I have severe asthma and allergies. I recently spent five days in ICU because I was exposed to second hand smoke when I was walking out of a sports arena. Why do smokers think they can light up as soon as they walk outside? We had parked on the third floor of the parking garage so we could take the sky walk and avoid going outside. When the event was over the security refused to let us use the sky walk. This completely surprised us so we just walked out the door. I have a Respro Aero Mask that I carry with me at all times. However I didn't have time to get it out of my purse before the security herded us and the crowd out the door. How do you deal with smokers outside public buildings? I carry a portable nebulizer, Albuterol inhaler and EpiPens with me at all times.
