How do I get my parents to stop smoking?

My parents have smoked for years. I have asthma and I a brother 3 years. My parents try not to smoke around us and used for smoking outside our fireplace in winter. But now, we just moved into a new house, and no fire so that only smoke in the house. Who can not afford to stop using these programs, smoking and purchasing 3 times a day does not. They are really wonderful people, but smoking's not really a good influence on other esapecially my brother and me How can I stop smoking?

When I was a kid I used to throw my parents' cigarettes in the toilet. They both eventually resigned. : D true story.
