As I understand it vaping is different for everyone. My experience is great. I smoked for 42 years (and heavy). I have tried quitting many times and tried EVERYTHING(patches, gum, hypnosis,pills and anything you can think of). From the moment that I picked up my 510 for the first time I knew that this was it. For 3 weeks now I haven't even wanted an anolog and that is a first for me. My son and wife also started vaping at the same time and we all agree that there is no reason to ever buy another pack.....BTW I sent an email to the Canadian Cancer Society and asked their opinion. they said" that they have not tested them and referred my to the FDA and Canada health websites BUT her PERSONAL opinion was that if this is what it takes for me to quit then do it
Good luck and enjoy
