A woman celebrating her 50th birthday with friends collapsed and died after snorting cocaine in the Cotswolds, an inquest heard.
Michaela Hunter was with three friends in the Gloucestershire market town of Wotton-Under-Edge, when she snorted two lines of the class A drug during the evening.
Gloucestershire Coroner's Court was told that Ms Hunter had also drunk a small amount of vodka on July 5 and later went to bed.
She became unresponsive so her friends called paramedics who carried out CPR but they were unable to revive her.
She died in the early hours of July 6.
A post mortem report said Ms Hunter, from Hartley Wintney in Hampshire, died from a sudden cardiac death brought on by sustained cocaine use.
Coroner Roland Wooderson said Ms Hunter had a substantial dosage of the drug in her body, amounting to acute cocaine toxicity, which had also contributed to her suffering from ischemic heart disease.
Ms Hunter's family asked the assistant coroner Roland Wooderson if she would have survived if an ambulance had been called earlier.
Mr Wooderson replied: "I am unable to answer that particular question, but it would not change the outcome over my decision into her death."
The coroner recorded that Ms Hunter suffered from a drug-related death.
