I am hoping they leave things alone, but what I really fear is that they really are just looking for a way to make up for the lost tax dollars they would be getting from us as smokers.
And contrary to popular belief, they do NOT use those tax dollars strictly for smoking cessation or paying for the ills smoking causes on our society.
When I lived in Arkansas, they used the fact that smokers where a minority to get a tax on cigarettes to build a new trauma unit. They used a tax that only effects a small percentage to benefit the whole population. But since most folks were unaffected, they felt fine with adding $1.00 a pack tax to us poor saps that are addicted to them.
In reality, they should see it for what it is, the most effective stop smoking aid available. I am not dis-illusioned and do think that eventually, they will find that vaping cause some health effects.
But the only government that has done any real scintific research to my knowledge is Australia. Their finding, "we can't say it is safe because there is no long term studies done, but it is definitely safer than cigarettes."
