Senior three topic composition: Smoking is harmful to teenagers' health.

Tobacco is considered as one of the most serious social problems in the world. At present, the number of smokers in the world has reached 65.438+0.2 billion, and about 3 million people die of diseases caused by smoking every year. There are 350 million smokers in China, among which the smoking rate of minors is increasing year by year. According to the sampling survey made by the health department in recent years, it is found that the smoking rate among college, high school and junior high school boys is as high as 46%, 45% and 34% respectively, and the situation is extremely grim.

Parents have the responsibility to care about their children's health, stop their bad behavior and actively guide their children's healthy growth. Studies have proved that children under 10 are generally disgusted with smoking and think that smoking is suffocating and unpleasant. 1 1- 13-year-old children are gradually curious about smoking and eager to try. 15, they began to regard smoking as a "sign" of their growth. This shows this. 38860 . 6868686866 1

Parents and teachers should first do not smoke themselves. If they have a smoking hobby, they should quit smoking and set an example for their children. And it is necessary to explain the harm of smoking to children and let them know what is behavioral beauty, because this period is a crucial period for children to develop good behavior habits. Many countries in the world pay attention to anti-smoking education for teenagers when formulating smoking intervention plans. China has also formulated a policy of "controlling smoking-starting with teenagers", because reducing the smoking rate of teenagers means reducing the smoking rate of adults in the future.

Many countries in the world have passed legislation to prohibit the sale of cigarettes to minors under the age of 18, otherwise the seller will be fined heavily. Article 15 of China's Law on the Prevention of Juvenile Delinquency clearly stipulates that parents or other guardians of minors and schools should educate minors not to smoke. No business place may sell cigarettes to minors.

Smoking is very harmful to the health of developing teenagers, and has a certain degree of influence on bone development, nervous system, respiratory system and reproductive system. Because of the imperfect development, imperfect function and weak resistance of various organs in adolescence, the harm of smoking is even greater than that of adults. In addition, because the respiratory tract of teenagers is narrower than that of adults, and the cilia of respiratory mucosa are underdeveloped, smoking will damage the respiratory tract and produce inflammation, increase the resistance of breathing, reduce vital capacity, and affect the development of teenagers' thorax, thus affecting their all-round development.

A large amount of nicotine contained in tobacco is also toxic to the brain, which will reduce students' memory, listlessness and academic performance. The survey found that the academic performance of smokers was lower than that of non-smokers In addition, teenagers are in a critical period of sexual development, and smoking reduces testosterone secretion by 20%-30%, leading to sperm reduction and deformity; Girls have delayed menarche and menstrual disorders. Smoking among teenagers will also advance the onset age of coronary heart disease, hypertension and tumors. Relevant data show that the younger you smoke, the more serious the harm to your health. /kloc-The mortality rate of smokers who started smoking at the age of 0/5 is 55% higher than that of smokers who started smoking after the age of 25, and it is 1 times higher than that of non-smokers.

The above-mentioned experts' research, investigation and appeal on the health hazards of smoking to teenagers are not sensational. A story about a 16-year-old boy suffering from cancer due to smoking is a profound example:

From 65438 to 0998, the Department of Thoracic Surgery and Anesthesiology of Cancer Hospital of China Academy of Medical Sciences joined hands to take out the tumor for a teenager in time and successfully reconstruct the carina. The carina is the "communicating artery" where the trachea and the left and right bronchi breathe, and it must be kept unobstructed. Bi Mou, a middle school student aged 0/6 in a city in the south, has a tumor on the carina. Half a year ago, he developed symptoms, but unfortunately he was misdiagnosed by the local hospital and has been treated as a cold. After careful examination, the doctors of thoracic surgery and anesthesiology in Cancer Hospital of China Academy of Medical Sciences found that the tumor had blocked the patient's left bronchus, leaving only a small gap in the right bronchus. The operation is very difficult, especially anesthesia to ensure the safety of the operation. Although the cancer hospital has done dozens of medical breast augmentation operations and has a lot of experience in anesthesia for such operations, after all, the patients are young, the tumor is large, the condition is serious and the operation risk is high. If the operation is not done in time, the child will soon suffocate. Doctors' well-designed treatment scheme and skilled medical technology have given teenagers a new life.

How can a young middle school student get such a fatal disease? It turns out that he is a smoker and has been smoking for more than two years, from stealing to smoking in public until he needs to smoke three cigarettes a month. According to oncologists, when smoking, most of the smoke enters the lungs through the trachea and bronchus, and a small part enters the digestive tract with saliva. Some harmful substances in smoke remain in the lungs, and some enter the blood circulation and flow to the whole body. Under the synergistic effect of carcinogens and cancer promoters, normal cells are damaged and become cancer cells. The younger you are, the more sensitive human cells are to carcinogens, and the greater the harm of smoking. The reason why this teenager suffers from cancer is the synergistic effect of his premature, excessive smoking and other cancer-promoting factors. Now, he not only says that he will never smoke again, but also intends to persuade his classmates and friends to give up smoking as soon as possible.

In order to make us live healthily in a beautiful environment without smoke and fog, here, we provide 10 tips for parents to educate their children not to smoke. I hope it will be beneficial when you strengthen this education:

1, let children know what you think of smoking. Children have the right to know what to do and what not to do. If you don't tell them, they won't know the code of conduct.

I believe that children will listen to their parents' opinions. Maybe some children will resist at first, but when it comes to making decisions about risky behavior, they will attach importance to and make use of their parents' correct opinions.

Don't think that it is enough for school to educate children not to smoke. Although children will hear the message that smoking is harmful to health, they may think that they may not really be affected by it.

4. move with emotion. Tell your child that if he continues to smoke, you will feel very painful and disappointed, which may be more effective than talking to him about the health hazards of smoking.

Children may use the atmosphere formed among peers as an excuse to smoke. We should not only pay attention to this reason, but also help children realize that they are responsible for their actions.

6. Set a good example. If you smoke, you should put aside your feelings about cigarettes and make it clear that you don't want your children to smoke.

7. If relatives smoke, tell them not to give cigarettes to their children.

8. Don't think that smoking is not as dangerous as other risky behaviors. Many studies have found that smoking often leads to health and social problems quickly. If children start smoking in their teens, they will generally be addicted to smoking for 20 years.

9. Try to keep cigarettes away from children's living environment. If the community store sells cigarettes to children, it should improve *.

10. It is never too early or too late to intervene. Children aged 7-9 who smoke for the first time or have smoked for several years can also quit smoking with the help of adults.
