1. Why are teenagers forbidden to smoke?
1. According to the statistics of the World Health Organization, one person dies of smoking-related diseases every eight seconds in the world, and nearly 5 million people die of smoking every year. This number is likely to double in the next 20 years. Smoking has become one of the most important causes of death in the world. China is a big tobacco country, and the current number of smokers is about 320 million. The government has done a lot of work to control smoking among minors and will continue to do so.
The United Nations Framework Convention on Tobacco Control was signed in June165438+1October 10 and will take effect on February 28th this year. However, an unavoidable fact is that in China, the smoking rate of minors is on the rise, and the age at which minors start smoking is on the decline. Every day, about 80,000 teenagers become long-term smokers. This situation not only affects the healthy growth of children, but also seriously affects the improvement of the overall physical quality of our country, so the problem of underage smoking has attracted more and more attention from the society.
2. Liuli, an associate professor of psychology at the School of Education of Shanxi University, believes that there are six reasons why minors smoke.
Psychological factors:
First, the pursuit of style and adult psychology.
Adolescence is a period of rapid growth of self-awareness. Almost from adolescence, many students feel that they are "adults". This strong sense of adulthood and independence makes them regard smoking as a sign of maturity and can't wait to pick up cigarettes to prove that they have grown up. Although families and schools prohibit them from smoking, rebellious psychology drives students' smoking rate to rise instead of falling.
Two. Suspicion of scientific propaganda.
Almost everyone knows that smoking does more harm than good, but some teenagers think that so many people smoke, don't they all live well? I've never seen anyone smoke to death. Under this psychological control, some minors have become "small smokers" without any precautions.
Three. Conformity psychology.
People around them smoke, and they are gradually influenced to accept and recognize this behavior. As the saying goes, "People who are close to Zhu Zhechi are black". What kind of friends a minor makes determines his behavior and habits to some extent.
Ⅳ. Entertainment psychology and melancholy psychology.
"A cigarette after a meal is better than a living fairy" has become the main purpose of smoking for some teenagers. The psychology of "fun, like a fairy" makes teenagers like cigarettes more and more.
ⅴ. Imitation psychology from adolescence.
The frequent occurrence of smoking scenes in film and television dramas is an important reason for the high smoking rate among teenagers today. Accompanied by the sense of adulthood in adolescence, it is the emergence of imitation psychology. Many teenagers like to learn from the characters in TV series and imitate their smoking movements, thinking that this is "very handsome, very chic and very graceful."
ⅵ. Seek psychological sustenance.
The growing competitive pressure and the generation gap with parents have gradually weakened the psychological support point of teenagers and need to seek new sustenance. Poor academic performance, disagreement with classmates, quarreling with parents at home or being scolded by parents lead to depression, which is another main reason for some teenagers to smoke.
3. "Not all children who smoke commit crimes, but almost all children who commit crimes smoke." . Because minors have no financial resources, in order to achieve the purpose of smoking, they will try their best to get money, which is easy to induce crimes such as theft and robbery. Some minors commit crimes just from the first cigarette. Smoking by minors is also easy to induce bad friends. Some students smoke together in groups of three or five, as a pleasure to oppose the positive education of family, school and society. In addition, minors who smoke are also easy to be used by criminals in society and embark on the road of illegal crimes.
Second, the impact of smoking on health:
A cigarette contains more than 4000 different chemicals, 43 of which are carcinogens, so every time you smoke a cigarette, you inhale these 4000 chemicals, shortening your life by 5 ~ 15 minutes. Listed below
The composition of cigarette and its influence on health, appearance and image are introduced.
Effects of cigarette ingredients on health
1) nicotine
1. Addictive components.
2. Each cigarette contains 1~ 1.5 mg of nicotine, of which 24% is directly absorbed by smokers when smoking, just as long-term inhalation of 60~70 mg will lead to death.
3. Nicotine increases blood viscosity, makes cholesterol accumulate in blood vessels, and increases the chance of vascular occlusion.
4. Blood pressure rises and the heart beats faster.
5. Gastric acid secretion increases, and smokers are prone to gastric ulcer.
6. Obstruct the delivery of oxygen.
2) carbon monoxide
1. Carbon monoxide can slow down blood circulation, lead to fat accumulation, block blood vessels and increase the risk of coronary heart disease.
2. Long-term inhalation of carbon monoxide will reduce the oxygen content in the blood, make people breathe easily, reduce exercise and accelerate aging. Inhalation can lead to hypoxia in the heart, brain and other organs.
3) Tar
1. "Smoke tooth", fingers turn yellow.
2. cough with phlegm.
3. Trachea tissue loses the function of eliminating waste, which increases the chance of lung infection.

Hydrogen cyanide (deadly poison gas)
Acetone (paint solution)
Methanol (missile fuel)
Termite poison (arsenic)
Other chemicals
Laryngeal cancer, chronic bronchitis, emphysema, lung cancer,
Angiosclerosis, stroke, heart disease, gingivitis,
Keywords Tao cancer, gastric ulcer, bladder cancer, stillbirth,
Premature delivery and weight loss.
Third, the harm of second-hand smoke:
When smoking cigarettes, smokers will only inhale about 15% smoke (that is, "mainstream smoke"), and 85% smoke will be released when cigarettes are idle, that is, second-hand smoke. In second-hand smoke, the content of some harmful substances is often higher than that of mainstream smoke, such as 2 times of nicotine, 3 times of tar stimulant and 5 times of harmful substances. Therefore, the health of non-smokers will also be affected by second-hand smoke, or even more seriously.
First, second-hand smoke may cause real-time discomfort, such as dizziness, headache, nasal discomfort, throat and eye irritation, heartbeat and asthma attack. Long-term inhalation of secondhand smoke will weaken lung function and increase the chances of respiratory tract infection and asthma. At the same time, non-smokers are forced to inhale a variety of carcinogens and toxic gases, which seriously affects their health.
ⅱ. Nicotine and carbon monoxide in the second-hand smoke inhaled by pregnant women will penetrate into the fetus through the blood, which will affect the absorption and health of the fetus, such as low birth weight and slow mental development. More serious will lead to miscarriage or premature death.
Three. Children inhaling secondhand smoke can lead to excessive phlegm and cough, which increases the chance of respiratory tract infection. At the same time, the risk of asthma and otitis media is greatly increased. Children are mentally immature, and it is easier to imitate adults to smoke. According to statistics, the number of children killed by secondhand smoke is much higher than that caused by other accidents. According to this study, if the spouse smokes, the average life expectancy of women will be four years shorter than that of women whose spouse does not smoke. At the same time, the spouse of a smoker is 25% more likely to have lung cancer and 20% more likely to have heart disease.
Conclusion:
1. Teenagers smoking is a way to hurt themselves. Perhaps because of some minor problems, I want to relax by smoking, but I still hope that teenagers or people of all ages will smoke less for their own health.
Smoking does great harm to people around you, so "cherish yourself and respect others".
3. The benefits of quitting smoking:
First, the body will tend to be healthy.
Two. Improve the appearance.
Three. Set a good example, enhance self-confidence and regain control of your life.
