Smoking is harmful to our health, but some people smoke for decades and still live healthily. Just like Chairman Mao, the great leader we know, he is a smoker who never leaves his hand, but Chairman Mao's health has always been great, unlike what we know: smoking will hurt your health.

So many people will have doubts: smoking should be harmless to the body, even if it is, it is not as terrible as it is said. ?

In fact, smoking is really harmful to health, but everyone has different genes and different detoxification effects on harmful substances in smoke. This is the main reason why some people smoke healthily, while others smoke but get lung cancer.

For example, after some people smoke, the body will soon excrete the harmful substances in these cigarettes through the detoxification genes of the body, so that these harmful substances will not stay in the body for a long time and do little harm to the body. After a period of rest, the body will return to a state of non-smoking. However, after smoking, some people lack this detoxification gene or the function of this detoxification gene is very weak, which will make it difficult for harmful substances in smoke to be excluded from the body after smoking, thus accumulating in the body for a long time and causing harm to the body. The longer the time, the greater the harm. If you continue to smoke, the harm will accumulate and eventually lead to disease.

To sum up, smoking is really harmful to the body, but everyone has different genes and different tolerance to cigarette toxins, which leads to some people being healthy all their lives.
