When it comes to CBD and delta 8 THC vape carts, you may have come across the terms CDT and non-CDT. CDT stands for “Cannabis-Derived Terpenes” which refers to vape cartridges that contain a group of compounds called terpenes that are naturally produced in the hemp plant. Delta 8 THC cartridges that contain only delta 8 THC distillate are known as non-CDT cartridges, while those that are combined with terpene extracts from hemp are known as CDT carts. If the terpenes aren’t derived specifically from hemp, they’re considered botanically-derived terpenes (BDT).

While it’s true that the presence of terpenes in your vape cart can significantly enhance the effects of the delta 8 extract, it doesn’t necessarily have to be from hemp for this to work. Limonene extracted from hemp is the same limonene that’s extracted from lemons, the only difference is that the hemp-derived version is five times as expensive.

The problem with CDT is that there’s no way to truly verify the origin of a particular terpene. Companies can use terpenes extracted from other plants to make their cartridges, and the third-party analysis will look identical to products made with the same terpenes derived from hemp. This is because there’s no structural difference between a given terpene derived from hemp and the same terpene derived from another plant source. Bisabolol is always bisabolol whether it’s from hemp or chamomile, and pinene is pinene whether it’s extracted from hemp or pine.

Understanding the Sourcing of Terpenes

Some terpenes, such as myrcene, are abundant in the essential oil of hemp, so it makes sense to use myrcene extracts from hemp (CDT). However, others, like ocimene or geraniol, are produced in such minuscule concentrations that it would cost a fortune to isolate and concentrate it into any usable quantity from hemp. In these cases, it makes more sense to obtain this terpene from another plant source.

Companies that claim to source all their terpenes from hemp (AKA, CDT carts) are very likely exaggerating this claim. They may use one or two hemp-derived terpenes, but the rest will be sourced from other plants. This is misleading and isn’t what a true CDT really is.

The real concern when it comes to vape carts is whether the terpenes used are naturally occurring at all. There are a lot of carts on the market today that aren’t using real terpenes. They’re using synthetic fragrance oils and other synthetic flavorings to provide the taste of the cart. These products should be avoided at all costs. Some of these compounds have been shown to mimic various hormones in the human body, which can cause chronic health conditions if used repeatedly. Luckily for you, we would NEVER sell any products without legitimate lab reports!

How to Choose the Right Product?

When it comes to assessing the quality of vape ingredients, it’s important to stick to naturally-flavored delta 8 carts and avoid anything that uses words like “fragrance oil” or “natural flavors” on the label. This is the “marketing friendly” term for synthetic terpenes.

At D8 GAS, our carts and disposable pens use a combination of hemp-derived terpenes and botanically-derived terpenes. We use hemp-derived components when it makes sense, and source terpenes from other plant sources when hemp-derived versions become cost-prohibitive. Our goal is to provide the best quality and most natural product possible, while keeping the costs affordable for our customers.


In conclusion, while CDT is a term that you may come across when shopping for vape carts, it doesn’t really hold much weight in terms of determining the quality or effectiveness of a product. It’s important to focus on other factors such as the quality of the delta 8 THC distillate and whether the terpenes used are naturally occurring or synthetic. Additionally, it’s worth noting that even if a product is labeled as CDT, it doesn’t necessarily mean that all the terpenes used are derived from hemp.

Companies may use a combination of hemp-derived and botanically-derived terpenes to keep costs down, and there’s no way to truly verify the origin of a particular terpene. To ensure you’re getting the best quality product, it’s important to do your research and read reviews from other customers, and always make sure to purchase from a reputable source.
