Singer Amy Winehouse‘s death on July 23rd was the result of alcohol toxicity, an inquest ruled Wednesday.

CNN reports that, according to a pathologist, Winehouse’s blood-alcohol levels measured at more than five times the legal limit for driving. Tests revealed that Winehouse’s blood-alcohol level was 416 milligrams per 100 milliliters of blood. The level considered lethal is 350 milligrams per 100 milliliters of blood, and the legal limit to drive in Britain is 80 milligrams of alcohol.

Testimony at her inquest showed no traces of illegal drugs in her system.

Winehouse was 27.
