I'm with the same problem, I don't have asthma, but allergy, and cigarettes are not very good for me either, but they are my best friend in new situations and among new people especially. We have a law now that forbids smoking in closed areas, coffe shops and bars as well, but we're lucky to live in such nice climate that we can sit in the outside terraces through the whole winter. Have you ever tried quitting cigarettes?
