Coroner Report: Whitney Houston's Death 'Accidental Drowning'

The Los Angeles County Coroner's Office has determined that Whitney Houston died of accidental "drowning and effects of atherosclerotic heart disease and cocaine use," USA Today reports.  The toxicology report also found marijuana and ingredients found in Xanax, Flexeril and Benadryl but those drugs didn't contribute to her death.  Houston was found dead in her Beverly Hilton Hotel room on February 11, just hours before she was to attend a pre-Grammy Awards party hosted by her mentor Clive Davis.  The 48 year-old pop icon was laid to rest in New Jersey on February 18, following funeral services at her family church in Newark, NJ.  Houston's only daughter, Bobbi Kristina, was named the sole heir to her estate.  The final coroner's report is expected to be released within the next two weeks.
