Ever since Amy Winehouse was found dead in her London flat on July 23 at the age of 27, mourning fans and friends have wondered about the exact cause of death for the troubled singer, who famously battled drug addiction. It turned out that drugs weren't the cause — it was alcohol, the BBC reports.

British coroner Suzanne Greenway announced Wednesday that Winehouse suffered a "death by misadventure" and that high blood alcohol levels — at five times the level of the drunk driving limit — were the main cause. "'She had consumed sufficient alcohol at 416mg per decilitre (of blood) and the unintended consequence of such potentially fatal levels was her sudden expected death," Greenway said.

Winehouse's family issued a statement after the inquest, acknowledging that the singer did have an ongoing battle with alcohol. "We understand there was alcohol in her system when she passed away — it is likely a build-up of alcohol in her system over a number of days," the statement read. "The court heard that Amy was battling hard to conquer her problems with alcohol and it is a source of great pain to us that she could not win in time."
