Smoking and Asthma Don’t Go Together
Things that make your allergies or asthma worse are called triggers. Smoking is a trigger for many people who have asthma.
You do not have to be a smoker for smoking to cause harm. Exposure to someone else's smoking (called secondhand smoke) is a trigger for asthma attacks in children and adults.
Smoking can weaken lung function. When you have asthma and you smoke, your lungs will weaken more rapidly. Smoking around children with asthma will weaken their lung function, too.
