Are there any benefits to smoking occasionally? What happens if you smoke for a long time

Occasional smoking may be detrimental to the body, rather than good for the body. Smoking is one of the important pathogens of lung cancer, especially squamous epithelial cell carcinoma and small cell undifferentiated carcinoma, and the risk of lung cancer in smokers is 13 times that of non-smokers. Nicotine and carbon monoxide in cigarettes are recognized as the main harmful factors causing coronary atherosclerosis, and the incidence of coronary heart disease, hypertension, cerebrovascular disease and peripheral vascular disease in smokers is significantly increased.

Smoking can damage and shorten the cilia of the bronchial mucosa, affecting the removal function of cilia, thereby inducing respiratory diseases such as chronic bronchitis, emphysema and chronic airway obstruction. In addition, smoking can also cause an increase in gastric acid secretion, inhibit the secretion of sodium bicarbonate by the pancreas, increase the duodenal acid load, and induce ulcers.

Formal research institutions believe that smoking is harmful and not beneficial, but in fact it is not. Smoking a cigarette once in a while may open up your mind and relax your mind, or it may be better for your body and money, as long as you don't smoke for the sake of smoking, as the writer says, "This person has nothing left, some are just addicted to smoking", and that's it.

There is no harm but no benefit, so don't touch it if you can!

According to statistics, the risk of lung cancer from long-term smoking is about 20 times that of lifelong non-smokers, and the cumulative risk of lung cancer from a large number of long-term heavy smokers is as high as 30%, and the risk of lung cancer from people who have never smoked is much smaller. Smoking is associated with a higher risk of lung cancer, while never smoking has a significantly lower risk of lung cancer.

Smoking can promote the body's secretion of dopamine, so that the brain is excited, as long as it is not an addiction, occasional smoking in life can not only activate the brain, but also make two men who do not know each other quickly become friends, but also a means of making friends, the so-called tobacco paving the way and drinking bridges also has a certain reason.

Depending on the physical condition of the individual, you feel that liking is a benefit, because when you smoke, you are in a good mood.

It's good to suffer less in the world.

Smoking is bad for your health and has no benefits.

No, there is no benefit to smoking.

No, don't leave anything to chance, even one bite is harmful.

Smoking can also be a form of healing. In the past, many diseases could be caused by smoking**. But this method is now lost.

Generally speaking, there is not much harm, and it is a process of slow accumulation.

The harm of smoking to the human body is cumulative, that is, chronic. Most people will only realize the dangers of smoking when they fully feel the symptoms, or even when the doctor clearly says that "it is caused by smoking".

The biggest impact of smoking is the lungs, I believe we have seen smokers' lungs, especially those old smokers, because of long-term smoking, the lungs have become very black, and smoking is also particularly prone to various lung diseases, including bronchitis and so on.

Long-term smoking will lead to a decrease in a person's immune system, which will increase the possibility of disease invasion, which will cause symptoms such as heart disease and arteriosclerosis.

2. Long-term smokers, his blood will become viscous and blood pressure will continue to rise, resulting in myocardial infarction, slowing down of blood circulation and other consequences, and the final impact will be further worsened.

Third, in many ** channels, we can see the long-term smoker lungs, it is really creepy, long-term smoking is very harmful to the lungs and bronchi, will increase the chance of lung cancer, bronchitis, once you have these diseases, it will be regretted, not only to their own lives threatened, but also to the family burden.

Long-term smoking is very harmful to the respiratory system and cardiovascular system of the human body, and the harmful chemicals released when cigarettes are lit include carbon monoxide, nicotine, aldehydes, nitrides, phenylpropylene ratio, amines, as well as heavy metals, aminophenol and so on There are more than 40 kinds of harmful chemicals. Smoking is the main predisposing factor of chronic bronchial and chronic obstructive pulmonary disease, and long-term smoking can shorten the cilia of the bronchial mucosa, and there is irregular movement or dyskinesia, which affects the removal function of cilia. Submucosal gland hyperplasia, mucus secretion increases, if not eliminated in time, may cause bronchial obstruction, which is harmful to the respiratory system.

The incidence of coronary heart disease, hypertension, cerebrovascular disease and peripheral vascular disease in smokers is significantly higher than that of non-smokers, and the incidence of acute myocardial infarction is also significantly higher. There is also a carcinogenic effect, not only lung cancer, but also tongue cancer, oral cancer, esophageal cancer, etc., the incidence of cancer is much higher than that of non-smokers.

If you smoke for a long time, it is easy to cause your lungs to get diseases, such as pneumonia and lung cancer, which can easily affect your bronchi.

Long-term smoking can also lead to impaired cardiovascular function, which can lead to coronary heart disease, hypertension and other cardiovascular diseases. Tobacco can cause coronary heart disease in a variety of ways, such as nitric oxide secreted by the normal vascular endothelium, and smoking can affect the secretion of this substance and affect the dilatory function of blood vessels. Smoking also promotes platelet aggregation and promotes thrombosis.

The nicotine in cigarettes can damage the heart conduction system, induce arrhythmias, increase the risk of sudden cardiac death, and increase the chance of coronary arteriosclerosis and thrombosis. The morbidity and mortality of coronary heart disease, myocardial infarction, and cerebral insufficiency also increased significantly with the increase of smoking.

Smoking is harmful to health. It is advisable to quit smoking as early as possible.

Long-term smoking can not only cause harm to people's physical health, but also cause damage to the individual's economy. It may also have an impact on family life.

At present, although the country is advocating smoking cessation, it is still producing ** cigarettes.

I sincerely hope that you who smoke less can swallow clouds and spit fog! Northeast Net, Oct. 20 -- Danish scientists reported on Tuesday that at least a quarter of people who smoke heavily for a long time will develop chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, which is one of the leading causes of human death. COPD begins with cough, fatigue, and shortness of breath, and destruction of lung tissue can cause difficulty breathing.

According to Reuters 16**, researchers at a Danish hospital followed 8,000 people for 25 years and found that one in four smokers had COPD. Dr Peter Lange, who was involved in the study, said: "The absolute risk of COPD in long-term smokers is at least 25%, far exceeding the original estimate.

Both smokers and non-smokers were the subjects of this study. Prior to the start of the study, pulmonary function tests were performed on the subjects, and regular pulmonary function tests were performed over the course of the next 25 years of the study. Studies have shown that persistent smokers suffer from COPD six times more than non-smokers, and the findings were published in the journal Thorax.

If smokers quit shortly after the study began, the risk of developing COPD decreased. People who quit smoking did not have severe COPD. Of the participants, 2,900 died, of whom 109 died from COPD.

"The results we came to were simple: people who smoke for a long time have a higher risk of COPD," Lange said.

The number of deaths from COPD is increasing. The World Health Organization estimates that by 2020, COPD will be the third leading cause of death in the world's population. COPD has been plaguing people over the age of 40 who have smoked for years.

Smoking can also cause other diseases, such as pneumonia, heart disease and stroke. COPD cannot be completely studied, and its methods of relieving symptoms and delaying the progression of the disease are being studied.

Long-term smoking will cause great harm to the body, first of all, reduce the body's immunity, thereby increasing the risk of diseases, such as inducing cardiovascular disease, stroke and so on. In addition, the process of smoking produces a lot of smoke, and the harmful substances in the smoke will enter the lungs, which will harm lung health; And the carbon monoxide in it can take a toll on the brain.

Nowadays, many people want to relieve the pressure of life and work, or often have stressful situations, and if the number of smoking is not frequent, it usually does not have a great impact on the body. For some long-term smokers, it is easy to suffer from various diseases, which will cause great harm to the body. So, what are the dangers of long-term smoking?

1. Reduce human immunity.

For long-term smokers, the body's immune system decreases, making it easier for bacteria or viruses to invade the body, increasing the risk of developing diseases, such as hardening of the arteries. In addition, tobacco contains a lot of toxic substances, which can cause damage to the nerves, and the carbon monoxide content contained in it is very high, and long-term inhalation can cause a lack of oxygen to the brain.

2. Induce cardiovascular disease.

Long-term smoking can easily induce cardiovascular disease, because cigarettes release large amounts of cyanide and carbon monoxide during combustion. When these substances are inhaled into the body, the amount of oxygen in the blood decreases, resulting in a rapid heartbeat, an increase in blood pressure, and if the patient has a bad heart, it is likely to induce heart disease. And according to a large amount of data, people who smoke for a long time have a much higher chance of developing coronary heart disease and high blood pressure than non-smokers.

3. Endanger lung health.

In the process of smoking, a large amount of smoke is produced, which contains harmful substances such as tar, carbon monoxide, nicotine, etc. These harmful substances will enter the lungs with smoke, so for long-term smokers, toxins will become more and more in the lungs, resulting in lung dysfunction, and will also cause a variety of lung diseases, seriously endangering lung health.

4. Induce stroke.

Cigarettes contain a large amount of nicotine, and long-term inhalation of nicotine will promote the release of epinephrine, which can easily cause vasospasm or contraction, which will increase the pressure of blood circulation. If you don't quit smoking in time, it will cause damage to the blood vessel wall, leading to arteriosclerosis, which can induce stroke.

5. Harmful to brain health.

Cigarettes release a large amount of carbon monoxide during combustion, which enters the lungs with breathing, swallowing up oxygen in the blood, thereby reducing the oxygen level in the brain and affecting blood circulation. If you smoke for a long time, it will harm your brain health, and you can easily suffer from some brain diseases.

It's getting worse and worse, both physically and mentally. Smoking is detrimental to good fortune.

Smoking is a real health hazard.

Because tobacco contains nicotine (nicotine), it is highly toxic. It has been reported that nicotine in one cigarette can poison 10 mice, nicotine in 25 cigarettes can poison a cow, and 40 60 milligrams of nicotine can kill people. Nicotine damages brain cells, causing central nervous system symptoms in smokers; It causes increased blood pressure, rapid heartbeat, and even arrhythmia and heart disease; Causes stomach pain and other stomach problems; Damage to the bronchial mucosa, causing chronic bronchitis.

More seriously, tobacco dramatically increases the risk of cancer in the lungs, mouth, pharynx, larynx, esophagus, pancreas, bladder and renal pelvis, as well as cancers and leukemia in the nasal cavity, sinuses, stomach, liver, kidneys, cervix. Their danger is determined by how long and how much smokers smoke. For some smokers, alcoholic beverages can also exacerbate the health effects.

However, there is also evidence that smoking does not cause breast cancer and can reduce the frequency of cancer of the uterine wall.

There are no clear results showing the association between smoking and the risk of rectal, colon and prostate cancer.

Some of these types of cancer are more likely to be affected by objects in the smoker's field, smoker drinking, and smoker infection.
