I first started vaping with a smoke51. I know it only comes with the disposable carts with the atomizer built in and i've since switched to a 901 but the smoke 51 comes with a membership card which is the size of a credit card. on the back it says how the smoke is just a vapor and non carcigogenic, not subject to the smoking laws/bans, and asks that you be allowed to continue using it in their establishment and transport vehicles. I think every supplier should come out with these cards. if anybody gives you any problems you just pull out the card and show it to them.
