Singer Amy Winehouse was more than three times times over the drink drive limit when she died, the inquest into her death has heard.
The inquest, at St Pancras Coroner's Court in London, heard Winehouse had 416mg of alcohol per 100ml of blood.
The driving limit in the UK is 80mg.
The hearing was told the Back To Black star had not had a drink in July until Friday July 22nd.
She was found in bed in her Camden home in north London the next day. Police recovered three bottles of vodka, two large and one small.
A post-mortem examination found Winehouse's vital organs in good health and with no traces of illegal drugs.
But she had huge amounts of alcohol in her system which could have stopped her
breathing and sent her into a coma.
The inquest heard her security guard looked in on her at 10am the day she died but left her for five hours before calling the emergency services.
The live-in guard, Andrew Morris, said he thought she was asleep when he initially checked on her but at 3pm he checked again and she had not moved.
An initial postmortem examination proved inconclusive and no cause of death was given when the inquest was opened and adjourned in August.
Her father, Mitch Winehouse, told mourners at her funeral his daughter had been the happiest she had been in a long time in the weeks before her death.
He said Winehouse had "conquered" her drug addiction and was "trying hard to deal with her drinking".
A verdict of death by misadventure was recorded.
