The family said in a statement that toxicology tests showed “alcohol was present, ” but it hasn’t yet been determined if it contributed to her death.
A statement released by spokesman Chris Goodman on the family’s behalf 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.”
It said the family awaited the outcome of an inquest that is due to begin in October.
According to Amy’s father, Mitch Winehouse, she had quit drugs, but was still struggling with alcohol.
He told mourners at Amy’s funeral 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.'”
