Smoking

Asthma can be triggered by many things and cigarette smoke, with its 4,000 harmful chemicals, is a major trigger.

When you have asthma your airways are extra sensitive, the airways can be come inflamed (red and swollen) and extra mucous can be produced.

Tobacco smoke damages the cilia (little hair-like structures) which move dust, pollens and other irritants from your lungs.  This makes you more prone to chest infections which in turn brings on or worsens your asthma.

People with asthma who smoke have more respiratory symptoms, more airway inflammation, an accelerated decline in lung function and worse asthma control. In addition, research suggests that people with asthma who smoke don’t respond as well to preventer medication compared to non-smokers.

Passive Smoking

Passive smoking can also trigger an asthma attack or increase the number of attacks you have. It can also increase your need for asthma medications and your sensitivity to other environmental triggers eg pets, pollens and chemicals and reduce your lung function.

If you can't avoid smoky areas, make sure you always keep your day-to-day asthma under control.  You should not need to use your reliever medication more than 3-4 times a week (excluding before exercise medication).

You may need to take some reliever medication before entering a smoky environment.

Smoking and Pregnancy

A woman smoking during pregnancy passes on chemicals in the cigarette smoke to the foetus, affecting the cells of the developing lungs.  This may increase the baby’s chances of having lung problems such as asthma. Smoking has also been linked to Sudden Infant Death Syndrome (SIDS).  Babies of smokers are more likely to suffer from asthma and respiratory infections than those of non-smokers.  Research has shown that children exposed to second-hand smoke after birth are likely to develop respiratory problems such as wheezing or may experience worsening of pre-existing asthma or other acute respiratory illness.  

Quitting Smoking

Quitting smoking can be very difficult, but many smokers find it easier than expected.  It can be done and you will find very definite benefits in your health and the quality of your life. Talk to your doctor or asthma educator about how nicotine-replacement therapy, counseling and other treatments can help you butt out for good.
