What’s the Difference Between CBD Oil and Full Spectrum Cannabis Oil?

Cannabis oil is in the headlines again, especially in the UK. Having lagged behind most of Europe and the US in terms of taking full advantage of the medical potential of cannabis, the UK is now in the throes of considering cannabis rescheduling.

The population is attempting to come to terms with everything from CBD products suddenly appearing in health food shops to full spectrum cannabis oil now being permitted for two children with epilepsy.

All this is taking place against a backdrop of the news that the UK is the world’s largest exporter of medicinal cannabis, shipping out over 2 tonnes in 2016 alone. This figure is dwarfed by the amount produced in the UK in the same year, a massive 95 tonnes. In a twist that would seem far-fetched in a novel, let alone a newspaper, 45 acres of cannabis is being grown by British Sugar.

The managing director of British Sugar is Paul Kenward. He’s married to Victoria Atkins. She’s the UK Parliamentary Under Secretary of State for Crime, Safeguarding and Vulnerability, which means she’s responsible for drug policy. And yet, in the UK cannabis is still scheduled as a Class B drug, defining it as having no medicinal value!

Why is it so important to know the difference between CBD oil and cannabis oil?

There are various important differences between cannabidiol, or CBD, oil and full spectrum cannabis oil. They range from how the two types of oil are made, to their legal status, and most importantly their effects on the human body. It can be tricky to stay on top of all the developments and differences in the rapidly evolving field of cannabis, even in a country where it’s more or less legal.

Potential harm can come from people thinking they can cure serious afflictions using regular CBD products

In the quagmire of partial information, misinformation, and flat-out falsehoods about cannabis that is the state of play in the UK and Europe, it is no surprise that there is confusion about the difference between CBD oil and full spectrum cannabis oil. What is deeply worrying is the potential harm that can come from people thinking that they can treat serious afflictions using regular CBD products.

(The impetus for this article came from a comment, on a news story about full spectrum cannabis oil, from a person who thought they would be able to cure their father’s cancer with 3% CBD oil from a health food shop.)

CBD is an astonishing cannabinoid, but in its current commercially available form it cannot cure cancer, stop epileptic seizures, or accomplish the kind of major feats that full spectrum cannabis oil sometimes can.

What is in CBD oil?

There are obviously many different CBD products flooding the market right now, and generalising about their composition is not as useful to our readers as being specific about the Sensi Seeds CBD range.

The cannabidiol used for Sensi Seeds products is blended with organic hempseed oil, both ingredients sourced from industrial hemp plants grown in the EU. To offer the most convenience, Sensi Seeds CBD oil comes in capsules; mixed with coconut oil, for a milder flavour; and in original form with a dropper for dosing.

The most important component is the cannabinoid CBD, or cannabidiol. CBD is not psychoactive, but it does have relaxing and anti-anxiety properties. The main difference between CBD oil and full spectrum cannabis oil is that cannabidiol is the only cannabinoid in CBD oil.

What is in full spectrum cannabis oil?

Full spectrum cannabis oil, or FSO, contains the complete range of cannabinoids and terpenes that can be extracted from cannabis. These are the components that are known to have medicinal properties, many of which are still being researched and explored. FSO also contains the flavonoids and other compounds that give cannabis its unique flavour profiles.

The main difference between FSO and other extracts such as shatter and wax in terms of the content is that these compounds are carefully included rather than lost during the filtration process.

Legality of CBD oil and FSO

The legality of both CBD and FSO is still being refined, debated and flat-out argued about in various countries around the world. CBD is fully legal in areas of the US where cannabis itself is legal. In the UK and EU, CBD products are legal as food supplements.

However, it is important to note that they cannot be sold as anything other than food supplements without the approval of medicinal authorities, and the certification of the retailer as a pharmaceutical business. In other words, if CBD is a medicine, it has to be prescribed and sold as a medicine.

FSO, since it contains THC, is illegal everywhere that cannabis is illegal. It must be remembered that the production process is also illegal because it involves large amounts of cannabis plants. The UK currently stands at the tipping point of crucial change, catalysed by Charlotte Caldwell. Her 12 year old son Billy needs FSO to control his frequent and potentially fatal epileptic seizures.

She brought a bottle back to England which she had legally obtained in Canada and declared at Customs when she entered the country. Seized at Heathrow Airport, her son’s vital medicine was not returned for nearly a week. It took Billy being rushed to hospital and a huge public outcry for this callous decision to be reversed.

Medicinal applications of CBD and FSO

As already stated, CBD in Europe sits in the awkward position of a substance that is not recognised as a medicine, yet undoubtedly has therapeutic properties. There are currently 2,034 results for research papers on cannabidiol on PubMed, the online resource of the US National Library of Medicine and the National Institutes of Health.

Both anecdotal and scientific evidence indicate that CBD oil can help with an extensive range of aliments including, but not limited to, arthritis, diabetes, multiple sclerosis, post-traumatic stress disorder, depression, and epilepsy. Research continues apace, so it is certain that this list will continue to grow.

Full spectrum cannabis oil is also still under investigation, and also promises to reveal a plethora of medicinal uses. The current evidence demonstrates that full spectrum cannabis oil successfully carries and concentrates the effects of beautifully grown, strong cannabis. Therefore, everything that can be treated with herbal cannabis can potentially be treated with even greater efficacy using full spectrum cannabis oil.

As mentioned above, the characteristic that really sets full spectrum cannabis oil apart from CBD oil (and indeed, all other types of cannabis and hemp oil) is that it contains all of the bioactive compounds of the buds it is made from, so that the entourage effect – a phenomenon that is still not fully understood – is not lost, but concentrated.

This is why it is especially effective for children, as the ease of administering oil is obviously much greater than that of administering cannabis buds, and the dosage can be far more accurately calibrated.

How are CBD products made?

All Sensi Seeds CBD products start with CBD oil, which is perhaps unique among CBD oils in that Sensi Seeds has complete oversight and quality control over every stage of the manufacturing process, from seed to final item. The whole process is detailed here (with a great animation!). A crucial difference between Sensi Seeds CBD oil and other cannabis oils is the extraction process, which is accomplished with supercritical CO2 rather than solvents.

How is full spectrum cannabis oil made?

Cannabis oil (Full Spectrum) and CBD oil: what’s the difference?

Full spectrum cannabis oil is also made without the use of solvents. Because all types of cannabis oil still exist in an unregulated market, it is difficult to say what the standard method is for them. There are methods which use very strong alcohol, and even butane. The latter was used for the earliest versions of cannabis oil but has since been surpassed.

The most modern and effective techniques are the ones that retain all the 500 plus bioactive compounds that ripe buds of cannabis contain, not just the cannabinoids. These techniques and the equipment needed to achieve them are still very limited in their availability. Unfortunately, full spectrum cannabis oil is not something that can be made in a domestic kitchen.

As legislation advances to allow access to more sophisticated and therefore more effective medicinal cannabis products, it is to be hoped that more and more laboratories open up to producing true full spectrum  cannabis oil.

Which one is right for you?

This is the question that, unfortunately, we can’t answer. If you are interested in knowing more about what cannabinoids can do for your health, exploring the many articles on this blog about the medicinal use of cannabis is a good start. This article was specifically written for doctors and other clinicians as an introduction to cannabinoids; it could serve as a good foundation and starting point for discussions with your healthcare provider.

As with all changes you are considering making to your diet or healthcare routine, always consult a qualified medical professional first.

      Hi Victor, Thanks for checking with us, but at this time we don’t sell this product. Here’s a link to the sensi seed website: https://sensiseeds.com/en/cbd-products. Good luck!

    Hi, I liked your note regarding CBD oil vs FSO and I agree with the concept that FSO appears to be more effective than just CBD Isolate. What I do not agree is with your comment on the extraction methods. You are misleading when you talk about the CO2 Supercritical as a better system because you know that after the extraction process you need to add ethanol to the resin for winterization. Even more, the newest CO2 equimpent use now ethanol as co-solvent!!
    It is a pitty that you obliterate a good article with a false statement to gain customer by lying and confusing,

      I’m the author of this article, which originally appeared on the Sensi Seeds blog. The information about supercritical FSO extraction is mainly taken from this article: https://www.leafly.com/news/science-tech/full-spectrum-cannabis-extracts-explained (which I link to) and from internal company information at Sensi Seeds. Possibly you are confusing true FSO with hash oil, extracts, etc as you mention resin, which is not a product of our method?

      Sensi Seeds does not produce FSO, we produce CBD Oil from our own hemp plants so that there is transparency at every stage of our manufacturing process, from seed to bottle. We have no need to mislead our customers, though I appreciate your concern as there are many less ethical CBD manufacturers springing up at the moment.

    I guess the author is confused themselves about CBD Oil, THC Oil and Full Spectrum Cannabis Oil.

    CBD is mostly made with CO2 extraction.
    THC is mostly made with alcohol as the extractor.

    Neither alcohol nor CO2 will get you a full spectrum range.

    You need to extract at different temperatures to get the different goodies in in and you can very much do this at home.

      Hi, Thanks so much for your comments. The author was talking specifically about Sensi Seeds CBD oil and how they make it. She linked to their process at https://sensiseeds.com/en/blog/cbd-products-according-sensi-seeds/ She did say they use CO2 extraction. I suppose she also meant the equipment at Sensi Seeds is more sophisticated than what you would use at home, and with better more consistent results. But also, please note this article is almost a year old. The cannabis field is constantly moving forward and improving!

    CBD will show in certain tests and not in others. Traditional tests that test for THC only may not show up if you’ve taken a hemp derived CBD product.

    Hemp derived CBD products only have trace amounts of THC. Usually below 0.3%. Cannabis derived CBD products with THC in them can show up on your drug test.
