I smoked over a pack a day for around 30 years or longer. I never thought I could get off them and when electric cigs came, I was so proud of I stopped at last. It has been a year now and I use 11 mg. oil the e-smart kanger. I love it. I feel at least i am not getting all the junk put in in real cigs. I just like my electric cig now. I think they are the best thing that ever happen for us smokers or ex- smokers to have another way to help us. Even if we stick with just e-cigs it is better then all the smoke in our lungs. Everyone is so happy for me and now no more being rude and blowing smoke in faces. I feel thankful for electric cigs. I have a dementia mother and allot of stress or I may of been off even the electic ones. I have heard it takes a while. I really enjoy my e-cig and don’t worry about it.
