Practically speaking, the harmlessness of e-cigarettes is false, but it is very small, much less harmful than ordinary cigarettes. In fact, e-cigarette is a kind of non-combustible e-cigarette, also called "atomized e-cigarette". It consists of a shell, a cigarette holder, a dust filter, a spice box, a light-emitting diode, a power supply and a cigarette cap. It does not burn, only contains purified nicotine, does not contain tar, does not contain chemicals that cause respiratory and cardiovascular diseases in ordinary cigarettes, and removes other carcinogens in ordinary cigarettes. Its efficacy is similar to that of ordinary cigarettes, which can refresh the mind, satisfy the craving, make smokers feel happy and relaxed, and at the same time have the function of quitting smoking. The essential difference between "electronic cigarette" and ordinary cigarette is that it contains no tar harmful to human body and no carcinogen; Do not burn, and do not produce harmful chemicals after burning; There is no harm to others and environmental pollution caused by "second-hand smoke"; There is no fire hazard, and it can be used in places where smoking and fire are prohibited. Non-toxic, non-combustible and pollution-free, it is a good substitute for cigarettes.
Believe me, you all know the harm of ordinary cigarettes.

Experiments show that people may inhale many other undiscovered toxic compounds besides nicotine when using e-cigarettes. At the same time, the second-hand smoke produced by e-cigarettes may also be harmful to health. E-cigarettes also release inhalable liquid fine particles and ultrafine particles, nicotine and carcinogens into the room. Because e-cigarettes do not produce smoke, it is easier to mislead consumers and make them have the wrong idea of safety and health. The nicotine content of some electronic cigarettes is too high, which may be much more harmful than ordinary cigarettes. Although e-cigarettes contain no tar, the nicotine in them is not harmless. Simply inhaling nicotine can also pose health risks. Nicotine itself is not a carcinogen, but it can act as a "tumor starter". In addition, there is sufficient evidence that exposure to nicotine in fetuses and adolescents will have long-term adverse consequences on brain development.

Because e-cigarettes do not burn to produce tar and carbon dioxide, it is certain that e-cigarettes are harmless to the environment. E-cigarettes are less harmful to the environment than traditional cigarettes, especially second-hand smoke. E-cigarettes do not have the problems of second-hand smoke and environmental pollution. E-cigarette atomizes the liquid of e-cigarette into smoke through its atomizer, thus simulating the effect of cigarette. To detect whether e-cigarettes are harmful to human body, it is essential to detect whether e-cigarette liquid components in e-cigarettes are harmful to human body. E-cigarette liquid is mainly composed of cigarette liquid base material and cigarette liquid perfume. At present, there are three kinds of cigarette liquid base materials for making electronic cigarette liquid: propylene glycol (PG), glycerol (VG) and polyethylene glycol (PG400). Propylene glycol (PG), glycerol (VG) and polyethylene glycol (PG400) are widely used as moisture absorbent, emulsifier, antifreeze, softener, sweetener, lubricant and solvent in food, medicine and cosmetics industries. If the tobacco liquid base and tobacco liquid perfume in the used electronic cigarette liquid are made of high-quality materials of medical grade or food grade according to the technological conditions of medical grade or food grade, then the use of this electronic cigarette should be safe and harmless to human body.
These are the opinions of several experts consulted by Bian Xiao on whether e-cigarettes are harmful. Bian Xiao believes that if you want to quit smoking, e-cigarettes can be used as an auxiliary tool to help you reduce the harm caused by traditional cigarettes; And if you are a non-smoker, it is recommended not to try e-cigarettes easily, because e-cigarettes are not completely harmless.
