Global experts are also almost unanimous in their findings about climate change, but it hasn't really had an impact on US government policy, though. Maybe in more socially enlightened countries these nicotine conclusions will have a substantial effect, but I wouldn't hold my breath about change coming here in the very near future.
You really have to follow the money, especially in this country. I can't see any way that a nicotine mandate will be passed, but our VLN ciggies should be allowed to compete on the open market. Maybe something like tax incentives for BT entities to produce their own VLN products, using XXII IP of course, will help move the agenda along.
