Houston drowned in bath: Coroner

Whitney Houston was a chronic cocaine user who had the drug in her system when she drowned in a hotel bathtub, coroner's officials said on Thursday after releasing autopsy findings that also noted heart disease contributed to her death.

The disclosure ended weeks of speculation about what killed the Grammy-winning singer on Feb 11, on the eve of the Grammy Awards.

Houston was found submerged in the bathtub of her room at the Beverly Hilton Hotel, and her death was ruled accidental. Several bottles of prescription medications were found in her hotel room, but coroner's officials said there weren't excessive quantities.
