Vaping has become a popular alternative to smoking. It offers a cleaner, healthier and more convenient way to inhale the active compounds in tobacco or marijuana. In recent years, the use of vape cartridges has skyrocketed as they offer a discreet and easy way to smoke. However, running out of a vape cartridge can be an inconvenience, and very few people know how to identify if their cartridge is empty or not.

In this article, we will discuss how you can tell if your vape cartridge is empty and some things to consider before disposing of it.

How do Vape Cartridges Work?

Before we delve into how to tell if your vape cartridge is empty, let us first understand how they work. Vape cartridges are small, disposable tanks that are pre-filled with e-liquid or oil. Depending on the type of cartridge and your vaping habits, they can last for days or weeks.

The cartridge is attached to a battery-powered device called a vape pen or a mod. When the user takes a drag, the vape pen heats the cartridge, creating vapor that is inhaled. As the user inhales, the oil or e-liquid is consumed, and the cartridge will eventually run out.

How to Tell if Your Vape Cartridge is Empty

1. Examine the Cartridge

The first step is to examine the cartridge carefully. Most vape cartridges are made of glass, while others are made of plastic. Look at the cartridge from the bottom. If you see a small air bubble at the bottom, the cartridge is not empty.

However, if there is no bubble or if you notice that the e-liquid level is below the top of the wick, then it’s time to throw it out.

2. Test the Flavor

Vape cartridges come in different flavors, and as the oil or e-liquid is consumed, the flavor will become less intense or close to nonexistent. If you notice that the flavor has decreased, it may be time to change the cartridge. A good way to test the flavor is to take small drags and pay careful attention to the taste.

3. Test the Vapor Production

Another way to tell if your cartridge is empty is to test the vapor production. When you take a drag, if you notice that there is little to no vapor, it is a sign that the cartridge is empty. However, if you are still getting a good amount of vapor when you take a drag, the cartridge is probably not empty.

Other things to Consider

1. Store Your Cartridges Correctly

To extend the life of your vape cartridges, you need to store them correctly. Store them in a cool, dry place, and away from direct sunlight to prevent them from degrading. Cartridges can also leak if stored incorrectly, so make sure they are kept upright to prevent leakage.

2. Don’t Overuse Cartridges

Overusing your vape cartridge can lead to a burnt taste or less flavor. Therefore, it’s essential to pace yourself when using them. If you start to get a burnt taste or less flavor, it could be time to change the cartridge.

3. Dispose of Used Cartridges Safely

Finally, when your cartridge is empty, it’s essential to dispose of it safely. Most vape cartridges can be recycled, so make sure to check with your local recycling center before tossing them in the trash.


Knowing when your vape cartridge is empty is essential for a better vaping experience. There are several ways to tell if your cartridge is empty, such as checking the e-liquid level, testing the flavor and vapor production. Vape cartridges are a fantastic option for a simpler and healthier smoking alternative, but knowing when to replace them is just as important. Always store your cartridges correctly, don’t overuse them, and dispose of them properly.
