How do you know if you have C.O.P.D.? The reason I am asking is I stopped regular cigarettes last July and I don't cough or wheeze anymore but I find that I get short of breath easily. I went to a Doctor 2 months ago. Haven't been to a Doctor for a long time because as you all know when you smoke, whatever you have wrong gets blamed on smoking. I thought maybe I had a heart condition but blood pressure is great and ECG was good, took xrays and a cat scan and no lung cancer, so he says well you smoked for over 46 years so you have COPD and gives me a perscription for Spiriva, no change on the breathing that I can see and this is expensive stuff. I really love vaping and I see so many are saying their breathing is getting really good since making the switch. I don't think I have COPD any suggestions for my next Dr's visit
