Todd Fisher does not believe that the results of his sister Carrie Fisher's autopsy should negatively affect her legacy.
On Monday, the L.A. County Coroner released its full autopsy, which showed that cocaine was among the drugs in the actress' system when she died in December at age 60. However, investigators could not determine what impact the drugs in her system may have had on her death.
"I would tell you, from my perspective that there’s certainly no news that Carrie did drugs," Todd told ET after the autopsy results were revealed. "If you want to know what killed her, it’s all of it."

"Without her drugs, maybe she would have left long ago," he added. "I am not shocked that part of her health was affected by drugs.”
Todd also came to the defense of the doctors that prescribed his sister medication, telling ET, "They were doing their best to cure a mental disorder. Can you really blame them?"
The report also showed that Carrie may have taken cocaine approximately 72 hours before her flight on Dec. 23. In addition, traces of heroin and MDMA -- also known as ecstasy -- were present in her system, but investigators could not determine when she had taken those drugs.
Carrie's brother went on to praise the Star Wars actress' fans for their dedication and kind comments following the release of the autopsy report. “We are touched by the outpouring and overwhelming support from her fans," he said. "The few negative comments are crushed by them, they come to her defense and allow us to rest.”

The actress' sister, Joely Fisher, also shared a statement with The Insider regarding the findings in Carrie's autopsy report. “She spent a lifetime well documenting her dance with demons. It's a shame we can't hear her own words regaling us with this final kick line," Joely noted. "Do not let this change the way you feel about my brilliant sister. She was a lot of things to a lot of people, but never a liar. She lived hard, let her rest. She is a hero for all those suffering from mental illness and drug addiction and once again she is controlling the narrative brilliantly.”
Prior to the release of the autopsy report, the Medical Examiner's office concluded on Friday that Carrie died of sleep apnea and other undetermined factors. They also determined that atherosclerotic heart disease and drug use contributed to her death.
In addition to her siblings, Carrie's daughter, Billie Lourd, released a statement to ET in regard to the Medical Examiner's findings. "My mom battled drug addiction and mental illness her entire life. She ultimately died of it," the 24-year-old actress said. "She was purposefully open in all of her work about the social stigmas surrounding these diseases."
