CBS News the singer died from accidental drowning but cocaine and heart disease were "contributing factors". Houston had cocaine in her system when she died, the coroner added. Marijuana, Xanax, Flexeril and Benadryl were also found in her system, but did not contribute to the singer's death. Other prescription medications were found on the scene but not in excessive amounts.
SMH...so sad. Whitney apparently fell asleep in the tub after a few cocktails, probably while getting ready for the Clive Davis party that was going on downstairs. According to one of TMZ's inside sources it is "very possible" Whitney had a heart attack that caused her to lose consciousness and drown. The heart attack may have been triggered by hardening of the arteries as a result of cocaine use.
The coroner also suggest that there was no evidence of foul play, even though some of Whitney's closest friends and family members have alleged that there was indeed foul play and that people may even me after the singers 19 year old daughter Bobbi Christina.
Shame on it all!!!!
