What is CBD e-liquid? – Definition, advantages and best method of using.

CBD liquids This non-psychoactive cannabinoid is currently overtaking THC as the active principle in cannabis that medical professionals and patients alike are most interested in. So what are CBD e-liquids?

CBD e-liquids are joining CBD food supplements as the latest stage of the on-going quest to find more effective and healthier ways of consuming cannabidiol.

So what is the definition of CBD e-liquid?

This non-psychoactive cannabinoid is currently overtaking THC as the active principle in cannabis that medical professionals and patients alike are most interested in.

‘E-liquids’ is the collective term for a wide range of slightly different fluids also known as ‘CBD vape oil’ or ‘CBD vape juice’ used in a vaporizer or inhaled using e-cigarettes, or e-cigs, which are designed to be an alternative to smoking. Many e-cigarettes resemble traditional cigarettes, some are similar to large pens, and it is even possible to obtain e-pipes, for people desiring a Sherlock Holmes look.

Advantages of CBD e-liquids

The advantages of vaping CBD e-liquids are manifold. Although the full range of its medicinal properties are still at the testing stage, there is an ever-increasing amount of scientific and anecdotal evidence that the anti-emetic, anti-convulsant, anti-inflammatory and anxiolytic effects of CBD are safe, effective and highly beneficial in treating a wide range of afflictions in humans.

Since CBD is not psychoactive, all these effects are obtainable without the side-effect of getting high, which for some patients is the factor that deters them from trying any type of cannabis extract. And since e-liquids are vaporized, this removes the other common deterrent: having to smoke cannabis to achieve the effects of CBD.

A brief history of e-cigarettes

Vaping”, defined as “breathing in the vapour produced by an electronic cigarette”, was the Oxford English Dictionary’s Word of the Year for 2015, but e-cigarettes have been around for a lot longer than that, at least on paper.

In 1965, an American named Herbert A. Gilbert received a patent on his “Smokeless Non-Tobacco Cigarette” from the U.S. Patent Office. Sadly for him, not many people were interested in it; maybe it would have taken off if he’d had the opportunity to incorporate CBD in his e-liquids. By the time present-day interest in vaping occurred, his patent had long since expired.

Credit for the invention of the modern e-cigarette in 2003 goes to Hon Lik. A Chinese chemist who also studied traditional Chinese medicine, Hon Lik was looking for easier ways of ingesting remedies such as ginseng and deer antler when he hit upon vaporizing. In a way, using an e-cigarette to vape CBD liquid is closer to the original intention of the device than using it to vape nicotine.

What else is in CBD e-liquids?

E-liquids most commonly have a base of propylene glycol (PG) and vegetable glycerol (VG), to which a variety of other ingredients are added, depending on the desired effects. These ingredients include flavourings, nicotine, and – of most interest to us – the cannabinoid CBD.

Propylene glycol has a wide range of applications, from being the humectant food additive E1520 to a carrier ingredient in injectable, topical and oral drugs. A very small amount of people are allergic to it, reacting with sore, dry skin on the face and/or a rash of small red dots on the body, so watch out for this if you are vaping for the very first time. However, most allergy sufferers are already aware of their condition, since PG is used in so many everyday items, including aerosol cream, ice-cream, soft drinks, and cosmetics.

VG is also used as a humectant, solvent, and sweetener, and has been used for many years as an alternative to alcohol in tinctures and herbal extracts to preserve their quality. Both PG and VG are clear, odourless, slightly sweet tasting semi-viscous liquids which, when heated, produce a vapour that can be inhaled as a carrier for the other ingredients.

Flavourings are included simply to create a pleasant inhalation experience, referred to in e-liquid circles as ‘throat hit’ and ‘mouth feel’. Flavours range from basic (fruity, smoky, mint) to exotic (tequila, ylang-ylang, orange blossom) to downright confusing (Greek yoghurt, peanut butter, Christmas pudding).

Obviously, if you are not already a tobacco user, it’s not a good idea to start inhaling e-liquids containing nicotine since you will swiftly develop one of the most pointless addictions of the modern age.

On the other hand, if you are a tobacco user, switching to e-cigarettes with an e-liquid containing nicotine has the advantage of eliminating the tar and chemicals that are inhaled along with the smoke, and may make make it easier to quit using nicotine altogether.

The best method of ingesting CBD

Saving the most interesting additive for last, we come to CBD. Somewhat overshadowed by its psychoactive cousin THC for many years, CBD has become a serious research topic relatively recently. The first scientific paper on vaporizing it (‘A protocol for the delivery of cannabidiol (CBD) and combined CBD and delta 9-tetrahydrocannabinol (THC) by vaporisation’) was written by researchers at Australia’s University of Wollongong and published in October 2014.

This paper includes the information that “Orally administered cannabinoids result in slow and erratic absorption with limited and highly variable bioavailability. Smoking and intravenous administration […] respectively carry toxic risks and loss of active drug by combustion, or are invasive.

Intrapulmonary administration of cannabinoids is regarded as an effective mode of delivery since it results in fast onset of action and high systemic bioavailability. The vaporisation of cannabinoids […] is a safe method of intrapulmonary administration because it avoids risks associated with smoking and the formation of pyrolytic toxic compounds as a result of combustion.”

In layperson’s terms, eating CBD is hit-and-miss; injecting it is dangerous; smoking it is dangerous and inefficient; vaping it is the best option, and the one that looks set to become the next wave of medicinal consumption for this exciting and beneficial cannabinoid.

What are the best CBD e liquids? What companies are recommended?


Scarlet Palmer

Hi Kenny, thank you for your comment :)

You will be pleased to know that Sensi Seeds now has our own CBD e-liquid, just click the link for the order page. We're having really good feedback on it, do let us know how you find it in the Product Review section! Happy vaping,

Best wishes,



Graham Daniels

Hello I'm very interested in e cbd liquid but I am concerned about additives. I read that sensi grow there hemp without pesticides and herbicides which is perfect. But can you give me a list of ingredients in the vape juice? Are they anything iffy or dangerous? I'm not a fan of regular vape pens but I like the idea of cannabis compounds since cannabis is safe to use especially when vaping. Any info is much appreciated. Thank you.


Scarlet Palmer

Hello Graham, thanks for your comment and your interest in the CBD e-liquid. I have contacted the production team to request a breakdown of exactly what is in it apart from CBD, and I hope to have an answer for you shortly :)

With best wishes,



Scarlet Palmer

Hi Graham,

I checked with our producers and received the following information: "Only propylene glycol (PG) and vegetable glycerol (VG). Depending on which type of CBD e-liquid, in different ratios, but that ratio is mentioned as pg:vg on the packaging."

With best wishes,



Mr M

I cant find any information how much CBD is actually in the bottle. Packaging say: 10 ml 50 mg 99%CBD. How much of the 10 ml is 99% CBD oil and how much is glycerin and glycol?


Scarlet Palmer

Hello Mr M,

Thank you for your comment. Each 10ml bottle contains 50mg of CBD (99% pure extract), which works out at approximately 0.5% CBD content per bottle. The calculation is as follows:
50mg/10ml works out to 5mg/1ml. There is more or less 1000mg in 1ml, 5mg/1000mg=0.005, 0.005x100=0.5%. I hope this answers your question :)

With best wishes,




I never ever read such type of info before this was really incredible.



Hello Sensi Seeds,

I have recently bought the 10ml 50mg 99% CBD bottle, I'm hoping to use it to get off tobacco. I'm curious to how much should I use in the vape pen. Should I put the whole bottle in with a bit of nicotine or what?




Scarlet Palmer

Hi Colm,

Thank you for your comment. It's a little tricky to answer your question, without knowing exactly what sort of vape pen you have... I would guess that if you're trying to get off tobacco, you could use the CBD e-liquid in three batches, decreasing the amount of nicotine that you add to each one? We've had very good feedback about the efficacy of this product, so hopefully it will work for you to quit tobacco! Good luck :)

With best wishes,

The benefits of CBD e-fluids are complex. Although the full range of its medicinal properties are still at the testing stage, there is an ever-increasing amount of scientific and anecdotal evidence that the anti-emetic, anti-coagulant, anti-inflammatory and anxiolytic effects of CBD are safe, effective and highly beneficial in treating a wide range of afflictions in humans. Thanks for your useful information about CBD oil. I'm very interested in e cbd liquid but I am concerned about additives. but I want to know that how can I get it?


D Oswald Heist

Vaping the stuff tonight. Interesting flavor. Kind of reminds me of bitter lawn cuttings, not in a bad way. Sending some to Kellyanne Conway next week, on the off chance she'll try it n chill.


Walter Dorsey

Informative. I am also using these e juices as they helped me a lot to quit smoking.


william carlosseo

This is a very informative blog. Thanks for posting.



Thank you for including links to studies. As a health professional, CBD proponent and consumer, reading the studies is helpful. And yeah, I am a geek, I like reading primary material =}



Hello Sensi Seeds!

I was wondering whether your CBD e-liquid has CBD isolate or is it full spectrum CBD?

Thank you!


Scarlet Palmer

Hi Spyros,

I asked our CBD expert and this is the reply: " is made, quite unfortunately, from isolates since full-spectrum is rather tough for e-liquids at the moment. It would take more steps to clean up extracts from unwanted oils, separating each and every component before putting them back again into a ‘cleaned mix’." He does go on to say though that it might be possible to discover a straightforward way of doing this in the future, which would be "a game changer for e-liquids".

I hope this fully answers your question, and that you continue to enjoy our blog.

With best wishes,




i would like to know if anyone could tell me how high the percentage of thc is in your cbd liquids since the laws are pretty strict with that in some areas.


Scarlet Palmer

Hi Abby,

Thank you for your comment. There is less than 0.05% THC in our CBD products, ensuring that they comply with Dutch law. I hope this answers your question. You may also find this video, on how Sensi Seeds produces CBD oils, interesting.

With best wishes,

I want to know if your e-liquid CBD oil is cut with vitamin E Acetate, the component apparently related to the ilness/deaths in USA.

Kind Regards
