What are the dangers of secondhand smoke? Why is secondhand smoke more toxic than firsthand smoke? Secondhand smoke can easily cause asthma, and secondhand smoke can easily cause heart disease.

Why is secondhand smoke more toxic than firsthand smoke? Because the smoke of first-hand smoke may last for 5-10 minutes, but the smoke of second-hand smoke in the air may last for half an hour or even an hour, and it will not dissipate for longer. People around who smoke passively, in the environment of secondhand smoke, are harmed for a longer period of time.

1.This is because when a smoker inhales a cigarette, less than 10% of the smoke produced by the cigarette contains harmful substances, and the rest of the smoke is all emitted into the air. At this time, in the smoke formed by second-hand smoke, the surrounding non-smokers inhale relatively more harmful substances, and the natural harm is greater.

Moreover, second-hand smoke lasts longer than first-hand smoke, and people who passively smoke around them will be harmed for a longer time in the environment of secondhand smoke.

2.Secondhand smoke lasts longer than firsthand smoke. Because the smoke of first-hand smoke may last for 5-10 minutes, but the smoke of second-hand smoke in the air may last for half an hour or even an hour, and it will not dissipate for longer.

People around who smoke passively, in the environment of secondhand smoke, are harmed for a longer period of time. In general, secondhand smoke has a relatively high content of toxic substances. Secondhand smoke contains more nicotine, which is harmful to the human body.

Not only does smoking cause lung cancer, secondhand smoke can also cause lung cancer. Smoking greatly increases the incidence of cancer. People who inhale secondhand smoke are about six times more likely to get cancer than others.

3.Secondhand smoke can easily cause asthma because children's breathing rates are much higher than normal. Therefore, if people around you smoke, it is easy for the child's heart to beat faster and trigger asthma.

Heart disease, secondhand smoke is easy to cause heart disease, because secondhand smoke is easy to make the heart sticky, it is difficult to get up early, greatly reduces the frequency of regulating blood vessels, and it is easy to cause heart disease for a long time. In case of illness, it is very harmful to the heart, and the patient must pay attention. Secondhand smoke is very harmful to the human body and it is necessary to put an end to it.

If you are pregnant, you should pay attention to the fact that secondhand smoke can easily cause fetal malformations, so it has a great impact on the fetus.

4.Regular smoking can also cause damage to the liver. The liver is responsible for metabolism.

After the smoke enters the body, it also passes through the liver. Smoking too much can put a strain on the liver. When your liver becomes heavier, your metabolic capacity decreases, which can lead to a high amount of bad cholesterol in your body.

Eventually, your liver will get more and more damaged.

It can cause lung cancer, which may cause a violent cough, and it can also affect your respiratory tract, which can lead to pneumonia or lung cancer. Most of the smoke is emitted into the environment, and then the body inhales second-hand smoke and inhales more soot.

Smoking secondhand smoke is particularly likely to lead to lung cancer, respiratory tract infections, frequent coughing, ** will be particularly poor, and pores are particularly large. Because nicotine from secondhand smoke is difficult to excrete and will accumulate in the body.

It may cause us to suffer from hyperlipidemia, high blood pressure, diabetes, as well as liver cancer, lung cancer, and stomach cancer. Because second-hand smoke generally reacts with the air and produces some toxic substances.

Difficulty breathing, cough, sore throat, etc. When you inhale second-hand smoke, you will choke on yourself, it is easy to breathe, and inhaling too much second-hand smoke will make your throat sore and cough.

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.

That's impossible, or first-hand smoke is more harmful, but second-hand smoke people are generally not smokers, so they are passively harmed, so people will say this, in fact, it is still a new hand, that is impossible, or first-hand smoke is more harmful, but second-hand smoke people are generally not smokers, so they are passively harmed, so people will say this, in fact, it is still a person who smokes first-hand cigarettes, and the harm they get is greater, after all, it is the original drug.

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

Secondhand smoke has many harmful substances, which can cause us to breathe hard, and even cause undesirable conditions such as suffocation; Secondhand smoke can affect our immunity, cause great damage to our respiratory system, and easily cause bronchitis and chronic pharyngitis; Secondhand smoke increases our chances of cancer and affects a child's brain development.

It can lead to lung infections, increase the risk of lung cancer, increase the risk of asthma, weaken immunity, and ageing, so avoid secondhand smoke so as not to burden the body.

Second-hand smoke is indeed much more harmful than first-hand smoke, because when the smoker inhales cigarettes, only less than 10% of the harmful substances in the smoke produced by cigarettes are inhaled into the lungs of smokers, and all the remaining smoke will be emitted into the air. At this time, in the smoke formed by second-hand smoke, the surrounding non-smokers inhale relatively more harmful substances, and the harm is naturally greater. Also, secondhand smoke lasts longer than firsthand smoke.

Because the smoke of first-hand smoke may last for 5-10 minutes, but the smoke spread by second-hand smoke in the air may last for half an hour, or even an hour, and it will not disperse for longer.

Because when smokers inhale cigarettes, only less than 10% of the harmful substances in the smoke produced by cigarettes invade the lungs of smokers, and the rest will be discharged into the air. It can cause allergies in the human body, it can also cause dizziness and fatigue, it can cause itching in the pharynx, it can also lead to difficulty breathing, and even shock.

It is said that secondhand smoke is more harmful than direct smoking, is this true? At the junction of each locomotive, the small needs of long-distance travel, I believe that people who brush the headlines will generally choose high-speed rail and bullet trains to do trains, and they will not have the trouble of second-hand smoke! Don't embarrass those ordinary ordinary smokers in order to be famous, or to reflect your high profile!

There is a smoking area. In the regulations on the management of sanitation in public places, although it is said that it is not allowed to smoke on the road that pedestrians must pass.

Occasionally smelling a little smoke will not make you damage your body immediately, it is better to be more tolerant, don't be alarmist and unconventional! We strongly urge the transportation department to consider the human rights of smokers, and as long as the country does not ban smoking, smoking rooms should be set up in each waiting area! And it should be more convenient in all aspects, so I took the green car.

Even if it takes a long time, if you are afraid of second-hand smoke, you can take the high-speed train or plane! Do you have your right to say that the smoker is an alien? He has no human rights, no rights.

I've been to Thailand, where the ban on smoking is very strict, cigarettes are not allowed to be sold openly, and smoking in places where smoking is not allowed is punishable by heavy fines. But there are smoking spots in almost all places. Didn't feel too much inconvenience.

Inferior citizens have nowhere to tell their grievances, and those who don't smoke deduct everything from the smoker. Just as what a person doesn't like, others should not like her, everyone has their own hobbies, and everyone's hobbies should be free and free from interference.

It takes 48 hours from Harbin to Sanya, and I personally think that smokers try to smoke as little as possible, and people who are afraid of second-hand smoke try to close the door of the carriage, but in fact, a large amount of smoke has been smoked away, and there will not be too many people who can float into the carriage. In addition, the carriage link is better ventilated than the carriage, and the smoke will be sucked out of the carriage when the train is running. There could be no second-hand smoke drifting into the carriage.

There is also no harm from secondhand smoke.
