we quit smoking the very time that the system was showed to us. my wife immediately went to 0 nic. I run around 6 nic we both smoked over 35 years.i would really hate to see any authority mess with the system a lot because it totally got us off smoking right away as far as where it can be done, doesn’t concern me a lot I was already used to smoking rules just don’t take the privilage from me because you don’t understand it…just a note from us…when you drive by a factory and see smoke…just because it looks like smoke doesn’t mean it is smoke…they say where theres smoke theres fire. lets grow up and try to understand what we see..the system is great and a great alternative to something I was going to do all my life…SMOKE!!! not anymore..unless someone with enough power takes it away…that’s my logic…spock out..sincerely john Walton tn.
