(AP Photo/Joel Ryan, file) (Newser) – More tragic details from Whitney Houston's final autopsy report: The singer drowned in a bathtub, face down in "extremely hot" water, and had scalding burns on her body. Houston had complained of a sore throat before her death, and an assistant suggested a bath. The coroner's investigation ultimately concludes that heart disease and cocaine use both contributed to her death, although the amount of cocaine in her system was not toxic, an expert tells the Los Angeles Times. It was previously reported that cocaine and a drug spoon were found in Houston's room. TMZ has even grimmer portions of the report: Houston had a "bloody purge coming from her nose" and a perforated posterior nasal septum, indicative of her history of drug abuse. Ultimately, the report states, Houston "possibly overdosed on a narcotic substance, prescription medications, over the counter medications, and alcohol," though her official cause of death remains accidental drowning. In addition to cocaine, Houston had traces of marijuana, Xanax, Benadryl, and a muscle relaxer in her system when she died.
