You need a series of chambers for CO2 extraction. Their role is to control pressure and temperature. The pressure and temperature in the chambers force the CO2 cannabinoid solution to react with one another and then separate. As the cannabinoids separate, the chambers collect them separately. The extractor can then choose which cannabinoids to put into their product or products.
Before we directly compare the both, let’s break down what each is. Full spectrum CBD oil comes with all the cannabinoids present in hemp. If you see full spectrum hemp CBD oil for sale, it’ll include many cannabis compounds such as Cannabicycol (CBL), Tetrahydrocannabivarin (THCV), Cannabinol (CBN), Cannabichromevarinic Acid (CBCVA) and more. It also contains a very small amount of THC, (.3%, as is legally allowed).
There's also the question of CBD's legality – something that's a lot grayer than the black-and-white picture most companies paint. The U.S. Drug Enforcement Administration considers CBD, like all cannabinoids, a schedule 1 drug. That means it's just as illegal as heroin and ecstasy. Meanwhile, hemp – a variety of the cannabis plant regulated by the U.S. Department of Agriculture – is legal , so long as its THC content is negligibly low. But because the agriculture department doesn't test for CBD – only THC – in hemp, more companies are getting away with selling products they say contain CBD, says Sara Jane Ward, an assistant professor of pharmacology at the Temple University Lewis Katz School of Medicine who's been studying CBD in rodent models for more than 10 years. Needless to say, the legality of CBD is "very confusing and very gray," she says.
The same terms could be applied to what's actually in CBD products. While some do contain CBD, others (often marketed as "CBD-rich hemp oil") may have barely any, Asquith says. And depending on state laws, they can include varying levels of THC too – a combination shown to have some benefits, but also drawbacks, of course, if you're not looking for a high. "People will play all these games with the numbers because the consumers aren't really educated in this space yet and it's easy to get taken advantage of," he says. "It's the milligrams of the actual CBD molecule that matter."
CBD hemp oil is the product derived from the hemp plant, which is high in CBD (cannabidiol) and low in THC (tetrahydrocannabinol). This oil has received a large amount of attention in recent years, due to the growing wave of marijuana legislation and debate in many countries, including the United States. While cannabis and smoking marijuana (which often has a high level of the psychotropic compound THC) is still illegal in many places, as more is being learned about CBD, and its potential effects on health, it is becoming more and more accepted as a legal and safe remedy for a wide variety of health conditions. Since it has a minimal amount of the psychotropic compound THC, use of this oil does not result in a traditional “high”, so its effects are generally considered therapeutic, not mind-altering.
The reason so many people are interested in cannabis products that don’t make them high, proponents say, is that CBD helps with everything from pain and nausea to rheumatoid arthritis, cancer, Crohn’s disease, and dementia. CBD is anti-inflammatory, anti-anxiety, antibacterial, immunosuppressive, and more, says Joseph Cohen, D.O., a cannabis doctor in Boulder, CO.
Another major reason why CBD oil has been positively received in some parts of the medical community is its apparent effect on cancer and tumor growth.A study done by the researchers of the Institute of Toxicology and Pharmacology, University of Rostock, Germany recommends the use of CBD oil (even direct injection into tumors) to eliminate or reduce the size of the tumors. The antioxidants in CBD hemp oil also provide anti-mutagenic properties and lower users’ risk of cancer.
Healthy folks vaguely looking to add a little spring in their step (via better sleep, reducing anxiety, or easing muscle soreness) drizzle a little oil into their smoothie or latte. They might also spot-treat with a dab of oil in problematic areas. In the past several years, published papers have suggested that the compound can help with a spectrum of medical conditions, including anxiety, Alzheimer’s disease, addiction, arthritis, inflammatory bowel disease, fractures, migraines, psoriasis, and pain. In an animal study, purified extracts of CBD and THC appeared to slow the growth of a type of brain tumor.
Although CBD oils aren’t regulated by the FDA, purchasing products stateside from one of the nine states where recreational and medical cannabis use is legal will likely result in a higher-quality product than buying one made with hemp-derived CBD oil imported from abroad, says Martin Lee, director of Project CBD, a nonprofit that promotes medical research into CBD.
When looking at isolate, it is important to verify the purity. While many are in the 99.9+% range with no identifiable amounts of THC, there are lower purity ones (such as 99.5% or lower) that may still have trace amounts that show up on the labs. This small amount is typically negligible, and is nowhere near the amount usually found in full spectrum products. But it’s still something to be aware of for those seeking the purest they can find.
There are a number of possible side effects to using CBD oil, such as fatigue, dry mouth, lightheadedness, hypotension, and impaired motor functions. However, when used in moderate amounts, most people do not experience these side effects, and none of them are known for being fatal or particularly dangerous. More than 20,000 studies have been done in the past 15 years on cannabis, hemp, and cannabinoids, and the results have been overwhelmingly supportive of the therapeutic potential and viability of CBD oil. That being said, some people should be cautious before using this powerful oil.
Yes: CBD extracts can’t always be trusted. A 2017 JAMA paper reported that almost 70 percent of all CBD products sold online do not contain the amount of CBD stated on the label. Of the 84 products bought from 31 different companies, 42 percent contained a higher concentration of CBD oil than the label claimed, and 26 percent of the products contained less than the label claimed. The remainder of products contained the labeled amount—give or take 10 percent.
