According to a toxicology report, alcohol was present but no illegal street drugs were found in British singer Amy Winehouse’s system after she died suddenly at age 27 in her $4 million London flat last month.

Winehouse’s spokesman released a statement confirming alcohol was present in her system. “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 statement read.

The spokesman added: “Results indicate that alcohol was present but it cannot be determined as yet if it played a role in her death.”

Amy’s father Mitch said she successfully kicked her drug habit that plagued her for years.

“Three years ago, Amy conquered her drug dependency — the doctors said it was impossible but she really did it,” he said.

But reports quoted family sources as saying her death could have been caused by sudden alcohol withdrawal.

“She was trying hard to deal with her drinking and had just completed three weeks of abstinence. She said, ‘Dad I’ve had enough of drinking, I can’t stand the look on your and the family’s faces anymore.’ ”
