I understand your concern. But i dont think the lung function is lower due to using for a long time inhalers. If you have this situation you should see a pulmonologist to do a check-up for your lungs again by doing a SPIROMETRY with bdictators and a DCO test to. According to the results the specialist will decide your actual lung function. Wish you good health Chat Doctor.
