CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.

“The need for enhanced bioavailability of the CBD phytonutrient is paramount”, adds Moriarity, “but tricky to accomplish without synthetic chemicals.” Most CBD products do not offer any bioavailability optimization, so 90 percent of the CBD is lost to first-pass effect, a phenomenon of drug metabolism whereby the concentration of a drug is greatly reduced before it reaches systemic circulation.
To get almonds from an almond tree, you can just shake the tree. To get juice from an orange, you can simply squeeze the fruit. But getting CBD oil from hemp is a much more complicated process. The cheapest and easiest ways to extract CBD oil from hemp commonly involve harsh solvents that can leave chemical residue in the CBD oil. The best, and most reliable extraction method, uses carbon dioxide (CO2) under high pressure and extremely low temperatures to pull out as much CBD as possible without introducing contaminants. Once the CO2 is no longer under intense pressure, it simply evaporates, leaving virtually no trace of extraction on the CBD oil.
There are numerous CBD tincture products to choose from, with different flavors and CBD strengths, and all of them are very easy to use. Tinctures trump all other types of CBD products in terms of serving size precision, as you can easily increase or decrease your serving size by the drop (tinctures typically come with a precise dropper or a spray).
Does Amazon sell CBD oil? Yes. You can also find cannabis oil for sale online via Amazon, though this tends to change from month to month over the last 4 years now.  There used to be a time where you could purchase many of the brands profiled in our merchant stores such as Charlotte's Web on Amazon, but Amazon has since permanently removed merchants who had used the term "CBD" in their labeling. Consequently, to find CBD online via Amazon, you will be first searching for "hemp oil" products, and then filtering out the hempseed oil from the CBD rich hemp extracts. Terms such as "full spectrum" and "whole plant" are commonly used to distinguish these hemp products on Amazon in 2018. 
Everybody has different medical needs, because of this Medix CBD hemp oil tinctures are available in different dosages ranging from 100mg – 4,500mg per bottle. The reason for such a large difference in CBD concentrations between the lowest strength bottle and the highest strength bottle is because we offer a vast and wide selection of CBD hemp oil tinctures to meet the needs of people with different medical goals.

Conversely, to preserve most of the plant’s trichromes – these are the cannabinoids, terpenes, and flavonoids – look for Supercritical (or subcritical) CO2 extraction. This method uses carbon dioxide under high pressure and extremely low temperatures to isolate, preserve, and maintain the purity of the medicinal oil. While this method is more expensive and involves complex equipment and expertise, it ensures quality.

One of the main appeals of CBD oil (apart from its obvious health benefits) is that it will not get you high. The famous “buzz” associated with cannabis is solely down to THC, and this is so often where less knowledgeable people get confused. CBD oil on its own should not provide any high to the user, and this is why it is such a popular choice for the treatment of so many conditions.

But there’s a big difference between the two. Hemp seed oil has been pressed from hemp seed, and it’s great for a lot of things – it’s good for you, tastes great, and can be used in soap, paint – even as biodiesel fuel. However, hemp seed oil does not contain any concentration of cannabinoids at all, including CBD. So by all means, stock up at your local natural food store. Just don’t expect to reap the benefits of a true CBD oil when you cook with hemp seed oil.
The reason for the low THC content in hemp is that most THC is formed in resin glands on the buds and flowers of the female cannabis plant. Industrial hemp is not cultivated to produce buds, and therefore lacks the primary component that forms the marijuana high. Furthermore, industrial hemp has higher concentrations of a chemical called Cannabidiol (CBD) that has a negative effect on THC and lessens its psychoactive effects when smoked in conjunction.

All the products we carry use the same hemp extract discussed above.  So, it doesn’t really matter which product type you get, you’re still getting the same extract.  And, that’s all that really matters.  So, the decision as to which product type to get comes down mainly to preference.  Do you prefer the specific measuring ability of the drops?  Do you prefer the convenience of a capsule?  These are merely preferences for the most part.
For example, using CBD vape oil requires a vaporizer, something you may be unfamiliar with, and for a beginner it can be intimidating. But vaping is only one option, and if you’re new to the world of CBD, a tincture is your best bet—it’s portable, discreet, and easy to use. And with only a few drops or sprays on your tongue, it’s super easy to keep track of your daily serving size.
With no regulations when it comes to the distribution of CBD hemp-based products, you can never be sure what you are purchasing.

Multiple rounds of testing through different independent labs also represents an investment by the seller in creating transparency around their wares. With so many CBD oil purveyors in today’s market, it’s worth shopping around for one that makes sure customers know exactly what’s in every bottle. And if you’re looking to try a CBD product, you can get 50% off of your first order from Diamond CBD by using the code LEAFLY50.

Hemp also contains fatty acids which have been known to be great for the body. Unlike its marijuana counterpart, hemp contains high quantities of CBD and low volumes of THC for which its grown. While marijuana is illegal to consume in many states, hemp is slowly becoming more popular and more states are legalizing the uses of hemp oil for its citizens.

Because the extraction used to make our CBD oil yields a full spectrum extract, our hemp extracts contain over 80 different phyto-cannabinoids, including CBD, CBC, CBG, CBG-A, CBC-A, CBN and many others. In addition to the cannabinoids naturally present in our industrial hemp extracts, there are also many other types of natural molecules such as amino acids, carbohydrates, vitamins (including B1, B2, B6, D), fatty acids (including omega 3 & 6), trace minerals (including iron, zinc, calcium, magnesium, potassium), beta-carotene, chlorophyll, flavonoids, ketones, nitrogenous compounds, alkanes, glycosides, pigments, water, and terpenes. The most common terpenes in our hemp cannabis oil are Myrcene, Beta-caryophyllene, Terpinolene, Linalool, alpha-Pinene, beta-Pinene, Nerolidol og Phytol, trans-alpha-Bergamotene, Limonene/ beta-Phellandrene (Co-elution), and alpha-Humulene.

In the U.S., we live in a culture where more is often perceived as being better.  And it’s easy, without even thinking about it, to apply that approach to CBD dosing. But when it comes to CBD, more is not necessarily better. In fact, for many, less CBD is more effective. One way to determine your optimal dosage is to start with a small amount of CBD for a couple weeks and then slowly increase your dosage, carefully taking note of symptoms, until you’re seeing the results you want.
Watch Out For: Companies that do not have test results or refuse to give them to customers. Also be wary of companies who only test one batch of finished product and then assume that all future batches will be the same – big mistake. Hemp is a product of nature and thus, no two batches will ever be identical – even in the most regulated environment. The company must provide you test results for the actual product you intend to purchase as well as the plant material used to make it – otherwise you are jeopardizing your safety and the medical efficacy of the product.
There’s some confusion between medical marijuana CBDs that contain THC and the THC-Free Hemp CBDs within states. CBD Daily uses CBD derived from hemp that is THC-free – which is drug-free, and can be sold everywhere legally. However, there are a couple states that have certain restrictions on CBD sales that prevent us from selling there. Please see our map to the right to see if we are able to ship to your state.
Look for brands who source their cannabinoids from organic-certified, hemp-grown farms in pristine regions of Europe. “The German regulatory system is strict and enforced, providing confidence in the superiority of their harvest, processes, and extraction quality,” adds Moriarity. Organic hemp grown in Europe must also adhere to EU’s strict organic standards, which are stricter than in the U.S. and highly audited. Also, look for ingredients that are certified organic and wildcrafted.
I would recommend always going with a full spectrum oil. Some people say to use nothing but pure 100% CBD, but if you do a little research you’ll see that most doctors will say that the full-spectrum products with terpenes etc are much more potent and effective. I would only use the CBD isolate if I was concerned about an upcoming drug test (full spectrum has trace amounts of THC in it)
Receptra Naturals CBD products are derived from proprietary CBD rich hemp, grown on family owned and operated farms in Colorado using 100% organic farming practices on select organic soils without the use of pesticides or fungicides.  I got to know the folks at Receptra while dealing with Charlotte's Web Botanicals and continued to stay in contact when they left CW to form Receptra.

Tinctures are ideal for CBD novices, as they’re not always as strong as other CBD product types. If you know how much CBD you require and you’re after a higher concentration, a regular CBD tincture is unlikely to deliver the goods. However, this is beginning to change as companies experiment with higher concentrations. In the meantime, consider a vape oil, paste, or concentrate to enjoy a stronger CBD experience.
You can purchase CBD and hemp oil in specialty retail stores – over the counter (i.e. nutrition stores and smoke shops). Physical stores offer buyers the ability to see the products before they purchase as well as gives them the chance to actively engage with store associates by asking questions and learning about other products that they might be interested in. When you are looking to choose a reputable and high-quality CBD retailer, it is also important to inquire about the product’s third-party test results. This way, you will be assured that you are getting a high-quality and safe product as reputable companies will invest in such tests to gain the trust of their customers.
Finally, in general, we almost always recommend full spectrum tinctures over supplements made from isolates (extracts of CBD alone). Full-spectrum or whole plant tinctures take advantage of the ‘entourage effect’ that comes from combining all the naturally occurring chemicals found in the hemp plant. Isolates are great for cooking with CBD or consumers that are especially sensitive to the taste of hemp extract, but some research suggests they may be less effective for certain uses than full spectrum extracts. All but two of the brands below are made from full spectrum hemp, and the exceptions are clearly noted.
While researchers are calling for more robust studies on the role of CBD on mood disorders, there is promising research that points to CBD’s role as an anxiolytic – which means it has anti-anxiety effects. Another study showed CBD to have antidepressant effects comparable to those of the prescription antidepressant Imipramine. We noted above that CBD increases levels of glutamate and serotonin – and it’s these same neurotransmitters that play a crucial role in mood regulation.
While THC affects your brain’s endocannabinoid receptors (resulting in the high), CBD does not attach directly to the receptors. Instead, it influences your body into using its own natural supply of cannabinoids more effectively. That is to say, it can inhibit or activate compounds in the ECS, which in turn can impact the amount of pain you feel or limit inflammation in the brain and nervous system.

Pesticides, mold, and other contaminants are obviously substances you don’t want to be mainlining into your body, but properly dosed CBD is also crucial. That’s because your body’s response to CBD dosage is bell-curved. Too little and you won’t feel anything; too much and it’ll dampen the impact with reported side effects like lethargy and diarrhea (not chill). Given the lack of research into dosage and the variety of ailments CBD is used for, most people have to find their own “Goldilocks Zone.”


As of now, there are only 9 states (and Washington, D.C.) that permit the use of marijuana on a recreational level. This means that, depending on where you live, it may or may not be possible to just walk into a dispensary and ask for a bottle of fine quality CBD oil. Also, some of those 9 states (even though they are recreationally legal for weed) may actually require you to obtain a medical marijuana card or a physician’s recommendation for CBD oil. If this is the case, though, it’s really no biggy as getting an online recommendation is incredibly easy nowadays, and can usually be done in minutes..
We gave the highest points to companies that use a CBD distillate for their tinctures. The process of distillation creates an extract that is pure on a molecular level. There are people who think distillate is too pure, and that a full spectrum decarb produces a more effective tincture. But in light of the inconclusive evidence, we prefer a distillate. The process allows for a high degree of control as to the finished product. It’s also odorless and tasteless, so those tinctures tend to taste better.

Called a week later, and was told to email the manager, and was informed he always responds within 1-2 days. Emailed him, and it’s been 2 weeks, since. I called GreenRoads, asked my question, and got an immediate, literate response (multiple hemp sources), as well as a discussion on what differences might or might not occur, and how to check lab sheets for comparison. Switched over to GreenRoads, which seems otherwise comparable in its manufacturing methodology to Elixinol.

CBD oil is a refined oil rich in the cannabinoid molecule cannabidiol, more commonly known as CBD. Unlike it’s more infamous cousin, THC, CBD is not psychoactive, meaning it doesn’t cause the traditional high associated with cannabis. And while CBD oil can be sourced from any cannabis plant, it is commonly derived from agricultural hemp—cannabis plants bred to express less than 0.3% THC and thus have no intoxicating potential.

So, back to the difference between how effective hemp extract is compared to marijuana extract.  It is the subtle mixture of how much CBD and how much THC and how much of the other cannabinoids that can change the effectiveness for people.  For most of us, we won’t notice much difference in the subtle variations, other than the extract from marijuana will make you high, while the extract from hemp won’t.  However, there is a very small percentage of people whose bodies can tell the difference.  Some people find that they get better results when using an extract high in THC.  And, some people find that they get better results when using an extract that is low in THC.  This just comes down to these people’s bodies; and again, the percentage of these type of people is very low.
