I remember my doctor, also a two pack a day smoker, lecturing me in my early twenties as he blew his brains off. My former fiancee, a pack a day smoker had a stroke, and when he asked me if he was smoking again I said we were
vaping. So in his diagnostic for the stroke put "flight stroke". My doctor knows little about it and was unsympathetic about it. I haven't been in yet, we'll see. The one that doesn't like it is my neumonologyst because I'm alergic to something in the juices I'm using. Strange, but I don't cough when I smoke but I do cough when I
vape.
