Smog or smoking, which is more harmful to the body?

Smoking is a personal hazard or a hazard to people around you, and the scope is relatively small, but smoking is easy to cause cancer and chronic obstructive pulmonary disease.

Haze is air pollution, which is a large area and is caused by air pollution in a region. There are dust particles in the air, which will also do some harm to our respiratory system after inhalation.

Smoking is self-controlled, and smog is air pollution caused by everyone, which is uncontrollable. If we want to compare, I think both of them are very harmful to our health.

Moreover, dust pollution is harmful to lung organs, except that some people may have allergic reactions in a short time, such as bronchial asthma, interstitial lung disease and allergic alveolitis. Most people get sick because of their contact time and the concentration of air pollution in this area

I remember reading a report that when PM2.5 reaches 670 micrograms per cubic meter, smoking a cigarette is equivalent to breathing for one day, while the value of outdoor serious pollution PM2.5 is more than 350 micrograms per square meter.

Moreover, the smoke produced by cigarette burning contains a lot of PM2.5, which contains thousands of known chemicals, most of which are harmful to human body, including known harmful components such as carbon monoxide and nicotine, and also contains heavy metal elements and organic pesticides. , has a wide range of biological functions, causing various hazards to the human body.

Therefore, although smog and smoking will do harm to human body, smoking is more harmful. Therefore, in order to be healthy, we should smoke as little as possible, but don't forget to wear a mask when going out in foggy days.
