Why Might CBD Vape Oil Get a Bit Cloudy?

If you prefer to enjoy your CBD in vaping form, you’re far from alone. Vaping the compounds of the hemp plant is easily the most popular way for exploring the properties of cannabidiol. Add to that, because demand is so high, there are countless CBD vaping products on today’s market.

While vaping CBD is overall a very uncomplicated and consistently satisfying way to experience the hemp plant, occasionally, you may need to do some troubleshooting. One “issue” that is somewhat common is cloudy e-liquid, which we will be discussing today.

We often get asked, why is my cart cloudy? If you have a cloudy THC cart, you’re not alone, but that doesn’t mean that a cloudy Delta 8 cart is a good thing. Let’s take a closer look at why my carts get cloudy below!

The Ingredients in CBD Vape Oil

To understand why e-liquid can go cloudy from time-to-time, we first need to talk about what CBD vape oil is. In short, it’s any e-liquid containing hemp extract. Hemp extract refers to a concentrate produced by extracting the desirable compounds from the raw hemp plant material. It creates an oil-based extract that can act as the sole ingredient in a vape oil formula or be blended with other ingredients.

Some CBD vape oils dilute the hemp extract with an ingredient like MCT oil[1] or propylene glycol (PG)[2]. Others add flavoring ingredients or essential oils to enhance the taste of the product. This could be one of the reasons why you’re ending up with cloudy CBD oil or why your oil cartridge is cloudy.

CBD vape oil is designed to be vaped out of a CBD vape pen. With CBD vape oil bottles, you can refill a CBD vape pen cartridge multiple times. Each milliliter of vape oil provides around 700 puffs. CBD vape juice products come in isolate and full spectrum forms.

Note: Pure CBD Now carries strengths ranging from 25mg to 4000mg.

Another common question that we get asked is why is my cart foggy, or why is my cart fogging up? If you have experienced this issue, you’re not alone. 

Can You Vape Cloudy CBD E-Liquid?

Now, before talking about reasons why CBD vape oil can get cloudy, we need to first discuss whether or not it’s actually safe to vape your e-liquid when this happens. In short, there is no reason why cloudy vape juice is dangerous. You will see that cloudiness is not an indication that there is something wrong with the e-liquid in the sense that it has become harmful.

So, if your oil cartridge is cloudy or you have a cloudy cart, it’s no reason to panic or throw it away and waste it. Depending on what you’ve been doing, you can end up with a cart that contains CBD isolate, which goes cloudy or why your cart looks cloudy.

Reasons Why CBD Vape Oil May Be Cloudy

Vape oil can go cloudy for a number of reasons, and we are going to discuss the most common ones so that you can diagnose the issue and fix it accordingly.

Reason #1: Temperature

Easily, the most common reason for cloudy e-liquid is that it has been exposed to cold. When e-liquid gets cold, it separates, as each component of the vape oil responds to temperature differently. This separation causes some components to thicken, and the ones that have thickened will intermix with the liquid and cause cloudiness. If your CBD e-juice has been exposed to cold, simply give it time at room temperature to return to its normal state.

#2: Coil

The coil that is inside the cartridge or tank, whether you are using a pre-filled cartridge or bottled CBD vape oil that can be poured into the tank, can cause cloudiness if the cart or tank is past its prime. This is because its inability to properly heat the e-liquid can lead to an inconsistency of the product itself. So this could be one of the reasons why you’re asking yourself what does it mean if your cart is cloudy or why you have a cloudy vape.

#3: The CBD Vape Oil’s Quality

Sadly, not all CBD vape oils are created equally. Low-quality vape oils may be prone to cloudiness due to poor quality. Either the vape oil contains cheap ingredients that cannot handle the demands of the cartridge or tank and therefore change in their consistency when heat is applied. Or, perhaps, the ingredients are chemically unstable, and therefore separation occurs within the tank or cartridge. 

Another possible problem is that the ingredients were not blended together well, to begin with, and so they are naturally prone to separation throughout your CBD vaping experience.

#4: A CBD Vape Oil’s Age

Age is yet another factor that can cause cloudiness or a cloudy vape pen. As vape oil ages, its ingredients naturally separate from one another due to changes on the molecular level. This separation will cause cloudiness to occur as the formula in the cloudy vape cart can no longer remain homogenized. Again, aged vape juice is not dangerous, but it will likely be an issue as separated vape juice can potentially clog your tank or coil or simply give you inconsistency issues with each hit.

You should always aim to buy fresh e-liquid rather than vape juice that’s cloudy from a trusted company/manufacturer, as reputable ones are less likely to sell you vape oil or a cloudy cartridge that has been sitting on the shelf for a long time.

Quick Thoughts

The appearance of cloudy vape oil in your cartridge or tank may be concerning and even may deliver an unsatisfying vape experience. A cloudy oil cartridge isn’t the end of the world, luckily. It’s not harmful, but it can still be a disappointment depending on the culprit behind the issue. Fortunately, in many cases, it is easily remedied and does not require that you throw out your CBD vape oil.

Some of the most commonly asked questions we encounter are why is my vape juice cloudy, why does my cart get foggy, and why is my THC cartridge cloudy? However, regardless of how you ask, a cloudy vape cart isn’t an uncommon occurrence when it comes to cannabinoid vapes such as CBD or Delta 8 THC.
