Lola Delmar Leiva-Bernal, 17, was found unconscious by father after he went to check on her.

He tried to revive her and paramedics attempted to resuscitate her in the ambulance on the way to hospital.

However, she was pronounced dead after arriving there.

An inquest into her death, held at Norfolk Coroner's Court, was told Lola - who had been taking a hair and beauty course at City College Norwich - had taken cocaine as well as ketamine.

Her grandmother, Caroline Henderson, told the hearing her granddaughter had had a "turbulent" childhood which had seen her excluded from school.

She had also been in foster placements, which Ms Henderson said had been unsuccessful, and was staying with her father Andrew, at a flat on Springbank, Norwich, at the time of her death.
