Zcat's comment: The states sure did cross the line. They want to balance their budgets on the backs of the smokers, yet they say they want Smoke Free Everything! They sure aren't getting both! Right on the money.
Problem is: These politicians continue to fund their addictive habit of spending via taxing people's addictive behavior. As people modify their behavior as a result of the taxation, our tax-money addicts will need to go on a methadone program. Or not. You already see it as attorneys and states greedily eyeball the casino and fast food industries.
