Not even remotely!
E-cigs are a harm minimisation product, something that is a low harm alternative to a very addictive drug.
It is thus like methadone. No one would have a problem morally with taxing "junk" if it were legal, but taxing methadone would be actively encouraging use of "junk". Thats a morally quite difficult to defend position, and would create a crap storm.
Taxing booze and cigs is okay, because their presence as products creates measurable harm to society and individuals. E-cigs by comparison, remove existing harm from society. Even if it weren't for tobacco's popularity, e-cigs are basically equivilant to caffiene.
I personally do not see how you think these things are equivilant. You must at least be able to see that taxing a low harm alternative, actively encourages smoking, no?
If anything e-cigs should be _subsidized_.
And any government organisation, that is seen to be actively encouraging smoking, should to be prepared for some serious backlash IMO!
(That wont stop them from doing stupid things sometimes, but if any of these regulations go the wrong way, either in the US, or the EU, there will be a loud and definitive opposition voiced - there can't not be when, regardless of intention, a bad law will be causing tobacco smoking numbers to rise)
Never try and apply logic to US political issues.
We are a nation largely of ...... and having a representative government, we are nearly perfectly represented.
The only thing these people want, care about, or respect is money and they will do whatever is required to get as much of it as they can.
