Hello, smoking is bad for your health. Smoking is a very harmful behavior to health, tobacco includes the smoke produced, contains hundreds of toxic and harmful gaseous substances, this kind of internal damage is local direct contact damage, airway damage or lung damage.

There are also some substances that enter the blood through the lungs, so they will cause damage to the whole body, especially the blood vessels, the blood vessels of smoking patients are relatively bad, including lung cancer, such as stomach cancer, some cardiovascular events are obviously related to smoking, there are many articles that can be confirmed, so it is recommended that everyone try to quit smoking.

Smoking is harmful but not beneficial, not only affecting the health and life of smokers, but also polluting the air and endangering others. Clause.

First, it can mainly cause some lung diseases, cigarettes contain a variety of toxic chemicals, mainly tar, nicotine, carbon monoxide, dioxins, etc., which can damage the mouth, trachea and lungs, and can cause chronic bronchitis, emphysema, pulmonary interstitial fibrosis and other diseases.

2. Cause cardiovascular-related diseases, smoking can constrict coronary arteries and cause myocardial infarction. At the same time, it can cause increased heart rate, increased cardiac load, and lead to the occurrence of cardiovascular and cerebrovascular diseases. Clause.

3. Smoking can also cause cancer, the most common is lung cancer, and it can also cause bladder cancer, esophageal cancer, etc. Smoking can also cause osteoporosis, which can lead to early menopause. Men lose the ability to have sex and have children, and smoking in pregnant women can lead to premature birth of the fetus.

Smoking can also affect people's attention, affect people's intelligence and memory, and seriously affect the efficiency of work and study, so it is recommended to quit smoking as soon as possible.

Smoking, we all know that it is harmful to health, we think that it may have a greater impact on the lungs, because secondhand smoke will lead to an increase in the incidence of lung cancer, but the impact of smoking on blood vessels, you may not be too clear, smoking, in fact, it plays a role in the cardiovascular system. What happens when our blood vessels are excited, it contracts, why do our blood vessels contract, then let's think about it, many times we have to reach a point where our brains are excited. We need more blood to get to the brain, so how do we get more blood to the brain?

It is called to adopt the principle of redistribution. In this case, the blood vessels in many parts of the body will constrict, reducing the blood**, and most of the blood** will be supplied to the brain to think about problems. So it's actually a non-physiological state, but smoking can achieve this state.

Although this state of affairs produces a comparison in a short period of time, we may say that it is inspiration, or that there is something that we as artists need. However, it constricts the blood vessels of the whole body, and this harmful contraction will lead to atherosclerosis of the blood vessels, and further lead to damage to the blood vessels, so the impact of smoking on the function of the heart is also very huge. So we don't advocate smoking.

The harm of smoking to health is undoubted, decades of clinical studies have shown that smoking is harmful to health, there are more than 7,000 kinds of chemicals in tobacco, hundreds of harmful substances, and 69 kinds of carcinogenic ones. Smoking is not only related to lung cancer, but also closely related to other malignant tumors, including oral cancer, nasopharyngeal cancer, esophageal cancer, and liver cancer.

In addition to tumor-related, it is also closely related to other systems, such as the respiratory system, including chronic obstructive pulmonary disease, asthma, pneumonia, bronchitis, and bronchiectasis. Smoking has also been linked to cardiovascular disease, such as myocardial infarction. Smoking and cerebrovascular diseases are also related, such as stroke, these four major diseases constitute the main body of chronic diseases in China, accounting for more than 80% of deaths in China.

Smoking is not harmful to health, everyone knows what is written on the cigarette box, smoking is a very harmful behavior to health, tobacco includes the smoke produced, contains hundreds of toxic and harmful gaseous substances, this kind of internal damage is local direct contact damage, airway damage or lung damage.

There are also some substances that enter the blood through the lungs, so they will cause damage to the whole body, especially blood vessels, the blood vessels of smokers are relatively bad, including lung cancer, such as stomach cancer, some cardiovascular events are obviously related to smoking, there are many articles that can be confirmed, so it is recommended that everyone try to quit smoking.

The popularity of smoking is from a small number of people to most people, and most people smoke to have a market, so some people will give up planting mulberry to change to cigarettes, large-scale planting is the Wanli period, and the beginning of smoking is the Chenghua period.

Cigarettes are imported products, is imported products, the original Ming Dynasty did not have the technology to grow cigarettes, nor did they have the technology to fry tobacco and flue-cured tobacco, until the Wanli period or before Wanli did learn the technology of fried tobacco and flue-cured tobacco. Because the emperor of the Ming Dynasty smoked and ignored the government, Huang Taiji banned smoking, and Chongzhen also banned smoking.
