Why Is My CBD Vape Oil Turning Dark Brown or Black?

There you are, just enjoying your CBD vape oil when all of a sudden you notice something: it’s turning a dark brown or black color. While this change may give you a bit of a shock, there is no reason to be concerned about it. In fact, this change in color is actually quite normal and natural.

So before you panic and throw away your vape oils and cartridges, take a moment to understand why your CBD vape oil is turning dark brown or black in the first place!


Why CBD Vape Oil Turns Dark Brown or Black

Quality CBD vape oils do not contain additives or preservatives and are full of bioactive ingredients that will change over time. 

These changes in color do not necessarily mean that your vape oil cartridge has gone bad. All that has happened is that the natural elements in the oil have reacted to heat, light, and sometimes, age. 

Each time you use your CBD vape oil, you will be exposing it to heat and oxygen. This initiates the oxidation process, causing the oil to change colors. 

The older the CBD vape oil is, the more likely it is to have gone through oxidation. 


Tips For Maintaining CBD Vape Oil

Again, CBD vape oil turning dark brown or black does not mean that it has gone bad, but it can serve as a reminder to properly store your vape oil and to use it up within a reasonable period of time. Try to use your CBD vape oil within 6 months of purchasing. 

While it will be impossible to avoid oxidation all together, here are some things you can do to ensure the quality and integrity of your CBD vape oil. 

  • Store your CBD vape oil cartridges and pods in a cool, dry, dark place. Leaving your CBD vape oil in the sun or in a warm place (like the car) will accelerate oxidation and make the oil change color more rapidly. Storing it in a cool, dark place will help to preserve the integrity of your CBD oil for a longer period of time. 


CBD vape oil products that use hemp oil as a carrier liquid are more likely to experience oxidation. This is based on little more than the fact that hemp oil contains unsaturated fatty acids, which are more susceptible to oxidation. 


Always look for a transparent brand that posts Certificates of Analysis so you know exactly what is in your CBD vape oil. Buying a quality vape oil that contains the fewest ingredients possible will help you avoid rapid degradation that can come with repeated use and the passage of time. In other words, the better the CBD vape oil, the longer it should last — within reason of course. As mentioned before, try not to leave your CBD vape oil sitting around for longer than 6 months. The natural compounds contained within it are unlikely to hold on for too long after that, leaving you with a less potent vape oil.

If your CBD vape oil starts to turn a dark brown or black, do not panic and do not throw it away. In all likelihood, it has begun the process of oxidation and is still okay to use. While it can look concerning, it really isn’t. If you buy a quality product, store your CBD vape oil properly, and use it within 6 months, you have absolutely nothing to worry about.
