I wouldn't base an opinion on those reports, and much of it probably depends on how much they nickel and dime each group, but I think, on balance, the evidence suggests that there's not an enormous difference in cost to society.  If anything, smokers and the obese may be a little cheaper.

The rest I agree with you on, although, really, I can't personally claim to be innocent in the "consume lots" department.  I'm sure I consume more than I should.
