Needless to say, the health hazards of smoking and drinking are sometimes gloomy, indulgent and harmful to society. At present, many public places have stipulated that smoking is prohibited, and university campuses, as academic research places, should ban smoking and alcohol. First of all, the university campus, whether it is facilities or students' manners, is a reflection of university culture. Not to mention how university culture embodies scientific spirit and humanistic spirit, at least it should be positive and healthy in its cultural atmosphere. The strong smell of alcohol will also destroy the learning environment and learning atmosphere. But the research environment is directly related to the development of schools and students. Moreover, universities, as institutions of higher education, have the responsibility of demonstrating and leading the whole society. Smoking ban on university campuses will set an example for the whole society. If high school students smoke and drink too much, how can the awareness of smoking ban be deeply rooted in people's hearts? Starting from students' living habits and growth process, it is an objective constraint to prohibit adults from drinking and smoking and to drink free of charge for students who live in school for a long time, which is the key to cultivate good habits. In order to realize the ban on smoking in university campus, education and system should be mastered. We should strengthen the health hazards of tobacco and the popularization of knowledge, deeply understand and strengthen self-restraint, but it will also lead to greater pressure of public opinion supervision and form a wide environment. In this system, firstly, smoking ban should be written into campus norms, and then commercial shops should be prohibited from selling tobacco on campus. In addition, supervision should be strengthened and the corresponding punishment system should be implemented. Banning smoking in university campus does not deprive students of the right to choose their own lifestyle freely, but emphasizes the macro environment of university campus. Campus culture is to create a more harmonious and excellent academic environment. Correctly guide the social atmosphere, but also focus on it, and guide students to develop healthy living habits!
