If you have been searching for a THC vape, cannabis vape or weed pen, you may have come across CBD vape cartridges with familiar names such as Granddaddy Purple, White Widow or Super Lemon Haze. They can look similar to other cannabis cartridges, use similar hardware and feature recognisable flavour profiles.
That does not make them the same product.
The distinction starts with the contents. CBD and THC are different cannabinoids, and a CBD vape cartridge is not a THC vape under another name. Equally, a cannabis-inspired flavour does not tell you which cannabinoids a cartridge contains.
For adults already considering CBD vaping, understanding that difference makes shopping much simpler. You can separate the flavour you enjoy from the cannabinoid formulation, choose suitable hardware and avoid buying something based on a name alone.
This guide explains how THC vapes and CBD vape cartridges differ, what cannabis-derived terpenes actually mean, and how to choose a CBD cartridge if that is the product you are looking for.
THC stands for tetrahydrocannabinol. CBD stands for cannabidiol. Both are cannabinoids associated with the cannabis plant, but they are not interchangeable ingredients.
THC is responsible for the characteristic cannabis high. CBD does not produce that same intoxicating effect. The NHS explanation of medical cannabis distinguishes THC from CBD and explains why the contents of a cannabis product matter.
A CBD cartridge should therefore be chosen for its stated CBD formulation, rather than with the expectation that it will reproduce a THC experience. Increasing the CBD concentration does not turn it into THC.
There are also differences within the CBD category. Some formulations contain CBD alongside CBG and other cannabinoids, while others use a different cannabinoid balance. Read the individual description rather than assuming every cartridge labelled CBD has identical contents.
| What you are comparing | What it tells you | What it does not tell you |
|---|---|---|
| CBD or THC | Which cannabinoid the product is described around | The full ingredient breakdown or suitability for a particular person |
| A cannabis strain name | The named profile associated with the product | Proof that it contains THC or will produce a particular effect |
| A percentage or milligram figure | The quantity or concentration specified on the label | Whether that figure refers to CBD alone or several cannabinoids combined |
| A 510 connection | The cartridge’s connection format | Its ingredients or compatibility with every device setting |
| A CDT description | The use of cannabis-derived terpenes | That the cartridge is a THC vape |
Search terms such as cannabis vape, weed vape and cannabis pen are broad. One person might use them when looking for a dry-herb vaporiser. Another might mean a prefilled cartridge. Someone else may simply want to understand the difference between CBD and THC.
Even the word pen usually describes a device’s shape rather than what it contains.
This is why the search phrase alone is a poor buying guide. Before comparing products, identify what you actually want to understand or purchase:
If your interest is a CBD formulation with a cannabis-inspired flavour, that is a more specific requirement than simply searching for a THC vape UK listing. It also gives you a clearer basis for comparing products.
Our checklist of things to consider before buying a CBD vape in the UK takes that process further, covering the practical decisions to make before placing an order.
Names such as White Widow and Granddaddy Purple are familiar within cannabis culture. On a CBD cartridge, they can identify the flavour or terpene profile associated with the formulation.
They should not be treated as a shortcut to understanding the ingredients.
For example, a product described as a Granddaddy Purple CBD vape cartridge should be assessed using its CBD product description. The name alone does not establish a THC content, guarantee a particular feeling or tell you how it compares with another manufacturer’s product using the same name.
The same applies to terms such as indica, sativa and hybrid. When used to describe a terpene profile, they are not a dependable promise of how a finished CBD product will affect you.
A better approach is to look for three separate pieces of information: the cannabinoid formulation, the flavour description and the device requirements. Each answers a different buying question.
Yes. A CBD vape can have a cannabis-inspired flavour without being a THC vape.
Terpenes are aromatic compounds found in plants. In vape formulations, terpene blends contribute to the flavour and aroma profile. Depending on the blend, descriptions may include citrus, pine, earthiness, floral notes or a more herbal character.
The important distinction is between flavour and cannabinoid content. A recognisable cannabis aroma does not establish THC potency, just as a fruity flavour does not establish CBD strength.
You can therefore prefer a cannabis-style flavour while choosing a product formulated around CBD. Those preferences are compatible, but they remain separate decisions.
Botanically derived terpene blends use terpenes sourced from plants other than cannabis. These can be blended to create a particular aromatic profile, including profiles inspired by familiar cannabis varieties.
The source of the terpenes does not, on its own, tell you the CBD concentration or how suitable the finished cartridge will be for your preferences.
Cannabis-derived terpenes, often shortened to CDTs, are sourced from cannabis. In a CBD cartridge, they describe the origin of the aromatic ingredients rather than turning the product into a THC cartridge.
Canavape’s Reserve CDT cartridges combine cannabis-derived terpene profiles with CBD-rich formulations. They are a separate choice within the CBD cartridge range, rather than a different name for THC vapes.
For a closer look at that distinction, read our existing comparison of CDT cartridges and botanical terpene profiles.
A familiar name can be a useful starting point, but the actual flavour description is more useful when deciding what to buy.
Start with the characteristics you enjoy. Do you prefer bright citrus flavours, a more earthy profile, or something with a softer, sweeter finish? Are you interested in a recognisable cannabis aroma, or would you rather choose a fruit-led CBD vape?
Two products with different names may share characteristics you like. Conversely, two products with the same strain name may not taste identical, because the formulations and terpene blends can differ.
Try to describe your preference in ordinary flavour terms before narrowing the selection. “Citrus and herbal” gives you more direction than choosing a product solely because you recognise its name.
If you are comparing several styles, our guide to choosing between fruity, classic and cannabis terpene CBD vape flavours helps separate those options without making the decision unnecessarily technical.
The word strong can cause confusion when someone moves between THC vape searches and CBD product listings.
A strong CBD vape refers to its stated CBD or cannabinoid formulation. It does not mean that it should be expected to create a THC-like high.
It is also important to establish what the strength figure includes. A label may state the amount of CBD alone, or it may describe a combined cannabinoid total that includes CBD and CBG. Those figures should not automatically be treated as equivalent.
For example, a cartridge described as containing 400mg of combined cannabinoids is not necessarily a cartridge containing 400mg of CBD. The breakdown matters.
Use these questions when comparing CBD vape strengths:
There is no straightforward conversion that makes a particular CBD percentage equivalent to a THC percentage. They describe different substances, so shopping by a matching number can lead to the wrong expectations.
Our guide to choosing CBD vape strength offers additional background on reading product strengths. Follow the instructions for the particular product rather than choosing the highest number by default.
These terms are often used together, but they describe different parts of a vaping setup. Understanding them helps avoid ordering a cartridge when you expected a complete device.
A cartridge is the component containing the vape formulation and heating element. A prefilled CBD cartridge arrives with its contents already inside, but it usually requires a separate compatible battery.
Our historical guide to CBD vape cartridges in the UK introduces the format and the terminology you will encounter when browsing.
A CBD vape pen generally refers to the device used to vape a CBD formulation. Depending on the listing, that might mean a battery on its own or a complete combination of battery and cartridge.
Check the included items rather than relying on the word pen. A photograph showing a complete setup does not replace the product’s contents list.
Bottled CBD e-liquid is intended for a suitable refillable device. It is a different buying format from a prefilled cartridge, with its own compatibility requirements.
Do not assume a prefilled cartridge is designed to be opened and topped up with bottled liquid. Choose the format you want first, then select the hardware intended for it.
If you are still deciding what equipment you need, our recent article on buying your first CBD vape cartridge explains how the separate components fit together.
Many cartridge products use a 510 connection. This describes the threaded connection between the cartridge and battery, rather than the contents of the cartridge.
Canavape’s CBD cartridge range uses 510-compatible hardware. However, the connection is only one part of checking compatibility. The battery must also be suitable for the cartridge’s operating requirements, and any recessed cartridge space must accommodate its dimensions.
If you already have a battery, check the following before ordering:
A matching thread is not a reason to use an arbitrary power setting. Follow the instructions supplied with both components.
If you need a compatible device, browse our 510 battery range. Compare the controls, dimensions and charging requirements rather than choosing by appearance alone.
The answer depends largely on what you already own.
If you have a working battery that is suitable for the cartridge you want, a replacement cartridge may be all you need. Buying another battery with every cartridge would add equipment without necessarily improving your setup.
If you do not have a suitable device, a complete kit can make the initial purchase more straightforward. Check which battery is included, how many cartridges are supplied and whether any charging accessories are listed separately.
This is also where comparing headline prices can become misleading. A cartridge-only listing and a complete kit are different purchases, even if both appear in a search for CBD vape pens.
Our guide to choosing a replacement CBD cartridge or a complete kit walks through that decision in more detail.
Two cartridges can share a similar shape while containing different formulations. The outer appearance tells you relatively little about the cannabinoid breakdown, terpene source or quantity supplied.
Before deciding that one is better value, compare the product descriptions side by side.
Check the fill quantity, stated cannabinoid content, terpene description and whether the purchase includes any hardware beyond the cartridge itself. Where one listing gives a combined cannabinoid figure and another gives CBD alone, recognise that you are comparing different measurements.
Personal preference also matters. Paying more for a particular flavour profile may make sense to someone who specifically wants it, but a higher price does not automatically establish a better match for every customer.

Someone researching the difference between CBD and THC may be comparing products, exploring a change in routine or simply trying to understand unfamiliar terminology.
Keep the expectation clear: a CBD cartridge should not be presented as a guaranteed replacement for the effects of THC, a treatment for withdrawal or an alternative to prescribed medication.
We have a separate article discussing the transition from THC to CBD. If your reason for changing involves dependence, withdrawal symptoms or a medical condition, seek advice from an appropriate healthcare professional. Product selection alone cannot answer those questions.
For a straightforward shopping decision, concentrate on whether you want a CBD formulation, which flavour you prefer and what compatible equipment you need. You do not need to make assumptions about medical benefits to compare those features.
No. CBD and THC are different cannabinoids. A similar cartridge shape, familiar strain name or cannabis aroma does not make two formulations equivalent. Check the stated contents of the product.
A higher CBD concentration does not turn CBD into THC. Do not choose a strength on the assumption that increasing it will recreate a THC high. Compare the formulation on its own terms and follow the product instructions.
The name alone does not establish the cannabinoid content. On a CBD product, it may describe the associated flavour or terpene profile. The individual formulation information is what you need to read.
No. CDT means cannabis-derived terpenes. It describes the origin of the aromatic ingredients. A CBD cartridge can contain cannabis-derived terpenes while remaining a product formulated around CBD.
CBD and nicotine are separate ingredients. Canavape’s CBD vape cartridge range is nicotine-free, but you should check the stated ingredients of any product you are considering rather than making assumptions from its name.
Possibly, provided the connection, physical fit and operating requirements are compatible. Check the instructions for both products. A device looking similar to another 510 battery does not confirm that every cartridge or setting will be suitable.
No. A prefilled cartridge contains a formulated vape product, whereas a dry-herb vaporiser is designed for plant material. A flavour description does not make those formats interchangeable.
The most useful distinction when comparing a THC vape with a CBD vape cartridge is between what is inside, how it tastes and how the device works.
Choose the cannabinoid formulation first. Then compare flavour profiles, cartridge size and compatible hardware. Treat familiar strain names as a starting point for reading the description, rather than a promise about contents or effects.
If CBD is the formulation you are looking for, explore our CBD vape cartridges and use the individual descriptions to narrow your choice. A clear match between the formulation, flavour and device is more useful than simply buying the product with the most familiar name.
