After weeks of speculation, it appears that drug use was indeed the cause of Houston's death. The pop icon had cocaine in her system when she drowned in a hotel bathtub, according to the official report released by the Los Angeles Coroner.  Sources say that someone must have gotten rid of all evidence of cocaine prior to the authorities arriving at the scene.

She sunk into the bathwater after suffering a massive heart attack caused in part by her prolonged drug abuse.
Ed Winter, spokesman for the coroner’s office, said the official cause of death was accidental drowning.
He added that heart disease and the star’s cocaine use were contributing factors to her collapse.
The Chief Coroner Craig Harvey stated during a press conference that the results suggest 'chronic usage' of cocaine by Ms. Houston.
He said there was 'an acute dose' of cocaine in Houston's system when she died.
Harvey added that the results indicate the star ingested cocaine 'not probably too much before she collapsed'.
Coroner’s officials said the results suggest Ms. Houston was a chronic cocaine user.
Traces of marijuana and the prescription anti-anxiety drug Xanax were found along with Flexiril and over-the-counter Benadryl, but they did not play a direct role in her death.
Law enforcement sources said it was likely that Ms Houston had a heart attack that caused her to lose consciousness and drown in the bath at the Beverly Hilton Hotel.
The heart attack was probably brought on by the hardening of her arteries as a result of years of cocaine abuse.

Following the news, Houston's family have released a statement that says: 'We are saddened to learn of the toxicology results, although we are glad to now have closure.'
And her mother Cissy Houston is reported to be 'shocked' to learn that her daughter was still using drugs at the time of her death.
