Check into how much of your health insurance and/or tax dollars goes into providing health care for folks who can't afford to pay the bill. Even here in MA, where everyone is required to have health insurance, some folks still subsidize others, and so the costs of bad choices made are imposed on others -- they are not borne solely by the person making those bad choices.

Don't speak for everyone. The reality is that some people are affected by cost. Taxes on cigarettes have saved at least one life. And saving just one life is worth whatever negative aspects you could possibly be ascribing to the imposition of the taxes. Unless you value life so little, of course.
