Most vapers have e-liquids stored at home for a long time. Are they still good for consumption? It is a question comes into their heads. With this article we hope to answer some of those questions, let’s get to it!


The answer is yes! All e-liquids have an expiration date but not all brands show it on their labels. Although both propylene glycol (PG) and vegetable glycerin (VG) are why the expiration date for e-liquids is 1-2 years, most of the changes in e-liquids are due to the oxidation of the nicotine and the degradation of the flavorings. Generally, older e-liquids will have less nicotine and weaker tastes. The effects of aging will vary from e-liquid to e-liquid.


There are many things that can happen to your e-liquid as it ages:

Smells and Tastes: E-liquids should taste and smell good when the bottles are fresh. However, flavors degrade over time causing them to change taste or lose aspects of a profile entirely. If a e-liquid doesn’t taste remotely like what you remember it being the flavors have gone bad and it is time to change it for a new one.

Color Changes: E-liquids will darken over time, especially e-liquids with nicotine, that is a normal reaction. Nicotine goes through a process called oxidation in which it chemically reacts with oxygen and changes form. However, if a e-liquid starts looking much darker than it originally was or starts turning colors that aren’t yellow and brown it is probably time to replace your e-liquid.

Separation: E-liquids are made up of different components. Sometimes, its ingredients begin to separate. Some separation is normal, that’s why the labels on many bottles say “SHAKE WELL”. However, when e-liquid is too old, it may not come together no matter how much it is shaken. There may also be crystallized flavors or debris that doesn’t dissolve with heat or mixing. At that point, vaping the e-liquid would be a risk not worth taking.

Nicotine Content: Because nicotine degrades over time, the amount of nicotine in the e-liquid will decrease over time as well. In addition to tasting bad, the expired e-liquid may not even satisfy your nicotine cravings.

Thickness: Generally, the e-liquid that has become much thicker or runnier than it originally was has gone bad. Not only could it be unpleasant to vape, it may also ruin your coils or leak out your tank.


All e-liquids will expire. There are several factors that can affect how fast any e-liquid will expire. First of all, nicsalts degrade more slowly than freebase nicotine does. This is due to their chemical nature as a salt rather than a base. However, e-liquids with no nicotine do not have to worry about nicotine degrading at all.

The flavor of the e-liquid will also affect how fast the e-liquid goes bad. Some flavors degrade faster than other flavors. Generally, fruit and floral flavors lose their potency and change before complex flavors like dough or custard do. This may lead to changes in the flavor profiles which, while not strictly unpleasant, can be disappointing. While nicotine type and flavor may not be something you have full control over, you can take steps to make any e-liquid last longer. Heat, agitation, light and exposure to air can all make your e-liquid degrade faster.

So if you want to preserve your e-liquid:
1. Keep it in a cool, dark place away from sunlight.
2. Don’t shake or move the bottles unnecessarily.
3. Open the bottles only when needed.


Yes! Steeping is a slight acceleration of the same aging processes to make e-liquid taste better or to make e-liquids more uniform. It is like letting a fruit ripen, some ripening can make it taste great, too much and you will end up with rotten fruit. Steeping e-liquids can reduce the lifespan of e-liquids as well.


There is no reason why e-liquid looks bad outside a tank and not inside a tank. Since tanks are usually heated and transported, tanks are the perfect conditions for e-liquid to age quickly.


Realistically, a hit or two will probably not kill you – that is how many vapers noticed there was something strange about their e-liquid in the first place. However, there have been no studies done on the safety of expired e-liquids. It is unclear if vaping expired e-liquid can be harmful or what could happen if you decided to vape a lot of expired e-liquid. If you have found this article, wondering if your e-liquid is safe to vape, we do not recommend it. The main degradation of e-liquids is with the nicotine and flavoring. So you would most likely be vaping something that tastes off and doesn’t satisfy any nicotine cravings. There is very little reason to try that when you can pick up a new bottle.
