Tobacco use remains the leading cause of preventable morbidity and mortality worldwide.

Smoking causes a range of illnesses, including respiratory disease, cancer, circulatory disease and diseases of the digestive system.  Smoking is harmful not only to smokers but also to people around them.  Infants of parents who smoke are more likely to suffer from serious respiratory infections. It is a major cause of health inequalities. 

Addressing smoking is through Tobacco Control Initiatives that includes both the provision of Stop Smoking Services and wider efforts to create smoke free environments.

The prevalence of smoking varies markedly between socio-economic groups.  Smoking prevalence is higher in more deprived populations and amongst the routine and manual group of workers.

Smoking is the single most modifiable risk factor for adverse outcomes in pregnancy.
