Thank You for Smoking by Christopher Buckley

Nick Naylor likes his job. In the neo-puritanical nineties, it's a challenge to defend the rights of smokers and a privilege to promote their liberty. Sure, it hurts a little when you're compared to Nazi war criminals, but Nick says he's just doing what it takes to pay the mortgage and put his son through Washington's elite private school St. Euthanasius. He can handle the pressure from the antismoking zealots, but he is less certain about his new boss, BR, who questions whether Nick is worth $150,000 a year to fight a losing war. Under pressure to produce results, Nick goes on a PR offensive. But his heightened notoriety makes him a target for someone who wants to prove just how hazardous smoking can be. If Nick isn't careful, he's going to be stubbed out.
