Smoking is good for you

Ok.  It's an incendiary title.  But Seth Roberts is writing good stuff about the topic, and links to some fabulous stuff.  Remember prior posts of mine that linked to Scott Sumner on smoking econ, and Robin Hanson has a whole series.

If anything else, please remember this when someone says "The science is settled".  Unambiguous settled science usually means someone wants to convince you do something you don't want to do, and they've done more research than you.
