I don't see how the FDA can do anything at all.
BT actually wants e-cigs, because they have to replace lost revenue from decreased smoking with another product. BP doesn't want e-cigs, because they steal market share from their established, albeit woefully inaedequte and potentially dangerous products. (I'll pass on the FDA irony about that topic for now.) And the longer and longer this plays out the longer and longer is the road of established use, no harm that the FDA has to acknowledge, even if they refuse to accept it. The FDA long missed their golden opportunity to "just say no" a long time ago.
