    Well all I can say that after 9 months of vaping, my heart rate has improved..from 120/80 to 110/70. That's a tangible data... Others like I can do better exercises, can climb stairs without choking are u can say my personal intangible findings... yes I did suffer from lung infection after one month of vaping. Vaping could be a reason so the air around me or some other things could also be responsible...I and u may never know... in the end I'm living a better and healthier life than my 1 and 1/2 a pack/ day smoking days
