My father has a bad habit of smoking three packs of cigarettes at one go, which really disturbed me. I was worried about his health, as he coughed so often. I have tried to tell him to quit smoking, but have not mustered enough courage to go to him and tell him. So my friend suggested that I should convey my message and concern with the help of some smoking articles. Are there any effective smoking articles that I can keep on his desk, so that he can read those smoking articles when he finds the time?
