Smoking can cause a number of illnesses and 22% of all male deaths and 11% of all female deaths are due to smoking.
Second-hand smoke is other people's tobacco smoke and can also lead to heart disease and lung cancer, and make illnesses like asthma worse. The effects of second-hand smoke on children can be more serious because their bodies are still developing.
Smoking can cause bad breath and make clothes and furniture smell.
However, by giving up smoking you can reduce the risk of developing many smoking related illnesses. Within 10-15 years of giving up, an ex-smokers' risk of developing lung cancer is only slightly greater than someone who has never smoked.
