Amy doesn't do drugs anymore: Mum

London, Aug 2 : Troubled popstar Amy Winehouse's mum Janis is absolutely sure that her famous daughter no longer uses drugs as a result of her major health problems.

Janis insists that her daughter's health problems and recent visit to the hospital have petrified Winehouse.

"I really don't think she's using (drugs) now, being diagnosed with the early stage of emphysema was a real jolt to her, a bit of a wake-up call," the Mirror quoted Janis, as saying.

The 'Back to Black' singer, who had been diagnosed with emphysema, a deadly lung disease, is eventually on the road to recovery, believes Janis.

"She's got a constant P.A. by her side, a minder - plus there's a security guard watching her, I think things are really beginning to take shape to the good," she added.
