Is secondhand smoke really more harmful than firsthand smoke?

Secondhand smoke is indeed more harmful than firsthand smoke. In fact, we all know that whether it is first-hand smoke or second-hand smoke, it is very harmful to our body, so what is the difference between them? Why is secondhand smoke more harmful than first-hand smoke?

1. The difference between first-hand smoke and second-hand smoke

The smoke emitted by people when they smoke can be divided into mainstream smoke, exhaled smoke and lateral smoke. Mainstream smoke is what we usually call first-hand cigarettes, which refers to smoke that smokers inhale directly into the body when a tobacco product is burning. Secondhand smoke, on the other hand, is a general term for exhaled smoke and sidestream smoke.

Exhaled smoke refers to smoke exhaled by a smoker, while sidestream smoke refers to smoke that enters the air directly from the cigarette butt when a tobacco product is burned.

Secondhand smoke and first-hand smoke are both tobacco product smoke and have little difference in composition. And the smoke of tobacco products contains hundreds of harmful substances. At least 69 of them are carcinogens.

The three most well-known harmful substances are nicotine, carbon monoxide and tar, in addition to some lesser-known harmful substances such as vinyl chloride, ethylene oxide, beryllium, nickel, etc., which are all defined as a class 1 carcinogen by the International Agency for Research on Cancer.

2. Why is second-hand smoke more harmful than first-hand smoke?

Tobacco contains a large amount of nicotine and tar and other harmful substances, which can easily cause throat diseases after entering the human body, such as pharyngitis, tonsillitis, and in severe cases, it can also cause throat cancer or lung tumors.

1. In the case of insufficient combustion, the toxicity of harmful components produced by second-hand smoke per unit mass is indeed greater than that of first-hand smoke. In daily life, the more fully a substance is burned, the more volatilization will be. However, due to the fact that tobacco products are often in a state of insufficient combustion when burning, the content of harmful components in second-hand smoke will be several times or even several times higher than that of first-hand smoke.

After the cigarette enters the respiratory tract through the mouth, most of the harmful substances are less than 10%, and the remaining harmful substances are in the air, which will enter the body of friends or family members around you through breathing.

Secondhand smoke lasts longer than firsthand smoke because the longest time to smoke a cigarette is less than half an hour, while secondhand smoke can persist indoors for hours or days, and can last for months in poorly ventilated environments.

Therefore, it is recommended that people with smoking habits can quit smoking as soon as possible, do not smoke indoors when they must smoke, and do not smoke in non-smoking places, you can go to an outdoor relatively empty environment and smoke away from crowded environments, which can make second-hand smoke dissipate quickly and avoid second-hand smoke from causing damage to other people's bodies.

Yes, secondhand smoke is indeed more harmful than firsthand smoke.

This is actually a strategy to persuade people to quit smoking, the smoke produced by cigarette combustion, part of which is inhaled by smokers, is called mainstream smoke, and those that float out during the combustion process are called flow smoke (you think, a kind of "filtration" through the filter and the smoker's lungs, a direct combustion out, which is more toxic).

The so-called second-hand smoke includes the mainstream smoke exhaled by smokers, and also includes the flow of smokeExposure to secondhand smokeIt must be more toxic than first-hand smoke, but the smoker himself smokes second-hand smoke in addition to first-hand smoke.
