Many newcomers only consider "taste" and "brand" when choosing E-liquid (E-Juice), but when they buy it, they find that the effect is far from what they imagined. Knowing the composition and general working principle of e-liquid can not only help you avoid detours when choosing e-liquid, but also let you understand what is pumped into your lungs (more assured). IHAVE VAPING hopes to help more newcomers here.
E-liquid is mainly composed of four substances: "trace nicotine", "PG ( Propylene Glycol )", "VG ( Vegetable Glycerin )", and "flavoring agent & essence".
Trace nicotine
Also known as nicotine, it is the addictive substance of cigarettes. The trace amount of nicotine in e-liquid can ensure that smoking cravings are satisfied.
Pure nicotine is highly toxic, and the nicotine content in e-liquid is often expressed in mg/ml. Generally speaking, when purchasing e-liquid, you can choose 24mg/ml (very high concentration), 18mg/ml (high concentration), 12mg/ml (medium concentration), 6mg/ml (low concentration) or 0mg/ml (no nicotine) . The concentration of nicotine over 24mg/ml is very harmful to the body, so basically, no manufacturer has produced it, but customers can mix it by themselves (take it easy, this is life-threatening!)
Nicotine is the first reason for the "throat feeling" of e-cigarettes. The higher the nicotine concentration in the e-juice, the stronger the "throat hit", but at the same time, the taste of the e-juice will be reduced.
Many newcomers will ask: "What nicotine-concentration e-liquid do I need?" This question is difficult to answer, because everyone's smoking addiction and "throat-throat" needs are different, and everyone's frequency of vaping is also different. Moreover, different atomizer structures, atomizing core settings, and atomizer airflow size will affect the "throat feeling" and "lung's absorption efficiency of nicotine", resulting in different personal experiences. A pack of Huang Furong Wang a day before I smoked e-cigarettes, the nicotine concentration of 18mg/ml e-liquid is slightly higher for me. When you choose the nicotine concentration, it is recommended to use 12mg/ml first, and then "decrease and increase" in the future (the nicotine concentration of 12mg/ml is also recommended by foreign manufacturers, and this concentration is a good balance between "throat hit" and "e-juice" Taste”, that is, to satisfy your cravings without losing too much flavor of e-liquid).
In any case, nicotine is always a harmful substance to the human body, which is also the reason why many people criticize "e-cigarettes" as unhealthy. But compared with the more than 4,000 harmful substances produced by cigarette combustion, nicotine is relatively healthy. Want to truly quit smoking in a healthy way? Just don't smoke anything!
PG
It is a common drug and food additive, hygroscopic, slightly sweet, odorless, colorless, and transparent, and its fluidity is similar to that of water. The U.S. Food and Drug Administration (FDA) describes PG as "generally safe for humans."
As one of the basic components of e-liquid (carrying nicotine, flavorings & flavors), PG is mainly used to "carry most of the flavor of e-liquid" and produce "a small amount of mist" and "throat hit". If you like "big smoke", then the PG content of the oil you choose should not be too high.
Although PG is generally safe for the human body, a small number of people still experience side effects such as throat discomfort, phlegm, and allergies. These side effects are short-lived and mild, as long as you stop smoking or switch to a low-PG content e-juice (some e-juices are PG-free).
VG
It is a more common drug and food additive (generally used to make cakes, chocolates, and other sweets), very hygroscopic, sweeter than PG, odorless, colorless, and transparent, and its fluidity is similar to that of edible oil.
As one of the basic components of electronic cigarette oil (carrying nicotine and flavorings & flavors), VG is mainly used to generate "a lot of mist.
VG has no side effects on the human body (I have never heard of anyone allergic to chocolate...), but due to its viscous nature, it will slightly increase the difficulty of cleaning the atomizer.
If you see the oil that is viscous, it means that the VG content is high.
Flavors & Fragrances
Needless to say, the various flavors of e-juice are adjusted by flavoring agents. Flavoring agents and essences are easier to attach to PG (only relatively speaking, otherwise those pure VG e-liquids will be tasteless?). But it is worth noting that the higher the concentration of nicotine in the e-liquid, the less likely the flavors and fragrances are detected by the nose and mouth. Some flavors and flavors can also produce a "throat feeling", such as mint flavor...
There are thousands of e-liquid manufacturers, but qualified vapers (people who smoke e-cigarettes) still try to choose high-quality e-cigarettes. It is difficult to guarantee the safety of the flavorings & essences used in the production of e-liquid by those small workshops and black-hearted companies, and the taste is even more difficult to say.
caution
The same e-liquid may produce completely different personal experiences under different atomizers and settings.
Because e-liquid can be DIY, some manufacturers and vapers will add other things to it: water, vodka, sweeteners, etc...
On the whole, e-liquid is a relatively safe and low-harm substance, and regular products from regular manufacturers can be used with peace of mind.
According to the knowledge provided in this article, everyone will not be completely confused when choosing e-liquid.
To give a few examples
If you want a sweeter, smokey, "throat hit" that is strong: choose high VG, high nicotine, and a little mint-flavored e-liquid.
If you want a soft, moderate amount of mist: select e-liquids such as PG/VG, medium, and low nicotine.
If you want a layered flavor: choose a low-nicotine e-juice.
If you think life lacks passion: choose high PG, high nicotine, pure mint-flavored e-liquid.
