Question: Why does Obamacare single out smokers for higher insurance premiums, but not drug addicts, alcoholics, the obese, or risk takers?

Why should the health care system be used to subsidize obese people but tax smokers?  This just shows that politicians can't keep politics out of their decisions on how to run anything.  From Fox News:

Unlike drug addicts, alcoholics, or the obese -- all of whom represent higher-than-average medical costs -- smokers are the only such group with a pre-existing condition that ObamaCare penalizes. It allows insurance companies to charge smokers up to 50 percent more than non-smokers for an identical policy, depending on the state and any subsidies the person might qualify for.  

For example, premiums for a 64-year-old non-smoker, according to the Kaiser Health Calculator, cost $9,000 a year for a standard "silver" insurance plan.
The same policy for a smoker could cost $13,600. 

"I can't afford any insurance at that rate," smoker Don Hampson said. "I thought that was what ObamaCare was about, to stop all this." . . .
