According to NBC News, movie star Carrie Fisher had several drugs in her system at the time of her death.
The report says the world-famous "Star Wars" actress tested positive for cocaine, methadone, alcohol and opiates, but investigators could not determine whether those drugs contributed to her death in December. Coroner's officials have ruled Fisher died from sleep apnea and a mix of "other undetermined factors."
She also had traces of heroin and ecstasy, NBC reports.
The report says there were traces of heroin and ecstasy drug MDMA in Fisher's system, but investigators could not determine when she had taken those drugs or what role they played in her death.
The actress and writer died in December at the age of 60. Her mother, actress Debbie Reynolds, died one day later.
She also suffered from "drug use" and atherosclerotic heart disease, a condition in which fats, cholesterol and other substances build up on the artery walls, the statement said.
Fisher's daughter, Billie Lourd, said after the medical examiner's report was released that her mother "battled drug addiction and mental illness her entire life" stating that "she ultimately died of it."
"She was purposefully open in all of her work about the social stigmas surrounding these diseases," Lourd said in a statement.
"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," she added.
Fisher's death came four days after she suffered a cardiac event on a flight from London to Los Angeles.
