Not smoke it's vapour. There's literally no fire so no smoke. That said I don't think the laws need changed on it. Bad enough all the fumes you have little choice in breathing when you walk down the street so no need to force folk to breath in a gas that the long term effects are unknown. Fyi I use a vaporizer, it's defo helped get me off the fags and my lungs do feel better for it but I've never been under any illusion that it isn't harmful in some way and I will phase it out pretty soon. I do miss smoking though.
