The Los Angeles County coroner’s office has determined that Whitney Houston’s official cause of death is accidental “drowning and effects of atherosclerotic heart disease and cocaine use.”
The iconic singer was found in the bathtub of her Beverly Hilton Hotel room on Feb. 11, hours before a pre-Grammy party. She was 48.
The toxicology report added that “Cocaine and metabolites were identified and were contributory to the death. Marijuana, Alprazolam (Xanax), Cyclobenzaprine (Flexeril) and Diphenhydramine (Benadryl) were identified but did not contribute to the death.”
Whitney’s cousin Dionne Warwick said earlier this month she suspected her cousin died of a “heart attack.”
“We are saddened to learn of the toxicology results, although we are glad to now have closure,” Patricia Houston, Whitney’s sister-in-law and former manager, said in a statement.
