CBD Explained

Ok, let’s be clear about it... Cannabis, Marijuana and Hemp are not the same thing.

Canabis a family of plants with two major classifications, named Indica and Sativa.
Marijuana can be part of the Indica or Sativa family, Hemp on the other hand is part of the Cannabis Sativa family.
As Hemp and Marijuana are both a member of the Sativa family, they have certain similarities, however they are very different products. 

You can compare them with oranges and lemons, they are both citrus fruits, but still very different.  
- Marijuana plant:
High levels of THC (THC is the ingredient in cannabis that has 'psychoactive' effects) ==> Not legal
- Hemp plant: Very small traces of THC (less than 0.2%) ==> Legal CBD

CBD oil is not to be confused with (medical) marijuana or cannabis oil. Marijuana and cannabis oil are sourced from different strains of the cannabis plant and contain much more THC, which will cause a 'high'.

Medical marijuana, or cannabis oil, can be prescribed by doctors as a licensed product, however, it is illegal to be on general sale in the UK. Medical marijuana contains controlled levels of THC and it is used to help people with conditions such as MS. 

CBD in the form of a nutritional supplement has been legalised in the UK, because it only contains trace amounts of THC, and not enough to cause the ‘high’ associated with marijuana. CBD is completely legal and safe to take.


CBD is short for CannaBiDiol, which is a chemical compound that interacts with cannabinoid receptors in your body. CBD was already identified in the 1940s, but with the rise of weed and opiodes, we moved away from it and CBD got pushed to the background.

CBD is extracted from the buds and flowers of a hemp plant, and these don’t contain THC. It is the healthy aspect, but without the high and tiredness that comes with THC.

CBD and THC are two of more than 100 cannabinoids that exist in the hemp plant. They have a similar structure, but not the same effect on your body.
Both cannabinoids interact differently with your body and although there is still a lot of research to be done, early studies seem to show that cannabinoids can promote health and wellness in many different ways.

CBD has the same chemical derivatives as THC, but not all of them, so you can get the same health benefits as from marijuana, without the high or addictive effects.
THC is the component that gives the ‘high’ in cannabis, CBD is the non-psychoactive cannabinoid in cannabis and doesn’t give a high, it doesn’t give you the munchies or any tiredness.

CBD is oil soluble and mixed with either hemp, coconut or olive oil to enhance absorption and this mixture is know as CBD oil.
On top of that, CBD oil in the UK has to be less than 0.2% THC, so it gives you all the good things, without the harmful effects of THC.

CBD has become more and more popular in the last couple of years after extensive scientific research in America on the potential health benefits. It is a naturally sourced ingredient, which is believed to have a lot of health benefits, but without making you ‘high’ or addicted to it.
In a highly regulated industry, there is no room for any misleading promises or health claims around CBD oil, however there are so many resources online explaining the huge popularity rise of CBD since 2018, so make sure to do your own research into this amazing ingredient as well. 


Although both oils are made from the Hemp plant, CBD oil is made from the buds and flowers of the plant and not from its seeds like hemp oil.

Professor Roger Pertwee, from the University of Aberdeen, who pioneered early research on the effects of cannabis in the 1960s and 1970s, elaborates: "CBD oil is oil that contains either pure CBD or a CBD-rich cannabis extract. Hemp oil could well contain a lot of cannabis that may or may not include small or larger amounts of CBD."


First things first... Your body is naturally meant to process cannabinoids and therefore has its own receptors in the central and peripheral nervous system. These receptors all together are called your endocannabinoid system (ECS).

Your body naturally produces cannabinoids (aka endocannabinoids) and plants produce cannabinoids (aka phytocannabinoids).
When cannabinoids are absorbed by your body, they will bind to the receptors in your ECS. 

When it comes to cannabinoids, you might have heard of CB1 and CB2 cannabinoid receptors before. They can both be found in your whole body, but...
CB1 receptors are mainly found in your brain, your central nervous system and how you perceive pain...
CB2 receptors are mainly common in your immune system, affecting inflammation and pain.
CBD oil won’t affect CB1 and CB2 receptors directly, but will influence your body to use more of its own endocannabinoids, which might positively affect your brain, your immune system, the way you manage pain and the inflamation levels in your body.

So, endocannabinoids exist naturally in your body and the ones extracted from the hemp plant are called phytocannabinoids and will interact with your brain, your nervous system and your immune system when they enter your body.
These phytocannabinoids will either mimic or help increase the activity of the endocannabinoids produced in your own body.
By taking phytocannabinoid supplements liked CBD oil or capsules, you are helping your body making optimal use of the endocannabinoids in your system.

Quality Quality Quality!

There can be a huge difference in quality between different CBD oils.
To know that you have good quality CBD oil, first of all, you need to look for a lab tested full spectrum CBD product, derived from the whole plant and not just from isolates. Isolates are an incomplete CBD profile and won’t give the same amazing results as full spectrum CBD does.

Secondly, you need to check how the CBD has been extracted. The best way is using a non-toxic CO2 extraction from organically cultivated hemp plants.
This process ensures a high-potency product, that is batch tested in a lab, without impurities and with just a trace of THC (less than 0.2%).

Third and final point to watch out for is the addition of food grade hemp oil, which results in optimal absorption by your body.

You can find CBD oil practically everywhere these days, however Professor McGuire (Professor of Psychiatry & Cognitive Neuroscience at Kings College, London) says it is easy to get confused about what exactly it is that you are buying: "The products sold in health stores often contain very small amounts of CBD, and may also be mixed with other compounds derived from cannabis. In contrast, the CBD that has been found to be effective in clinical trials is pure CBD, and has a much higher dose."


The short answer is NO, CBD is not addictive.
The World Health Organisation did a 6 weeks study and found out that CBD is non-addictive.
You can take CBD for a number of days/weeks/months and stop it the next day and have no withdrawal symptoms.

People develop an addiction to Marijuana-related products because of the reliance to the psycho-active ingredient THC, which causes the ‘high’ people get from using Marijuana.
CBD comes from the Hemp plant, not the Marijuana plant. The Hemp plant only contains trace amounts of THC (less than 0.2%), which is not enough to create that high. Therefore you can rest assured, you will not become addicted to CBD and there will be no withdraw symptoms if you stop taking it.

Even when you would stop using CBD from one day to the other, you won’t notice any ill effects.
What can happen of course, is that whatever condition you were taking CBD for will return and you will feel less good/healthy again.
For example: if you were taking CBD for anxiety, your symptoms could of course come back when you stop taking it and you are not taking any other medication for your anxiety.


Do not use CBD during pregnancy or breastfeeding. Although it could be that CBD is fine to use during pregnancy or breastfeeding, in-depth studies around pregnancy & CBD are still in their early stages.

The effects that CBD could have on an unborn baby or on a newly born (through mother milk) are unsure, so better not to tempt faith and avoid CBD until your little one is born or until you have stopped breast feeding.


CBD is believed to be completely safe and rarely shows any negative side effects.

When you are taking any (prescription) medications, we do advise to check with your doctor if CBD will affect your medication as it can prevent ‘hepatic drug metabolism’.
This could mean that the medication won’t be metabolised and broken down by your liver, therefore the medication won’t be absorbed by your body.

The research into CBD is still young and more data is needed, but both trials with animals and humans reported that a very small amount of subjects experienced tiredness, light headedness, diarrhea, changes in appetite/weight or dry mouth when taking high dosages of CBD (+1000mg).
Most of the people that use CBD don't show any side effects.

If you would experience any discomfort or side effect, just stop using CBD and see if the side effects go away. Use common sense and if in doubt, ask your GP or practice nurse for advise.


Some people like it, some people don’t... To be honest, it all depends on personal taste. [We know, not helping much, haha]

CBD oil has an earthy taste and can differ slightly in taste depending on the oil it is mixed with.
JellyFish CBD oil has a soft earthy taste, but we don’t think it tastes particularly strong or badly. We kind of like the taste and think it is soft and subtle.

If you really don’t like the taste of CBD oil, then you can always go for our JellyFish CBD capsules here. They get absorbed by the body a bit slower, but have the same effect as tinctures (drops).


    First of all, there is no one size fits all when it comes to taking ‘the right’ dose of CBD.
    Every body is different and we all have different health conditions, so you will have to find out ‘your ideal dosage’.

    There are guidelines on how much you can take (between 5 mg and 20 mg to start with), but it is up to you to find your unique dose, that sweet spot that gives you the relief you are looking for. Listen to your body and adjust accordingly.
    Just keep in mind that if you are taking any other prescribed medication that you check with your GP first, to avoid contra-indication.

    Check out the next questions for more information about dosage. 


    We know, we were too initially when we started our own CBD journey, so we tried to make it as clear as possible in our explanation below.

    When you buy CBD oil and you are not sure what you should go for, the first thing to look at is the mg and the total amount of oil in a bottle. The mg indicates the amount of CBD you will be ingesting.

    So what about the percentage then? The percentage on the bottle indicates the concentration of CBD, so the potency of the CBD oil (the amount of CBD vs oil).
    Percentage is not the best way to choose a CBD product.
    For example, if you have 2 bottles of 30 ml, one with 15% and the other one with 25% of CBD, the 25% could only have 250mg of CBD and the 15% 450mg.
    This would make the 15% bottle more interesting as each drop out of that bottle will have a higher amount of mg of CBD than the 25%.
    The percentage on a bottle is more for the manufacturers to know how much CBD they are putting in a bottle, then for the consumer.

    So, what you need to ask is: “How much CBD will I get PER SERVING?”

    If you have a good brand of CBD oil, it will be indicated on the label how much mg is in the bottle and even how much mg you get per drop/serving. Some companies make it hard and not as straight forward, in that case you can calculate how much is in a drop yourself [if you want to spend your time doing that ;) ]

    1. Look at the total mg in the bottle
    (If it is not on there, it is probably because they don’t know themselves and that it hasn’t been tested in a lab. You really want your CBD oil to be tested, so that you know what you are using.)
    2. Look at the total amount of liquid in the bottle
    3. Then divide the total mg CBD by the total amount of liquid, this will give you the mg/ml
    4. 20 drops equal approximately 1ml, so a single drop is about 0.05 ml
    5. Now multiply 1 drop = 0.05 ml with the mg/ml from the third point and this will give you the amount of mg CBD per drop. That way you can determine the amount of drops you need to take.

    Example: When you have a bottle of JellyFish CBD Oil 15% Full Spectrum 30 ml 
    1. The total amount of CBD in the bottle = 1500 mg
    2. The total amount of liquid in the bottle = 30 ml
    3. 1500 mg / 30 ml = 50 mg/ml
    4. 20 drops = 1ml, so 1 drop = 0.05 ml
    5. 0.05 ml x 50 mg/ml = 2.5 mg / drop
    => So if you want to take 10 mg of JellyFish CBD oil, you need to take 4 drops of CBD oil.

    It is recommended to take 10 mg when you start out and increase it every week with an additional 10 mg until you find your sweet spot.
    Some recommend the maximum daily amount at 200 mg, but there are no reports of serious side effects at higher doses. 

    Everyone takes CBD oil for different reasons and depending on the desired effect, different amounts need to be ingested.
    Some people just take it to help their body function better and then the most common dosage is around 20 mg per day.
    Other people use it to manage pain and have to increase their dosage until they achieve the desired effect.
    Once you have found your ideal dosage, you just maintain it. If you feel you will benefit from a higher dose, then you just increase it every week (with 10 mg at a time) and see how you go.


    You have CBD oil and CBD capsules.
    When it comes to the capsules, you just swallow the amount of capsules depending on the amount of mg of CBD you want to take. Each JellyFish CBD capsule contains 10 mg of CBD.

    When it comes to the CBD oil in tinctures/drops, you just apply the amount of drops corresponding with the amount of mg of CBD you want to take.
    You apply the drops under your tongue, hold them there for a few seconds (30-60 seconds), so it can be absorbed better and then you just swallow them.

    Each drop of JellyFish CBD oil 15% - 30 ml and JellyFish CBD oil 5% - 15 ml contains approximately 2.5 mg per drop, so if you want to take 10 mg of CBD, you just put 4 drops under your tongue.

    If you are taking any prescribed medication or have any medical conditions, we recommend that you consult your doctor/GP or pharmacist before taking supplements or vitamins.


    We kind of like it, but some people don’t like the taste of CBD oil.

    If you are not too crazy on the taste, you can go for JellyFish capsules. They can also be more convenient to take as you don’t need to count the amount of drops or carry around liquids if you travel a lot.

    Capsules can be absorbed a little bit slower by the body than drops under the tongue, but in the end, they will have the same effect. What counts is the mg per serving and how many drops or capsules to take.

    Also check the quality of the CBD you are taking, as that is the most important thing. (You can read more about quality in question 5.)


    Not at all, it can stabilise your blood sugar levels, so you could experience less cravings and if you take it to decrease nausea, it could increase your appetite as your nausea is gone.

    Other than that, it will just support your normal appetite.


    No, it doesn’t make you high as the THC levels in JellyFish CBD are below 0.2%.

    Often people taking CBD don’t experience the ups and downs so much as they otherwise do. It will bring you to your middle range, your normal calm state.

    So you don’t have to worry, it won’t make you feel so relaxed that you want to fall asleep and it won’t give you a high or make you hyperactive either.


    Some people take it continuously, others take it as and when.

    If you are taking it to ease pain of arthritis for example, you will probably want to take it on a regular basis to keep the pain away.
    If you take it to ease of stress, you can just take it when you are experiencing more stressful days and leave it when you are having less stressful or even stress-free days [if that's still possible these days, haha].

    CBD does have a bit of a cumulative effect, so if you take it more continuously, you will notice the benefits of it on a more regular basis.

    The bottom line is, that you can take it anyway you want and experiment what suits you best, either if it is periodically or consistently. Feel free to see what works best for your body.


    We are no doctors and this is something you will need to discuss with your own GP or doctor.

    The only thing we can say is that some people gradually can replace their prescribed medication with the use of CBD oil, with for example anxiety or depression. As CBD can help overall mood and depression, it could work for you, but it doesn’t work for everybody.
    Again, we are no doctors and you will need to ask the advice of your doctor first.


    Yes, definitely... It will probably actually help you focus as it can take away whatever can distract you like pain, anxiety, depression, ...

    You can do all the things you would normally do, maybe even better...


    It is, as long as CBD is legal in the country or countries you travel to and travel through.

    So, always check the legality of CBD in the countries you will be passing through and your destination country.

    CBD with less than 0.2% THC (the psycho-active ingredient in cannabis) is legal in the EU (there are exceptions for Slovakia and Denmark) and it is legal in the UK, so you can rest assured to take your JellyFish CBD oil through most of the EU and the UK.

    At the time of writing this answer, Slovakia hasn’t legalised CBD just yet, so don’t take your CBD there as it could get you in trouble.
    In Denmark, you need permission of a doctor to take CBD, without it, you are not allowed to take CBD.
    In the US, hemp-derived CBD with less than 0.3% THC is legal in all of the states, it must adhere to the shared state-federal regulations and it must be grown by a licensed grower. There are differences for each state though, so better double check before you travel.


    With concentrate you lose the benefits of the whole plant, it is not just the CBD that gives benefits, but also the other parts in the plant.
    Extract is from the whole plant, which gives you these benefits that you won’t find in a concentrate.

    There are three types of CBD products:
    - Full Spectrum: this is the most pure form of CBD products. They contain CBD and less than 0.2% THC, but they also have other cannabinoids like: CBDV, CBC, CBDA and other phytocannabinoids.
    - Broad Spectrum: they contain the same as full spectrum products, but without the THC.
    - Isolates: they are exactly what it says, only the CBD has been isolated from all the other plant matter and the cannabinoids.

    If you want to have all the benefits of CBD with all its compounds, you better go for the full spectrum, or the broad spectrum if you don’t want any THC at all.

    Just think about it this way. If you can chose between CBD oil with 50% CBD that has been heavily processed, and extracted with butane or CBD oil with “only” 12% CBD that has been extracted with CO2 and kept away from heat so that it maintains its natural mix of nutrients and terpene profile, then the second one will have preserved most of the benefits for your health... and that's the one you want to go for.

    Quality is key when buying CBD, also check out question 5. Why is there such a big price difference between different CBD oils?

    Also, if a company’s main selling point is the percentage, then avoid them! Read all about it in question 11.


    CBD is believed to be able to treat a large range of different problems.

    Our body is CBD deficient, we have cannabinoid receptors ready to be filled up with CBD and reap the benefits to your health.

    A World Health Organisation report found that it may help to treat the symptoms of following conditions/diseases successfully: Alzheimer's Disease, MS, Parkinson's Disease, (chronic) pain, anxiety, depression, cancer and diabetic complications.

    While a large part of the research into the effects of CBD oil has been based on animal studies and anecdotal evidence, studies on humans are in their early stages and showing promising results.

    Nevertheless, some very clear benefits have been highlighted already:


    Different studies have revealed that the use of CBD oil can be helpful in reducing anxiety, stress, depression and even the symptoms of PTSD, and could be used as a natural remedy.

    A study from 2011, published in the Neuropsychopharmacology journal found that people suffering from social anxiety disorder experienced significantly less anxiety and discomfort during a public speaking test when given 600 mg of CBD oil, as opposed to a placebo.

    Other studies have researched the effect of CBD oil as an anti-depressant and have shown that it could improve symptoms of post-traumatic stress disorder (PTSD) in children.

    Professor Philip McGuire, Head of Department of Psychosis Studies at King's College London, claims CBD has the potential to treat mental health problems.
    He said: "CBD may be useful as a treatment for patients with psychotic symptoms like paranoia and anxiety, as well as depression. The effectiveness of CBD in this area is currently being evaluated in clinical trials at King's College London."


    As CBD can help you to bring you to your natural calm (not tired or hyper), it makes it easier for the body to relax and for you to fall asleep. It can work as a natural soothing remedy, helping you to sleep better.


    Several studies, both on animals and humans, have looked into the link between CBD and pain relief. The ability of CBD oil to reduce inflammation and interact with your neurotransmitters are at the basis of this research.

    CBD oil is believed to relieve (chronic) pain from multiple sclerosis (MS), arthritis and even fibromyalgia, as it binds with pain producing brain cells and therefore changes their perception of chronic pain in your body.

    One study showed that CBD and THC can improve pain management for people suffering with rheumatoid arthritis.

    Another study found that multiple sclerosis sufferers, treated with a combination of CBD and THC for a month, experienced increased mobility, less muscle spasms and reduced pain.

    But how... ? 
    CBD can help pain management, regulation and modulation of sore joints and muscles, even of painful organs and glands.
    The pain you are experiencing can be caused by imbalance and lack of endocannabinoids (ECS) in your body. By replenishing these ECS, you can regulate your central nervous system and how they respond to pain.

    CBD isn’t necessarily going to solve the root of your pain, but it can bind itself to receptors that block certain compounds that trigger pain and in that way can reduce the pain you are experiencing and give you a better quality of life.


    As mentioned in question 4. Endocannabinoid... what?, your body is naturally meant to process cannabinoids and therefore has its own receptors in the brain, spinal cord and all your immune cells. These receptors all together are called your endocannabinoid system (ECS).

    When it comes to cannabinoids, you might have heard of CB1 and CB2 cannabinoid receptors before. They can both be found in your whole body, but...
    CB1 receptors are mainly found in your brain, your central nervous system and how you perceive pain...
    CB2 receptors are mainly common in your immune system, affecting inflammation and pain.

    Inflammation is the response of your body to any kind of trauma or immune response. The inflammation pushes on the nerves in your body which causes pain.
    This inflammation causes your cells to become overactive and your body will cause an immune response which will lead to more inflammation, it’s a vicious circle.  

    CBD is believed to lower inflammation levels, restoring the balance within your body.
    Cannabinoids from the hemp plant will help your endogenous cannabinoids to function more optimally and can effect the anti-body production in the immune system. 

    Chronic inflammation is something that can hurt the body beyond repair, it can contribute to diseases like: cancer, Alzheimer's, auto-immune disease, heart disease etc.
    Research has revealed that CBD oil can reduce this chronic inflammation, promote healing and help the body to create more endogenous cannabinoids and find balance again.


    As we explained in our blog post about CBD and cancer, stating that CBD will heal cancer is exaggerated and there is no proof of it at all, but it is believed that it can slow the growth of certain cancers and reduce the symptoms associated with cancer treatment, like nausea and vomiting that can come with chemotherapy.

    Read more about it here: Cannabis Oil (CBD) kills Cancer Cells


    It has been shown that CBD can have great effects on reducing seizures (like with epilepsy) and spasms (like with Parkinson's).

    Although clinical trials and experiences around this subject have been with higher than the average amounts of CBD, they have been found to be highly effective in the treatment of certain types of epilepsy.

    Further research into this subject will have to determine the dosage and effects on different diseases like Parkinson's and epilepsy, but it definitely is promising.


    As CBD stabilises the cells in your body, bringing them to their natural, most stable form, it is believed that it can also improve heart health by lowering blood pressure and reducing cholesterol.


    CBD can help you to reduce stress, anxiety, pain etc. It regulates blood sugar levels and so will control your cravings better (less crashes and spikes of your blood sugar).
    It could also reduce cortisol levels and in that way help you to lose weight.

    We are not saying that CBD is a ‘new’ magical weight loss product, but it might help you to regulate those cravings and be an aid in your weight loss.


    As there is a very tiny amount of THC in JellyFish Full Spectrum CBD oil, depending on the amount you take, there is a small chance of it showing up on a drug test.

    We do know people that take it and that get tested at work regularly, where it doesn’t show up in the results. It all depends on the criteria of the drug test and how much CBD that person takes.

    It usually takes around 1 to 2 days for CBD to disappear from the body.
