I’m a man aged 46 years old and I started smoking at the age of seventeen. When i was a smoker, I used to smoked not less than a box (of 20 pcs) daily. I started vaping since May, 2014 (until today) and 100% switched to vaping from the first day i bought my first e-cigg?. my personal and honest comment on the impact of vaping would be, it have improved my sense of smell, my appetite is back, no more tightness in the lungs and my stamina is better.
IMHO, switching to vaping was the best decision I’ve ever made.
