I was a smoker of cigarettes for 39 years and the last time I smoked I was up to 2 packs per day. I started vaping in Sept 2014 and immediately cut my smoking cigarettes down to 4 per day. Then within one month I stopped smoking cigarettes altogether. I continued to vape and gradually reduced my nicotine intake and now I do not vape with nicotine at all. How is this bad?
