Any cure for asthma?

No: True Asthma is a condition with a wide range in intensity, often based on inherited factors, that is like eye color or stature.If you have it you must learn to manage it. Kids often wheeze with infections and this may not be true asthma, with many never wheezing after age 4-5. We have enough treatment options that you can treat and remain symptom free for years, but the tendency will remain.

If asthma is caused: by an environmental exposure (respiratory irritants including tobacco smoke), it may be "cured" by eliminating that exposure. Sometimes it goes away on its own. Sometimes it occurs only intermittently. Usually, however, in adults, it's a treatable but not curable condition.
