Are there good ways to get a sick person to stop smoking?

Ask nicely: Spray saline into your nostrils frequently to flush out allergens and irritants. You will get the best care in a long term relationship with a provider who knows you over time. Discuss this with that provider.

Quit contract.: Smokers are very good at fooling themselves into smoking again. With a quit contract, the smoker has to answer to you, or to a group of friends, or to a group of people who are also trying to quit. Answering to others for one's indiscretions is difficult, and can help the quitter in his/her attempt.
