The real issue here, and the problem, as I see it, is not one of administration of e-cigs as either a tobacco or drug to be regulated. It is one of commerciality in your country. If the heads and hearts of the law makers in the US is in the right place they will actively seek to conduct experiments to determine the trade off between the health benefits and risks associated with e-cigs and make decisions involving its regulation accordingly. In the end, if they do that, they will realise that more people will die from the regulation of the e-cig market than will be saved. If their impetus is money ie, the transfer of the industry from the public and small business, to big tobacco and big pharmacy, then it won't matter what common sense and reason and formal study about e-cigs reveals, or what is in the best interests of the health of its citizens.
I agree whole heartly... I will point out, however, that the USA isn't the only place dealing with this issue either... The same issue is being brought up in a lot of places as another example being with the European countries also dealing with this as much as we are. What I think that is important to do as individuals is to make certain that our voices and concerns are heard so that those others that are more interested in their profit margin or other agendas don't win the battle in this ( or other important ) issue.
