I smoked for 17 years until E-cigs. Havent smoked one since and ive tried everything to quit in the past and this is the only thing thats ever even come close to working. I owe in my future health. Its the best thing to happen to me in a long long time. Not only that I help my G-ma who has a lung condition and I wasnt able to even be around her for long periods because the scent of smoke on me bothered her so much, now I can help her like I need to be. Great way to switch to something better than the cancer sticks.
