First, the class teacher's theme introduction? Why are teenagers forbidden to smoke?

April 7th 1988 is the 40th anniversary of the establishment of the World Health Organization, and it has been designated as the first World No Tobacco Day with the theme: Tobacco or Health? On this day, shops all over the world are required not to sell cigarettes, and everyone does not smoke on this day. This resolution has won the support of the vast number of Member States. 1989 The World Health Organization has decided to designate May 3 1 day as World No Tobacco Day every year, and China has also designated this day as China No Tobacco Day.

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. 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. At present, there are 13- 18-year-old adolescents1300,000 in China. According to experts' estimates, there are about150,000 teenagers who have tried smoking, and the number of people who suffer from second-hand smoke is as high as 65 million.

In recent years, our college has attached great importance to tobacco control, established the Tobacco Control Office of Qingdao Vocational and Technical College, issued the Regulations on Tobacco Control on Campus of Qingdao Vocational and Technical College (Provisional), and published a schematic diagram of the location of smoking spots in the college, which provided teachers and students with information on smoking hazards, smoking cessation methods, smokers' diet and so on. On June 20 12, the Opinions on Further Strengthening Tobacco Control in Campus was released. However, the smoking problem of teachers and students in our college is still worrying, and the situation of quitting smoking is not optimistic. Although the school has repeatedly asked students not to smoke, there is always smoke in the campus, classrooms and offices, especially in the toilets and dormitories after school.

This situation not only affects the healthy growth of teenagers, but also seriously affects the improvement of the overall physical quality of our country, so the problem of adolescent smoking has attracted more and more attention from the society.

Second, the class teacher exchanged speeches.

(The following italicized text is the exchange speech of the class teacher)

First, the important factors affecting adolescent smoking

(A), leading to the psychological factors of minors smoking

Experts believe that there are six main psychological factors that cause minors to smoke:

1, pursuing style and adult psychology. Adolescence is a period of rapid growth of self-awareness. Almost from adolescence, many students feel that they are? My Lord. Yes 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.

2. Doubt scientific propaganda. ? Is smoking harmful? Almost everyone knows this, but some teenagers think that so many people smoke, don't they all have a good life? I've never seen anyone smoke to death. Under this psychological control, some minors become defenseless? Little smoker? .

3. herd mentality. People around them smoke, and they are gradually influenced to accept and recognize this behavior. What is the so-called? Near Zhu Zhechi, near Mexico. Is it black? . What kind of friends a minor makes determines his behavior and habits to some extent.

4. Entertainment psychology and melancholy psychology. ? A cigarette after a meal is better than a living fairy? Become the main purpose of smoking for some teenagers. Think? Fun, like a fairy? All kinds of psychology make teenagers more interested in cigarettes.

5. 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 dramas and imitate their smoking behavior. Do you think so? Handsome, chic and elegant? .

6. 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.

(2) Tobacco advertisements and promotion and sponsorship activities of tobacco enterprises induce teenagers to smoke.

Tobacco advertising, promotion and sponsorship link tobacco with sports, success, independence and sexiness. Beautifying the image of tobacco has a strong inducing effect on teenagers' smoking.

(3) Tobacco products are easily available, which opens the door for teenagers to smoke.

At present, the price of tobacco in China is low, there are many tobacco sales booths around the school, and there is no explicit prohibition on selling cigarettes in branches. Moreover? It is forbidden to sell cigarettes to teenagers under 18? The law has not been implemented and enforced, so young people can easily obtain tobacco products.

(d) Smoky environment in schools and families affects teenagers' smoking.

Teenagers spend most of their time at school and at home, and the people who have the most contact with them are teachers, peers and parents. Therefore, smoking is an important factor affecting teenagers' smoking behavior. School environment, school spirit and school discipline also have significant influence on students' smoking behavior.

Second, the harm of smoking

(A) the mental harm of smoking

? 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.

Effects of smoking on health.

Tobacco (including smoke released during combustion) contains nearly 4,000 known chemical substances, most of which are harmful to human body, including alkaloids such as carbon monoxide and nicotine, amines, nitriles, alcohols, phenols, alkanes, aldehydes, nitrogen oxides, polycyclic aromatic hydrocarbons, heterocyclic compounds, hydroxyl compounds, heavy metal elements, organic pesticides and so on. It has a wide range and many biological functions. The following lists the main harmful components of cigarettes and their effects on health, appearance and image:

1, nicotine

Nicotine, also known as nicotine, is a colorless and transparent oily volatile liquid with a pungent smell of smoke.

Nicotine is the main source of addiction. It takes only 7.5 seconds to inhale nicotine from cigarette smoke to reach the brain, which makes smokers feel a mild and pleasant feeling, which can make the central nervous system excited first and then inhibited. The half-life of nicotine in plasma is 30 minutes. When nicotine is below a stable level, smokers will feel fidgety, unwell, nausea and headache, and they are eager to smoke to supplement nicotine. Each cigarette contains 1- 1.5 mg of nicotine, of which 24% is directly absorbed by smokers when smoking. 1 Nicotine in cigarettes can be poisoned 1 mouse. Nicotine in 25 grams of cigarettes can poison a cow. 40-60 mg of pure nicotine can poison people. Relevant experts have obtained the following results through animal experiments: a horse will die soon after injecting 8 drops of nicotine; Dogs can kill it by injecting a drop of nicotine intravenously; In addition, after long-term smoking, it can be found that some animals have a tendency of vasoconstriction and even obvious sclerosis.

(1) Nicotine increases blood viscosity, makes cholesterol accumulate in blood vessels, and increases the chance of vascular occlusion.

(2) Nicotine raises blood pressure and quickens the heartbeat.

(3) Nicotine increases gastric acid secretion, and smokers are prone to gastric ulcer.

(4) Nicotine will hinder the delivery of oxygen.

(5) Smoking will hinder people's absorption of vitamin C, and nicotine has a direct destructive effect on vitamin C. If people lack vitamin C for a long time, they may suffer from scurvy.

2. Carbon monoxide

This is a colorless and odorless gas. People often say that gas poisoning means carbon monoxide poisoning.

Each cigarette can produce 20-30 mg of carbon monoxide when burning. If many smokers gather in crowded and unventilated rooms, the concentration of carbon monoxide in the air can reach 0.05%, which is close to the concentration of gas poisoning.

The hemoglobin concentration of normal people who don't smoke is about 0.5%, while that of heavy smokers is as high as 15%-20%. That is to say, 15%-20% hemoglobin loses the function of transporting oxygen, leading to hypoxia.

(1) Carbon monoxide slows blood circulation, causes fat accumulation, blocks blood vessels, and increases the chance 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. Smoke tar

It is a brown sticky resin, commonly known as. Smoke oil? . Smoke tar contains many carcinogens. Moreover, it will adhere to the surface of the trachea, bronchi and alveoli of smokers, causing physical and chemical stimulation and damaging the respiratory function of the human body.

( 1)? Smoking and shit your teeth? , fingers turn yellow.

(2) excessive phlegm and cough.

(3) Trachea tissue loses the function of eliminating waste, which increases the chance of lung infection.

4, benzopyrene

Benzopyrene is a strong carcinogen.

5. Radioactive substances

Cigarette smoke contains lead 2 10 and polonium 20 1, which can be absorbed into the lungs and deposited in the body when smoking. They emit radiation continuously for a long time, damaging lung tissue.

A person who smokes 20 cigarettes a day inhales radioactive elements a year, which is equivalent to 300 X-ray chest films taken by smokers 1 year.

6. Irritating compounds

Tobacco smoke contains a variety of irritating compounds, including hydrogen cyanide, formaldehyde and acrolein. For example, 1 filter-free cigarettes can produce 45 micrograms of acrolein and 100-400 micrograms of hydrogen cyanide, which destroys bronchial mucosa and weakens the function of alveolar macrophages, making the lungs and bronchi vulnerable to infection.

7, harmful metals

Tobacco contains harmful metals such as arsenic, mercury, cadmium and nickel. Take cadmium as an example, its harm is that cadmium can accumulate in the body, causing asthma and emphysema. Trace cadmium can kill sperm in vas deferens and affect fertility. A large amount of cadmium enters bone tissue, causing decalcification, deformation and brittleness of bone, which is prone to fracture. 1 cigarette contains cadmium 1-2 micrograms, of which 5% is absorbed by human body.
