So true. I was on 20 B&H a day for 15 years. Couldn’t swim a length of a pool without being out of breath. Admitted through ED in 2014 after a serious asthma attack. Turned to vaping once I was sent home. 9 Years later I look and feel much better. I can swim until my legs hurt now. I go running and rowing with no respiratory issues at all. My lungs have above average capacity and i never need my reliever inhaler. My asthma is almost totally absent.
