I have smoked for 26 for years and tried cold turkey and nicotine patches to quit. In march of 2013 my boyfriend let me try one of his new ego T electronic cigarettes and I never gave it back. The electronic cigarette immediately replaced regular cigarettes for me and now several of my family members are using them too. I feel great and I will never go back to cigarettes. I started with a nicotine level of 24 and now I am down to 6. This is the best thing ever invented!
