Further autopsy details have revealed a hole in her nose and 11 missing teeth, possibly caused by years of drug and alcohol abuse including cocaine rotting her gums. She also had a needle mark on an arm at the time of her death, The Sun reports.
Houston's autopsy report was released earlier in the week and confirmed that the singer's accidental drowning was likely brought on by a possible overdose "on a narcotic substance, prescription medications, over the counter medications and alcohol".
The coroner also listed "chronic" cocaine use and heart disease as contributing to Houston's death. A total of nine drugs were discovered in her body following her death.
It is believed the singer's skin was burned by the bath's water, which sources say could have been 66°C (150°F). Houston may not have noticed how hot the bath was if she had taken drugs, it is claimed.
A spoon covered with cocaine was also found in her hotel suite at the Beverly Hilton hotel. Traces of the drug were found in her system along with marijuana, anxiety pills Xanax, muscle relaxant Flexeril, allergy medicine Benadryl and painkiller Ibuprofen.
Houston had marks on her stomach, chest and upper left thigh, thought to be from cosmetic surgery including breast implants.
A scar on her inner left forearm is said to have been self-inflicted after she was seen leaving a club with her legs and arms dripping blood days before her death.
