Was Amy Drugged-- Involuntarily?

In another strange twist to the Amy Winehouse saga, The Sun revealed a source claiming that Mitch believes that his daughter was drugged. Instead of suffering convulsions due to her medication, Amy's dad thinks that she was slipped some E:

"[Mitch] is convinced that one of her hangers-on was responsible and he's waiting for a toxicology report to show what caused her to fit. If his suspicions are proved right, he wants someone to be punished. He is seriously unhappy about Amy's flat being a stop-over for randoms and wants an end to it."

Anything is possible, but honestly, it's not like Amy's exactly been staying in lately. One thing that I do know for sure: this isn't the end of it!
