What is Ejuice?

All vaping, no matter the size or look of the vape device, requires the presence of e-liquid to make vapor. Vape juice comes in a plethora of flavors, different viscosities, and wide array of nicotine strengths.

Vape juice is the liquid used in electronic Vaporizers/E-cigarettes that gets turned into vapor.

 It’s also referred to as:

  • E-liquid
  • E-juice (or ejuice)
  • Vaping liquid
  • E-cig juice

What is in vape juice?


E-liquid is made out of some essential and some optional ingredients. These ingredients can be categorized into base liquids (PG/VG), flavorings and sweeteners, and nicotine.

The base of vape juice contains propylene glycol and vegetable glycerine, otherwise known as PG and VG. Some juices come in 100% VG, but this is not very common—just as 100% PG is also uncommon. VG and PG also form the ratio you will usually find on an e-liquid bottle, like 70/30 or 50/50 with VG typically being first.


Flavor concentrates are water-soluble and usually made by companies that manufacture food flavorings and/or fragrances. They range from tobaccos to fruits to chocolate glazed donuts—and everything in between. Many of the commercial e-juices will also contain sweeteners, with the most common of these being sucralose.

Does vape juice go bad and expire?

Technically yes, e-liquid can go bad. But it’s not the same as food going bad. Vape juice is very shelf stable. It might even change color and turn brown with time, but this doesn’t mean that it has expired. Generally speaking, e-liquid lasts as long as its first ingredient to “expire.” As a rule of thumb, that will be up to two years from its date of manufacture.

E-liquid does not like heat, sunlight, and oxygen—how long it lasts will depend on how successful you are in avoiding them. Don’t run to store all your bottles in the fridge though! Storing your e-liquid firmly closed in a dry and cool cupboard is the best way you can ensure that your favorite juice will last as long as possible.

 Some e-liquid bottles will have an expiration date on them, some won’t. But based on the FDA’s rules on consumable products, only infant formula is required to have an expiration date. “Best by” and “expires on” dates are up to the discretion of the manufacturer.

 E-liquid pricing: what should it cost?

Vape juice pricing is all over the map. You might have to pay upwards of $20 for 30ml of premium juice but the same money may get you 120 mL of a non-premium e-liquid. While most of the times you do get what you pay for, this doesn’t mean that there aren’t some overpriced vape juices around, or that low priced juices can’t be of good quality.

E-liquid usually comes in three bottle sizes:  30ml, 60ml and 100ml/120 ml. Other sizes exist but are not that common.

In general, a 30 ml bottle should cost you between $10 and $20.  You can save some money if you go for larger quantities. A 60ml bottle of vape juice will usually sell between $20 and $30, while a 100ml/120ml bottle will set you back between $35 and $45.


​​What happens if you accidentally swallow vape juice?

Swallowing a bit of nicotine-free vape juice is not going to cause any adverse side-effects. If your vape juice has nicotine in it, that’s different… though not automatically a concern. The dose makes the poison. If you somehow manage to swallow a lot of juice, no matter the strength, call poison control.

Does vape juice stain fabrics?

In most cases, no. Most stains from e-liquid will go away after a wash. You can also apply some dish-washing liquid on the stain and rub it with a fine cloth to be extra safe. That said, some e-liquid may contain artificial coloring which could stain your clothes. These will usually have brighter colors and are easy to recognize.

How to clean up e-juice spill?

If it’s just a little bit, wiping it with some kitchen paper will suffice. If you spill a whole bottle, and especially if you have kids or pets around (especially cats), go the extra mile and use some of your surface cleaner. Nicotine does penetrate the skin, so wear gloves while cleaning up.

How should vape juice be stored?

Preferably firmly closed in a cool and dry cupboard, away from direct sunlight. If your bottles are dark tinted, this should mitigate any issues.

Is vape juice oil?

Νο, e-liquid is NOT oil. Some vape juice may contain trace amounts of natural oils that come from fruit, tobacco, or other extracts, but these are rarities and are not in a large enough quantity to change the miscibility of vape juice in water. Although vape juice may appear to be oil like, it’s not an oil. The oils proper for vaping have to do with cannabis and not vape juice.
