Traces of cocaine, heroin and ecstasy found during Carrie Fisher's autopsy.

Carrie Fisher’s autopsy report shows the actress had cocaine in her system when she fell ill on a plane last year, but investigators could not determine what impact the cocaine and other drugs found in her system had on her death.

The report released on Monday states Fisher may have taken cocaine three days before the December 23 flight on which she became ill. She died four days later, aged 60.

She died four days later, aged 60.

The toxicology screening also found traces of heroin and MDMA (also known as ecstasy) in the actress’ bloodstream but doctors could not determine when Fisher had taken those drugs.

The findings were derived from blood samples taken when the Star Wars actress arrived at a Los Angeles hospital following the fateful plane flight.

Coroner's officials ruled Fisher died from sleep apnea and a combination of other factors.

A day after her death, on December 28, Fisher's mother, actress Debbie Reynolds, 84, died from a brain hemorrhage.
