It sounds possible!
Last week Amy Winehouse collapsed outside her home and was rushed to the hospital. After she spent a week their her father, Mitch Winehouse, is opening up about her health. Mitch told BBC Radio,

"Amy really hasn't got emphysema, there's traces of emphysema. Obviously, if she doesn't quit smoking, it's going to get worse, like everyone else ... with patience her lungs will recover completely."

As far as what caused the damage...Mitch told People Mag that it's from smoking none other than crack cocaine and all those cigs. But no worries fans....her father says she will still be performing. We think Amy might want to purchasing an oxygen tank soon, unless she can kick the habit.
