We shouldn't victimize a class of people with additional "sin" taxes, such as the mayor's ill-advised idea to add $2 to the cost of a pack of cigarettes. That falls hardest on the poor, among whom smoking rates are the highest, and it is self-defeating. If high cost forces smokers to quit (a desirable goal) it also reduces the money that comes from taxing cigarettes. Pretty soon, we are back where we started.
