I smoked cigarettes for 24 years. At least a pack to 2 packs a day. Upon receiving my e cigs I have completely quit smoking without any problems or urges to smoke. I started with cig a likes for a week. Then moved to a ego style wich I am currently still using. I am now beginning to start using MODS. I vape approximately 3 to 5 ml of 18 mg juice a day. I never thought that quitting cigarettes would be this easy. I would encourage any smoker that wanted to quit to try vaping.
