The final coroner's report relating to Whitney Houston 's death has revealed that traces of several drugs were found in her system, the Guardian reports today (April 5, 2012). Those drugs that are listed in the report - the most comprehensive analysis if her cause of death to have been released - are "cocaine, marijuana, the allergy medicine Benadryl, the muscle relaxant Flexeril and the anxiolyitc Xanax," as well as a mixture of illegal and prescription drugs.
According to the report, police arrived at the scene to find Whitney Houston face down in a bathtub full of water "hot enough to have burned her back." It was also noted that blood was coming from her nose. In her report, Kristy MCCracken of the Beverly Hills Police Department wrote that the late singer had "possibly overdosed on a narcotic substance, prescription medications, over the counter medications and alcohol." Huston had apparently been complaining of a sore throat on the day of her death. Her assistant suggested that she take a bath and briefly left the hotel. When she returned, she found Houston face down in the overflowing tub. The doctors that performed the autopsy have confirmed that the cause of death was a combination of atherosclerotic heart disease and cocaine use.
