Bad boy Charlie Sheen gets chilling warning over his 40-a-day smoking habit on Dr Oz show

He's the unashamed wild man of Hollywood who once boasted of having the lungs of a non-smoker despite puffing on 40 cigarettes a day.
But Charlie Sheen was given some food for thought on Tuesday as he was confronted by the grisly reality of his nicotine habit.
Appearing on the Dr Oz television show, the former star of Two and a Half Men was shown the stark contrast between the lungs of a healthy person and those of a long-term tobacco user.

Health warning: Heavy smoker Charlie Sheen was shown the devastating effects of tobacco use in an appearance on the Dr. Oz show in New York

The show's host, top cardiologist Dr Mehmet Oz, left the 47-year-old actor in no doubt about the likely effect his heavy smoking habit was having on his body as he showed him the blackened, necrotic lung of a smoker.
Whether shock treatment is enough to change Charlie's wild ways remains to be seen.
However the actor was given a happy reason to take his long-term health seriously this week after confirming the news that he is to be a grandfather.
In an appearance on The Late Show With David Letterman on Monday, the Anger Management actor revealed that his 28-year-old daughter Cassandra Estevez and her husband were expecting their first child.
'Me as grandfather, Dave...I don't know. It's like the world's going to crack in half,' he joked to Letterman.

Concern: Charlie was shown the stark contrast between a healthy lung and one blackened by years of smoking.

But he added: 'It's fabulous. It's just not a title I'm ready to adopt.'
Cassandra is Sheen's daughter with his high school girlfriend Paula Profit, and was born when he was 19. He gave her away in 2010 when she married her high school sweetheart Casey Huffman.
Along with his oldest daughter Sheen is also a father to daughters Sam, eight, and Lola, seven, with second wife Denise Richards, and three-year-old twins, Bob and Max, with third wife Brooke Mueller.
Sheen, who now stars in the FX series Anger Management, was fired from Two and a Half Men in March 2011 and attacked the show's creator Chuck Lorre over the following few months on stage, on Twitter and in the press.
