The L.A. County Coroner released its full autopsy on Monday, and it revealed that Fisher may have taken cocaine approximately 72 hours before her flight on Dec. 23. In addition, traces of heroin and MDMA -- also known as ecstasy -- were also present in her system, but they could not determine when Fisher had taken those drugs.
"Drugs of abuse such as cocaine, heroin and amphetamine derivatives are very difficult to interpret based on quantitative levels in tissues or blood postmortem," the report reads. "Ms. Fisher suffered what appeared to be a cardiac arrest on the airplane, accompanied by vomiting, and with a history of sleep apnea. Based on the available toxicological information, we cannot establish the significance of the multiple substances that were detected in Ms. Fisher's blood and tissue, with regard to her death."
