What is the composition of e-cigarette oil? E-cigarette oil is generally composed of five major types of raw materials, namely PG (propylene glycol), VG (vegetable glycerin also called glycerol), flavor, nicotine, and taste improving additives. Of course, different brands may also add some other substances.
So are the ingredients in these e-cigarette oils toxic? Let's take a look separately.
Nicotine
Nicotine is something that people think is harmful when mentioned. Many people only think that nicotine is highly toxic, permeable, and addictive. In fact, it is universal. Various eggplant plants, such as peppers, eggplants, tomatoes, etc., contain a certain amount of nicotine, and tobacco leaves are only among them. Kind of plant.
The nicotine in tobacco is addictive because the nicotine in tobacco is purified.
In fact, the harm of simple trace nicotine is very limited. There are also nicotine components in e-cigarettes, ranging from 1.5mg/ml (1/8 of the nicotine concentration of a cigarette) to 36mg/ml (3 times the concentration of a cigarette). . There are also e-cigarettes that do not contain nicotine.
So from the point of view of nicotine content, e-cigarette liquid is safe.
essence
E-cigarette flavors are generally edible, and the biggest risk of e-cigarette oil flavors is carbon fiber particles. At present, it is only possible to reduce the content of carbon fiber particles, but it is impossible to completely eliminate them. It should be pointed out that the carbon particles in cigarettes are much higher than the content of electronic cigarettes.
The potential risk of chemical synthetic flavor lies in the uncertainty of its use and ratio. Organic chemistry is not as highly accurate as inorganic chemistry. There are countless possibilities of combination in organic chemistry during the reaction process. No one knows whether a certain synthetic flavor will react with another flavor to produce unknown substances, and whether this unknown substance will decompose to produce other unknown substances or harmful substances under heating conditions. This is also the fundamental reason why various toxic substances can also be detected in the smoke of e-cigarettes.
Therefore, problems with the ratio of flavors are harmful to the human body. So if you want to buy e-cigarette oil, you must choose a formal one.
VG (Vegetable Glycerin is also called Glycerol)
This is actually what we call glycerin, but if the purity of glycerin itself is high enough, there will be basically no adverse reactions to healthy humans. The entry threshold for e-cigarette oil factories is too low, resulting in uneven quality of glycerin used.
Too much use of e-cigarettes will cause a feeling of thirst. In severe cases, oral ulcers will occur. This is because glycerin has a strong water absorption problem. This shortcoming needs to be solved by drinking more water.
It should be noted that after a large amount of glycerin enters the human body, the human blood sugar may increase, so it is best not to use electronic cigarettes for people with high blood sugar and diabetes! In addition, when choosing glycerin, try to choose better quality.
PG (Propylene Glycol)
Propylene glycol is used as a flavor dissolving agent in e-liquid. If glycerin is too viscous, it will make it difficult to dissolve the flavor, and propylene glycol is the dissolving medium. However, it should be noted that inhaling large amounts of propylene glycol can cause irritation to the respiratory tract (a bit like the throat sensation of nicotine). As a liquid, propylene glycol can volatilize with the respiratory system. As for the long-term effects of intermittent stimulation and then volatilization, there is still no conclusion in the medical field.
Taste improving additives
The taste-improving additives make it smoother when the user inhales, and this kind of thing is generally not dangerous. The taste of different production batches will also change. Various objective reasons, such as stirring, heating, waking up, etc., will affect the taste of e-liquid, just the same. More importantly, if you change the equipment and then pump this oil, the taste is definitely different.
