Respected Grandfather: I'm writing this letter to tell you that I hope you can pay attention to and support the anti-smoking policy. I know you're a heavy drinker, but I hope you can understand the dangers of smoking and make changes. Smoking causes many health problems. Smoking increases the risk of various diseases, including cancer, cardiovascular diseases, respiratory diseases, and so on. Smoking could also cause bad breath, yellow teeth, and poor skin, affecting one's image and quality of life. I know it's not easy to quit smoking, but I believe you have the ability to do so. You can try some ways to quit smoking, such as using Nicotine Gum, Nicotine Patches, Smoking Cessation Spray, etc. or seek professional help such as quitting smoking clinic or Nicotine replacement therapy. I hope that you can pay attention to your body and health and make decisions that are responsible for yourself. If you need any help, please do not hesitate to contact me at any time. I wish you good health and happiness. sincerely salute Your grandson/granddaughter
