Robin Williams' Toxicology Report Reveals No Alcohol or Illicit Drugs at Time of Death

The comedian had been taking prescription medications.

“Since his passing, all of us who loved Robin have found some solace in the tremendous outpouring of affection and admiration for him from the millions of people whose lives he touched. His greatest legacy, besides his three children, is the joy and happiness he offered to others, particularly to those fighting personal battles," the statement read. "Robin's sobriety was intact and he was brave as he struggled with his own battles of depression, anxiety as well as early stages of Parkinson's Disease, which he was not yet ready to share publicly."

The coroner also ruled Williams' death at 63 a suicide by hanging, which resulted in asphyxia.

The Oscar winner was found dead in his Tiburon, California, home on Aug. 11.

"Robin Williams passed away this morning," the actor's rep Mara Buxbaum told ABC News at the time. "He has been battling severe depression of late. This is a tragic and sudden loss."
