How to convince someone to quit smoking?

Its driving my absolutely crazy, my dad smokes non-stop everyday, on the balcony and I can frequently smell it… I’ve been trying to persuade him to quit for years, but he never does. The subject of smoking always ends up in a heated argument and it really starts to affect the relationship a lot.

Plus the cigarettes cost a lot due to laws and it really gets on my nerves because its a waste of money. I really am concerned that I have been exposed one time to many, I have to eat dinner a lot and the guests smoke so much that I am concerned about getting illnesses from second hand smoke…
