Amy Winehouse had no illegal drugs in her body when she died last month.

The results of toxicology tests show that late singer, who was found dead in her Camden home on July 23, had no illegal drugs in her system, but that alcohol was present. The results did not determine a cause of death and it’s unclear whether the alcohol played a role in her passing, the Associated Press reports.

Winehouse, who died at the age of 27, very publicly struggled with drugs and alcohol, leading some to conclude that her death was the likely result of an overdose. These findings suggest that was not the case, though it’s unclear whether her addictions caused health problems that led to her demise.

An inquest into the cause of Winehouse’s death is scheduled to resume in October.

In other Winehouse-related news, Mitch Winehouse, father of the “Back to Black” songstress, was recently forced to slow down plans to create a charity called the Amy Winehouse Foundation after the online domain name was purchased by a British Internet opportunist. According to the Daily Mail, Mitch Winehouse recently returned donations to the foundation from fans and is attempting to resolve the matter.
