Which is more harmful, electronic smoke or real smoke

The answer is:real cigarette.

Compared with electronic cigarettes, real cigarettes are more harmful to the lungs, because the smoke and dust produced by cigarette combustion contain more than 7000 kinds of chemical substances, including hundreds of harmful substances, such as benzopyrene, nitrosamine β- Naphthylamine, cadmium, polonium, etc., of which 69 are carcinogens. When these toxic chemicals enter the body, they will quickly enter the blood through the lungs and spread to all tissues and organs of the body, causing immediate damage to the body. Particles in soot are more likely to escape the defense mechanism of the respiratory system. Then it precipitates in the respiratory mucosa and enters the blood through the alveoli, causing damage to the lungs, blood vessels and surrounding tissues, inducing inflammation and causing damage to lung function.
