Dear Annie: I am a nonsmoker who has asthma and early heart disease. When I am at family events and outdoor concerts or entering stores and public places, I often find myself exposed to secondhand smoke from cigarettes and cigars. Even though I make every attempt to avoid this smoke, it is sometimes impossible. This results in my having burning eyes, difficulty breathing, a wet cough, etc. At times, I've needed oral and inhaled steroids because the inflammation was so severe.
