My husband I both have smoked for many years, we both tried the ecigarette that has changed our smoking habits drastically. I smoked 1 to 1 1/2 packs a day my husband 3 to 3 1/2 packs a day. I started with 18 mg of nicotine and in 2 months went down to 0 nicotine. I kept using the ecigarette because i did not replace my habit with eating like in the past to gain a huge amount of weight. My husband uses 24 mg nicotine and he has been completely smoke free for going on 4 months. I have slipped a couple of times during some stressful times. Our house, and cloths are clean smelling. We both started using the ecigarette mostly due to the cost of smoking cigarettes had gotten totally out of hand.
