CBD Vaping – What’s the Difference Between CBD E-Liquid and CBD Oil?
By Emily Ledger
Cannabidiol – known more generally by its abbreviation, CBD – is becoming commonplace in the UK market. A growing collection of products now incorporate the product. In fact, the cannabinoid can now be found in chocolates and drinks and even in clothing and pillows, to name a few!
Yet, CBD oils and e-liquids remain among the most popular products on the market. Although they might look much the same, it is important not to mix them up CBD oils and e-liquids. So, what is the difference between them?
The non-psychoactive cannabis derivative has been found to have a number of potential benefits, from relieving feelings of stress and anxiety to improving sleep and even reducing pain. Vaping and the use of sublingual (under the tongue) drops are two of the most popular ways of taking CBD.
The popularity of these products is probably owed to the high bioavailability that they offer. Bioavailability refers to the percentage of the compound that is effectively absorbed by the body. Vaping and sublingual application happen to have some of the highest rated of absorption for CBD consumption.
What is a CBD E-Liquid?
Vaping has become increasingly common around the world, as many people look for a less unhealthy alternative to smoking. In many cases, vape products may contain nicotine to ease the transfer from smoking to vaping. However, a growing number of people are now looking to vape products for other uses – namely, as a way to safely and conveniently incorporate CBD into their everyday lives.
CBD e-liquids, also known as CBD vape juices, are applied to vape pens which convert the liquid into vapour. This vapour is then inhaled by the consumer. Other products available on the market include ready-filled CBD pens. Vaping is believed to be the most effective way to administer CBD, thanks to high absorption in the lungs.
What are CBD Oils?
CBD oils or tinctures are becoming increasingly common and can be easily sourced from many stores, both online and on the high street. These oils can be used in a number of ways, including being dropped and held under the tongue, and applied topically (directly to the skin).
These products are often sold with a dropper and are known as ‘tinctures’. They allow for easy application, both sublingually (under the tongue) and topically. Second to vaping, CBD is believed to have amongst the highest bioavailability when applied sublingually. This is due to thin barriers between skin surface and veins under our tongues.
Although these products are perfectly safe for oral and topical consumption, they shouldn’t be confused with e-liquids/vape juices and inhaled as a vapour.
What is the Difference Between E-Liquids and Oils?
CBD e-liquids and oil products often look very similar, with both commonly sold in small glass bottles. However, each product is designed specifically for its intended use and should not be mixed up.
CBD oil products are usually made by combining a CBD extract with a food-grade oil – commonly olive, hemp, or coconut oil. Some oils may also contain flavourings to make the oil taste more pleasant for oral consumption. These products were not designed to be exposed to high heats for vaporisation, unlike CBD vape juices / e-liquids. Using CBD oils that were not designed to be vaped may result in an unpleasant and potentially harmful vapor as well as possibly damaging the coil of your vape pen.
E-liquids are made using a CBD extract alongside a thinning agent such as PG/VG or MCT. These ingredients ensure that the liquid is thin enough to be vaporised effectively, producing a clean and comfortable vapor for inhalation. It is important to note that it is possible that CBD oils that were not designed for vaping may also contain MCT for thinning. However, this does not mean that it is safe for the purpose of vaping. To make a safe and effective e-liquid, these agents must be present in the correct proportions.
Always Check the Label
To ensure you are using your CBD products as they were, make sure to always check the labels. If the product is referred to as a ‘tincture’, then it probably isn’t intended to be put into a vape pen. The ‘How to Use’ directions on the packaging will also give you a guide to how the product is supposed to be applied. Above all, always buy your CBD products from trustworthy and responsible brands!
To avoid confusion, it may also be a good idea to simply buy a ready-filled CBD vape pen. This will take all the guesswork out of vaping the cannabinoid. There are a number of brands on the market that produce CBD pens, such as Hiatus. As well as being guaranteed the right product, this also makes dosing much more straightforward!
Although CBD oils and e-liquids might look much the same, it is important not to mix them up when vaping. So, what is the difference between them?
CBD oil under the tongue
by Tim W. Shaw October 08, 2019
Since CBD found its way into high street shops and online stores, the choices have improved. You can choose from products such as drops, sprays, capsules and gummies. You can also choose how to take it. CBD can be swallowed, placed under the tongue, vaped, rubbed into your skin or applied rectally.
Whether it’s CBD drops or CBD paste, placing it under the tongue is also known as “the sublingual method” and it is the most common way to take CBD. Despite its popularity, it is also the method that can cause the most confusion or raise questions.
Placing substances under your tongue understandably sounds a bit odd because it’s not something we often do. So, what is it about this method that makes it so widely used?
How do I best take CBD under the tongue?
The beauty of taking CBD in this way is that once you’ve tried it, it couldn’t be easier.
Simply, open your mouth and lift your tongue. Place the suggested number of drops under your tongue using the dropper that comes with the oil. Then allow the oil to sit under your tongue for between 90 seconds and 2 minutes.
It is up to you whether you keep your mouth open and your tongue raised or close your mouth. The important part is that the oil must remain in contact with the membrane under your tongue for the full time.
Do I swallow it?
Once the time has passed you can swallow any residue that is left in your mouth. This prevents any cannabidiol from being wasted. Because some CBD oils can leave a strong taste, many people choose to complete the 90 seconds and then take a large swig of water to wash down any remaining oil.
Benefits of taking CBD sublingually
The word ‘sublingual’ refers to the large blood vessel found under your tongue. When liquids are placed there, they can cross the thin membrane and enter your bloodstream. The speed with which this happens has played a key part in this method’s popularity.
Many CBD consumers report that once they are used to it, taking it under the tongue is quick and easy. It requires very little effort and can be completed in a couple of minutes without having to use any special equipment. Drops can be placed under your tongue, discreetly whether you are at home or at work.
As an extra bonus, taking CBD under your tongue means that a greater amount of it will be used by your body. This results in a greater effect from less oil, meaning that you could save money when compared to CBD products that are only eaten or swallowed.
While all there are many compelling reasons to take CBD oil under your tongue, it can still take some getting used to. The first few times you try can be tricky, it’s not always easy to tell exactly how many drops you’ve used or if your dropper is positioned correctly.
If you do find this a problem, there are ways around it:
1. Stand next to a mirror or ask a friend to help you position the dropper correctly and count out the drops. Once you’ve tried it a couple of times it gets easier and becomes quick and convenient.
2. Alternatively, there are brands who have packaged their oils specifically to make them easier to use. CBD sprays are a great way to apply the oil directly under your tongue with no fuss. Others have specially designed droppers or have marked them in ways that make it easier to apply specific amounts without any guesswork.
Why does CBD oil burn under my tongue?
When CBD is in your mouth you may notice an intense, bitter flavour. Because many high-quality oils get the best effects from using more of the hemp plant, they can be intensely grassy and bitter. While unpleasant, this alone won’t do you any harm. A mouthful of water will help with any strong flavours.
However, if you get any reaction that is worse, stop using it immediately and consult a doctor. This may only happen in two situations:
- If you have chosen poor quality oil. Unfortunately, some oils that make it into the hands of customers have not passed the same quality checks that we apply to all our products. Contamination by chemicals or other products could result in an unsafe oil.
- If you are allergic to any product contained within the oil. This is very unlikely as great care is taken to choose natural ingredients with low risk of reaction, however, it is always worth carefully checking the labels of any products before their use.
How does it compare with other methods of taking CBD?
From the 5 methods that exist on how to take CBD, placing the oil under the tongue is one of the most effective. It isn’t as effective as vaping, but because it is so simple it is still more popular.
The effectiveness of each method can be measured by the length of time it takes for you to feel an effect, and how much of the active ingredient reaches your bloodstream. The distance of this journey and the obstacles faced directly affect how effective each method is. Once CBD reaches your bloodstream it is unlikely to be broken down further and it will be transported to your body tissues.
CBD under your tongue
When you put oil under your tongue it is absorbed directly into the blood vessels. Because the vessels there are very close to the surface it allows the CBD’s journey to the bloodstream to be quick and uneventful. Substances taken this way are absorbed quickly, take effect in about 15-25 minutes and because they don’t have to pass through the liver you can expect as much as 35% to reach your bloodstream.
Eating CBD is the least effective way to take it
If you swallow CBD it travels through your digestive system and your body automatically starts to break it down. This process can be slowed down by mixing the active ingredients with other substances such as fat, but the difference is relatively small.
Most food and drink must take a ‘first pass’ through the liver, this removes toxins and breaks food into its component parts. Only about 4% of the original amount of CBD will make it through this and reach the bloodstream to be transported to cells for use. Because of the time it takes for your digestive system to process food, it can take between 30 minutes and 2 hours for that small amount of CBD to get to work.
CBD applied topically doesn’t travel in your bloodstream
Rubbing a balm or cream into your skin, unlike the other methods, doesn’t give you a whole-body effect. This is because it only goes to the cells, tissues and small blood vessels close to where you’ve applied it. It can have a localised effect within 25 – 45 minutes and up to 45% can reach the target area.
Vaping CBD is the most consistently efficient method?
Vaping is when specially prepared CBD oils are heated in a vaporiser until they form an inhalable vapor. The CBD can cross the thin, moist membranes in your lungs into your bloodstream. This means that the effects can often be felt within 10 – 20 minutes and up to 56% of the CBD can reach your blood for use in your body.
Taking CBD rectally can give inconsistent results
Inserting CBD rectally is often regarded as a quick and effective way of taking it. However, the speed of its effect and how much reaches your blood, depends on which of the rectal blood vessels absorb it and how the CBD is prepared. The effect of this method can also be reduced by health issues such as constipation and haemorrhoids.
It is currently seen to be a better method than eating CBD, but until CBD has been specifically prepared for rectal use it is not as consistently effective as taking it sublingually or with a vape.
The most effective method of taking CBD
While vaping CBD e-liquid is the most effective method, it comes with extra steps. You need to buy a vape, keep it topped up and use it only where their use is allowed.
Dropping CBD under your tongue may not be the most effective method but it is a close second. It also has an advantage in how quick and easy it is.
Another advantage of taking CBD oil orally is that it stays in your system for up to 8 hours. When you vape, the effect is faster but CBD stays in your system for only up to 2 hours.
Uptake into your bloodstream
Time to take effect
30 minutes – 2 hours
Under your tongue (sublingually)
Inhaled or vaporised

Why should I go under the tongue?
CBD is commonly taken under the tongue because it is effective, convenient and can save you money. If you are just starting to use CBD oil it is an ideal consumption method. With a little bit of practice, you will soon be able to deliver a precise amount wherever you are.
