The family issued a statement that "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.”

Although illegal drugs were not detected, the family says the toxicology reports showed "alcohol was present" in her system at the time of her death. No word on whether prescription drugs were named in the toxicology report.

Winehouse, 27, was found dead on July 23 inside her London home.

The family plans to create a foundation in Amy's honor for those struggling with addiction.
