The toxicology report is in. The Los Angeles County coroner's office has determined that Whitney Houston's official cause of death is "drowning and effects of atherosclerotic heart disease and cocaine use."
The famous singer was found in the bathtub of her hotel room on February 11, just hours before a pre-Grammy party. She was 48 years old.
The coroner's office also reported that the manner of death was an "accident."
However, the toxicology report adds 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."
An autopsy was conducted the day after she died. Capt. John Kades of the Los Angeles County coroner's office said at the time there were no indications of foul play and no obvious signs of trauma on Houston's body. Prescription pill bottles were found in her room, but the number of pills were "not in alarming amounts," said officials.
