There are two main differences between e-cigarettes and ordinary tobacco cigarettes in terms of hazards, which are the difference in tobacco composition and the difference in atomization. Let’s talk about it today, here we go.

1. As far as the ingredients are concerned, electronic cigarettes are far less harmful than traditional tobacco cigarettes.
Undoubtedly, tar is the most harmful to ordinary smoke. Tar refers to a layer of brown greasy substance remaining in the cigarette holder during smoking, commonly known as smoke oil. A very intuitive change in the smoking process is that the color of the filter gradually darkens as you smoke, and the fingers holding the cigarette will also be smoked. Meanwhile, the teeth will be stained with a dark color after smoking. The root cause is tar.
Tar is more than just discoloration. In fact, it is the product of incomplete combustion of organic matter under oxygen-deficient conditions. Therefore, it contains a lot of organic substances, many of which are carcinogens, such as benzopyrene, cadmium, arsenic, and β. A variety of carcinogens such as tea, amines, and nitrosamines, and cancer-promoting substances such as phenols and fumaric acid. Because of this, ordinary tobacco has become a class of carcinogens listed by the International Agency for Research on Cancer under the World Health Organization. In addition, cigarette tar can accelerate the aging of human blood vessels, resulting in gradual hardening of blood vessels and loss of elasticity, leading to cardiovascular diseases. Many other diseases are often caused by tar. Therefore, the first advice of many disease doctors is to quit smoking.
So does e-cigarette have tar? The answer is no. One of the biggest advantages of e-cigarettes is that they do not contain tar. Instead, they use safe VG (glycerin) and PG (propylene glycol) as alternatives, both of which are common organic solvents and safe ingredients contained in skin care products, at least there is not enough evidence that they are harmful.
Nicotine is another important ingredient in tobacco, and it is also a well-known tobacco ingredient. Its physical harm is not as serious as cigarette tar, but nicotine has a very troublesome problem, that is the addiction, that is why it is difficult for smokers to quit. At this point, both electronic cigarettes and ordinary cigarettes have nicotine. However, there is still a difference between the two. Because the nicotine of ordinary tobacco is contained in tobacco and is a product of tobacco growth and secretion, reducing nicotine in ordinary tobacco is a very difficult topic (because tobacco is a physical processing process, nicotine is not No reduction. If chemical measures are taken to reduce nicotine, it will inevitably lead to changes in tobacco flavor and affect tobacco sales). On the other hand, nicotine is directly added in electronic cigarettes, so the ratio of nicotine can be controlled, and even zero nicotine can be achieved.
Some people often hear that e-cigarettes have excessive formaldehyde. Is it true? First of all, we need to find the right reference object. This conclusion is based on the comparison between electronic cigarettes and ordinary air. What if e-cigarettes are compared with tobacco? The answer is that ordinary smoke is larger. In fact, the combustion of ordinary smoke itself produces high concentrations of formaldehyde.
Moreover, the appearance of formaldehyde substances is mainly due to unqualified e-liquid. Unfortunately, the current national regulations for e-cigarettes have not yet been issued, so you can only choose brands recognized by more e-cigarette companies when purchasing.
Combustion vs atomization
We know that ordinary cigarettes need to be burned before they can be smoked, and the process of burning is also a process of large amounts of harmful substances in tobacco. As we all know, combustion is a chemical reaction process, ordinary tobacco, after burning, will produce a lot of substances. Due to the uneven combustion of tobacco and the extreme temperature difference at different locations, it is equivalent to the diversification of chemical reaction conditions, so a lot of harmful substances are born, which is also the most important factor in the harm of tobacco. Electronic cigarettes are different. Electronic cigarettes do not burn, but simply heat and atomize. Generally, the atomization temperature of electronic cigarettes is controlled at 250-350℃, and some electronic cigarettes can even achieve low-temperature fog of 220-250℃. This temperature is much lower than the 700-800°C of ordinary tobacco, and this will greatly reduce the harm of e-cigarettes and reduce the production of harmful substances. This is another important reason for the low harm of e-cigarettes.
What is more, the generation of particulate matter is also an important factor. Particles near μm can enter the human body and cause serious harm, such as cardiovascular disease. The combustion of traditional tobacco will produce a large amount of solid suspended particulate matter. The figure below shows the contribution of tobacco combustion to indoor particulate matter pollution. We can see that after smoking tobacco, a large amount of particulate matter is produced, which occurred from PM1.0 to PM10. As it rises more than twice, these solid particles are sucked into the human body and adhere to the throat, trachea, lungs and other places. They cannot be decomposed. Over the years, they will cause irreversible diseases such as throat cancer, tracheal cancer, and lung cancer.
What about electronic cigarettes? The atomization of e-cigarettes can also produce particles, which is fundamentally different from the particles produced by ordinary cigarettes. The particles are liquid particles and will be absorbed or eliminated when entering the human body. For example, the commonly used clinical atomization drug delivery is based on this principle. The atomized drugs will be absorbed by the human body. Not only that, but the improvement of modern atomization technology has also made the level of atomization higher and higher. For example, Smoore’s FEELM can achieve 1μm atomization, which means that the atomized smoke does not contain PM1- The particulate matter within the PM10 range will naturally not cause damage to the individual by the solid particulate matter. Definitely, the atomization material itself is also an important factor affecting the emission of harmful substances in e-cigarettes and the experience of e-cigarette consumption. The figure below shows the different stages of the atomization development of e-cigarette technology, from fiber rope, organic cotton, stainless steel mesh CCELL to Smoore’s FEELM.
The improvement is not only the improvement of the e-cigarette experience itself (picture left), but also the reduction of harmful substances released by e-cigarettes (picture right). For example, porous ceramics have higher heat conduction efficiency, which can reduce atomization. time.
Here comes the matter. We have already proved that electronic cigarettes are much less harmful than ordinary cigarettes, as shown in:
1. Ordinary cigarettes have huge harmful smoke tar, and electronic cigarettes do not have smoke tar
2. The nicotine content of ordinary cigarettes is fixed, which is difficult to eradicate. The nicotine of e-cigarettes is an added ingredient that can be adjusted to different concentrations
3. The burning of ordinary smoke will produce a large number of indecomposable solid particles such as PM2.5 attached to the throat, trachea, lungs and other parts, and continue to accumulate to cause harm to the human body. , And the electronic cigarette technology produces liquid particles that can be decomposed by the human body to absorb or discharge, basically no particle damage.
That is why e-cigarettes are used as a substitute for ordinary cigarettes. The advantage of this is that for those who cannot quit smoking, it can reduce the health damage caused by harmful substances such as tar in ordinary cigarettes; at the same time, the components of e-cigarettes are controllable. For example, the nicotine content can be continuously reduced, thereby reducing the patient’s dependence on nicotine, thereby achieving cessation of smoking. So it will be used to quit smoking.
