My brother smokes a pack of cigarettes almost every day on average. How can I discipline him as a sister?

I remember when I was a child, someone asked me, do you know the benefits of smoking? I said I don't know. He said smoking has three advantages. 1, thieves dare not enter the house at midnight. 2. Mosquitoes and flies don't bite when going to the toilet. 3. The dog saw it and ran away. I asked why, and he said, I smoke too much and cough. When the thief came, he thought you were awake, so of course he didn't dare to come in. Smoking a cigarette when you go to the toilet can smoke away mosquitoes and flies. If you smoke too much, you will hunch over and the dog will think you are looking for something to throw at it. I remember someone telling me the benefits of smoking. It's about an old man who likes smoking. Naturally, he spent a lot of money. The old lady can't read or keep accounts. How much does the old man spend on cigarettes, the old lady puts it in a box. By the end of the year, the old lady took out all the money in the box to educate the old man and let him know that it will cost a lot of money in a year. Boy, I really don't know how much I can spend. I think I will never smoke again. As a result, this year. The old man thought it would be better to celebrate the New Year this year, so he asked the old lady to take out the money for the New Year. The old lady said, you didn't smoke, didn't spend money, and I didn't put it in the box. Not a penny. As a result, after the poor year this year, the old man's old illness recurred. I'm just kidding. I think it's funny. Laugh at yourself. Do not advocate smoking. [put away]
