Smoking makes the airways become swollen, narrow, and filled with sticky mucus — the same problems that cause breathing trouble in people with asthma. For this reason, a smoker who has asthma is more likely to have more frequent and severe flare-ups.
If you have asthma, smoking is especially risky because of the damage it does to the lungs. Smoke irritates the airways, making them swollen, narrow, and filled with sticky mucus — the same things that happen during an asthma flare-up. That's why smoking can cause asthma flare-ups (or "attacks") to happen more often.
