What are the hazards of being in a smoking environment for a long time?

As early as 20 12, it was pointed out in the Report on the Health Hazards of Smoking in China issued by the former Ministry of Health that there are 69 known carcinogens in tobacco smoke, which will cause key gene mutation in the body, disorder the normal growth control mechanism, and eventually lead to cell canceration and malignant tumor.

The report also believes that second-hand smoke contains a lot of harmful substances and carcinogens, and non-smokers exposed to second-hand smoke will also increase the risk of various smoking-related diseases. "Secondhand smoke contains carcinogens and forms smog in indoor space, so exposure to secondhand smoke in indoor public places is more harmful."

In addition, there is no so-called safe level of second-hand smoke exposure, even if it is exposed to second-hand smoke for a short time, it will do harm to human health. In the indoor environment, no matter adding exhaust fans, air conditioners or other equipment, it is impossible to avoid non-smokers from being harmed by second-hand smoke. The only way to effectively prevent non-smokers from being exposed to second-hand smoke is to completely ban smoking in indoor environment.
