You know, a lot of folks are pointing fingers at Glaxo and the other "smoking cessation" product manufacturers, but frankly, I think it goes WAY beyond that. I think the real culprits are RJR Reynolds, US tobacco, Philip Morris etc. Those fat cats are crapping their pants over the e-cig revolution, and they've got the money to buy Senators, Congressmen, and the FDA.
The FDA is a wholly-owned subsidiary of Big Pharma, and they are the ones ignoring the law and the courts to try and destroy the e-cig market in the USA. I think Big tobacco is just sitting on the sidelines hoping this all drags out until the Chinese patents expire. Big Tobacco can then jump in and use their lobbying power to push Congress to make it all 100% legal and take over the USA market.
