Health risks of passive smoking

Secondhand smoke comes from the tip of a lit cigarette and the smoke that the smoker breathes out.

Breathing in secondhand smoke – also known as passive smoking – increases your risk of getting the same health conditions as smokers. For example, breathing in secondhand smoke increases a non-smoker's risk of developing lung cancer by about a quarter.

Babies and children are particularly vulnerable to the effects of secondhand smoke. A child who is exposed to passive smoke is at increased risk of developing chest infections, meningitis, a persistent cough and, if they have asthma, their symptoms will get worse. They're also at increased risk of cot death and an ear infection called glue ear.
