BREAKING NEWS - Amy Winehouse Had No "Illegeal Substances" In Her System After Autopsy

Perhaps Amy Winehouse didn't overdose after all.

One month after she was found dead in her London home, the "Rehab" singer's family has announced that toxicology tests have come back -- and they prove Winehouse had no "illegal substances" in her system when she passed on July 23.

Still, that doesn't rule out any legal prescription drugs prescribed to her at the time.

The family's spokesman Chris Goodman also says that "alcohol was present" in her system, but it has yet to be determined what role, if an, it played in her death.

The statement also said the family is awaiting the outcome of an inquest that will begin in October.

Winehouse, who had a long history with drugs and alcohol, was discovered in bed by a bodyguard on the afternoon of July 23. It was reported that she had been dead up to six hours.

Although several reports suggested Winehouse went on a drug and alcohol binge the night before after buying cocaine, heroin, ecstasy and ketamine, a police source told the Sun that no drugs or paraphernalia were found in Winehouse's North London home.

In addition, the Grammy-winning singer had been examined by a doctor that night as part of a routine checkup - and she seemed to be in fine health.
"The doctor was happy with her condition," a source told The Sun last month. "When he left on Friday night he had no concerns. Less than 24 hours later she was found dead."

Winehouse's father, Mitch, has said his daughter had beaten her drug dependency three years before her death, but he admitted she was still struggling to control her drinking after several weeks of abstinence.

He told mourners at the singer's July 26 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.'"

The Winehouse family announced plans to establish a charitable foundation in the singer's name to help people struggling with addiction - although Mitch Winehouse has said the plans are on hold because someone else had registered the name Amy Winehouse Foundation.
