Carrie Fisher had heroin and cocaine in her system at the time of her death, according to her toxicology report.
PEOPLE obtained official documents from the Los Angeles County coroner’s office on Monday that reveal the late actress had cocaine, methadone, ethanol and opiates in her system when she passed away 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,” stated the report.
The report also stated that Fisher had a “remote exposure to MDMA,” which is a commonly known as ecstasy.
The toxicology report also found traces of an anti-depressant and antihistamine in her system.
Though Fisher had multiple substances in her system, it is unclear if drug use ultimately contributed to her death.
“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,” stated the report.
An external examination was conducted on Fisher’s body as her family objected to an autopsy.
On Friday, the Los Angeles County Coroner’s Office revealed Fisher’s death was caused by sleep apnea and other undetermined factors.
The coroner also said Fisher suffered from atherosclerotic heart disease and “drug use,” but no specifics were given at the time.
“The manner of death has been ruled undetermined,” the report concluded.
In an exclusive statement to PEOPLE, Fisher’s only child, Billie Lourd, addressed the report.
“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.
“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.”
