In any decent system, the patient should be explained the risks, and if he chooses to go on, it should be his right to go on.
I disagree; but I'd be repeating myself to say much more.
Do note that the UK has recently [link|http://news.bbc.co.uk/2/hi/uk_news/politics/4709258.stm|banned smoking] in public enclosed places and private clubs. For medical reasons. In Scotland, where the ban was imposed last year, [link|http://news.scotsman.com/health.cfm?id=1451402007|heart attacks have dropped by 17%-20%]. It's not unreasonable to require that a surgery patient quit smoking before he gets a place in the queue. They're not refusing to treat his pain.
Cheers,
Scott.
