11 Worst Cities for People with Asthma in America

7. Knoxville, TN

Knoxville, such a beautiful city. Well, unless it’s spring and you’re suffering from asthma or any allergies, that is. The high levels of tree and grass pollen have put the city on somewhat of a “black list” since these can cause asthma flare-ups, attacks and so on, depending on each. This results in a pretty high rate of asthma-related control meds being used, but also of quick relief meds related to this medical issue. There’s also the problem of there not being any clear anti-public-smoking laws in place.
