Daniel Radcliffe's pack-a-day cigarette habit has become so apparent that his co-stars on the set of 'Harry Potter and the Half-Blood Prince' - have nicknamed the 18-year-old 'Harry Puffer". A source said: "Daniel has been smoking up to 20 cigarettes a day. Every time they call 'cut', he lights up. It's disgusting.
"Friends, including co-stars Rupert Grint and Emma Watson, have been warning him about the dangers of smoking. But he doesn't take any notice."
Daniel is at a stage in his life when he wants to appear older and more mature, yet the movie's producers would prefer he not publicly display his smoking habit, which could tarnish his young wizard image, and have reportedly told him not to smoke in places where he might be photographed.
The source added that Daniel doesn't listen: "He's been having late nights out with stars including Kevin Spacey and Stephen Fry and been puffing up a storm."
