On a lark, I sent a note to Rep. Tina Liebling to ask if she was aware of any rumblings of legislative interest in e-cigarettes...I haven't read much about legislators elsewhere getting energized, and I haven't pursued this further, but here's what Liebling said by email:
I am working with the anti-smoking community to see if changes are warranted. My counterpart in the Senate is also having those discussions. The Commissioner of the Department of Health is concerned about the issue, too, so his department may have a proposal.
I don't want to overreact, because I haven't seen evidence that the e-cigs are harmful to adults--and it's easy to believe that for those who already are addicted to nicotine they are less harmful than cigarettes. However, I am concerned that if people get used to "vaping" in places where they can't smoke, and if we allow e-cigarettes to be promoted with the idea that they are safe (and in exciting flavors), a new generation of young people may get addicted to nicotine in very short order.
Bottom line: it's on my radar, but I'm not sure yet whether I will be introduce legislation on it next session or what that would look like.
