There are various processes used to produce CBD isolate from industrial hemp extracts, such as supercritical carbon dioxide (CO2) or ethanol-based extractions. The same extraction methods can also be used as a starting point for the production of THC isolate as well, but typically with marijuana plants instead of industrial hemp. To create an isolate, a number of components are removed from the plant, including other cannabinoids, terpenes, and flavonoids, as well as fats, lipids, and other compounds. After that, the CBD compound is separated from the rest of the extraction through a series of chemical washing and separation processes.
For starters, true CBD isolates consist of nothing but pure CBD, so there’s no need to worry about THC possibly entering your system and showing up on a potential drug test. Although it’s highly unlikely, trace amounts of THC found in hemp-derived CBD oil can theoretically cause a positive drug screening result.
Apply the CBD powder directly under your tongue and hold it there for about 60 seconds. With this method, the CBD is absorbed by the mucous membranes and delivered directly to the bloodstream, bypassing the digestive system to provide more immediate and effective relief.
It’s incredibly easy to measure CBD isolate dosages, as there’s nothing else to account for aside from the pure CBD. With other CBD-based products, such as broad-spectrum and full-spectrum CBD oil, the cannabinoid is mixed with other cannabinoids, making it more difficult at times to quantify the exact amount of CBD that is being consumed.

Anyone who wants to try CBD oil or other products may get cold feet after hearing about the presence of THC in hemp-derived products. But CBD isolate provides a way to enjoy the benefits of this cannabinoid without other unwanted plant parts.

I put a bit of the powder under my tongue and found the flavor to be much more enjoyable—though still not one I attribute to the natural flavors of cannabis.
The Tangie Terpsolate had a soft quality to it, thanks to a healthy soaking of terpenes which made it easy to break off the right dose without turning into dust. Its sweet, citrus flavors were pleasant and exaggerated, but lacked the complex earthy qualities of native cannabis terpenes.
CBD isolate is a crystalline solid or powder that contains upwards of 99% pure CBD. Medical patients most often ingest it orally or mix it into food or drinks. You can also smoke or vaporize it like many other cannabis concentrates.
The flavorless isolate delivered calming, mellow effects while the terpene-infused isolate offered an invigorating cerebral jolt.
I ordered two CBD isolates from Dank Dabber, who is local to the Seattle-area and I was curious to see how quickly they’d arrive. Dank Dabber makes great dabbing accessories, so I figured their product would be geared towards consumers who want to dab, like myself.
This has left some users concerned not just with which form of extracted CBD is most effective or what the proper dosage for them may be, but also with which method of supplementation gives the user the most relief in the right amount of time. Some of the most common methods include applying it sublingually, topically, or taking it in capsules. Vaping cbd is regarded by many to be the most bio-available way to administer, and as such, this has led to an increase in the demand for CBD isolate. This form of CBD is different from full-spectrum CBD extract in that it only contains CBD and none of the other cannabinoids, terpenes, or healthy fatty acids that commonly result from the whole-plant extraction process.
However, CBD isolate does have something to offer CBD users that full-spectrum extracts does not. The fact that full-spectrum extracts invariably contain low levels of THC means that some users prefer to play it safe and stick to pure CBD by itself, out of fear of failing a drug test or experiencing a form of “high”, although both of these occurrences have been found to be fairly unlikely.
Ian Jones is a journalist based in Manchester, England. He specialises in technology and food, with a heavy focus on vaping, CBD and medicinal drugs. He began writing professionally over 15 years ago and is a regular contributor to New Scientist, Vice and the Daily Mirror. He is also the resident CBD expert at the respected vaping website Spinfuel. He began looking at CBD in detail after discovering that it cured his mother’s arthritis, and has since become a leading figure in the UK when it comes to educating people about the CBD extraction process and exploring its curative properties.
A study published by the Lautenberg Center for Immunology and Cancer Research, which aimed its focus on the effectiveness of CBD isolate compared to full-plant extract, supported this concept, stating in its summary that “in all of the tests, the isolated CBD was ineffective both before and after a certain dosage, while the effectiveness of the full-spectrum solution continued to increase as higher doses were administered. The results all indicate that CBD is only effective against swelling and pain at a certain dose, and that cannabis solutions containing a full range of cannabinoids will continue to provide corresponding effects as the dosage is increased.”
Whole-plant extracts typically contain a carefully measured amount of the cannabis plant’s most prominent cannabinoid, THC, although usually not in a large enough amount to have any psychological effects. In many countries, a certain percentage of THC is illegal, so it is vital to know the amount of this cannabinoid when manufacturing products that contain full-spectrum CBD. When present together, CBD and its cannabinoid colleagues, as well as terpenes, produce what is known as an entourage effect. The synergistic relationship between cannabinoids and terpenes has been shown to increase the healing properties of each.
