LOS ANGELES (CBS) — The Los Angeles County Coroner released the official autopsy report for Whitney Houston Wednesday, detailing additional information about the the singer’s death.
The Coroner ruled Houston’s official cause of death as an accidental drowning in late March, but heart disease and cocaine use were listed as contributors.
Houston, 48, was found submerged in a bathtub filled with extremely hot water (93.5 degrees) in her Beverly Hilton hotel room on Feb. 11, the day before the Grammy Awards.
Cocaine, marijuana, Xanax, muscle relaxers and allergy medications were all found in Houston’s system when she died, according to the final report from the Coroner’s office.
The Coroner previously confirmed that prescription pill bottles were found in her room, but “not in alarming amounts,” People.com reported.
According to the final autopsy report, “a small spoon with a white crystal-like substance in it and a rolled up piece of white paper,” were found in the room by Los Angeles police detectives.
The spoon tested positive for cocaine, according to TMZ. Remnants of a white powdery substance were also found on a small mirror, the report said.
Loose tablets of prescription drugs were found around the room, prescribed by at least four different doctors, the report noted.
No trauma or foul play was suspected.
Houston reportedly ingested cocaine just before she slipped under the water, according to the findings.
The autopsy says alcohol did not play a factor in Houston’s death.
The report stated that Houston was last seen alive between 2:45 and 3 p.m. on Feb. 11 by her personal assistant. The singer had complained of a sore throat and her assistant recommended that she take a bath prior to pre-Grammy party.
When the assistant returned to Houston’s room approximately 40 minutes later, she found the singer face down in the bathtub.
Houston’s assistant and bodyguard called 911 and pulled her body from the bathtub at 3:43 p.m. She was later declared dead at 3:55 p.m. by paramedics, the report said.
Houston had a long history of substance abuse problems. She and then-husband Bobby Brown were arrested in 2000 at a Hawaii airport with marijuana.
The singer was last in rehab in May 2011, but was reportedly seen in the days before her death acting erratically.
Houston was laid to rest on Feb. 19 in New Jersey.
