Should universities prohibit college students from smoking?

My friend, it's my pleasure to answer your question.

In my opinion, in universities, I don't advise teachers and students to smoke on campus, especially in public places and crowded places.

First of all, cigarettes are harmful to your health.

When cigarettes are burned, more than 4,000 compounds will be released, which will affect smokers themselves and endanger the health of respiratory system, nervous system, reproductive system and other organs.

1, respiratory system: the compounds burned by cigarettes will directly affect the lungs through inhalation. Continuous chemical stimulation caused by long-term smoking will change the normal structure and function of the lungs, leading to chronic obstructive pulmonary disease, chronic bronchitis, emphysema and other diseases. At the same time, smoking will shorten the cilia used to protect the airway in the bronchus, reduce the defense ability of the bronchus to the outside world, and make it more prone to various respiratory inflammations. At the same time, smoking will significantly increase the incidence of lung cancer. Among lung cancer patients, more than 70% have long-term active smoking history. In addition to lung cancer, modern medical research has also proved that cancers such as oral cancer, throat cancer, esophageal cancer and pancreatic cancer are all related to smoking.

2. Nervous system: Smoking will lead to the decrease of cerebral circulation blood flow and blood oxygen content, leading to cerebral vasospasm occlusion or bleeding, which will lead to stroke, mental decline, paralysis and other diseases. It will also accelerate cerebral arteriosclerosis and lead to stroke.

3, digestive system: smoking will stimulate the digestive system, leading to excessive secretion of saliva and gastric juice, aggravating the original gastrointestinal diseases, making it difficult to heal digestive tract ulcers. At the same time, nicotine in cigarettes can also stimulate the contraction of gastrointestinal mucosa and reduce appetite. In addition to gastrointestinal tract, smoking will also affect the normal metabolism of lipids in the liver, which will increase the cholesterol in the blood. On the contrary, it will increase the burden on the liver, form a vicious circle, affect the lipid metabolism of the whole body, and lead to the increase of blood lipids.

4. Blood circulation system: A large number of free radicals and oxidizing substances in cigarettes not only reduce the oxygen content in blood and increase blood lipids, but also consume the original antioxidant substances in the body, resulting in the accumulation of oxidizing substances and free radicals in the body, leading to thickening of blood vessel walls, which is more prone to coronary heart disease.

5. Exercise system: Smoking will lead to vasoconstriction, affect the local blood flow of bones, significantly prolong the regeneration time of broken bones, and also lead to joint aging and degenerative osteoarthritis. In addition, smoking will also affect the loss of calcium in bones, which is more prone to osteoporosis and fractures.

6, reproductive system: smoking will inhibit the excitement of the nerve center, leading to a decline in male sexual desire, while vasoconstriction caused by smoking will also lead to poor peripheral circulation and cause impotence. The compounds in cigarettes can significantly affect the quality of male sperm, leading to an increase in abnormal sperm or a decrease in sperm activity. For women, smoking will interfere with the normal secretion of estrogen, and for pregnant women, smoking will also lead to fetal malformation.

Secondly, second-hand smoke can harm the health of others.

When smokers themselves are hurt, people who are forced to accept second-hand smoke around them are also dangerous. Second-hand smoke refers to passive smoking, which has many hazards, including respiratory system, cardiovascular system, pregnant women and children.

Respiratory system: Secondhand smoke will produce a lot of harmful gases, such as nicotine, carbon monoxide, coal tar, nitric oxide and so on. These harmful gases will cause certain damage to respiratory mucosa, thus increasing the occurrence of various respiratory diseases such as bronchitis, bronchial asthma, pneumonia and lung cancer.

Cardiovascular system: Smog will lead to vascular sclerosis and cerebrovascular diseases, and have adverse effects on diseases such as insufficient blood supply to the brain and cerebral infarction. Will increase the risk of coronary heart disease.

Pregnant women: Secondhand smoke may have serious adverse effects on pregnant women, including abnormal embryonic development, abortion, premature delivery, ectopic pregnancy and so on.

Children: Secondhand smoke is also the main cause of children's asthma, which is easy to cause children's asthma, tracheitis, pneumonia, ear diseases and so on.

Furthermore, the Ministry of Education has clearly and strictly restricted smoking in colleges and universities!

Notice from the Ministry of Education, excerpted from People's Daily Online.

Smoking is prohibited in all university buildings, and smoking rooms are not allowed. No-smoking signs and school no-smoking supervision telephones should be set up in eye-catching positions. A small number of smoking areas can be set up in outdoor open-air areas according to the actual situation, and obvious guiding signs and warning signs such as "smoking is harmful to health" can be set up. The setting of smoking area should meet the requirements of fire control, and be far away from places where teachers and students are concentrated and necessary passages. Conditional schools should install smoke alarms, video equipment and other devices to strengthen the monitoring of smoking and prevent people from smoking in relatively independent offices or laboratories. Take effective measures to encourage and guide teachers and students who have smoking habits to quit smoking.

Finally, I think if you really can't help smoking, you should stay away from crowds, empty places or smoking rooms. I also hope that smokers will cherish the health of themselves and others.
