauline Duddy said a post-mortem examination later revealed Jasmin had pregabalin in her system.

Her mother's warning comes after three drug-related deaths in the north-west earlier this month.

The police in Derry have also said they are attempting to locate a batch of extra-strength pregabalin tablets.

The drug is normally used to treat epilepsy and anxiety, according to the NHS.

Ms Duddy has called for tougher sentences on drug dealers and said more families will be left heartbroken unless more is done to tackle drug addiction.
