Those who made new year's resolutions to quit smoking have been urged not to give up.
Martin Dockrell, campaigns manager at Action on Smoking and Health (Ash), said that people who seek professional help are four times more likely to quit than those who try to do it on their own.
He explained that most individuals do not realise how hard it is until they have tried it.
"It is highly addictive and it is very difficult to quit. That is why many smokers have at least two attempts at quitting and that is okay," stated Mr Dockrell.
He added that it while it was acceptable to fail once or twice when trying to stop smoking, it was important not to "give up on giving up".
According to the latest figures from Ash, around ten million people smoke in the UK, with 22 per cent of men and 21 per cent of women having the habit.
