• Once a state makes "sin taxes" a significant part of its revenue stream, it has an incentive to keep people smoking and drinking. If everyone quits smoking, the state does not get any cigarette tax revenue. Is it really a good idea to fund public services on the back of citizens' addictions? Do you think cigarettes should be outlawed, taxed heavily, or left for market forces to decide? Should "sin taxes" be added to sugary sodas and other fatty foods?
