Common Vaping and CBD Terms

18350 Battery:

A smaller battery used in compact vaping devices

18650 Battery:

A type of battery and by far the most widely used battery in vaping today.

18500 Battery:

A medium sized battery, sits between 18650 and 18350, is also used in smaller mods.

20700,21700 Battery:

A larger battery recently developed, slightly larger and has more capacity than the 18650.

26650 Battery:

Largest type of vape battery, is rarely used but some mods and mech mods are available that fit this battery.


Stands for 50% VG / 50% PG, normally results in a thinner composition.


Stands for 70% VG / 30% PG, is one of the most popular e-liquid composition and is great for every type of atomizer.


Stands for 80% VG / 20% PG, normally results in a very thick e-liquid, and ideal for cloud chasing.

510 Compatible battery connection:

The 510 compatible battery connection is the most widely used fitting size in the vaping equipment market and has become the nearest to a universal size fitting. It refers to the thread that connects the battery to the tank. Buying a piece of kit with a 510 connector means it's likely to be compatible with kit’s from different manufacturers.


A substance added to food in small quantities to improve the taste, appearance or preserve it.

Adjustable airflow:
Most vape tanks usually have two or three air vents of varying size drilled into their sides to allow airflow. Some have mechanisms to adjust the amount of airflow, most commonly a dial or a rotating ring. Adjusting the airflow allows the vaper to control the intensity and thickness of the vapour.

APV stands for advanced personal vaporiser and they look like enlarged pens but can also refer to box mods. These are vaping kits with a detachable, rechargeable battery, sometimes with voltage and/or wattage control. They also have a separate tank that connects to the mod with a universal type pin like a 510 connector. Some APVs also have replaceable and rebuildable atomisers.

Atomiser head:
Another name for a coil. An atomiser head is a small heating element with a wick that screws into your tank and is powered by your battery. When the battery is powered up, the atomiser heats the e-liquid in the clearomiser and turns it into vapour which can then be inhaled via the tank's mouthpiece.

Batteries come in sizes ranging most commonly from 450 to 3000 mAh (milliAmp hour) and the higher the mAh number, the longer the battery will last between charges. Most batteries are user-controlled and have activation buttons which you press as you puff. More advanced models also allow control of the level of power generated by the battery, which in turn dictates the intensity of the vapour produced. Batteries are charged via a USB plug and it's absolutely essential that you follow the battery manufacturer's instructions on charging, otherwise there's a real risk of fire. You can also get external batteries which carry a lot more charge (typically 3000mAh each). These batteries fit into the more advanced mods designed for Sub-Ohm vaping that need a lot more power.


The amount of the substance that enters the bloodstream and can be used by the body.

Box Mod:

A certain style of e-cigarette device or vaping device which is shaped like a box.

Biphasic Effect:

This is a term that describes the effect when a substance acts in two different ways as the concentration increases.

Broad Spectrum:

A CBD product that has more than one cannabinoid, but not all that occur naturally within the hemp plant. For example, a product that has had the THC removed is considered Broad Spectrum.


The broad term used to cover a group of plants used to produce fibres, medicine, food supplements and by some as a recreational drug. This term includes the high THC varieties used for medicine and recreational use. It also includes low THC hemp which is used for CBD supplements and fibres for clothing, plastic and insulation.

Slang terms for cannabis include marijuana, skunk, Mary Jane, weed, pot, dope, grass and reefer. In general, these slang terms refer to the high THC varieties used for recreational consumption.

Cannabis Oil:

Cannabis oil is different to CBD oil in that it is produced from cannabis plants high in THC rather than hemp plants which are low in THC. Commonly cannabis oil is intended to be high in THC and low in CBD but can also be a balance of the two. This type of product is ilegal in the UK unlike CBD oil produced from hemp plants. 

Cannabidiol (CBD):

Cannabidiol also known as CBD is a non-intoxicating cannabidiol found in varieties of the cannabis plant as CBDa (see the next term). Cannabidiol available in the UK can only be produced from the hemp plant (Cannabis Sativa L.) which is low in the intoxicating component THC.

Cannabidiolic Acid (CBDa):

CBDa is a naturally occuring cannabinoid found in the cannabis plant that is the precursor to cannabidiol (CBD). CBD is not a naturally occurring molecule, it is produced when CBDa is heated (decarboxylation) to remove the acid molecule. CBDa and CBD have different effects when consumed, which is why you can also purchase products that are high in CBDa such as hemp tea bags.

Cannabigerol (CBG):

Cannabigerol is another one of the many cannabinoids found in the cannabis sativa L. plant. It is found in large amounts in some industrial hemp varieties as its precursor CBGa. Currently clinical research of how CBG works in the human body is at an early stage. CBG is noyt a controlled substance in the UK or elsewhere. 

Cannabinoid / Phytocannabinoid:

Cannabinoids are chemical components found in the cannabis plant. They include THC (Tetrahydrocannabinol), CBD (Cannabidiol), CBG (Cannabigerol), CBN, CBC (Cannabichromene) and THCV (Tetrahydrocannabivarin). To date there are 113 known phytocannabinoids.

Cannabinol (CBN):

Cannabinol is a cannabinoid found in the cannabis plant. Like THC it is a controlled substance in the UK and should not be found in levels of more than 1mg per container in CBD products. CBN occurs when THC ages. It is mildly psychoactive and is believed to have effects as a neuroprotectant and in reducing intraocular pressure.

Carrier Oil:

Carrier oils are those that are used to dilute essential oils ready for application. These are usually made from vegetable oils such as coconut or avocado. In the case of CBD the most common are coconut oil (MCT oil), hemp seed oil and olive oil. Often carrier oils are odourless with a slightly nutty flavour. This taste can often be detected when you take CBD under the tongue.

A cartomiser is similar to a clearomiser and has a tank for e-liquid, a coil and a mouthpiece. The term usually refers to a clearomiser that has an inbuilt coil so that once the coil burns out, the whole cartomiser must be replaced. Some cartomisers come pre-filled with e-liquid and are not refillable, while others can be refilled.


A device used to charge a battery. Always use the correct charger, such as the one provided with a rechargeable product, or an authorised replacement.

Clapton Coil:

A special type of e-cigarette coil.

A clearomiser is a refillable tank for e-liquid with a mouthpiece and an atomiser head/coil. Tank capacity is generally between 1.5 and 2ml. The maximum tank capacity you can get under TPD in the UK and Europe is 2mls.

Cloud Chasing:

To modify your vape to create as much vapour as possible, cloud chasers also compete to create the largest “clouds”.

CO2 Supercritical Extraction:

This is a method used to extract cannabinoids from the hemp plant. It is used due thehigh level of concentration it has over temperature and pressure. This method ensures that the oil produced is both pure and clean whilst protecting the active cannabinoids and terpenes found in the cannabis plant. 

Another advantage of this method is that you can separate the constituent oils and remove anything that is not wanted in the final product. For instance, THC, so a broad-spectrum oil can be produced to guarantee that it will not have too much THC and break UK law.

The coil is a short length of thin wire that is wrapped around the wick of an atomiser. It's the coil that heats up when the battery is activated and acts to vaporise the e-liquid in the tank. The coil can be of different thicknesses which vary its resistance measured in ohms. Ohm values are commonly 1.8, 2.2 and 2.4 and the lower the number, the more heat is generated.


This is a common term used amongst cannabis and CBD consumers. A concentrate describes a substance where by the diluting agent is either reduced or removed altogether to produce a higher purity product (80-99%).

A CBD oil is usually diluted with hemp seed or MCT oil, this is referred to as a carrier oil. A concentrate will not have any of these additional ingredients. Examples include CBD crystal isolate, wax, shatter, crumble or live resin. These are normally consumed as dabs (a method of vaporisation) which are inhaled for fast acting effects.

Drip tip:
A drip tip is a mouthpiece that fits on to the end of your vape tank. There are two types of drip tip on the market, one that pushes into place and another that screws into the clearomiser. Drip tips are designed to minimise leakage and to give a good airflow when vaping. You can get drip tips in varying diameters, the wide bore options are designed to enhance cloud production and the narrow ones for mouth to lung vaping to enhance flavour.

Dry Burn:

A method used to clean the coils in an atomizer by activating the device without a tank of liquid attached.

Dry Hit:

An unpleasant taste when using a vaping device, triggered by not enough e-liquid being saturated in the wicks when you activate the device.


A type of atomizer which is customisable, allowing the user to drip e-liquid onto their wicks.


Vaping with an RDA is called ‘dripping’ as you have to literally drip e-liquid on to your coils.

Direct To Lung (DTL):

Used to describe an atomizer with open air flow, meaning to vape it you have to directly inhale the vapour in to your lungs.


An E-Cigarette.


Edible refers to products containing CBD that can be eaten. This include CBD gummies, chewing gum, mints and chocolates.

eGo is a term for the second generation e-cigarettes which have a separate battery and tank. Like a 510 connector, it’s another type of threading between the tank and battery. Some eGo tanks have integral atomisers which means they are disposable and must be replaced when the coil burns out, others have replaceable coils. Most eGo equipment comes with industry-standard 510 screw fittings so that batteries and tanks can be adapted to the more modern 510 connector threading.

E-Liquid or E-Juice as it's sometimes called, is the liquid in e-cigarettes that, when heated, produces the smoke-like vapour. E-liquids come in a huge variety of flavours and tend to be sold in small bottles with a capacity of between 10 and 100 millilitres. Three main ingredients are used in the preparation of e-liquids, plus flavourings, of which there may be more than one. The main three ingredients are propylene glycol (PG), vegetable glycerin (VG) and nicotine. Any bottle of e-liquid that’s over 10mls in capacity will now be nicotine free due to TPD regulations.

Entourage Effect:

The entourage effect is a term used to describe the process whereby a combination of cannabinoids is considered to be more effective than an isolated molecule.

Flooding is the term used to describe when e-liquid leaks into places it shouldn't, especially when you puff and get a mouthful of liquid. There are two main reasons for flooding. The first is overfilling the tank which means it can't function properly. The second is when you accidentally drip e-liquid down the hollow shaft in the centre of your coil. This leads directly to the mouthpiece and means you will inhale e-liquid. Avoid flooding by only filling your tank to its capacity and by making sure liquid only goes around the central column leading to the mouthpiece.

Full Spectrum:

Full-spectrum refers to the cannabinoids and terpenes in the oil produced from the cannabis or hemp plant. A full-spectrum oil will contain all of the naturally occurring cannabinoids. This is unlike a broad-spectrum product that will only include a select few. Some people prefer a full-spectrum product because the full range of cannabinoids contributes to the aforementioned entourage effect.


A rebuildable atomizer which is a combination of a tank and a RDA.


Hemp is a strain of cannabis plant that is grown specifically for industrial uses. Unlike the variety used to grow recreational cannabis it is low in THC and has thick fibrous stems. Uses for industrial hemp include making rope, textiles, paper, bioplastics, insulation, fuel, hemp seed oil and extracting CBD.

Hemp Seed Oil:

This is the oil produced by pressing the seeds of the hemp plant. They are low in cannabinoids such as THC and CBD but high in vitamins and fatty acids. This oil is used for salads, cooking and as a carrier oil for CBD products.

High VG:

High VG refers to the ratio of vegetable glycerin in an e-liquid. Especially popular with Sub Ohm vapers due to its cloud producing ability, high VG liquids are thicker and require more power to turn into vapour.

High Resistance:

An atomizer can have a high resistance meaning that it is capable of being used with high voltage vaping devices.


A pure source of CBD (usually 99%), where during the extraction process, everything naturally found in the plant removed. This includes any trace of THC, terpenes, waxes, oils and chlorophyll. CBD isolate usually comes as a crystal or a powder.


A type of wire used to make coils in atomisers.


This can ahppen when too much e-liquid is flowing to the wicks, and the wicking material cannot absorb it all. The excess e-liquid will leak from the holes designed for the air flow.

Low Resistance:
The coil that heats up inside the atomiser to vaporise e-liquid is made of wire. This wire can vary in thickness and the thicker it is, the higher is the resistance. Resistance is measured in ohms and you can get pre-made coils from as low as 0.15ohms all the way up to 1.8ohms. Lower resistance leads to faster use of e-liquid, a hotter vape and thicker clouds of vapour.

Max VG:

An e-liquid with the maximum amount of VG possible.


Milliampere hour. The higher the rating, the longer the battery will last.

Mechanical Mod:
A mod is a vaping setup that can be modified in terms of output by the user. Mod is short for modification and some vapers customise battery packs and tanks (including the likes of RDAs and RTAs). In some cases, enthusiasts build their kits from scratch using basic components.


A thin piece of stainless steel sheeting used in genesis style tanbarks. Used instead of silica wicks.


The unit of measurement for nicotine strengths.


A unit of measurement for liquids.


An advanced electronic cigarette or vaping device. They offer more functionality and power.

Mouth to Lung (MTL):

Describes a restricted airflow, more like a cigarette, where you take the vapur into your mouth first and then down into your lungs.

Nic Salts:

Nic salts (shortened from nicotine salts) are an alternative form of nicotine that results in a faster, stronger hit. This format is more stable than freebase nicotine, making for easier absorption and less throat hit. E-liquids containing nic salts give you a higher strength without compromising on flavour.

Nicotine Shots:

A nic shot is generally a 18mg 10ml bottle of e-liquid with no flavouring. It is designed to pour into a 50ml short fill e-liquid to make a 3mg 60ml bottle of e-liquid. Designed to work around TPD regulations.


The electrical resistance measurement which is used to measure the resistance in atomisers. A resistance of 1.0ohm or less is known as Sub-Ohm Vaping.

PG is an abbreviation for propylene glycol and it's a key ingredient in most e-liquids. E-liquids commonly contain four basic ingredients, PG, VG (vegetable glycerin), nicotine and flavourings, with zero nicotine liquids having only three ingredients. PG is a manmade, slightly watery liquid with no colour, a barely perceptible smell and a slightly sweet taste. It's commonly used in medical devices and in the food industry in products like fizzy drinks, salad dressings, and ice cream. PG-high e-liquids produce thinner vapour and more throat hit than high VG liquids. They also clog up your atomiser less than high VG liquids.


(See also: cartomisers). Pods are similar to vape tanks in that they hold e-liquid but are slightly different by design. Instead of having a replaceable coil, they have one built in. Pods are typically designed for mouth to lung devices and are optimised for using with high PG liquids and nic salts. They can come pre-filled with liquid, in which case they’re single use. Or, you can get open pods which allow you to choose your own liquid and you can refill them multiple times and keep using them until the coil burns out.

Pod Mod:

A pod mod is an ultra compact all in one vape device. Normally has pre-filled disposable cartridges called pods, and are designed to have high strength nicotine. Very effective for coming off cigarettes.


Psychoactive means something that acts upon the central nervous system to alter brain function. The alteration of brain function can cause changes in mood, perception and behaviour.


Personal Vaporiser, generally refers to any box mod or unit that powers the atomiser.


RBA stands for rebuildable atomiser. This refers to both RDAs (rebuildable dripping atomisers) and RTAs (rebuildable tank atomisers). Both of these allow you to build your own coil and wick yourself with your chosen material, typically organic cotton. You can adjust the resistance to your liking and use different wire types according to your vaping preferences. They’re typically more economical than pre-made coils as they last for longer. To re-use you’ll usually only need to replace the cotton when it wears out.


Measured in Ohms and relating to the coils. The lower the resistsnce, the lower the voltage needed to heat the coil.


An unintended electrical connection. It can cause the device to fail. Many e-cigarettes or vaping devices have safety features to protect users from dangerous outcomes of short circuits.

Short fills:

Short Fills are larger bottles of nicotine free e-liquid that have spare space at the top for you to add a nic shot. TPD regulations mean you can no longer purchase e-liquids with nicotine in bottles larger than 10mls. Short fills allow you to mix to your desired nicotine strength with the aid of a 10ml bottle of concentrated nicotine.

Starter Kits:
Many equipment manufacturers sell starter kits. These can be anything from basic cigalike kits through to quite sophisticated second generation vaping set-ups. The second-generation ones will generally include a battery and sometimes a spare battery, a clearomiser and a USB charger. The clearomiser may be of the disposable kind or alternatively of the type where the atomiser heads/coils can be replaced. Some sellers also include a free sample bottle of e-liquid.


A device with a built in bottle which you can squeeze to wick the e-liquid into your atomiser.


When you vape with a Squonk Mod, it is called Squonking.


Steeping is the process in which e-liquid is left to ‘age’ to get the best flavour. Similar to wine. For some e-liquids steeping is necessary and would typically need to be steeped for 1-2 weeks at least.


A device with a built in bottle which you can squeeze to wick the e-liquid into your atomiser.


When you vape with a Squonk Mod, it is called Squonking.

Sub Ohm Vaping:

Sub-Ohming refers to vaping on a device with a resistance level of less than 1.0 Ohms. All beginner style coils operate at more than 1.0 Ohms. However, some coils are capable of going below this point, those that do are called ‘sub-ohm’.

Sub-Ohm Tank:

A tank which is capable of using low resistance coils which in turn require more battery power to be used. A step up from beginner tanks which offers more flavour and vapour.


Sublingual literally means “under the tongue”. This refers to a method of CBD consumption whereby the liquid is held under the tongue to absorb the active ingredients.

A tank is sometimes used as an alternative term for clearomiser but strictly speaking it is the part of the clearomiser where e-liquid is stored. In second generation vaping equipment kits, tanks are refillable, either via a hole at the top when the mouthpiece is removed, or via a gap in the bottom where the tank screws into the atomiser and battery.

Tetrahydrocannabinol (THC):

The most well know cannabinoid found in the cannabis plant. THC is the cannabinoid that is known for the “high” feeling associated with recreational cannabis use. Many modern cannabis varieties have been bred to have higher levels of THC than any other cannabinoid.


Terpenes are aromatic oils that give cannabis (and other plants) their particular aromas and taste. More than 120 cannabis terpenes have been identified. They exist in varying proportions in cannabis strains and are known to have different effects on humans and animals.

Throat Hit:
Throat hit is the feeling you get at the back of your throat when vaping and is like a kind of gentle rasping sensation. It is a feeling familiar to conventional cigarette smokers, especially those who smoke high-tar cigarettes. It’s often a priority for transitioning smokers who are just getting into vaping as it emulates the familiar feel of smoking a cigarette. Throat hit can be increased by vaping higher nicotine e-liquids and e-liquids with high proportions of PG.


A product or method that requires you to apply it directly to the skin. Topical products are typically creams, balms, lotions and ointments. Topical products are not designed to cross to the blood stream but to focus on the area it has been applied to.


Your e-cigarette or vaping device. Or to use your e-cigarette, as in ‘to vape’.


A user of e-cigarettes or vaping device. ‘ I am a Vaper’.

Vapers tongue/Vape mouth:

Vapers tongue is when you start to find your e-liquid flavour is getting a bit muted. This often happens when you’ve been using the same vape juice for a while but can also stem from having a dry mouth. Alleviate this by drinking lots of water, using a higher VG liquid (PG is more drying than VG) and changing your flavour now and again so your taste buds don’t get too used to it.

Variable voltage/Wattage:
Some mods have chipsets and controls that allow you to vary their output by changing the voltage or wattage produced by the battery. This allows advanced vapers to control the volume, thickness and heat of the vapour produced by their vaping kit.

VG is an abbreviation for vegetable glycerin and is one of the ingredients of e-liquid. E-liquids commonly contain four basic ingredients, PG, VG (vegetable glycerin), nicotine and flavourings, with zero nicotine liquids having only three ingredients. VG is a colourless liquid with virtually no odour, and it is thicker and sweeter than PG. It's extracted from plants and also widely used in food production, as well as in cosmetics and toiletries. VG-high e-liquids produce thicker vapour, less throat hit and are more likely to clog up your atomiser than high PG liquids.

Water Soluble:

Water soluble means that the product can be dissolved in water.

The wick is part of the atomiser and it is a piece of material that looks like wadded up material. It draws the e-liquid from the clearomiser tank so that it comes into direct contact with the atomiser coil, the wire that heats up when the battery is activated. By bringing the e-liquid into direct contact with the coil, the wick allows the liquid to be heated sufficiently to turn into vapour which can then be inhaled. Organic cotton is typically the preferred and most common form of wicking material in both pre-made and homemade coils.
