What’s in E-Juice, exactly?

Certain criticisms are often leveled at e-cigarette advocates – that there’s too much unknown with e-cigarettes, that consumers aren’t aware of what they’re putting into their bodies. In actuality, however, e-juice recipes are quite simple. Unlike traditional cigarettes, you won’t find over 4,000 ingredients in each puff of an e-cig. Three ingredients comprise most e-liquids: nicotine, flavoring, and a diluent. The vapor that’s exhaled is even simpler: it consists principally of traces of the particles used for flavoring and water.

The most commonly used diluent in e-cigarettes is propylene glycol. While this product may seem foreign to consumable products at first, it’s important to note that it’s a common ingredient in medicine inhalers, generally as a solvent in cosmetic products and even food. While some are sensitive to the product, it’s benign for most, as its toxicity is quite low. Because it absorbs moisture very well it can cause dry mouth with prolonged use, but vapers will note a stronger ‘throat hit,’ making the physical e-cig experience closer to that of an analog cigarette.

Vegetable glycerin is used for the same purpose for some brands. It’s viscosity makes it better for non-tank personal vaporizers, but the throat hit produced is typically weaker. It’s also naturally sweet, so vegetable glycerin based liquids can have a taste that’s harder to detect than in their propylene glycol counterparts.

Many e-liquid companies offer mixtures of the two, for those who fix their own e-juice and fill their own cartomizers.


The most recognizable active ingredient in analog cigarettes, nicotine is a stimulant that affects the central nervous system. Reliable e-cigarette liquid uses pharmaceutical-grade nicotine, ensuring consumer safety and reliability. The global nicotine supply is derived from the cultivation of the tobacco plant in a number of regions. Many e-cigarette providers, such as Nuvocig, offer liquids at various nicotine strength concentrations, allowing you to customize your vaping experience based on the types of cigarettes you buy (bought!). Match your nicotine levels to full-flavor, light, or unfiltered cigarettes, and if your goal is to butt the habit completely there are even nicotine-free options available.


E-cig flavoursFlavoring for e-cigarettes can come from a number of products. The most common are essential oils and extracts. Coffee, vanilla, cherries, chocolate , peppermint, and peach are common flavors, but shops, with storefronts online and in brick and mortar, have begun to sell various non-traditional flavors of all sorts. Nuvocig, in particular, boasts a wide variety of flavors including champagne, whiskey, mango and many others, in addition to the standard menthol and tobacco offerings. Flavor juices produce the faint scent of their flavor as the smoker exhales, but the particles in the air are nowhere near as powerful as and are far less harmful than smoke produced by tobacco cigarettes.

It’s really that simple.

With fewer questionable chemicals in e-liquids than in analog cigarettes, there’s little question that it’s a simpler and safer alternative. It’s true that propylene glycol can cause allergic reactions but this is true for many other products and does not mean that it should be feared or avoided for consumption off-hand. With over 4,000 various chemicals in analog cigarettes, the ingredients in e-juices comprise only 0.075% the number of ingredients in traditional tobacco products.
