Whitney Houston cause of death revealed!Her last cocaine sniff exacerbated Houston’s heart condition and led to her accidental drowning in the bathtub of a Beverly Hills hotel suite last month.

The long-awaited autopsy results were released Thursday after weeks of profound speculation over how the 48-year-old pop star died. It marks another high-profile Hollywood death connected to drug use, coming less than three years after Michael Jackson died suddenly at his Holmby Hills mansion.

Michael Jackson’s death resulted from intoxication involving a powerful anodyne, and Jackson’s  doctor was later convicted of involuntary manslaughter.

Whitney Houston had battled with drug addiction for many years, and the coroner’s office found traces of various drugs, incl. marijuana, the anti-anxiety drug Xanax, the muscle relaxant Flexeril and Benadryl in her system. But the coroner’s office educed that those drugs were not cause of Houston’s death.

Cocaine kills a lot of people, Whitney Houston became latest victim

Cocaine did play a role, though officials said they were still trying to arrange how much cocaine was in her system. In an reportage with ABC News in 2002, Whitney Houston acknowleged using cocaine as well as marijuana and also drinking heavily at times. She strongly denied accusations of using crack cocaine.

Whitney Houston said that “Crack is cheap. I make too much money to ever smoke crack,” and also “Let’s get that straight. OK? We don’t do crack. We don’t do that.”

Cocaine has played a role in several high-profile deaths among prominent names in the entertaining business. In 1982, famaous comedian John Belushi died of a combined injection of cocaine and heroin known as a speedball at the Chateau Marmont on the Sunset Strip. Fellow “Saturday Night Live” peformer Chris Farley also died of an accidental overdose of mixed cocaine and morphine in Chicago in 1997.

Whitney Houston made friends laugh just hours ahead of her death

That Thursday, she dropped by the rehearsals for the pre-Grammy party. A Grammy staffer said that as reporters interviewed Davis and singers Brandy and Monica, Whitney Houston was dancing just off camera to make them laugh.

Whitney Houston was found submerged in the bathtub of her hotel room on the afternon of Feb. 11 by an assistant. Beverly Hills Fire Department paramedics performed artificial respiration on Whitney Houston for about 20 minutes before pronouncing her dead.
