Whitney Houston Cause of Death: Drowning

The LA county coroner has ruled that the official cause of death for Whitney Houston is accidental drowning, reports AP. But the report also cited cocaine and heart disease as contributing factors, and noted that she had the drug in her system at the time of her death, along with marijuana, Xanax, a muscle relaxant, and Benadryl. One insider lays out a possible scenario for TMZ: She had a heart attack in the hotel bathtub, which caused her to lose consciousness and go under. The heart attack itself may have been triggered by hardening of the arteries, caused by regular cocaine use.

“We are saddened to learn of the toxicology results, although we are glad to now have closure," said the Houston family in a statement. (More Whitney Houston stories.)
