What are the pros and cons of smoking, and what are the stakes of smoking?

Smoking has no benefit at all, and family members also follow the smell of passive smoking, polluting the environment and affecting their own health and the health of their families. It is easy to induce lung cancer.

Is smoking beneficial? I've never heard of it, but I've heard that smokers are prone to lung cancer and die! Or those oncogenic factors cause genetic mutations in the body, activating the body's proto-oncogenes, thus causing people to get cancer.

Nicotine, carbon monoxide, and tobacco tar in the smoke not only directly harm the mucous membrane of the respiratory tract, but are absorbed into the blood or dissolved in sputum and swallowed, but also further aggravate the harm to the human body, which is the main culprit of lung cancer, chronic obstructive pulmonary cancer, coronary heart disease, etc. Smoking is the first culprit of lung cancer, more than eighty percent of lung cancer patients die from smoking-related, about 1 million people die from smoking-related diseases in China every year, 10 people die from tobacco-related diseases every minute in the world, 2 people die from tobacco-related diseases every minute in China, and the diseases and deaths caused by tobacco will be more serious in the next 30 years. Ninety percent of the smoke from tobacco combustion is directly emitted in the air to form second-hand smoke, which contains hundreds of known toxic or carcinogenic substances, including formaldehyde, benzene, vinyl chloride, arsenic, ammonia and other second-hand smoke, which have been identified as Class A carcinogens by the International Agency for Research on Cancer.

Smoking is harmful, and nicotine contains a lot of harmful substances such as carbon monoxide.

According to a new study, smoking a cigarette can cost a person eleven minutes of life, if you smoke a pack of 20 cigarettes a dayIt may be about three hours and forty minutes less life. This estimate is based on men who started smoking at the age of 17 and died at an average age of 71.

Suppose he, like the average British addict, smokes fifteen cigarettes a day, he will consume thirty-one thousand six hundred and eighty-eight cigarettes in his lifetime. On average, smokers will die six and a half years earlier than non-smokers.

About one-third of the population in the UK currently smokes, and about 120,000 people die a year from smoking-related diseases, two-thirds of whom are cancer and heart disease. The researchers hope that this new study will encourage more people to make up their minds to quit smoking at the dawn of the new century.

Smoking is harmful, not only endangering human health, but also having a negative impact on society. As long as there are signs of life, any organized organism must breathe, exhale carbon dioxide from the body, inhale oxygen from the air, and metabolize it to maintain normal life activities.

People who don't smoke can breathe in a lot of fresh air every day; People who smoke regularly, however, do not enjoy the blessings of nature, and inhale not fresh air, but toxic gases polluted by smoke.

Tobacco contains the toxic nicotine, also known as nicotine. 1 gram of nicotine can poison 300 rabbits or 500 mice. If you inject 50 mg of nicotine, it can be fatal.

Smoking is the most harmful to the respiratory tract and can easily cause laryngitis, tracheitis, emphysema and other diseases. When you smoke, smoke enters through the mouth, through the throat, trachea, bronchi, and into the bloodstream. Smoking causes men to lose their Y chromosomes and increase the risk of cancer.

Smoking has only disadvantages, not benefits, and it can be said that there are many harms but no benefits. There are many harms of smoking, mainly in the following aspects:

1. The biggest harm of smoking is that the patient's lung function is damaged, and long-term smoking will cause the patient to develop emphysema and even lung cancer;

2. Long-term heavy smoking will also cause damage to the patient's heart function and cause cardiovascular and cerebrovascular diseases;

3. In addition, the probability of malignant tumors such as oral cancer, throat cancer and esophageal cancer in patients who smoke is greatly increased;

4. Smoking will also affect the patient's nerve function, affect the patient's brain function, and change the patient's sense of smell, taste and reproductive function;

5. The aging speed of people who smoke for a long time will also be accelerated, and teeth and bones will be deformed, brittle and even fractured.

In fact, there are many harms of smoking, especially the probability of suffering from various malignant tumors will increase for people who are hungry and blind for a long time. In addition, people who smoke second-hand smoke for a long time will also have a lot of harm, so try not to be in the same room as people who smoke.

The stakes of smoking refer to the relationship between the benefits and harms of smoking. The main benefits of smoking are: 1. Smoking can provide short-term comfort and relieve stress; 2. Smoking can make people have social relationships and make people feel more influential; 3. Smoking can improve people's ability and make them more energetic; 4. Smoking can change people's mood and make them more pleasant.

However, smoking also has many harms: 1. Smoking can lead to lung diseases, such as chronic bronchitis, lung cancer, etc.; 2. Smoking can lead to cardiovascular diseases, such as heart disease, stroke, etc.; 3. Smoking can lead to respiratory diseases, such as asthma; 4. Smoking can lead to other diseases, such as hepatitis, kidney disease, etc.; 5. Smoking can pose a threat to the baby's health, such as birth defects, low birth weight, etc.

In conclusion, the stakes of smoking are extremely uneven, and the benefits of smoking are far less harmful than the harms, so you should quit smoking to protect your health.
