What You Should Know About CBD E-liquids


What’s a CBD E-liquid?

E-liquid – also named as e-juice is the liquid that fuels an e-cigarette. It is vaporised by the battery powered atomiser (e-cigarette) to imitate the sensation of smoking.  It’s normally composed of 2 primary ingredients –an atomising base (PG-VG) and the flavouring.

With e-cigarettes becoming very popular lately amongst cigarette smokers, the use of vaporizers & E Liquid has also branched out into our world of health and is considered the most convenient ways for taking CBD.

During vaporisation, CBD enters your lungs and diffuses directly into your bloodstream rather than passing through your gut and liver. This avoids “the first-pass effect” altogether, allowing nearly four times as much CBD to enter your circulation for a maximum bioavailability of roughly 50 to 60 percent. That means for every 100 milligrammes of CBD that you vape, 50 to 60 milligrammes will actually reach your bloodstream.(the oral bioavailability of CBD is roughly 15 percent). Basically, you can achieve the same beneficial effects with a much smaller amount of CBD.

CBD E-liquids Bases

When it comes to e-liquid, two concepts constantly crop up: PG and VG.
This can seem confusing to beginners, but knowledge of these two ingredients can greatly enhance your vaping experience.  Both e-liquid bases, outlined below, are equally safe and approved by the FDA.

• PG (Propylene glycol) – A clear, colourless liquid which is usually used as a flavouring carrier in food products. It has been utilised in asthma inhalers and nebulisers since the 1950s. Propylene glycol delivers the flavour very well and provides strong throat hit.

• VG (Vegetable Glycerin) – A colourless, odourless, and tasteless viscous liquid. VG is exclusively derived from plants (soybeans or palm). E-liquids can be made from up to 100 % VG or PG, however, nowadays e-liquids are usually mixed to take advantage of both. Vegetable glycerine is thicker than Propylene glycol and it doesn’t dissolve the CBD as good as the PG. It produces better vapour than PG and is a great sweetener as well.

Nowadays you can pick from so many flavours from Creme Brulee to a breakfast cereal, choosing is like standing in the middle of a candy store.

E-juice usually contains 5 – 20 % flavour. E-liquid manufacturers will use either natural or artificial flavouring, some vendors go as far as making their own extracts.

For example, the Harmony Cannabis Originals e-liquids have their flavours extracted from terpenes of the original cannabis strains.

CBD e-liquids

When choosing e-liquids, you should pay attention to its composition. You don’t want your e-liquid to contain diacetyl because accumulated exposure to this volatile compound can cause severe bronchiolitis.

        Hi Clara, your shop has a great selection!!

        Im interesred to sell comission based. I have quite an extensive social network and believe I could boost your sales while not cannibalizing in location.
        Did you work commission based before. My Im is to work with max 2 top notch shops so I have a rathersmall selection to sell – but all quality products.
        Second question, is it possible to create a link from my page to your shop and earn for clicks? I only have experience on referrals system on DN marketplaces. I could sell over IG, I suppose but the prmos they offer are very expensive…..the market for cbd based products is huge i m confident

  3. Roy says:

    Hi i have a question about the crystal cbd. if I buy the 500 mg of cbd what is the percentage I’ll have to ad In my eliquid to get 20% mg on 100 ml Liquid ?

    Kind regards Roy

    1. Clara says:

      Hello Roy, thank you for your interesting question 🙂 Be aware that Harmony strongest concentration is 10% CBD in 10ml bottles or 1000mg of CBD or 100mg/ml. In order to arrive at a concentration of 20% (twice higher than Harmony’s highest concentration) in 100ml bottles ( 10 times bigger than Harmony 10 ml bottles), you will need to add 20 000 mg of CBD in your 100ml bottles (200mg/ml) or 20g of CBD. Let me know if you have any question! Have a great day

  4. Malcolm says:

    Hi Clara,

    Do you know if I can use harmony cbd liquids in my endura t22 vape? Many thanks for your help 🙂


    1. Clara says:

      Hello Malcom! Thank you for your message 🙂 I have a great news, Harmony CBD e-liquids should be vaporized like any other type of e-liquids with a PG/VG base and so are suitable with your endura t22 vape! Enjoooy!

  5. Nova_Denmark says:

    If i want to try neutral base with sub-ohm vape, then how should i mix 100mg -10ml in for example 50ml 70vg/30pg? 🙂

    1. Clara says:

      Hello Nova! Thank you for your interesting question 🙂 When trying to determine the correct amount of CBD to mix it’s best to start small. With CBD, you can easily scale up just a few milligrams at a time to meet your personal needs. You can begin to mix a quarter or half of the 100mg – 10ml in your base. If you feel it is not enough then you will be able to go up gradually. Also, It is important to remember that CBD doesn’t dissolve well in VG and so always mix first CBD with PG before mixing with high VG e-liquids! I am staying available for any further question. Have a great day!

  6. Gabriel says:

    I’m very new to vape, I’ve tried for few days a SMOK e-cig with original CBD e-liquid but it was leaking all over including into my mouth when vaping so I got a bit traumatized and i stopped. I’m willing to give it a second chance, maybe with your starters kit with og kush flavour. I’ve just got one question, can I use the CBD OG kush e-liquid alone in the pen or I still need to mix it with another liquid as a base? Thanks in advance for your help.

    1. Clara says:

      Hello Gabriel! We are sorry to hear your misadventure with your e-cig SMOK. It seems that the tank was drowned, maybe the fill limit was exceeded? Harmony CBD e-liquids, including Harmony OG Kush, are ready to be vaped and don’t need to be mixed. Moreover, we wouldn’t advise you to mix Harmony CBD e-liquids with another e-liquid since you will lose the unique flavour of it. If you have any other question, please don’t hesitate to ask! Have a great day

  7. Jonathan says:

    I haven’t tried VG eliquid, I want to try it, I am not sure where I can get one. I have visited a lot of eliquid stores online, they don’t have it.

    1. Clara says:

      Hello Jonathan! It is actually not possible to make 100% VG CBD e-liquids as CBD doesn’t dissolve in VG. This is why Harmony CBD e-liquids are dominant PG as CBD need PG to be vaporized. Don’t hesitate to ask if you have any other question. Have a great day!

  8. Lucy says:

    Hello i want to buy some of your products but i would like to that legal in France?

    1. Clara says:

      Hello Lucy! Thank you for your interest 🙂 CBD is not a controlled substance in France, which means we can currently sell them all over Europe (and beyond!). Have an amazing day!

  9. Tiago says:

    Hi Clara,

    can I mix the OG Kush liquid with a pure nicotine base?

    Thank you in advance for your answer,



    1. Clara says:

      Hello Tiago 🙂 Thank you for your message! I have a great news for you, you can mix Harmony OG Kush with a pure nicotine base without perishing the CBD. Enjoy 😀

  10. Cristian says:

    Buenas, que contenga más o menos CBD influye en el sabor a cannabis a la hora de vapear?

    1. Clara says:

      Hola Cristian! ¡Gracias por su mensaje! La concentración de CBD no influye los sabores de e-liquids Harmony 🙂 Que tengas un bon dia!

  11. Chris says:


    I am considering vaping CBD. I already vape nicotine eliquids as I am an ex-smoker. I just wanted to enquire, can I use CBD eliquids in a normal tank that I would use for vaping nicotine liquids? I had been told that I would need to get a special CBD vaporiser pen.

    1. Clara says:

      Hello Chris! Great to hear your interest in CBD! No, you do not need a special device or tank to vape Harmony CBD e-liquids. You can use Harmony CBD in any vape setup, including clearomizers, sub-ohm tanks, and RDA’s 🙂 If you have any other question, please don’t hesitate to ask! Have a great day

  12. Pete smith says:

    Hey, is it possible to get high of the cbd e liquid

    1. Alana says:

      Hey Pete! Great question, Harmony e-liquids will not get you high. With our CBD e-liquids, enjoy a pleasant cannabis (or hemp) flavor and, at the same time, be sure about what you are vaping thanks to high-quality control standards.

  13. damqnski says:

    Hello. I just found your website, totally random. Looks very promising. My question is, will I get the health benefits as if I was taking regular cbd oil sublingual? I saw some 1star reviews on your FB page saying that it won’t relief pain, is that true? Thank you!

    1. Magda says:

      Hi there, thank you for your message! At Harmony, we don’t produce or sell CBD oil (the kind you would take sublingually), we make CBD e-liquids with terpenes in a range of great flavours. Our CBD e-liquids are intended for vapers or smokers looking to get into CBD vaporisation and should not be considered as a medical product.

      If you’d like some more information about CBD vaporisation please feel free to ask 🙂

  14. Sally Baker says:

    Hi, ive been using E liquid vape for over a year now as stopped smoking. Ive been given Harmony CBD 100mg – 10ml vape to try because of my pain and insomnia. Please could you tell me how much I should mix with my 0.8 e liquid in a 2.5ml tank please?
    Regards Sally

    1. Magda says:

      Hi Sally, thanks for reaching out 🙂 Harmony CBD e-liquids are a great alternative to quitting smoking but shouldn’t be thought of as a medical product.
      To give you the best advice, may I ask if you’re referring to the Harmony Pure Base 100mg (flavourless) or one of the Harmony CBD flavoured e-liquids?

      If you’re adding Harmony Pure Base to another e-liquid, you can try 1-2ml first. If you’re adding a flavoured Harmony e-liquid, then you can fill up to the maximum line on your tank.

      Hope that helps 🙂

  15. D. says:

    Hello. I have the e Juice New York Diesel 100mg cbd. It is very cloudy and harsh. Is this normal or not?

    1. Alana says:

      Hey Dimitri, thanks for the question! Occasionally our liquids can be clouder which is simply due to the CBD interacting with the base but is totally normal! The varying levels of CBD can be harsher for some depending on the individual so we recommend starting low and seeing what works best for you! Hope that helps ?

  16. rushyd05 says:

  18. Michelasso says:

    Hello, I am not a smoker, I have quitted smoking more than 15 years ago. I would like to try your Original Hemp CBD e-liquid just to see if it could help me to relax myself.
    I thought to try the 600mg version, I am only afraid it could hurt my throat, could you tell me if different concentrations of CBD have different impact in that sense?
    Also, are there any specific features that the ideal e-cigarette should have to full exploit CBD properties?

    1. Alana says:

      Hey Michelasso! The varying concentrations don’t change the taste but can be a bit harsher when the concentration is higher, it all depends on the persons’ sensitivity as well. We recommend when vaping our liquids to keep the wattage between 10-30 watts and the temperature between 150-180 degrees Celsius. Hope that helps!

  19. gianpieroscolaro says:

    Thank you for the fast shipped , i take pure base cbd, thanks from Italy

    1. Alana says:

      Glad to hear it got there quick and you’re already enjoying them 🙂

  20. Ydna says:

    Can I have a simple answer if any of your CBD e-liquids helps to beat insomnia and relief severe back pain. In case of positive answer/s, which one is recommended, taking into account that both of my described problems above are pretty severe.
    Thank you for your prompt and clear answer.

    1. Alana says:

      Hey Ydna, Our products are not medicinal products and should not be used to treat, cure or diagnose any ailment or illness. Hope that helps!

  21. D says:


    Is it toxic to eat e-liquid?
    I got one, but i don’t smoke and i just want to drop it in my mouth.
    Can I do that? And how much should i take, i know that u need more than if u smoke it.

    1. Alana says:

      Hey There, We do not recommend dropping our liquids under your tongue. They are vaping products and should not be eaten!

  22. Marcus says:

    Hi, I have recently bourt a bottle of cbd e liquid and I have a question about how much your meant to vape. I’d usually vape my e cigarette quite regularly throughout the day. Would you do the same with cbd? Or are you meant to just have a few tokes? Thank you

    1. Susie says:

      Hello Marcus! Great question, our e-liquids are all-day vape. The amount of CDB you consume is completely to your personal preference.

  23. Mateus says:

    Hello. I would like to ask about contain of CBD e liquid. There is only kannabidiol or there are also any others kannabinoids? Best regards

    1. Susie says:

      Hey Mateus, glad you asked! All of our products contain CBD isolate and are not considered to be full spectrum. Full spectrum products contain a profile of cannabinoids at varying levels, not only CBD.

  24. Arthur says:

    I bought og kush vape pen and it’s taste kind of chemicals i think it’s because of high amount of PG,i will buy again of VG will dominate in your e-liquid as PG is pretty unhealthy.

    1. Susie says:

      Hey Arthur, Thanks for your message. We understand but due to CBD crystallisation the PG/VG ratio is 80/20, for the best CBD vaping experience. It’s more likely to have the ratio 50/50 when there are small amounts of CBD concentration but it’s not possible for 100mg,300mg, and so on. Hope this helps! Feel free to email us if there is more you’d like to know about.

  25. Alex says:

    Newbie to vaping – got myself a EGO AIO with 0,6 Ohm coils and Pure Base 1000mg as I only want to use it occasionally (once a week).
    I primed the coil on both sides and let it rest for 15+min but somehow I get an increasingly burned taste. Already switched the coil but it starts to taste burned after a few times inhaling. I only inhale for 2-5 seconds and start the coil 1s upfront and inhale until 1-2s after releasing the power button – “burn”-phase only 2-5s.
    What am I doing wrong?

    1. Alex says:

      From what I read accross this site you should at least mix this stuff to a ratio of 80% PG (in my case pure base) and 20% VG (any elquid based on VG) – then it should be vapable?

      1. Alex says:

        It was a bad vape – the Ego Aio is quite bad. I didn’t bought it on this site which might have been the problem. Got some professional advise and problem solved.

    2. Alana says:

      Hey Alex, Glad to see you got it sorted in the end! For the Pure Base just be sure that if accounting for the 80% only with the base you take into consideration the amount of PG in your other e-liquid. Reach out via email if you continue to have issues!!

  26. Kevin says:

    Is there thc traces in your liquid would be great if there was thanks

    1. Susie says:

      Hi Kevin 🙂 All of our products contain CBD isolate with no traces of THC. Send us an email for a full certificate of analysis on all our products.

  27. Greg says:

    Hi I’m new to vaping and CBD, what strength would you recommend for my first order? What are the differences between the strengths of CBD?

    Thanks 🙂

    1. Susie says:

      Hey Greg 🙂 Welcome and thanks for your comment! When vaping CBD we recommend starting low and gradually increasing. Daily vapers will prefer 30mg CBD or 100mg CBD as they vape often and need affordable e-liquids. Occasional vapers will prefer the 300mg for a more concentrated dose of CBD per draw. Experienced CBD users will tend to buy higher concentrations such as the 600mg or 1000mg Pure Base. Hope this helps, feel free to email us if you need further information, we are happy to help.

  28. Ulei CBD says:

    We are very happy with your products:)

    1. Joe Marris says:

      Hi there,

      We love that you’re happy with our products – thanks so much for writing in!

  29. Amy says:

    Two questions. First do your liquids contain victim e? There’s research going into what vaping vitamin e can do after a few deaths in Kansas.
    Also can you mix these e-liquids with other vape juice?

    1. Marianne Lalande says:

      Hi Amy, thank you for your question.

      At Harmony, we do not use Vitamin E Acetate in any of our CBD liquids. We use a mixture of CBD, PG, VG as well as flavourings, none of which contain this vitamin. We also publicly publish our certificates of analysis online frequently to ensure that the concentration of CBD is correct. These can all be found here.

      If you’d like to mix e-liquids, you can try out our Pure Base to add a CBD boost to your favourite e-liquid. I hope this helps 🙂
