LOS ANGELES (AP) -- Detectives found white powdery substances and a spoon with white residue in the hotel room where Whitney Houston died, according to the final autopsy report released Wednesday.
The report also shows that Houston had cocaine throughout her system.
The report details the singer's final day, with the singer complaining of a sore throat and an assistant suggesting she take a bath before preparing for a pre-Grammy party.
The Grammy-winning singer died Feb. 11 after drowning in a bathtub at the Beverly Hilton Hotel. Her death has been ruled as accidental and coroner's officials cited heart disease and cocaine use as contributing factors.
The singer had battled addiction for years, but friends and family have said she appeared committed to making a comeback in the months before her death.
"The biggest devil is me. I'm either my best friend or my worst enemy," Houston told ABC's Diane Sawyer in an infamous 2002 television interview with then-husband Bobby Brown by her side.
