I fully agree about government's reluctance to back out of regulation. However, I believe the FDA has a real concern with how they should propose regulation here. They made their stance once and got spanked in court. They didn't get away with regulating them as pharma products. They don't have a lot of science to use as a defense if they end up in court over proposed regulation. The "We just don't know" defense won't work. The "What about the children" defense won't work. They need some science to bring to the courtroom and there's very little that supports any strong stance against e cigs.
I believe they realize they have a dilemma in that their opponent was very weak financially the first time around, but there's a lot more ammunition available now. It will be interesting to see how they try to resolve this.
That may be exactly what their lawyers are thinking... excellent points.
And there may be someone there (doubtful.. but perhaps) who is thinking... ecigs may* reduce lung cancer more than the decades of work by the American Cancer Society and the medical profession combined!
*one can use 'may' when it's positive
but they get regulations passed which kill jobs, and save no one. Then they run for city council.
