Cocaine ‘damaged Winehouse’s lungs’

Amy Winehouse could struggle to catch her breath and hit high notes as a result of suffering emphysema, a lung expert has said.

The singer’s father spoke out at the weekend about his worries that Winehouse could lose her life unless she kicks her drug habit.

In an interview with the Sunday Mirror, Mitch Winehouse said his daughter – who was rushed to hospital recently after collapsing – had developed the chronic lung disease emphysema, possibly brought on by smoking crack cocaine.
