Vape juice doesn’t necessarily stay suitable for use indefinitely. Even properly stored bottles may change over time. You need to recognize the signs of bad juice. This can help you determine when to replace it.

Beware of these signs:

The color has changed significantly

Certain e-liquids will naturally darken over time due to oxidation. Especially nicotine e-liquids. A gradual color change does not necessarily indicate that the liquid is unusable. However, beware of a dramatic or unexpected color change.  

In that case, take a closer look. Check for changes in:

• The smell
• Consistency.

If anything seems off, switch to a new bottle. Don’t keep using an e-liquid that feels vastly different from the original.

The smell is different

You can detect an early sign of an e-liquid change through smell. Fresh vape juice will usually smell like a particular flavor profile.

Do not use an older bottle if it smells:

• Unusual
• Sour
• Chemical
• Unpleasant.

An unexpectedly strong odor may mean a breakdown in components or exposure to improper storage conditions.

The flavor has changed

Another way to tell if your e-liquid has gone bad is when you notice a difference in flavor. Some people may find that the flavor is unusually:

• Strong
• Dull
• Bitter
• Different than their usual.

However, don’t jump to the conclusion that the issue is the liquid. A damaged coil can also cause flavor issues. Try changing the coil and see whether the e-liquid has a normal flavor. If so, the juice is still okay.

The liquid has turned unusually thick

E-liquid comes in a certain viscosity as per its formulation. It may be time to replace it if:

• The texture has significantly altered
• The liquid is not acting as it should.

Never add water to adjust the consistency. Use the product according to the manufacturer’s guidelines.

It has been stored incorrectly

The condition of vape juice can be affected by where and how it is stored. Some conditions can speed up the liquid change. This includes:

• Repeated changes
• Exposure to excessive heat
• Direct sun, air, or temperature

Close bottles tightly during storage. If the bottle has been sitting in a hot area for a long time, examine it thoroughly.

You can’t remember how long you have had it

If you have multiple bottles on hand and don’t know when you opened one, look at the label and condition of the bottle. E-liquid is exposed to the air when opened. This can cause the characteristics to change over time.

When in doubt, it’s better to replace an old bottle. You can also review the product details and storage instructions given by your Calgary vape delivery provider.

There are signs of contamination

Do not use E-liquid if the contents, bottle, or cap seem contaminated. Warning indications include:

• Foreign particles
• Unexpected separation
• Damaged packing
• An odd appearance.

Filtering or altering dubious e-liquid is not advised. Use a fresh, well stored product.

The bottom line

You may need to replace your vape juice if its color, flavor, texture, smell, or appearance changes. Proper storage can help maintain its state. But it cannot stop e-liquid from changing over time.
