Cannabis vapes offer a lot of conveniences that flower does not, but that doesn’t mean there isn’t a bit of maintenance required to ensure your vape remains flavorful and potent. For example, your vape juice may not dry out the way that flower can, but it does have a shelf life, and there are things you can do to ensure it lasts longer and you don’t waste your money. 

But how long does e-juice last, and can you use expired vape juice without incurring any health risks? It’s essential to know these answers if you’re going to choose this method of cannabis consumption. Check out this vape juice expiration guide to ensure you’re up-to-date on all of the necessary information. 


What’s in Vape Juice?

The recipe for a high-quality THC vape juice is not complicated, but it’s also not simply a cannabis concentrate in a cartridge. To ensure juice vaporizes properly and offers plenty of terpene-loaded flavor, a few other ingredients must be included in the mix. 


Water is used in THC vape juice to provide a more desirable consistency and to help the juice vaporize more efficiently.

Propylene Glycol or Vegetable Glycerin

Propylene glycol and vegetable glycerin are thickening agents that have no smell, color, or taste. They are used in a variety of foods and are considered “generally safe” by the FDA. These agents are used in THC vape juice to improve flavor and provide a smoother hit.  

Cannabis Concentrate

The most important ingredient in any THC vape juice is the one containing the THC itself. That would be the cannabis concentrate, which can come in various forms. 

Cannabis concentrates are made by extracting the desirable components of cannabis flower (like THC and CBD) and concentrating them to be incredibly potent and flavorful. This is done through several methods, each offering unique advantages.

Live resin is one of the more popular types of concentrate in a THC vape cart. Live resin is created by flash-freezing cannabis flower right after it has been harvested. This helps retain the maximum amount of terpenes during the extraction process, so the flavor profile of the resulting concentrate is second to none. 


How Long Does a Bottle of Vape Juice Last?

Some people may enjoy cannabis frequently enough that they don’t have to worry about vape juice expiration. Still, if you’re someone who likes to savor their cannabinoids, you’ll want to know just how long you’ve got before your product has started to degrade in quality. So just how long is e-juice good for

Vape Juice Shelf Life

Typically, you can expect vape juice expiration within about a year after the product has been manufactured. 

Keep in mind that this doesn’t mean a year after you’ve purchased it, as the THC vape juice may have been sitting around for some time before you bought it. For this reason, you’ll want to find the manufacture date on the bottle so you’ve got a clear idea of when it will expire. 

In some instances, your THC vape juice can last far longer than a year, which you’ll likely see right on the juice’s expiration date. However, even without the expiration date, there are signs you can look for to determine whether you’re working with expired vape juice.

Where is the Expiration Date on Vape Juice?

You should be able to easily find an expiration date on the label of your vape juice. If you don’t, it may be a good idea to note the date of purchase so you can at least have a rough idea of when the product will go bad. And if all else fails, keep an eye out for the signs of expired vape juice.


Signs of Expired Vape Juice

Any company you choose to purchase your THC vape juice from should be reputable and trusted to properly label their products. Still, it’s always wise to choose firsthand observation over brand loyalty when it comes to anything you put into your body. To sharpen your firsthand observation skills, look at these common signs of vape juice expiration

Color Change

The oxidation process will eventually cause your THC vape juice to change colors from clear amber to darker and cloudy. As oxidation continues, the liquid will eventually become a dark brown and finally wind up black. 

Change in Consistency

Along with the color change, you’ll find that expired vape juice goes from a relatively loose liquid that shifts around when you move the cartridge to something gunkier and denser. A good look at that will likely make you second guess giving your vape a quick try to see if it’s still good.

Altered or Weakened Flavor 

The terpenes that provide your THC vape juice with its incredible flavor profile will begin to break down over time, resulting in your hits tasting weaker and less satisfying. As the breakdown progresses, the flavor will go from a weaker version of its former self to something more unpleasant. 

Decreased Potency

In the same way that your THC vape juice’s terpenes will begin to break down, so will the powerful cannabinoids it contains. This means that a good hit from the contents of your THC vape juice bottle won’t open the doors of perception quite as easily as it once did. 

This lack of potency may not be immediately evident to you, but if you’re finding that it takes a few more hits to feel the effects, the odds are that your THC vape juice has expired.


Can You Use Expired Vape Juice?

It can be frustrating to bust out your THC vape for a quick sesh only to find that the product has gone bad and you’ve got nothing to work with. Naturally, you’ll likely consider whether to use it anyway. After all, if it only results in worse flavor and weaker potency, what’s the big deal? 

There is no need to panic, as the issue of expired vape juice is not as critical as, for instance, consuming expired meat, which can lead to immediate hospitalization. While expired vape juice does not pose immediate health risks, it is still advisable to refrain from vaping it.

There is some potential for your THC vape juice to develop mold. You do not want to inhale mold, as it can potentially cause lung issues. You’ll also have a far less pleasant experience with your vape, mold or not, due to the loss of potency and flavor. 


How to Make Vape Juice Last Longer

In the same way you properly store food to prolong its lifespan, you can also store your THC vape juice in optimal conditions to keep it from expiring. 

Heat, light, and moisture are the three main things you want to keep your THC vape juice protected from, as they are the main culprits when it comes to its degradation. Take your cart off the vape battery when it’s not in use, and store it in a cool, dry, dark place to keep it in good condition. 


Fresh THC Vape Juice is the Best THC Vape Juice

Vape juice generally expires within about a year of its manufacturing date. After expiration, it can become darker, gunkier, less flavorful, and less potent. It’s not inherently dangerous to use expired juice, but it’s also far from optimal. And if you want to keep it fresh for as long as possible, store it somewhere cool, dry, and dark when it’s not in use.
