E-liquid can vary depending on the flavor, nicotine concentration, and composition; however, they all usually have the same basic ingredients: nicotine, propylene glycol (PG), flavoring, and vegetable glycerin (VG).
Most e-liquids are made from a PG/VG blend, which consists of varying levels of propylene glycol and vegetable glycerin. PG and VG are not oils; therefore, inhaling them is not known to cause conditions caused by inhaling oils, such as lipoid pneumonia. PG and VG are considered sugar alcohols and are included in many consumable products as an additive or preservative, including food or medication. Vape e-liquid is made from these liquids in combination with nicotine synthesized in a laboratory setting and a flavoring.
PG is less thick than VG and is used to produce a “throat hit, also known as “the burning” sensation that smokers feel in the throat when smoking a cigarette. PG also tends to have more flavor than VG based liquids. VG is derived from vegetable oil and is considered vegetarian. VG produces a smoother hit and is used to create vapor clouds; however, e-liquid that is high in VG can cause the coil to clog faster.
Most individuals using refillable devices use a 70/30 PG/VG mixture; however, there are many different variations including 75/25 PG/VG, 50/50 VG/PG, 70 VG/PG, and Max VG (close to 100% VG). If you are looking for more of a throat hit that has fewer clouds and will be less noticeable, then a higher PG e-liquid is for you; however, if you prefer a sweeter, smoother hit with thicker clouds, then a higher VG content may be better for you. ALLO pods typically have 50/50 ratio of PG/VG, giving you an even balance between flavor, smoothness, and clouds.
Some individuals may have a sensitivity or allergy to PG. It is normal to experience a dry mouth, increased level of thirst, and irritated throat when you first start vaping. If you are a beginner vaper, then check out our blog post with helpful hints on easing the transition. Normally the amounts of PG that are in food or medication are not enough to cause an allergic reaction; however, concentrations are higher in e-liquid, so if you notice that your tongue has any swelling or you have trouble breathing, then stop vaping to see if it improves. People can be allergic to nicotine as well. If you were previously a smoker, then you likely would know if this was the case.
