I thought you guys were big "personal responsibility" aficianados? The state's interest is activated because the behavior amps up tremendous socio-economic costs. No one exists alone. All behavior is interrelated. Non-smokers pay extra to cover smokers, in a sense, as the cost is passed on. Smokers in the military should pay an extra "tax" on their health benefit. Thus only the persons engaged in the behavior assume the extra cost.
