The official cause of death for Whitney Houston is drowning and "effects of atherosclerotic heart disease and cocaine use," according to a report released Thursday by the L.A. County Department of the Coroner. The report indicates that Houston died when she was submerged in a bathtub filled with water, and also indicates that she had ingested cocaine. Her death has been ruled as accidental. Cocaine was said to have contributed to her death, but not the prescription drugs and marijuana also found in her system. The press release from the report concluded, "No trauma or foul play is suspected." The final coroner's report is expected to be released within two weeks. Whitney Houston was found under water in her bathtub on Feb. 11 in her Beverly Hilton Hotel suite one day before the Grammy Awards. She was buried in Westfield, N.J., on Feb. 19.
