Those who want to use electronic cigarettes often wonder what they will inhale into their lungs instead of the cigarette smoke they're tired of. However, vaporization technology is complex. Therefore, beginners often wonder what the two most common e-liquid bases mean. **PG liquid** stands for Propylene Glycol, while **VG liquid** stands for Vegetable Glycerin. E-liquids are fundamentally composed of four ingredients: PG or VG base liquid, water, nicotine, and flavorings. Both PG and VG liquids are non-toxic organic compounds and are also used in the food industry, so there's no harm in consuming them.
What is PG Liquid?
**PG liquid** is more popular compared to VG liquid because it's more fluid and more easily absorbed by the cotton in the atomizer. Due to the lower viscosity of PG liquids, atomizer coils wear out slower, and there is less heating difficulty. This results in better performance from the electronic cigarette. Moreover, since propylene glycol is a tasteless substance, it doesn't affect the e-liquid flavor. As it's a strong humectant, it can cause throat dryness with prolonged use. Therefore, it's necessary to consume this liquid with water. PG liquid provides a throat hit similar to, or even stronger than, that of a tobacco cigarette. However, PG liquid can cause allergic reactions in some users. These effects can range from a tingling sensation in the throat to irritation in different parts of the body. Those who experience such allergic issues after using PG liquid should stop using it and switch to VG liquid.
What is VG Liquid?
**Vegetable glycerin, or VG liquid**, is a thicker liquid solution compared to PG liquid. VG liquid has a slightly sweet taste when used alone. This makes it difficult to distinguish the flavors of other aromas when preparing e-liquid. However, users of VG liquid have also reported issues such as throat dryness or phlegm. VG users experience less throat hit. But, VG-based liquids produce significantly more vapor. Furthermore, it doesn't cause as many allergic reactions as PG liquid. For those seeking a taste similar to cigarettes, it's recommended to start with PG liquid and then transition to VG liquid.
