But that's not the case fully. The US government (States and Local governments in particular) would be able to regulate vape products and place a sin tax on them as well. Do I think this is the right thing to do? No. Because I do truly think that vape products are used by adults to ease off the health issues when it comes to using cigarettes.
Government should have never become reliant on the taxes that they got from cigarettes and such, that's an issue in and of itself. They should be cutting their expenses in order to not have to rely on sin taxes, but they're not going to do that because government is government. They're going to spend more, complain about less taxes, ban things, tax more things, and so on.
But a boy can dream.
