I believe everyone knows that the harm of tobacco is one of the most serious public health problems in the world today and the biggest risk factor for human health. At present, the total number of smokers in the world has exceeded 654.38+0.3 billion, and nearly 5 million people die from smoking every year. For this reason, in1987165438+10, the United Nations World Health Organization suggested that 1988 should be designated as the first World No Tobacco Day, and then it should be fixed as May 3 1 day every year. The activity aims to warn the world that smoking is harmful to health, call on people to quit smoking and create a healthy living environment for themselves.

According to research, nicotine contained in cigarettes can poison a mouse, while nicotine contained in a pack of cigarettes can poison a cow. Smoking a pack of cigarettes every day is equivalent to inhaling 50-70 mg of nicotine. If you take these doses at one time, people will die. Besides nicotine, about 5,000 compounds produced when cigarettes are lit are the chief culprit of cancer.

In a statement released this year, the World Health Organization pointed out: "Today, tobacco has become the second biggest killer in the world. The damage caused by smoking is more serious than that caused by SARS and the recent tsunami. If the current trend is maintained, by 2020, 654.38+0 billion people will die prematurely because of smoking. "

Since tobacco is so terrible, why do so many people smoke? There are two main reasons: first, nicotine contained in tobacco is addictive, which makes people dependent and difficult to quit; Another reason is that most people have not regarded smoking as an ugly habit that harms others and themselves. On the contrary, they think it is a very fashionable and unique thing. Therefore, there are more and more smokers, and people rely on it more and more.

However, the tobacco dealer said, "The cigarettes we produce are for those who have no knowledge, young people and stupid people." China is the largest producer and consumer of cigarettes in the world. More than one third of the cigarettes in the world are smoked by people in China. Teenagers account for a large proportion of smokers in China. For teenagers, the harm of smoking is far greater than expected. It will also affect the growth and development of bones. This is because teenagers are in the stage of rapid physical growth and development, the organ system of the body is not yet mature, the resistance to various toxic substances is not strong, and the poison of smoke is deeper, which may even lead to premature aging and premature death. Smoking may also make teenagers develop bad habits, induce bad behavior and even lead to crime. Anti-smoking has become an urgent task in China. Our government has put forward the overall goal of reducing the total number of smokers in China by 1. 1 billion in the next 25 years. Secretary 1 14 All rights reserved. In order to actively respond to the government's call and for our own health, we call on all students to consciously stay away from cigarettes and persuade their relatives and friends who smoke to give up smoking as much as possible. After all, cigarettes are harmful to us. After all, the air without tobacco will be fresher, and the life without tobacco will be more gorgeous!
