Cigarette Smoking & Asthma

Avoidance of passive and active smoking is the most important control measure for both adults and children with asthma. 

Broken cigarette

At least 75% of people with asthma become wheezy in a smoky room. It has been shown that children with asthma whose parents smoke have more asthma episodes than children whose parents don't smoke.

  • If you smoke or are exposed to passive smoke you increase the risk of asthma attack and may permanently damage your airways.
  • If you smoke as a teenager you increase the risk of your asthma persisting
  • You put your children at risk of asthma if you smoke around them or during pregnancy
  • You also increase the risk of developing Chronic Obstructive Pulmonary Disease (COPD). COPD is a term used to describe any one of a combination of chronic bronchitis, emphysema and chronic asthma.
