There's Hope for the Statists (Tobacco-Control Edition)
According to a speculation at Velvet Glove, Iron Fist, major reason for the opposition to the e-cigarettes is that it interferes with the use of tobacco control as an excuse to extend State power. On the other hand, there's hope for the statists yet. They can always call for government-subsidized e-cigarettes. If anybody objects, accuse them of starting a “war on tobacco users.” Look for them to quote mine pro-tobacco libertarian rhetoric in support of the idea.
There's another side to subsidies: If there turns out to be a problem with e-cigarettes, no matter how small, the subsidies can be used as an excuse to regulate. There may even be a law that the waste from subsidized e-cigarettes can only be be disposed of in a repository in Nevada that the authorities can order closed.
