Nicotine Liquid (E-Liquid) for the Electric Cigarette

Nicotine liquid, also known as e-liquid or e-juice, is a liquid mixture for the electric cigarette. Nicotine liquid comes in a variety of flavors and a few basic nicotine levels.
Flavors of Nicotine Liquid
From the many nicotine liquid flavors offered by different manufacturers, two seem to be more popular: tobacco and mint. These two flavors have different names and slightly different tastes depending on the brand—names like Original Tobacco, Cured Tobacco, or Arctic Mint may be names for the same flavor or variants of the flavor.
There are nicotine liquid flavors made to taste like those of traditional cigarettes, for example, Marlboro, Camel, Winston, or Kent. The most common of those is Marlboro.
Smokers using the electric cigarette have a better choice of flavors than those who smoke traditional cigarettes. While it is rare for traditional cigarettes to have flavors of coffee, vanilla, strawberry, or chocolate, most nicotine liquid and electric cigarette makers and sellers offer those flavors.
Nicotine Liquid: What Is It Made of?
All main ingredients in nicotine liquid are food products generally considered as safe. There are two common main ingredients in it—propylene glycol and nicotine. Nicotine liquid can be 80 to 90% propylene glycol and 0 to 6% nicotine. Other less common ingredients are menthol—for the mint flavor, glycerol, and even pure water that can be about 10% of the solution.
