Whitney Houston's official cause of death: accidental drowning due to cocaine use and heart disease, Los Angeles County coroner's spokesman said to press
Pop star was found submerged, face down in a bathtub of her Beverly Hills hotel room last February 12, 2012 the day before the Grammy Awards.
According to the autopsy, the cocaine use and her atherosclerotic heart disease contributed to her accidental drowning, said Los Angeles County coroner's spokesman Craig Harvey.
Also seen in her toxicology test are marijuana, anti-anxiety medication, a muscle relaxant, and anti-histamine in her blood but these didn't contribute to the 48-year old singer's sudden passing. No signs of foul play either.
A final report will be release to the public in two weeks.
"We are saddened to learn of the toxicology results, although we are glad to now have closure," said manager and sister-in-law Patricia Houston.
The multi-awarded singer battled with drug abuse but has already recovered according to a recent interview with TV host, Oprah Winfrey.
She has undergone rehab in May 2011 but was spotted drinking heavily and behaving erratically days before her death.
Whitney Houston rose to fame in the 1980's and has given us timeless hits like "I Will Always Love You" and "Saving All My Love For You" just to name a few.
