Quit, the anti-smoking charity, has produced a guide for health professionals specifically tailored to help single parents kick the smoking habit.
Research carried out by the charity shows that three-quarters of all lone parents in Britain smoke, despite the fact that they are disproportionately represented in the lowest income group.
"I can't afford to smoke, but I can't bear not to" is the most common excuse given by smokers in that particular demographic, according to Quit.
The guide, called Supporting Change, contains all the topics health professionals might want to raise with parent smokers, such as how children are harmed by passive smoking, and how to help parents discourage their children from taking up the habit.
It also advises that if a parent is a committed, contented smoker with no wish to quit, there is hardly any point in pushing them to stop. In this instance, the guide advises health workers to discuss ways of ensuring that their child breathes smoke-free air instead.
The Supporting change report is available free from Quit, and was made possible through a grant from the Community Fund.
