Singer Amy Winehouse had no illegal substances in her system when she died last month, says her family.
A statement released by a family spokesman 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 tests did show "alcohol was present," but the cause of death is still unclear.
The soul diva, who had battled drug and alcohol addiction for years, was found dead at age 27 in her London home on July 23.
Winehouse's father, Mitch, told mourners at the singer's July 26 funeral that his daughter was still struggling with an alcohol dependence but 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 announced plans to establish a charitable foundation in the singer's name to help people struggling with addiction.
