To understand whether vape juice expires or not, the first thing is to first know what vape juice is and its components. Vape juice is one of the essential parts of vaping. Vape juice is also known as e liquid, it is vaped by vapers. Vape juices come in different flavors and are produced by a large number of vape companies.

E liquid is made up of four components: vegetable glycerin, propylene glycol, nicotine and flavorings.

Vegetable glycerin

Vegetable glycerin, in short VG is a diluting agent. VG is used to change the consistency of e liquid, to make it thicker. It also helps in making e liquid more satisfying. Vegetable glycerin is made with vegetable plants such as soy, coconut oil or palm.

Propylene glycol

Propylene glycol or PG is a also diluent. It is responsible for giving the throat hit that vapers get from vaping. People who are chain smokers are mostly habitual of the throat hit. When they switch to vaping, PG provides them with a healthier alternative to the same throat hit.


Just like the name, flavorings are used to add some taste or flavor to the e liquid. When you buy an e liquid and it has strawberry or lime taste, it is because of the flavorings.

Do vape juice expire?

Vape juice does have an expiry date just like any other consumable item. Expiration date gives an estimate about the date when content will no longer be guaranteed to have the same quality as claimed.

Most of the e liquids have an expiration date of 1 to 2 years. The three important components, nicotine, VG and PG have a lifetime of around 2 years if they are kept under the correct conditions; in a cool, dark and dry place. But if these components are exposed to extreme heat or direct sunlight, they begin to break down sooner.

One of the reasons why people do vaping is the different flavors they can get. A major problem with expired vape juices is that their taste might either be stale or the flavor might have changed altogether after the expiration date.

Here again, it depends upon the producer and the flavor of e liquid. Some e liquids might have the same flavor even after 5 years while majority of them lose their original flavor in a time span of two years.

How to know if your vape juice expired?

If you do not know if your vape juice has expired or not, here are three ways to help you out:

  • Storage:  If you have stored your e liquid in a place, which has direct sunlight or extreme heat – chances are it will expired before the expiration date. If you store it in a cool, dark and dry place – it is good to use for 2 years.
  • Separation: If the components of the e liquid seem to have separated, it means the e liquid has expired. The denser components will sink on the bottom of the bottle.
  • Smell: By smelling the e liquid, you can know if your vape juice has expired or not. If the smell is aberrant, odd or seem to be a rotten smell – chances are your vape juice has expired.
