Cigarette Smoke Induces My Asthma

Cigarette smoke is aan irritant that always induces asthma attacks for me. I try to avoid it, but it's difficult living where I do. My biggest problem is I can't go to restaurants or bars (I'm 26) with friends or co-workers because all the local places allow smoking. There are weekly get-togethers for my office at a nearby sports bar and I'm always left out. Consequently, I find it hard to make friends or go out anywhere, since I've run into smokers lighting up right outside places like the shopping mall.

I am wondering if anyone has any advice on how I can stop being so sensitive to smoke. I take Singulair and am able to run, cycle, and other various activities with no problems.
