So far there's been no confirmation from an actual medical examiner, but at least this seems to rule out her family's own (ridiculous) theory that Amy died of alcohol withdrawal. Winehouse's family, it should be noted, is not the most reputable source of information -- as The Amp wrote earlier this week, the Amy Winehouse Foundation the singer's father, Mitch, vowed to set up is currently on hold because he failed to secure the name "the Amy Winehouse Foundation."
If in fact the Winehouse family's statement offers a sneak preview of the investigation that will begin in October, illegal substances like heroin, cocaine, and crack -- all drugs Winehouse was accused of using during her downward spiral -- can be ruled out as contributing to her death. The phrase "no illegal substances" is elusive, though: It doesn't completely rule out legal substances being used illegally, which would be the case of prescription drugs or (as rumored) the sedative Ketamine. It also opens the possibility of an alcohol poisoning-related death (like Led Zeppelin's John Bonham), or simply perhaps the years of drug and alcohol abuse just took its irreparable toll on Winehouse. We'll know for certain in October.
