Whitney Houston's death was caused by accidental drowning, but heart disease and cocaine use were contributing factors, according to coroner's officials, according to CBS reports.
Today’s coroner’s report stated she also had cocaine, marijuana, Xanax, Flexeril, and Benadryl in her system, however, these did not cause her death. As previously reported in leaked reports, there was no sign of trauma to her body which ruled out foul play.
Whitney Houston age 48 died on February 11, 2012. She was found in the bathtub of the Beverly Hilton Hotel on the eve of the Grammy Awards. Prescription drugs were found in her room, but not large numbers.
Coroner's spokesman Craig Harvey says cocaine metabolites were found in Houston's system, and it was listed as a contributing factor in her death. He says the results indicated Houston was a chronic cocaine user.
The coroner said further that the singer also had a heart disease that caused blockages in her arteries. Assistant Chief Coroner Ed Winter said the condition is common in drug users, although he said it wasn't clear whether Houston had a heart attack on the day she died.
"We are saddened to learn of the toxicology results, although we are glad to now have closure," Patricia Houston, the singer's sister-in-law and manager, wrote in a statement to The Associated Press.
She was buried in a New Jersey cemetery next to her father after an emotional four-hour funeral service that was attended by friends, family and superstars such as, , , , , and Roberta Flack.
