WHAT IS IN E-LIQUID

Just to clear the air, vaping is not smoking.

But the next issue is what is in that liquid that is being atomized into vapor?

Here is the scoop!

e-Liquid or e-Juice is normally made up of up to 5 ingredients (not main ingredients with a giant list of other stuff) :

VG (Vegetable Glycerin) The Base makes up 80-90% of e-liquid and is composed of 100% V...G or a mix with PG. Common ratios are 100% VG, 50/50 PG/VG, and 80/20 PG/VG. A higher VG mix e-liquid will produce thicker clouds of vapor. It is widely used in all types of food and personal care products like toothpaste. http://en.wikipedia.org/wiki/Glycerol

PG (Propylene glycol) Commonly mixed with VG as the base for e-liquid. This is a solvent that’s used in all sorts of things. Along with being a solvent, its mainly known for its use in fog machines. However PG can dry out your throat and even cause mild allergic reactions in some users. If you have any issues with PG, just use a 100% VG e-liquid. http://en.wikipedia.org/wiki/Propylene_glycol

Flavor 10%-20%. All the e-liquid I’ve seen uses Food grade flavorings originally intended for baking or candy making. Here is an excerpt from the LorAnn website: “All of our materials are food grade (where applicable) and adhere to standards set down in the USP, NF or FCC (U.S.Pharmacopoeia, National Formulary, and Food Chemical Codex).”

Nicotine 0%-2.4% depending on strength. Any large supplier of e-juice is using pharmaceutical grade pure nicotine.
Distilled water is sometimes used to dilute if needed.

There you go! From as little as 2 ingredients (VG and flavor) to as many as 5, and theories on nicotine ingestion non withstanding, all used regularly in food products.

Something to remember is what e-liquid doesn’t contain: the 4000+ chemicals in a cigarette.
