technically there isn't much of a difference between smoking a water pipe and an analog. some might even say that smoking a water pipe is actually worse due to the inefficiency of water as a fliter as compared to the cotton bud analog types.
but then sisha got flavour mah, and it dun feel so harsh. last time i tried i could drag damn long and den be like puff the magic dragon
and yes i do have friends who sisha but do not smoke. i guess its e communal thing + the flavour that gives them a kick. the powers that be prolly took this as a yardstick and applied it to e-cigs as a whole. think they have an impression that this is a portable water pipe or something. hopefully they will dig a little further to find out that
vaping and using a water pipe are actually very different after you look past the initial similarities.
