Amy Winehouse’s long-suffering father Mitch has revealed that the singer has contracted emphysema and could be confined to a wheelchair within a month if she doesn’t quit drugs.

In an emotional interview the cab driver told how doctors have warned his daughter – who was rushed to hospital last week – that she may be forced to wear a permanent oxygen mask to survive if she doesn’t follow medical advice.

‘To think this could be my beautiful 24-year-old daughter's life is preposterous. But if drugs mean more to her than breathing properly, then so be it.

‘But the doctors have told her if she goes back to smoking drugs it won't just ruin her voice, it will kill her.’ He said.

Winehouse collapsed at her North London home last week and was taken for tests at a London hospital by her father.

The extent of her condition has put in doubt her appearance at the Nelson Mandela birthday concert in Hyde Park on Friday with concerns that she may also pull out of Glastonbury the following day.

Mitch Winehouse has urged her drug dealers and addict friends such as rocker Pete Doherty – who has been spending time with the 24-year-old since his release from prison last month – to stay away from her.

‘I'm saying to those drug dealers, and they know who they are, if they are supplying crack to Amy, then they've got to take responsibility. I don't want her hanging out with her mates like Pete Doherty either.’ He said.

He revealed that the singer’s 26-year-old husband Blake Fielder-Civil – who is awaiting sentence after pleading guilty to GBH and conspiring to pervert justice - has vowed to come off drugs and has been calling her every day 'to help her stay strong'.

‘Blake apologised to me for getting Amy into drugs and says he's going to try and put it right.

‘Blake was clean when I saw him but he's told me he wants to go into rehab. We've organised it so that as soon as he's out, that happens.

‘He wants to go from zero to hero. It's very hard for him being in prison, but at least he's been trying.’ He said.

Emphysema – usually caused by smoking - is a progressive lung condition which ages the lung’s prematurely and leaves sufferers struggling for breath.

The damage caused by the disease is irreversible and can lead some sufferers to become dependent on oxygen supplies.

The 57-year-old – who split from the troubled star’s mother Janis when she was a teenager – says that she is in the ‘early stages of the illness’.

‘The doctors have said that if she had continued the way she was going she could have ended up an invalid - she wouldn't have been able to breathe.

Sad, so sad
