Amy Winehouse Toxicology Results Revealed: Drugs Not Found

Amy Winehouse's toxicology results have been revealed, and while alcohol was present in her system, no illegal substances were found, leaving her cause of death still a mystery.

A statement released by spokesman Chris Goodman, via The Asssociated Press, on behalf of singer's family said, "toxicology results returned to the Winehouse family by authorities have confirmed that there were no illegal substances in Amy's system at the time of her death."

The toxicology results did show, however, that "alcohol was present" in Amy's system, but it has yet to be determined if it played a role in her death.

Amy was found dead in her London home on July 23. She was only 27.

The five-time Grammy winner battled addictions throughout her time in the public spotlight.

Her father, Mitch Winehouse told mourners at Amy's funeral in July that she had said to him, "'Dad I've had enough of drinking, I can't stand the look on your and the family's faces anymore.'"

The Winehouse family has plans to establish a foundation in Amy's honor to help those battling with addiction.
