This is an alternative to smoking cigarettes. This is a smoke free product. You will see a vapor like smoke only with no smell like tobacco smoke. You can even have a cigarette after dinner without leaving the table in a smoke free restaurant. This is an awesome product and is very easy to use. I has helped my husband to smoke less cigarettes with this product. Also, for you hunters out there, use this product for the edge of the deer not smelling you smoke. My husband uses this while sitting in his deer stand and does not have to be smoke free all day. You have to try it do believe it and this product is one of the best.
