Whitney Houston's Cause Of Death Revealed

The Los Angeles County Coroner's Office has released Whitney Houston's official cause of death.

An autopsy and toxicology results indicate that the six-time Grammy honoree died as a result of an accidental drowning to which cocaine use and heart disease contributed, reports E! Online. Houston, 48, was found unconscious the evening of Feb. 11 in her Beverly Hills Hilton hotel room's bathtub by a personal security guard. Paramedics were called and tried resuscitation for roughly 20 minutes before declaring her dead.

Cocaine wasn't the only foreign substance the singer was found to have ingested. The coroner's report adds that traces of Benadryl, Xanax, Flexeril and marijuana were found in her system, too. The report indicates that those substances did not contribute to her death. Neither foul play nor trauma apparently factored into her death, either.

As noted on the website, E! News first reported Feb. 28 that Houston's passing had been apparently accidental.

It's been widely speculated since her death that drugs and/or alcohol played some role or another. Houston had re-entered drug and alcohol rehab as recently as the previous May, as acknowledged by her publicist. Cocaine use and heavy drinking contributed in the early 2000s to Houston's career collapse, in which she became notorious for showing up late or not at all to appearances and canceling performances as her once-powerful voice grew weak and raspy.

A final coroner's report should be made public within roughly the next two weeks.
