Will smoking not damage the lungs? You don't think so when you know the path of smoke in your body
We all know that smoking is harmful to health, but for those who are addicted to smoking, unwilling to quit smoking or unable to quit, they often like to deceive themselves and even make up a set of lies to numb themselves. The most common three sentences are: Smoking is not enough. Lungs, spit it out of the mouth is less harmful; the doctors I know smoke, they say smoking is not so scary; people around me who have been smoking for decades are alive and well, but non-smokers die of lung cancer etc.
Many people think that the lungs are actually the smoke released by not swallowing cigarettes when smoking. However, toxic gases such as carbon monoxide contained in the smoke will exist in the air around the human body. In this way, as long as you need to breathe, these harmful gases will enter your body with the air you breathe, which is equivalent to second-hand smoke. Second-hand smoke that has not been filtered by a filter is more harmful than first-hand smoke, such as smoking rooms in public places and chess and card rooms in residential areas. These are high-risk areas. There are many smokers, and the house is full of smoke, and the visibility is plummeting. In this kind of environment, smoking one stick can top the usual one pack. Even if you don’t have the habit of smoking, sitting in the chess and card room for an hour or two is more harmful than smoking two or three packs of cigarettes.
When smoking, harmful substances will adhere to the mucous membranes of the respiratory tract, such as the mouth, nose, and throat of the human body. Over time, these toxic substances will induce malignant transformation of epithelial cells in these parts and cause cancer. It can even enter the digestive tract with food and saliva, increasing the incidence of esophageal and gastric cancers.
The human body is a whole, and the blood vessels in the mouth are also extremely rich. Even if the smoke does not enter the lungs, it only exists in the mouth. Countless toxic substances in cigarettes can still be absorbed through the oral mucosa and enter the blood circulation to affect the whole body, especially the heart. Greater impact. Moreover, cigarette damage to the oral mucosa is also very serious, which can cause oral ulcers, loose teeth, and even oral cancer.
In addition, people who have smoked lungs may be afraid of the harm of smoking, and they will restrain themselves from smoking less. Many people think that smoking is not enough for the lungs. This way of smoking does not cause great harm to the body, and is not really smoking. This will inadvertently smoke more cigarettes. The more you pump, the more damage your body does to your lungs.
