I bought a evic in the hope I would quit smoking, great success! It has been a week and I have no desire to smoke a cig ever again. I've been smoking 2 1/2 packs a day for 15 years. Yesterday I smoked a cig and could not stand the taste, I threw it out after a couple of puffs. I'm happy to say I don't ever want another cig for the rest of my life.
