June 19 (UPI) -- Carrie Fisher had heroin and cocaine in her system at the time of her death, according to a toxicology report.
The report obtained from People magazine from the Los Angeles County coroner's office on Monday, also showed that the actress had methadone, ethanol and opiates in her system when she died at the age of 60 in December.
"The exposure to cocaine took place sometime approximately in the last 72 hours of the sample that was obtained," the report notes.
"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," it continued.
On Friday, the Los Angeles Country coroner's office announced that sleep apnea and other factors, including drug use and heart disease, contributed to her death.
"My mom battled drug addiction and mental illness her entire life," Fisher's daughter, actress Billie Lourd said in a statement at the time. "She ultimately died of it. She was purposefully open in all of her work about the social stigmas surrounding these diseases. She talked about the shame that torments people and their families confronted by these diseases. I know my Mom, she'd want her death to encourage people to be open about their struggles. Seek help, fight for government funding for mental health programs. Shame and those social stigmas are the enemies of progress to solutions and ultimately a cure. Love you Momby."
