The L.A. county coroner has ruled the death of legendary singer and actress Whitney Houston as an accidental drowning.

The official cause of death report, released this evening, cites cocaine use and heart disease as contributing factors in Houston's early demise.

The toxicology report found traces of cocaine metabolites in the singer's body, leading doctors to conclude Houston was a chronic user of the drug. Evidence of the drugs Xanax, Flexeril, marijuana and Benadryl were also found in Houston's body but the report states those drugs did not contribute to her death.
