The Los Angeles County Coroner's office said Thursday that singer Whitney Houston died of an accidental death in her hotel bathtub and a toxicology report added that heart disease and cocaine use contributed to her death on February 11. 

The official report stated Houston died due to "drowning and effects of atherosclerotic heart disease and cocaine use."

The section of the report entitled "How injury occurred" stated Houston was "found submerged in bathtub filled with water; cocaine intake."

The report said "no trauma or foul play is suspected."

"Cocaine and metabolites were identified and were contributory to the death," the report states. "Marijuana, alprazolam (Xanax), cyclobenzaprine (Flexeril) and diphenhydramine (Benadryl) were identified but did not contribute to the death."

Assistant Chief Coroner Craig Harvey told reporters Houston's cocaine use appeared to have taken place "in the time period just immediately prior to her collapse in the bathtub at the hotel," according to CNN.

Coroner assistant chief Ed Winter told People Magazine there are two likely scenarios that could have led to Houston's death.

"She could've passed out first due to the intoxication from the cocaine, or she could've had a heart attack and then drowned," Winter said. "It's probably one of those two scenarios."

Houston's family issued a statement after the results were released.

 "We are saddened to learn of the toxicology results, although we are glad to now have closure," said Patricia Houston, the singer's manager and sister in law in a released statement.
