Smoking and asthma...

It is NOT advisable to smoke. Smoking will kill you.

Smoking if you have asthma is a very bad idea.

As is common with respiratory disease, smoking adversely affects asthmatics in several ways. Asthma symptoms in smokers tend to be worse, and lung function tends to decline more quickly. Drugs for asthma tend to be less effective for people who smoke. Asthmatics who smoke typically require additional medications to help control their disease.

Furthermore, exposure of both nonsmokers and smokers to secondhand smoke is detrimental, resulting in more severe asthma, more emergency room visits, and more asthma-related hospital admissions. Smoking cessation and avoidance of those who smoke is strongly encouraged in asthmatics.
