Toxicology test results might not be revealed for six to eight weeks.
Whitney Houston's family was told by Los Angles County Coroner officials that the 48-year-old singer did not die from a bathtub drowning, but rather from what appears to be a combination of Xanax and other prescription drugs mixed with alcohol, according to TMZ.
Citing family sources, the website reported there was not enough water in Houston's lungs to lead to the conclusion that she drowned.
The prescription drugs found in her Beverly Hills hotel room following her death on Saturday afternoon included ibuprofen (painkiller), Xanax (anti-depressant), Midol (for menstrual cramps), and amoxicillin (antibiotic), TMZ reported.
Los Angeles Deputy Coroner Ed Winter said at a press conference that toxicology tests could take six to eight weeks to process, according to Fox News.
Houston's body was removed from the hotel early Sunday morning, hours after the Grammy awards party she was there to attend had taken place four floors below her room.
Houston was one of the world’s best-selling artists from the mid-1980s to the late 1990s. She awed millions with soaring, but disciplined vocals rooted in gospel and polished for the masses, a bridge between the earthy passion of her godmother, Aretha Franklin, and the bouncy pop of her cousin, Dionne Warwick.
Her success carried her beyond music to movies, where she became a rare black actress with box office appeal, starring in such hits as “The Bodyguard” and “Waiting to Exhale."
The past decade had been marred by substance abuse and erratic behavior.
