Carrie Fisher Had Cocaine and Opiates in Her System at Time of Death

“My mom battled drug addiction and mental illness her entire life. She ultimately died of it," the late actress' daughter said.

Carrie Fisher had cocaine and opiates in her system when she died of a heart attack last December, according to a coroner's report obtained by The Hollywood Reporter.

In addition to the aforementioned substances, the late Star Wars actress had methadone in her system, according to the report from the Los Angeles County medical examiner's office.

The family objected to a full autopsy, the report notes.

Despite the substances discovered through toxicology tests, the medical examiner said it was unclear how much of a role those played in Fisher's death.

The report states Fisher died of "sleep apnea and other undetermined factors."

Fisher suffered cardiac arrest while aboard a London to Los Angeles flight on Dec. 23. She died Dec. 27. She was 60.

As news broke of the report content, Fisher's daughter, Billie Lourd, released a statement to People.

“My mom battled drug addiction and mental illness her entire life," Lourd said. "She ultimately died of it. She was purposefully open in all of her work about the social stigmas surrounding these diseases."

She continued, "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.”
