I can't think of much about the ritual of smoking that vaping doesn't replace. Well, there is actually lighting the cigarette, flicking the ashes, trying to remove the dropped ashes from your clothes without leaving the grey streak, emptying your ashtrays, wiping your eyes when you get smoke and ashes in them, cursing yourself when you leave a ciggy burn in your clothes or upholstery, spraying on the odor cover on yourself or in the space, coughing up loogies inside and trying to find a good spot to spit them out, and the late night trips to the gas station to buy more cigs. OK, so I guess there is a lot that vaping doesn't replace, but nothing at all that I really miss and find the need to replace.
But as far as the motions of the arms, something in your hands, the throat/lung hits, the vapor visuals, the taste (although the smoke taste can't fully be duplicated, but is replaced with something much better), and all the rituals to which most of us are really addicted, vaping does a most excellent job of providing it. You will likely agree once you try it. And if there's something you still feel is missing, let us know and we'll find a way through it. We all wish you the best.
