Does Vape Juice Have An Expiration Date?
Indeed, it does! All e-liquid has an expiration date, which should be printed on the bottle’s label or, sometimes, on the box it comes in.
So, where can you find the expiration date? If you buy your e-liquids from a reputable vaping store, you should see an expiration date, usually a year or two down the road, depending on how long the retailer has been storing them.
Why Does Vape Juice Expire?
The Medicine and Healthcare products Regulatory Agency, also known as the MHRA, mandates that e-liquid manufacturers display clear ingredient information.
You have to remember that e-liquid is made up of several components: PG, VG, flavourings, and nicotine solution. And these ingredients can spoil!
PG (propylene glycol) tends to be long-lasting, as it’s resistant to bacterial and fungal moulds and contains trace amounts of alcohol. VG (vegetable glycerin), on the other hand, is more prone to spoiling as it lacks the antimicrobial elements of PG.
And remember that VG is effectively a sugar syrup. Have you ever smelled a room where some sugar got spilt on the floor and left to rot? Yuck.
The flavour concentrate will spoil over time, and the amount of time will be determined by the PG/VG ratio of the flavouring. Finally, liquid nicotine solution can spoil over time from sunlight exposure and oxidation.
How Long Does Unopened Vape Juice Last?
You’ll be glad to hear that unopened bottles of nicotine-infused e-liquid tend to have a shelf life of around 1-2 years from the moment of production and sealing. Safely sealed, your vape juice shouldn’t be damaged by air exposure or oxidation.
Some variations depend on the nicotine content and nicotine type used in a given e-liquid. For example, nicotine salts don’t actually age faster, but you can taste subtle changes in the formula more clearly:
| E-Liquid Type | Lifespan of Sealed E-liquid |
| Nicotine-free vape juice | 2 years |
| Nicotine salts | 6 months to 1 year |
| Freebase nicotine vape juice | 1-2 years |
BUT! You still have a role to play, dear reader, in ensuring your sealed vape juice remains stable in storage. Keep these facts in mind:
E-liquid is best stored in a cool, dark place at a stable temperature.
Prolonged exposure to sunlight and heat results in degradation of the nicotine and VG within the bottle.
Exposure to intense cold can negatively impact the VG contents of your vape juice, resulting in separation, ‘gloopiness’ and wicking issues.
You ever tried soaking molasses into cotton? Weird if you have, honestly. But that’s a similar experience to trying to get near-frozen vape juice into a coil.
How Long Does Opened Vape Juice Last?
Once the bottle’s open, that’s the starting pistol! THE CLOCK IS TICKING, GET PUFFING!
I jest, I jest; there’s no need to panic. Opened bottles of vape juice will usually last around half as long as sealed bottles. And it’s very unusual for someone to take more than 3-6 months to finish off some vape liquid.
| E-Liquid Type | Lifespan of Opened E-liquid |
| Nicotine-free vape juice | 1 year |
| Nicotine salts | 3 to 6 months |
| Freebase nicotine vape juice | 6 to 12 months |
It’s important to note that expired nicotine will not actually make you sick; it’s just less effective and satisfying. If you look into a clear bottle of very old nicotine liquid, it may look darker than a newer bottle. That’s partly because of the nicotine’s oxidation over time.
You can still get a nicotine ‘hit’ from expired nicotine solution, but it’s likely to be weaker and might have a less pleasant taste as the flavouring sugars begin to rot.
Do Disposable Vapes Expire?
Disposable vapes do indeed expire. It’s not like the plastic casing of a Lost Mary BM600 provides any greater protection to the e-liquid within than a dark juice bottle will.
So, your current disposable vape’s nic salt contents will have roughly the same shelf life as an opened bottle. This is why so many of them come in sealed plastic wraps! The less air exposure your e-liquid goes through, the longer it lasts.
But you also need to consider the battery. Even unused, the power cell will gradually self-discharge. While it’s unusual, you wouldn’t be the first person unable to enjoy all their disposable vape juice because the battery died before the last puff!
How About Prefilled Pods? Do They Expire Too?
You can guess the answer if you’ve been reading closely so far.
Yes, prefilled vape pods expire as well. ALL E-LIQUID SPOILS! That’s kind of the main crux of this FAQ.
Prefilled pods ordinarily last a similar amount of time as e-liquid bottles, as they are usually sold in a sealed format, such as blister packs or stickers.
Once the pod is unsealed, your timeframe is relatively ample, similar to that experienced with unsealed e-liquid bottles.
Ideally, a prefilled vape pod should be unsealed within 1-2 years of purchase and, once opened, vaped within 6-12 months. And if you can make an open e-liquid pod last 12 months, call me. Because that’s fascinating.
As usual, keeping the fluid-filled pod away from sunlight and from extreme temperatures will ensure long-lasting vape juice in the prefilled pod.
Can Vaping Old Vape Juice Make You Sick?
There is no evidence or study suggesting that expired e-liquid will not make you sick, but you might gag if the taste is bad enough!
As mentioned previously, expired nicotine isn’t any more harmful than in-date nicotine. While VG and flavourings can spoil when left to breathe and soak in some poolside sunrays, this just results in vape juice that’s either discoloured, less sweet than usual, or a little musky.
Distasteful? Certainly. Dangerous? Not to anyone’s knowledge, and we’ve been vaping for over 10 years now.
CAUTION: We aren’t telling you to go caution-to-the-wind buck wild, though. E-liquid containing nicotine should always be handled very carefully, as nicotine is not only an addictive substance but can lead to nausea if orally ingested.
How To Tell if Your Vape Juice Is Expired?
If you’re feeling a bit iffy about some vape juice and are concerned it may have spoiled, there are a few little things you can do to check.
Separated Ingredients
It’s not unusual for e-liquid, left untouched for some time, to begin separating as the heavy liquids sink to the bottom of the container. Usually, a firm shake is all it takes to recombine all the juice elements. It’s a lot like adding nic shots to shortfills if you’ve ever done that before!
If, even after a few good shakes, the liquids in the bottle still don’t seem to be mixing and emulsifying, then that’s a good indication that the e-liquid isn’t right. If it’s a bottle you’ve bought recently, show it to the vape retailer you purchased it from, and they’ll likely sort you out with a fresher bottle.
Weird Smell
You can always rely on the sniff test in almost all matters of tasty consumables of questionable freshness. Go with your nose; you already know what caramel vanilla should smell like. Are you getting sour, musky or acidic notes from what should be a dessert symphony?
Sounds like a bad batch to me, brother!
Too Much Sun
Ignoring all our excellent advice, have you left your vape juice in a sunny window for a few days? Take a look at the juice; if it seems darker than you remembered, UV exposure will have sped up the oxidation process. This usually results in weaker nicotine and weaker flavour.
How To Avoid Shortening the Shelf-Life of Your Vape Juice?
Keep It Out of Heat and Direct Sunlight
Who doesn’t love letting their hair down in the sunshine? But be careful, because those UV rays you relish won’t exactly make your e-liquid beach-ready!
Quite the opposite—if you leave your bottle of vape juice exposed to the sun for too long it will degrade its ingredients and cause it to go bad.
When VG is exposed to temperatures above 250 fahrenheit, the components within the liquid will separate and fail to recombine even at lower temperatures. And when PG is under the same conditions, it can also become unstable and lose its flavour.
This also applies to heat in general, so don’t leave that bottle of e-juice next to the stove or on top of the car dashboard!
Don’t Expose It to Too Much Air
We all know about air-flow and how essential it is to get a good vape. But forgetting to screw the lid back on your bottle of vape juice can have less than pleasant consequences.
Though air is actually made up of a plethora of different chemicals, it’s the oxygen that can cause problems for the longevity of your e-liquid.
When oxygen reacts with nicotine it produces cotinine. This is called an “oxidation” process which essentially means the loss of two hydrogen atoms and the gain of one oxygen atom. Put simply, too much exposure to oxygen will impair the flavour, and reduce the nicotine content of your vape juice.
Of course, this isn’t entirely avoidable, but the effects are only really noticeable after long periods of exposure. So stay vigilant!
Store in a Cool, Dark, Place
We’ve already discussed how heat, sunlight, and air are kryptonite to a good vape, so beyond that, just ensure you keep your e-liquid stored in a cool, dark place—like a bag of potatoes!
Tip: Let’s bust the myth that prolonged storage causes e-liquid to go bad. In actual fact, storing your vape juice in the right conditions can, similar to wine, enhance its flavour. This is called steeping.
The Last Drop
So, does vape juice expire? Absolutely — but it’s not the end of the world. As long as you store your bottles properly and keep an eye (and nose) out for signs of spoilage, you can enjoy your favourite flavours for months, even years. Just remember: keep it cool, keep it dark, and when in doubt, give it a sniff.
