I'm a bit hesitant to suggest it, but how about a consumer pledge not to buy from suppliers who make unsubstantiated health claims?
I agree 100%! I also believe we should treat e-cigs the same way we do analogs. At this point we (the users) can not prove these are safe for us or other people. Please people, don't go walking into your local grocery store vaping away causing trouble and then telling everyone how safe the e-cigs are.
