Amy Winehouse's mother Janis is convinced her troubled daughter no longer uses drugs - insisting the star's recent health problems have scared her off illegal substances forever.

The Back To Black hitmaker was admitted to hospital in June after falling ill at her London home.

She was later diagnosed with traces of deadly lung disease emphysema.

And the singer's mum believes the health scare has finally put the 24-year-old on the road to recovery.

She tells British newspaper The Daily Mirror, "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.

"She's got a constant P.A. (personal assistant) 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."
