Great Dane is correct. Not only did the Congressonal Research Service, at the request of rabid anti-smoker Henry Waxman, determine that smokers pay far more into the system than they cost the system, even the New England Journal of Medicine said the same.
additionally the Master Settlement Agreement between the states and the tobacco companies was ossensibly to repay the states for "smoking related medical expenses" and that is paid 100% by smokers, not by the tobacco companies.
Smokers not only pay "their own damn bills," they pay the bills for a whole hell of a lot of nonsmokers as well. And they/we have since at least 1994 when taxes were a lot lower than now. The only way you can conclude that smokers cost society is to make the assumption that no one else ever gets sick, has an accident, or dies. You've been hornswoggled by the anti juggernaut.
In 1994, the nonpartisan Congressional Research Service spent 22 months and 20 million dollars--at the request of rabid anti Henry Waxman, no less--to determine just how much money smokers cost society.
Guess what: Smokers DO NOT COST SOCIETY. We pay in to the system far more than we ever take out. You should be paying US to smoke! The New England Journal of Medicine concurs, as do economists from Yale and Harvard, and the CRS reiterated that fact in 1999.
