Smoking causes 100,000 premature deaths a year in the UK alone, mostly from diseases affecting the lungs and heart. Cigarette smoke contains carbon monoxide and damages the air passages of the lungs, causing them to narrow, and therefore anyone with asthma should not smoke. If you are already a smoker and want to stop this harmful habit, make the decision today to stop now. Motivation is very important if you are to be successful and you should not embark on this course in a half-hearted manner.
If you need help or guidance, ask your doctor for advice on giving up. You may even be able to join a local stop smoking group in your area. Because smoke is an irritant, you will soon notice an improvement, often within 24 hours of quitting.
