Los Angeles (CNN) -- Whitney Houston died from an accidental drowning in a hotel bathtub, but the "effects of atherosclerotic heart disease and cocaine use" were contributing factors in her death, the Los Angeles County coroner said in an initial autopsy report released Thursday. Houston, 48, was "found submerged in bathtub filled with water" and "no trauma or foul play is suspected," the coroner said in a one-page release. Her cocaine use appeared to have occurred "in the time period just immediately prior to her collapse in the bathtub at the hotel," Chief Coroner Craig Harvey told reporters. The 60% narrowing of her arteries "suggest a cardiac event complicated by the cocaine use" led to Houston's slipping underwater, Harvey said.

The toxicology tests found other drugs in her body, including marijuana, the anti-anxiety drug Xanax, the muscle relaxant Flexeril and the allergy medicine
