give em an inch...pretty soon you will be paying more than half your income in taxes, it will be illegal to have a cigarette before you are 18, or a drink before you are 21, or to not wear your seatblet..O WAIT!
Course considering how greedy the government is getting for more and more tax money from us, they'll probably start encouraging more and more people to smoke ("uh, we were wrong about cigarettes causing cancer"). And then increase the cigarette tax.
Shoot, they may even let TV show cigarette commercials again.
Y'all know I'm making fun, but nothing the government will do anymore surprises me.
