Where think of the children == reducing incidence of lifetime addiction and horrible disease. Though I guess you have to pick your priorities.

I'm fine with that. Cost was a factor in helping me quit. Considering the lifetime cost of being a smoker (both in past expenditure and probable future medical expenses) I wish cigarettes had been much less affordable when my parents were puffing away during my childhood. I loathed cigarettes and yet I was in a hurry to try them and sure enough became seriously addicted to tobacco.

This is actually being discussed by some politicians, and some are past the discussing step AFAIR.

You forget that a sugar tax is increasingly popular in progressive circles.
