Vaping emerged in the early 2000s, initially embraced by nicotine smokers as an exciting new alternative to cigarettes. Today, vaping has become a worldwide pastime, available to smokers of nicotine, cannabis, medicinal herbs, and even oxygen! 

Vape juice is now available in virtually every flavor, and can be enjoyed using a huge range of batteries, making vaping one of the most versatile methods of consuming nicotine. 

While vaping is already an established mainstream hobby, many consumers still aren’t sure what exactly is in their vape juice. Ultimately, this simple guide covers everything you need to know about vape flavors and what’s inside your juice. 

What Is Vape Juice/E-Liquid?

Vape juice, commonly referred to as e-liquid, comprises 90% vegetable glycerine (a plant-based liquid-alcohol) or propylene glycol (liquid alcohol), depending on the preference of the manufacturer. Without producing vapor on its own, the VG/PG must be diluted with a small amount of water. The final 10% of a typical vape juice formula will include nicotine and commonly food-grade flavorings. Not to mention, nicotine content will vary depending on the desired potency. 

Is E-Liquid Safe to Inhale?

The debate surrounding vaping has centered almost entirely around its safety, with opponents of the trend citing possible respiratory complications resulting from inhaling vape juice. 

That said, the studies have not been in-depth nor representative of the adverse effects of vape juice. Luckily, despite a few reports of health issues possibly aggravated by consuming black-market e-juices, both vegetable glycerine and propylene glycol are deemed safe by the FDA and considered safe* to inhale in vapor form. 

*Note: While both common e-juice bases are considered safe, some individuals may experience mild allergic reactions to propylene glycol, so vegetable glycerine may be safer for general use. 

Does Vape Juice Expire?

Both vegetable glycerine and propylene glycol have a shelf-life of approximately two years. Still, added flavor and nicotine can cause premature oxidation, reducing the potency of the juice. 


Keeping your e-liquid in a cool, dark place will help to slow aging and keep your liquid fresh for longer. If you notice that your e-liquid has changed colors, developed a smell, separated, or formed crystals, your juice is likely expiring. 

How Do Vape Juices Get Their Flavor?

To ensure that vape juices are safe for human consumption, vape manufacturers add food grade flavor concentrates to their vape juices. The flavored concentrates used in e-liquids are the same as those used in candy, soda, baked goods, and virtually every other processed food item found on market shelves. Check a few things in your pantry, and we can almost guarantee you’ll find at least one mention of ‘natural and artificial flavorings’ on their ingredient lists. 

Some concentrates are pre-mixed to smell or taste like a naturally occurring flavor, such as mint. That said, mixologists must formulate a blend of various concentrates for most flavor profiles. Mixologists spend years perfecting the perfect vape flavors to introduce to their customers, going through hundreds of formulas to find the ideal blend.

Mint is a natural flavor like peppermint, spearmint, etc. Both mint and menthol can be combined with other flavors.
