I think you are under the mistaken impression that the Lung Assoc. (and all the others) actually care about us. No, they do not want to see us go back to smoking. They are of the "quit or die" mentality.
In actuality, the longer we do smoke, the more funding they get to get us to quit, but the longer we smoke, the more funding.... viscous circle - all to benefit them. It's not about us, the public health or any other noble cause. Its about the money and the fact "they" don't want to see anyone put their hand to their mouth and exhale anything that looks like it might be smoke. "THINK OF THE CHILDREN!!!!" LMAO!
Oh, except for medical ......... - that's ok as long as they don't have to see it being consumed.
It's not just the FDA, the "Associations For Our Own Good" etc. its everywhere in government. I'm dealing with it now with Calif. Air Resource Board. On some of those forums you could literally switch the topic from diesel to E-cigs and the posts are the same - almost verbatim. Good thing Halloween is coming - It's getting Scarrrrrry out there!
