18% of all deaths in adults aged 35 or over in England are still attributable to smoking. Almost all these premature deaths could be avoided if smokers stopped before their mid-thirties but only a quarter of people who have ever smoked regularly manage to quit by this age. GP advice is one of the most important triggers to a smoker making an attempt to quit. Evidence shows that offering help to all smokers is easier, quicker and likely to be more effective than just advising smokers to stop or asking whether they are interested in quitting.
