An autopsy revealed actress Carrie Fisher had cocaine, ecstasy and heroin in her system when she died.
Medical examiners say it's unclear if the drugs played any role in Fisher's death, previously reported to be the result of sleep apnea, reports the Los Angeles Times.
In addition, it's uncertain when exactly Fisher took the substances -- although it is believed she took the cocaine 72 hours before she was hospitalized on Dec. 23, 2016.
In life, Fisher was open about her struggle with drugs and mental illness, the Daily Mail reports. At one point, the star -- who was diagnosed with bipolar disorder -- even had a near-fatal overdose in the 1980s.

Consequently, she had been in rehab on and off and underwent electroshock therapy for drug addiction.
As a result, despite what medical professionals say, some believe it was the drugs that ultimately took Fisher's life.
"My mom battled drug addiction and mental illness her entire life," wrote the star's daughter, Billie Lourd. "She ultimately died of it. 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."
Social media users also believed she died of drugs, yet responded differently.

Some, like Lourd, showed empathy.
"It's really sad that even after all they had done to her and her career she was never able to fully conquer her demons," wrote one Daily Mail reader. "A lesson for everyone. There is no magic pill that will make everything better, whether it comes from a dealer or a doctor."
While many felt compassion, some were less forgiving.
"Someone needs to say it, so I will: Carrie, You had a child," added another. "You had family that loved you. A pet who lived for you and was dependent on you. You were in your 60s. You had the best medical and psychological treatment money could buy, yet you died with two illegal uppers and one illegal downer in your system on a flight home. In your 60s. Enough with the excuses you constantly wrote and talked about. You were no better than the drug gies we see unconscious on the side of a road with kids in the back seat. Your humor doesn't excuse the horrible way you let down your daughter and killed your mother."
