It's common knowledge that smoking can lead to cancer and heart disease. In addition, smoking is also a risk factor for asthma in children and a common trigger of asthma for people of all ages.
People with asthma should not smoke, and they should also avoid secondhand smoke. This "passive smoking" can trigger asthma symptoms in people with asthma. Children exposed to secondhand smoke are more likely to suffer from bronchitis, pneumonia, ear infections, coughing, wheezing, and more frequent and severe asthma attacks.
If you have asthma and smoke, or if you smoke and live with someone with asthma, it's important that you quit smoking. Talk to your healthcare provider for advice and guidance on starting an effective treatment program to help you quit smoking.
