Help me sort out some information about the harm of smoking to health.

At present, there are 1 1 billion smokers in the world, and the number of people who die from smoking-related diseases is as high as 4 million every year. On average, one person dies of diseases related to smoking every second. It is estimated that smoking reduces the average life expectancy of American adults 14 years. Among the adults who died of smoking, 39.8% died of cancer, 34.7% died of vascular diseases and 25.5% died of respiratory diseases. Smoking has become an urgent problem that seriously endangers health, harms human living environment, reduces people's quality of life and shortens human life. Therefore, the United Nations designated May 3 1 as the Global Quitting Smoking Day, and the World Health Organization regarded smoking as a plague in the 20th century.

Tobacco contains more than 20 kinds of toxins after burning, and nicotine is the most harmful to life.

Three Harms of Smoking

Because the smoke inhaled in the body has a malignant stimulating effect on respiratory tract, digestive tract and other organs, some people think that it is an inducing factor for gastric and duodenal ulcers, respiratory tract infections, and even cancers such as oral cavity, lips, tongue, esophagus and respiratory tract.

From this point of view, smoking is harmful to human health. So try to quit smoking or smoke less. Non-smokers had better not get into this hobby.

Examples of smoking causing great harm to health:

In the French Smoking Competition in 2000, one person even smoked 43 cigarettes and died on the spot in public places such as bus stops, hospitals and shopping malls. We often see eye-catching words such as "smoking is harmful to health". Cigarettes are the most familiar to everyone, and smoking is also a very common phenomenon in today's society. From elderly grandparents to teenagers, how many people are not obsessed with it? But do you know how harmful it is? Smoking is like drinking "chronic" poison! According to scientists' research, cigarettes contain a lot of nicotine, which is a very toxic substance, damaging human health and causing terrible lung cancer, gastric cancer, esophageal cancer and various diseases! A drop of nicotine can poison a fat pig and shorten people's life span by five seconds! Three drops of nicotine can poison a strong cow! You can imagine how harmful it is!

There is a group of experiments called: the harm of cigarettes. First, I found three bottles of the same size, which contained the same clear water, and then I found this small fish of the same species and size, which was usually used to smoke a cigarette. The experiment has begun! The first bottle contains no tobacco, the second bottle contains a little tobacco, and the third bottle contains a lot of tobacco. Then stir the three bottles with a stick. After a while, the water in the first bottle is still very clear, while the water in the second bottle turns pale yellow; The water in the third bottle turned khaki! Then, put the small fish into these three bottles respectively. After a while, the situation is very different! A terrible change has taken place, and the small fish in the first bottle is still safe and sound; The little fish in the second bottle struggled desperately; The small fish in the third bottle has a stiff tail and only its mouth is still breathing weakly. Tick tock, tick tock. The most painful moment for Xiaoyu has come! The murderous god of death took the lives of these two guys with no effort! In such a short time, two lively and lovely little fish remained motionless and became hard little zombies! Only in the first bottle without tobacco, the small fish is still swimming happily.

From the above experiments, it is proved that cut tobacco can poison small fish. Humans smoking it will also cause different degrees of harm.

Now, do you know about cigarettes? I think so, too. cigarettes are terrible! Smokers buy them at a high price, thinking that they can bring happiness to themselves, but they don't expect to destroy their healthy bodies and even their offspring like that!
