Carrie Fisher, who died last December, had a mix of drugs in her system when she became ill on a flight last year.
The Associated Press reported that Fisher had cocaine, heroin and ecstasy in her system, although it's unclear what impact the substances might have had on her death.
"At this time the significance of cocaine cannot be established in this case," the full autopsy report, released Monday, states.
The findings also surmise that Fisher had taken the cocaine three days before had suffered a heart attack on a transatlantic flight on Dec. 23. She died four days later. While heroin is detectable in the system for a period of time after ingesting, it's unclear when that and the ecstasy were taken.
The results come from toxicology screenings that were taken when Fisher arrived at the hospital.
Los Angeles County coroners had previously stated drug use was a factor in the actress's death. Specifically, the autopsy said it was due to a combination of factors including sleep apnea and "other conditions: atherosclerotic heart disease, drug use."
"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 the cause of death," the report stated.
Fisher had been open about her struggles with drug addiction and mental illness, including bipolar disorder. She had stated she was on medication to treat that condition.
"My mom battled drug addiction and mental illness her entire life. She ultimately died of it. She was purposefully open in all of her work about the social stigmas surrounding these diseases," Fisher's daughter, Billie Lourd, said in a statement given to People Magazine.
