Speech on Smoking Harmful to Health (World No Tobacco Day) Dear teachers and students,
Good morning!
? Smoking is harmful to health? People have been paying attention to this topic, and everyone knows that smoking is very harmful to our health. In the past 50 years, the incidence and mortality of lung cancer have risen rapidly all over the world, especially in industrialized countries. Among men who died of cancer, lung cancer has ranked first. A large number of epidemiological studies have confirmed that smoking is the primary risk factor for lung cancer. In order to arouse the international community's attention to the harm of tobacco to human health, the World Health Organization suggested that May 3 1 day of each year be designated as World No Tobacco Day.
Nicotine, carbon monoxide and other metal compounds in cigarettes are very harmful to human body, especially to teenagers. Medical research shows that teenagers are in the period of growth and development, and their physiological systems and organs are not yet mature. Their resistance to harmful factors in the external environment is weaker than that of adults, and they are easy to absorb poisons. According to the survey, the age of starting smoking is directly related to the mortality rate of lung cancer. /kloc-the mortality rate of smokers under 0/5 years old was19.68%; 20 ~ 24 years old10.08%; 4.08% are over 25 years old. This shows that the earlier you start smoking, the higher the incidence and mortality of lung cancer. At the same time, smoking can also damage the brain, slow thinking, reduce memory, affect study and work, and make students' academic performance decline. Psychological research shows that the intelligence efficiency of smokers is lower than that of non-smokers 10.6%.
We often hear people say? A cigarette after dinner makes you happy like a fairy? But this is not the case. The disadvantages of smoking are like countless stars. There are three dangerous chemicals in tobacco: tar, nicotine and carbon monoxide. Three wonderful speeches on the 20-year World No Tobacco Day and three wonderful speeches on the 20-year World No Tobacco Day. Tar is a mixture of several substances, which will be concentrated into viscous substances in the lungs; Nicotine is an addictive drug, which is absorbed by the lungs and mainly acts on the nervous system. Carbon monoxide reduces the ability of red blood cells to deliver oxygen to the whole body. In fact, tobacco is also a kind of drug, but it is not so violent and the country has not banned it.
Smoking will not only pose a threat to your health, but also do great harm to people who smoke passively around you. Like poison, these cigarette butts are slowly approaching us, which also poses a great threat to our life and work. If you are in the smog every day, your body will become weaker and weaker, and diseases will always infringe on you and even endanger your life. Horribly, a person who smokes/kloc-0.5 to 20 cigarettes a day has a higher risk of lung cancer, oral cancer or laryngeal cancer than a non-smoker/kloc-0.4 times. The risk of dying from esophageal cancer is four times higher than that of non-smokers. The possibility of dying from bladder cancer is doubled; The risk of dying of heart disease is twice as high. Smoking is the main cause of chronic bronchitis and emphysema, and chronic lung disease itself will increase the risk of pneumonia and heart disease, and smoking will also increase the risk of hypertension.
Now, I solemnly appeal to everyone to actively publicize the scientific knowledge that smoking is harmful to health, let your relatives and friends put down their cigarettes, form a good atmosphere of smoking ban, and put smoking ban into the track of spiritual civilization construction.
Do we all have to do it? Smoke-free teenagers? Be the master of civilization!
Let's live happily with our families and create a better future together!
Speech on smoking is harmful to health (World No Tobacco Day) II. Dear teachers and students:
Good Morning, everyone!
The theme of my speech under the national flag today is life education.
Students, do you know what day this Friday is? May 3, 20001day is the _ _ th World No Tobacco Day initiated by the World Health Organization. I believe every student must know that tobacco is one of the most serious public health problems in the world today, and it is also the biggest risk factor for human health. Despite this, there are still about 65.438+300 million smokers in the world, and nearly 5 million people die every year because of smoking.
At present, the average age of smokers in China is getting younger and younger, and teenagers account for a large proportion. Smoking has become a big killer affecting the healthy growth of teenagers in China, which has aroused widespread concern in the whole society. 1991on June 29th, the 20th meeting of the 7th the National People's Congress Standing Committee (NPCSC) passed the tobacco monopoly law of People's Republic of China (PRC), which will? Discourage teenagers from smoking and prohibit primary and secondary school students from smoking? , conspicuously written in the first chapter of the general provisions of article 5.
So, do you know how harmful smoking is to human body? A large number of scientific studies have proved that smoking is very harmful to human health. All tobacco contains toxins, which can lead to various fatal and disabling health problems; The risk of smokers suffering from cancer, especially lung cancer, heart disease, emphysema and other fatal diseases will increase significantly.
According to the survey of the World Health Organization, one person dies of smoking every 6.5 seconds in the world. Cigarettes have become the second biggest killer after hypertension, and 80% of tumors, 75% of chronic obstructive diseases and 25% of coronary heart disease are related to cigarettes. Especially for teenagers, it is more harmful.
According to the research of medical scientists, teenagers are in the period of growth and development, and their physiological systems and organs are not yet mature. Their resistance to harmful factors in the external environment is weaker than that of adults, and they are easy to absorb poisons and damage the normal growth of their bodies. Moreover, smoking can also damage the brain and affect intellectual development.
Students, are you still indifferent after hearing so many shocking figures? Don't you have to rush into the toilet again and again inexplicably, secretly and nervously, and be silent in the so-called smoking pleasure? Is it necessary to smoke and laugh outside school, like nobody's business?
There is only one life, which is a gift from parents and God. It carries the responsibilities entrusted to you by your relatives, friends and the whole society. So, please cherish every day of your life, and from today on, quit smoking, love life and create a better life! Only by feeling and appreciating life with your heart can you truly appreciate the beauty of life.
Speech on smoking is harmful to health (World No Tobacco Day) Speech under the national flag of the third World No Tobacco Day
Dear teachers and students:
Good morning everyone. It's an honor to stand under the national flag and give a speech to you on No Tobacco Day. I hope you don't be people who endanger your health.
Smoke does great harm to people's lungs, heart and other internal organs, and even leads to death. This shows that smoke is very harmful to people! Of course, cigarettes are more like our twelve-year-old teenagers? Grenade's temper burns as soon as it is pulled? .
As far as I know, there is a harmful chemical element nicotine in cigarettes. A pack of cigarettes contains about 50 to 100 ml of nicotine. If you take so much nicotine at once, the consequences will be unimaginable. But don't mistakenly think that as long as you don't smoke so much at a time, you will be fine. You know, cigarettes are drugs, and toxins can penetrate into the brain in just ten seconds, making people like people. Get lost at the crossroads and can't tell the difference between southeast and northwest? , lead to? Addiction? , can no longer extricate themselves. Well, what can we do? One small step, an everlasting regret? Where!
Cigarettes can't be sold in the market, but I want to criticize those smokers who can't control their addiction and take the initiative to walk into the store to pay for it. Is that so? Love cigarettes like life? I really don't understand what's so good about smoking that it can kill people. Maybe they just ruined his (her) future because of temporary confusion.
Many schools put them on the walls now? No smoking? Announcement. I think this approach is correct. I once saw on the Internet that there were about 60,000 teenagers smoking in China in 20 years. This figure is extremely shocking and even a little sad.
Because there are many teenagers smoking? Secondhand smoke? And addicted to cigarettes; But it's okay now. Our school, other schools and public places all over the country are promoting quitting smoking and not smoking. The United States, China and other countries all designate May 12 as the National Day every year? World No Tobacco Day? .
You may say that some cigarettes are said to be non-toxic, so this kind of cigarettes can be smoked. I don't agree with this statement. Now some unscrupulous businessmen cheat consumers in order to make money. So it's best not to smoke, as I said before. Ecstasy soup, totally addictive? If you are tired of smoking, you must try to give up smoking, otherwise you will be pale and emaciated, but by that time it will be too late, you know, there is nothing in the world? Regret medicine? Oh!
? People on earth are good at living. The same nature varies from upbringing to upbringing. ? I appeal: I hope all parents will take care of their next generation and keep him away from drugs. You know, cigarettes kill not one or two children, but many, many children.
Although many people smoke in society, my family is smoke-free, and I feel a little relieved.
I hope there are more such families in the world; Let the future flowers of the motherland live in a smoke-free environment and make the world better.
My speech is over. Thank you.
Speech on Smoking Harmful to Health (World No Tobacco Day) 4 Dear teachers and students:
Hello everyone!
May 3 1? World No Tobacco Day? The theme of my speech today is Love Children on World No Tobacco Day.
Class, mention it? World No Tobacco Day? Are you like me, there is a voice in my ear shouting: smoking is harmful to health, please stay away from cigarettes!
A small cigarette is so small in everyone's eyes, but if you really understand its harm, you will be dumbfounded! Let's listen to the self-introduction of cigarettes:
Hello everyone! My name is cigarette. People all over the world know that everyone likes me very much. Especially men, most of them are mine? Fans? .
From my fingers, there are about 654.38+03 billion people in the world who are keen on me, and there are about 350 million people in China! Although I look small and unremarkable, I am very skilled! To tell you the truth, there are more than 4000 compounds in my body. What, you don't believe it? I don't want to brag, but all our cigarettes are the best. If we smoke one, we will inhale billions of composite particles, and suddenly we will be full of energy.
But the particulate matter you inhale contains carcinogens such as nicotine, tar, ammonia and benzene, among which tar alone contains dozens of carcinogens, and nicotine can also be addictive.
According to scientists, nicotine in cigarettes can kill a mouse! Probably because I was too presumptuous, the World Health Organization conducted a special investigation on me. It is said that one person dies every 6.5 seconds in the world because of inhaling me, and about 5 million people die of diseases related to me every year. He also said that I have become the second killer after hypertension, and 80% of tumors, 75% of chronic obstructive pulmonary disease and 25% of coronary heart disease are related to me.
Really didn't expect to give it to me? Fans? It caused so much damage, and I felt a thrill when I heard this terrible fact. Probably because I hurt people too much, people set May 3 1 to? World No Tobacco Day? . Although a little unhappy, I decided to remain silent after examining my own misdeeds.
Students, I don't know how you feel after listening to the self-introduction of cigarettes. I think you must have a creepy feeling like me. Look at the smokers around you: when you meet, you toast warmly and offer cigarettes, and you look like you are sharing weal and woe. They regard these cigarettes containing toxic substances as a communication tool and enjoy the temporary pleasure brought by smoking, but they never thought that while enjoying themselves, his family, his friends and some innocent people around him were all hurt by the smoke. If you smoke two cigarettes in a poorly ventilated room, the indoor air pollution will be 20 times higher than that outside.
Smoke is not a good thing. Students, please start today. Cigarette self-introduction? Tell it to the smokers around you, and persuade them to quit smoking and have a healthy body again!
Thank you!
