There are always people who use other people's lungs as their own ashtrays. More than 70% of people are being forced to "take drugs"!
This is talking about second-hand smoke, and in recent years, there have been more and more "crusades" against second-hand smoke:
"People who hate the office the most smoke, there are always people who smoke by themselves, and when they meet people, they must separate the smokers, and walk back and forth in the office while smoking..."

"My dad smoked, and I smoked secondhand smoke for 22 years, and I found myself often out of breath, and my brain reacted slower than my peers, but my dad saw it and said: Who let you stay up late."
Second-hand smoke has become one of the problems that generally endanger national health, but it has not attracted enough attention, and the mainland has even banned indoor smoking in recent years.
More than 70% of people: are being forced to "take drugs"
China has the largest number of smokers in the world, with an estimated 316 million people smoking and 740 million passive smokers [1].
This means that more than 7 adults are inhaling secondhand smoke.
The harm of second-hand smoke to the human body is already a cliché, and its harm to the human body is no less than that of "drugs", in which there are about 7,000 kinds of chemicals, hundreds of harmful substances, and at least 69 carcinogens.
If it feels too abstract, let's say something concrete:
(1) Children continue to inhale second-hand smoke, and the harm will even last until middle age
Children continue to inhale second-hand smoke, may appear lung growth and function decline, resulting in asthma, pneumonia and bronchitis onset and worsening, annual medical expenses ranging from about 1w, suffering diseases like warm boiled frogs, some diseases can not even be cured.

(2) Adults continue to inhale secondhand smoke, which is equivalent to standing at the Fukushima Nuclear Power Plant for 2 hours
Adults continue to inhale second-hand smoke, can cause serious cardiovascular and respiratory diseases, women may cause skin aging, hair loss, annual medical expenses of more than 2w, and even do not smoke but suffer from lung cancer.
(3) Pets will also inhale second-hand smoke, shortening their life span by 3~7 years
Research by the University of Glasgow in the United Kingdom found that if the owner of the pet smokes, it will increase the risk of oral cancer and lymphoma, and the risk of cancer in cats and dogs who smoke second-hand smoke is 3 times higher than that of cats and dogs who do not smoke second-hand smoke, and the life span of some pets will even be shortened by 3~7 years.
The World Health Organization has already calculated that in 2014 alone, the direct losses caused to us by China's treatment of tobacco-related diseases were about 53 billion yuan, accounting for about 1.5% of China's health expenditure of 3.5 trillion yuan in the same year[1].
As long as I'm far enough away, won't I inhale secondhand smoke?
Belch... Hardly.
Studies have calculated that the smoke produced by burning a cigarette contains many harmful substances, of which phenylpropylene is as high as 180 nanograms, and if smoked in a 30-cubic meter room, it will cause a concentration of 6 nanograms per square meter.
According to current health standards, more than 1 nanogram per cubic meter is harmful, and one cigarette causes six times more pollution than normal standards [3].
In other words, second-hand smoke can cause harm in at least 30 cubic meters of space.

However, once there is second-hand smoke indoors, only by changing the air 5~6 times can the air hygiene standards be reduced to the allowable range.
However, many air conditioners used in offices, hotels and homes do not have the function of filtering and removing such ultrafine particles.
So in these scenes, once the smoke of the cigarette is formed, it is very difficult to remove.
In a poorly ventilated environment, as long as second-hand smoke is exposed to a room full of smoke for 1h, the person who inhales it is equivalent to smoking a cigarette [3].
Is the second-hand smoke produced by electronic cigarettes harmless?
No.
Smoking e-cigarettes does not produce water vapor, but some second-hand aerosols, which are equivalent to "second-hand smoke", which also contain nicotine and even carcinogens such as formaldehyde.
The mainland's control of PM2.5 has gone through a long process, but e-cigarettes can be easily destroyed: second-hand aerosols of e-cigarettes can cause PM1.0 values to be 14-40 times higher and PM2.5 values to be 6-86 times higher.
At the same time, e-cigarette second-hand aerosols produce higher metal content (such as nickel and chromium) than traditional cigarettes, these substances grow like hard "iron", inhaled into our body, may cause infertility, stomach ulcers, stomach cramps and other problems.

Therefore, whether it is second-hand smoke from smoking or second-hand aerosols produced by using electronic cigarettes, it is harmful.
How can long-term exposure to second-hand smoke reduce the harm?
If you are forced to stay in a second-hand smoke environment for a long time, you can protect yourself from these aspects.
Pay attention to ventilation
Even if the ventilation of the environment where secondhand smoke is present is troublesome, we cannot be sloppy, and we can speed up ventilation with these methods:
Summer fan: Place it at the source of secondhand smoke, blow it towards the window, and choose the maximum wind force.
Open more windows in winter: choose one or two windows, open one-third, and open all doors and windows regularly for thorough ventilation at noon or morning when there are few people.
Professional masks against secondhand smoke
Ordinary masks cannot filter secondhand smoke, including the blue medical masks we wear every day.
Secondhand smoke is an oily particle, so it is best to use a mask with a higher level of protection (the product standard can be seen on the packaging on the back of the mask), mainly the mask with the product standard GB/NIOSH type, which can prevent the odor of organic vapor and filter oily particles.

Place greenery
Although green plants have little effect on purifying the secondhand smoke environment, they can also be used as an additional option:
> hanging class:
hanging orchid, green rose, ivy, bubble leaf cold water flower, Swedish ivy, duck toe grass, etc.;
> large greenery:
Loose-tailed anemone, fishtail, anemone, dracaena, fortune tree, emerald, etc.;
> cactus:
Golden tigers, cacti, measuring rulers;
> Apricots:
Raw stone flowers, flesh decorations;
> Sedum category:
Wasson, stone lotus, purslane, swallow palm;
> aloe vera:
Aloe vera of Curacao, Haworthia, etc.
If it is a family with pets, you can choose gerberas and drug-addicted grass, and it is harmless for pets to gnaw in small amounts.
Do a special experience
Below is a checklist for people who have been exposed to secondhand smoke for a long time:
Advise others to quit smoking
Persuading people to quit smoking is the most fundamental method, the exhortation of family and friends around them will be more useful than strangers, and in addition to verbal admonition, there can also be some actions, such as sticking some words of exhortation on the smoker's cigarette box.
In addition, families with small children or pregnant women should minimize contact with people who smoke. Choose a non-smoking car when boarding the bus and a non-smoking room when staying at a hotel.
Of course, if you don't smoke, you don't have anything.
Some data studies have shown that lung function will be significantly improved after 12 weeks of smoking cessation, the risk of coronary heart disease will be half that of smokers after 1 year of smoking, and the risk of stroke will be reduced to normal after 5 years of quitting smoking.
Quit smoking, a simple and cheap way to get health back, why not?
