The Entourage Effect

Seeking a great quality CBD supplement is about much more than the content of CBD. At SoSoPure™ we are passionate about the use of whole plant extracts in our products. This refers to whole plant CBD oils, CBD infused oils, balms & creams. Our CBD products contain a wide array of health-promoting compounds found in the natural plant, which includes a spectrum of cannabinoids and terpenes in trace elements. SoSoPure™ Full Spectrum CBD Oil is where you are getting the whole plant and all of its hemp goodness!

Consuming whole plant CBD containing the full spectrum of compounds is preferable. The entourage effect refers to the synergy between all the cannabinoids, terpenes and flavonoids in the plant which work together like an orchestra, each one supporting and complementing each other. While cannabidiol (CBD) may take the lead position, it’s still important that we include all the other components as well, rather than a single CBD isolate.

Clear vs. Pure: How Fallacies and Ignorance of Extraction Misrepresent the Cannabis Flower

Demand for cannabis extracts, in particular vaping products, is at an all-time high. People want good oil, and they want to know something about the quality of it. It is therefore time to take a step back and consider the process from plant to cartridge. What is the current industry standard for cannabis extraction, what constitutes quality and where might we need to make some adjustments?

Right now, “clear” oil is hot. Customers have been led to believe that a pale gold extract is synonymous with the best possible cannabis concentrate, which is not necessarily the case. Producing a 95% pure THC extract with a translucent appearance is neither a great scientific feat nor a good representation of the whole cannabis flower. Moreover, it runs counter to the current trend of all-natural, non-processed foods and wellness products.

“My carrots are organic and fresh from the farmers market, my drink has no artificial sweeteners and my honey is raw, but my cannabis oil has undergone a dozen steps to look clear and still contains butane.”Cannabis is a fascinating plant. It is the basis of our livelihood, but more importantly, it enhances the quality of life for patients. The cannabis plant offers a plethora of medicinally interesting compounds. THC, CBD and terpenes are the most popular, but there are so many more. As of the most recent count, there are 146 known cannabinoids1. Cannabinoids are a group of structurally similar molecules, including THC and CBD, many of which have shown biological activity.

Then there are terpenes. These are the smaller molecules that give cannabis its distinct smell and flavor, over 200 of which have been identified in cannabis4 But wait, there’s more. The cannabis plant also produces countless other metabolites: flavonoids, alkaloids, phenols and amides. All these components mixed together give the often-cited entourage effect.

Current industry standards for cannabis oil extraction and purification stand in marked contrast to the complexity of the plant’s components. Due to an unsophisticated understanding of the extraction process and its underlying chemistry, cannabis oil manufacturers frequently produce oil of low quality with high levels of contamination. This necessitates further purification's and clean up steps that remove such contaminants unfortunately along with beneficial minor plant compounds. If one purifies an extract to a clear THC oil, one cannot also offer the full spectrum of cannabinoids, terpenes and other components. Additionally, claiming purity around 95% THC and being proud of it, makes any self-respecting organic chemist cringe.
Precise control of extraction conditions leads to variable, customized concentrates.

The labor-intensive, multi-step extraction process is also contrary to “the clean-label food trend”, which “has gone fully mainstream”. Exposing the cannabis flower and oil to at least half a dozen processing steps violates consumer’s desire for clean medicine. Furthermore, the current practice of calling supercritical-CO2-extracted oils solvent-less violates basic scientific principles. Firstly, CO2 is used as a solvent, and secondly, if ethanol is used to winterize, this would introduce another solvent to the cannabis oil.

We should reconsider our current extraction practices. We can offer cannabis extracts that are free of harmful solvents and pesticides, give a better, if not full, representation of the cannabis plant and meet the customers’ desire for clean products. Realizing extracts as the growth-driver they are will make us use better, fresher starting materials. Understanding the underlying science and learning about the extraction processes will allow us to fine-tune the process to the point that we target extract customized cannabis concentrates. Those, in turn, will not require additional multi-step purification processes, that destroys the basis of the entourage effect.

The cannabis industry needs to invest and educate. Better extracts are the result of knowledgeable, skilled people using precise instruments. Backroom extraction with a PVC pipe and a lighter should be horror stories of the past. And only when the patient knows how their medicine is made can they make educated choices. Through knowledge, patients will understand why quality has its price.

In short, over-processing to make clear oil violates both the plant’s complexity and consumers’ desires. Let us strive for pure extracts, not clear. Our customers deserve it.



Cannabinoid Extraction Techniques

Here’s how it works: Cannabis is dissolved in a liquid solvent, such as butane, which draws the cannabinoids and terpenes out of the plant. Then the solution is evaporated with heat under a vacuum to remove all the gas and leave a high purity cannabis concentrate behind. Butane is a popular solvent because it doesn’t extract harmful compounds like pesticides and is one of the cleanest extractions possible.

But not all solvents are created equally. That’s why it’s important to learn about the different classes of cannabis solvents, the potential risks, and what you can do to make sure your finished product is free of contamination.


While there are no legal guidelines targeting solvents in cannabis specifically, solvents are regulated in consumer products and drugs. These regulations are based on 3 classifications:

Class 1 Solvents – Should be avoided. This category includes solvents that are known or suspected human carcinogens and/or environmental hazards.

Class 2 Solvents – Exposure to be limited. This classification includes solvents that are cancer causative agents of irreversible toxicity or suspected to cause significant but reversible toxicity.

Class 3 Solvents – Low toxic potential. This group is often recommended for cannabis and CBD extraction from hemp because it poses no known health risks to humans.
The solvents below generally fall under one of the three classifications, which correspond to residual safety limits. When considering the solvent used to extract your oil, it’s important to understand its classification.


Benzene is a chemical that exists naturally from sources such as crude oil and coal and is also a component of certain solvents. Benzene is considered a carcinogen and is not deemed safe at any level in consumer products. Benzene is a highly effective solvent, but can be life threatening when ingested. If you decide to use CBD oil extracted with benzene then you must satisfy yourself that all benzene has been fully evaporated or purged from the final product.
Inhalation of benzene either in the production phase or in the final product through oils, liquids or vaping cartridges can lead to serious risks to brain and immune function. Short-term illnesses include drowsiness and dizziness. High-level or extended exposure to benzene can also lead to diseases such as anemia and leukemia.

CLASS 2 SOLVENTS: Chloroform, Methanol, Toluene, n-Butane
Unlike benzene, Class 2 solvents can remain present in products, as long as they don’t exceed the safety threshold. Residual solvent exposure limits are usually measured in parts per million (PPM) and can vary greatly from one chemical to the next. For cannabis, acceptable levels may also vary depending on whether you’re testing an inhalable product versus an edible, or topical oil. These variations are based upon how the solvent interacts with heat or other chemicals when creating the product.
Long term exposure to high levels of class 2 solvents like chloroform can lead to liver and kidney damage.  Methanol exposure can lead to diseases of the optical nerve like blindness. At high levels, methanol can also be fatal. Toluene presents a risk because it’s a precursor of benzene. Exposure can cause fatigue, light-headedness and confusion in low dosages. At high dosages, toluene can cause memory loss, seizures and coma.

Unlike the aforementioned solvents, N-Butane is Generally Regarded As Safe (GRAS). This form of butane has a low boiling point that combined with other chemical compounds like propane can help remove residual solvents. On its own, low levels of n-Butane are safe and create fewer greenhouse gases compared to other chemical compounds, however inhaled butane's in general can cause drowsiness and cardiac arrhythmia's.

Ethanol, n-Pentane, Acetone, Isopropanol
(includes unclassified solvents: i-Butane, i-pentane)
Class 3 and unclassified solvents are generally considered safe and acceptable in larger doses than their class 2 counterparts.
As a whole, the side effects of Class 3 solvents are irritation of eyes and nose or intensified intoxication if inhaled directly. If ingested, something like acetone can also cause neurological damage. Overall, the process in which class 3 solvents would be used to extract cannabinoids and terpenes does not produce the high levels of exposure that would be considered harmful to people. Therefore these types of solvents are considered the safest to use for Full Spectrum CBD extraction.
