A coroner's report on Carrie Fisher's autopsy, released Monday, revealed traces of cocaine, heroin and ecstasy in the actress's system when she went into cardiac arrest on a flight last year and died four days later.
The report said Fisher may have taken cocaine three days before the Dec. 23 flight, but could not determine when she took the other drugs.
Investigators could not confirm the impact the drugs had in regard to her death. Last year, coroner's officials ruled Fisher died from sleep apnea and a combination of other factors.
Fisher’s daughter, Billie Lourd, issued a statement to People magazine Friday night linking her mother’s death to drug use.
“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,” Lourd told People.
