What is the composition of the smoke that wafts out after the cigarette is lit.

Cigarettes have nicotine in themselves, so naturally there will be a bit of nicotine.

Of course, there are other bad ingredients that can cause cancer.

In a word: Smoking is bad for your health.

Please do not copy Thank you.

Nicotine and carbon monoxide are both toxic.

The smoke released when tobacco is burned contains more than 3,800 known chemicals, most of which are harmful to the human body, including carbon monoxide, nicotine and other alkaloids, amines, nitriles, drunkenness, phenols, alkanes, aldehydes, nitrogen oxides, polycyclic aromatic hydrocarbons, heterocyclic compounds, hydroxyl compounds, heavy metal elements, organic pesticides, etc., a wide range, they have a variety of biological effects, causing various harms to the human body.

Nicotine. The most active substance in cigarette smoke is extremely toxic and acts quickly. 40-60 mg of nicotine is as lethal as cyanide. Nicotine is one of the main substances that cause addiction.

Tar. Produced when a cigarette is lit, its properties are not much different from bitumen. Some analyses have shown that tar contains about 5,000 organic and inorganic chemicals, which are the culprits of cancer.

Nitrosamine. Nitrosamines are extremely strong carcinogens. Tobacco produces a tobacco-specific nitrosamine (TSNA) during fermentation and when ignited.

Carbon monoxide. When smoking, tobacco does not burn completely, so more carbon monoxide is produced. Carbon monoxide binds to hemoglobin, affects cardiovascular blood oxygen**, promotes high cholesterol, and can also indirectly affect the formation of certain tumors.

Radioactive material.

Tobacco contains a variety of radioactive substances, of which polonium-210 is the most dangerous. It can emit rays.

Other harmful and carcinogenic substances.

In addition to the above-mentioned harmful substances, the harmful substances in cigarettes are benzopyrene, which is a strong carcinogen. In addition, the metal cadmium, benzidine, vinyl chloride, etc. in smoke will play a role in contributing to the formation of cancer cells.

When the smoke is made, take the one inside to express Yu Ming's respect and gratitude to the person who smokes.

In the hearts of the Chinese, generally put good things outside to use good things to receive each other, to show politeness, and the party that accepts the grand servant wants to take the one inside, which shows humility and respect.

There are different ways to smoke cigarettes. Especially for elders, peers, juniors or friends, or people you don't know. When handing cigarettes to elders, the cigarettes that pop out of the cigarette box are high and low, and the one that cannot be taken high in etiquette is disrespectful to the elders.

Be humble with that low cigarette. When handing cigarettes to peers, the cigarettes that pop out of the cigarette box are high and low, and the person who receives the cigarette should press the high and low ones to take one at will according to etiquette. When handing a cigarette to a junior, the junior who receives the cigarette should show humility and receive the cigarette with both hands.

Because of the hot air principle.

Smoke is indeed denser than air, and will fall to the ground after a long enough time. But a lit fire causes the surrounding air to warm up, causing thermal convection. As a result, the solid particulate matter produced by combustion is carried up by the rising warm air.

And air is a bad conductor of heat, and it takes a long time for hot air to cool to ambient temperature, so hot air will keep rising.

If you burn a fire indoors, the smoke will rise with the hot air and then attract to the roof, and it will not fall when the air cools. If it is outdoors, the smoke will gradually blow away as it rises.

Summary. If the cigarette butt falls off when smoking, it may indicate that you will be more unlucky recently, which is a sign of bad luck, but usually it will not be bad luck, it may be the loss of some small money, if you have the habit of playing cards, the cigarette butt may also mean that you will lose when you play cards recently, which is not a good omen.

What does smoking and dropping the cigarette butt portify.

If the cigarette butt falls off when smoking, it may indicate that you will be more unlucky recently, which is a sign of bad luck, but usually it will not be bad luck, it may be the loss of some small money, if you have the habit of playing cards, the cigarette butt may also mean that you will lose when you play cards recently, which is not a good omen.

What a crack. In terms of Feng Shui metaphysics, different geographical environments will have different aura forces. Therefore, when you are unlucky, you should not go to some green mountains and clear waters to change your luck and drive away bad luck.

I'm smoking at night, and I accidentally hung it when I flicked the ashes, so I guess it's fine.

This may be the loose tobacco or it may be an exciting thing, and the excitement is too strong.

What we usually call smoke is actually composed of many small solid particles, and they are in their original state, so the density is definitely greater than that of air.

We often see the fact that when the sun shines into a room, you can see a lot of dust floating in the air, and their movement is similar to the movement of smoke, except that they are more dispersed, not as concentrated as smoke, they move with the air current.

Smoke is generally produced with hot gases, and the hot gases move upwards due to their low density, forming an updraft, and substances with very low mass such as smoke will move upwards with the updraft.

The above one said that smoking in the sauna also floats upward, I think he thinks a little less, in the sauna the content of water vapor is very large, so that the density of the gas in the whole house is increased, so the density of the gas spit out of the mouth is still small, and the water vapor in the sauna will form an updraft. This will also drive the smoke upwards.

Hot air is lighter than cold air. So the smoke burns underneath, and the hot air rises and the smoke rises.

We know that smoke tends to go up. Now we can give it a try and see if it's possible to get the smoke down.

Find a cardboard box for shoes (or a cardboard box for snacks), a candle, two glass covers from kerosene lamps, and a piece of used kraft paper. I couldn't find the glass cover for a while, so I could use two metal cylinders (old chimneys used on the stove), but the observation effect was not as good as the transparent glass cover.

Make two holes in the lid of the carton that are slightly smaller than the diameter of the glass cover or metal cylinder. Place the candle and the two lampshades as shown in the picture. Note that the candle should be placed directly below one of the glass covers.

Light the candle and close the lid, taking care not to burn the carton on fire. At this time, light the kraft paper with a match and bring the smoking kraft paper to the top of the lampshade on the right. Soon, you see the smoke coming from the burning brown paper coming out of the glass cover and into the box, and then out of the other lampshade again.

It turns out that warm air is lighter than cold air, and when a candle is lit, it heats up the air on it, causing it to rise and come out of the lampshade. But the air had to be replenished from below, so that the air could only enter through the entrance of the other shade. The force of the air entering the lampshade is enough to inhale the smoke, so we see the "abnormal" phenomenon of the smoke coming down.

The world is full of strange things, for example, smoke can drift downward.
