on the topic of research-vs-prevention: for fuck's sake! It reminds me of how right-wingers used to say (and probably still do) that AIDS was God's way of punishing gays. Even if most lung cancer comes from smoking, there will always be a certain percentage that is caused by other things, including simply having to live in a nasty smog-infested environment. Prevention is important but cancer research is necessary too. And in some ways the argument is moot: it's not like lung cancer research is a completely separate endeavor from, say, breast cancer research. All cancer is related, and efforts towards eradicating and treating cancer benefit everyone.
