Reasons not to be worried:
Crack pipes can be bought in convenient stores (usually in poor neighborhoods) containing a rose inside the pipe (changing its use from a crack pipe to something you romantically give to your girlfriend/wife)
Bongs can be bought at head shops for use with smoking tobacco
N2O (laughing gas) can be bought in many places as whip cream canister refills
Vaporizers for smoking marijuana have been available forever marketed as Herbal Mineral Heaters (vaporbrothers, no links yet, google it)
Beer can be bought on ebay because the seller states they are selling the bottle and not in anyway shape or form responsible for the contents inside, the auction is for the bottle only.
Nicotine water is still available and they use no work around, its meant to be drank, they just have a simple "This is not FDA approved, does not cure any disease, etc" label like a bottle of Ginseng or Stress Tea usually contains. (nicotinewater, no links yet, google it)
If there is a ban, suppliers just have to find creative work arounds. The actual devices are simply batteries and heating electronics that have to be marketed in a different more creative way.
Nicotine is not illegal. Could we not just market the juice as flavored insecticide (kills the bugs and keep your plants smelling good) with labels saying this product is not meant to be inhaled, swallowed or digested. I know it is silly but really that is all it takes to bypass FDA laws a lot of times.
Alternatively you stores could sell flavor liquid (could be advertised to put into some special candle or something) and other places could sell 36mg unflavored nicotine as insecticide.
Really it just comes down to how the products present themselves if there is indeed a ban.
The thing that bugs me the most about a ban possibility is that e-smoking will become more of an under the radar thing as opposed to something that with no ban I could see a huge majority of smokers switching to over the next few years.
