The only legal recourse is to lobby your representative to prepare and submit legislation to reverse or exempt that which makes electronic cigarettes illegal. Compared to the counter lobby, we don't stand a chance.
None of that can be done until a ruling is made and all appeals have either been exhausted or the case has been dropped. I'm not a lawyer but I'm not clueless either.
I made no mention of any legal recourse, but of an enforcement resolution that would, ideally, balance the need for the rule of law with whatever can be construed as being our collective legitimate interests. This could be something as simple and reasonable as lobbying the FDA to engage in a staged or delayed enforcement strategy (while tobacco-based ecig replacement products get developed), or something as far-reaching and bold as arguing for the FDA to construe the FSPTCA in such a manner as to allow for at least some nicotinated non-tobacco products to be regulated as tobacco products.
I don't think that you are clueless either, even though you have struggled with acknowledging the fact that you inappropriately attributed a defeatist attitude to someone who was not exhibiting one.
