Transparent test results that are easily accessible also help customers ensure they’re looking at data that’s relevant to the product they’re actually ordering. Past performance is no guarantee of future results, and a good grade for one batch of product doesn’t always translate to the next round. That’s why responsible testers don’t stop at one good result, but continually update customers with the latest data available on their products.
This may seem like a repeat of an earlier question, but while that question related to concentration of CBD in the product, this is simply a question of how much you’re getting in total. Most bottles are labeled in a similar way – “1,000mg CBD Oil” or “1,000mg Hemp Extract” – which generally means the entire bottle contains a total of 1,000mg of CBD.

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.
Once companies have these test results, sharing them with customers is not just a best practice—it should be a priority. After all, you shouldn’t have to guess what’s in the bottle or wait to read results until a product arrives in your mailbox. That, says Diamond CBD, is why their team makes test results for CBD oils and tinctures available online, right next to the product description.
Of course, that data has to be displayed someplace that’s easy for consumers to find. Trustworthy CBD retailers are transparent with their ingredients and test results not just online, but on their products as well. Clear and accurate labeling is key, as it ensures customers never have to wonder what’s in the bottle of CBD oil they ordered—they can always find out at a glance.

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.
But, and there’s always a “but” when it comes to weed in America, unless you’re buying cannabis CBD in a state where weed is recreationally legal or have a medical card in a legalized state, you’re shopping in the unregulated market that is industrial hemp CBD. (Full disclosure: I've worked with restaurants to launch hemp-CBD drinks and am the co-founder of Nice Paper, a site about cannabis.)

At a molecular level, CBD (short for cannabidiol) is CBD, regardless of which plant it comes from.  The only difference comes from the full extract that is taken from the plants.  Here’s what we mean:  Once the plants are harvested, the lab removes the nutrients, including CBD, from the plants in the form of a gooey extract.  This extract includes the CBD, but also so much more and this gooey extract is what goes into all the CBD products*.  There are actually many cannabinoids other than just cannabidiol (CBD).  Some are CBC, CBG, CBN and even THC.  THC is the compound found in marijuana that causes the “high” or psychotropic or euphoric effect.  As most of us know, marijuana naturally has a fairly high level of this compound.  Hemp naturally has a very low level, so low that no one reports any sort of high when using the extract from hemp.

I’ve been using this oil for about 9 months and love it. One dropper before bed and I sleep like a baby. I am a lucid dreamer and nothing I tried would get me through the night. At least nothing that wouldn’t make me super groggy the next day. This oil has changed my life. I’m more even-keeled and stress doesn’t get to me as it used to. If you were thinking about trying CBD for yourself, kids or dog, this is the stuff.
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.”
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.
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.

Are they open about third party tests and willing to share the results? When in doubt, ask for multiple lab tests including from the farm and a third-party lab. They’ll list out contaminants, solvents, and the percentage of cannabinoids. According to White, “brands should be happy to share their results as they’ve invested in those tests. If they aren’t transparent, it’s suspect.” Brands like RITUAL, Care by Design, Humbodlt Apothecary and Kinslips have all gone through rigorous testing standards as they are cannabis derived. Since you can’t travel across state lines with cannabis CBD, industrial hemp CBD brands that have well-sourced farms and openly share tests include Lily CBD, Rosebud, Honey Pot Supply, and Soul Addict.
GMP stands for Good Manufacturing Practices, and it covers the practices required to ensure products are produced according to industry standards. The agencies that control the authorization and licensing of the manufacture and sale of these products provide guidelines, and the manufacturer must adhere to these guidelines to make sure their products remain consistent and of high quality from batch to batch.

CBD testing shouldn’t just tell you what’s in a CBD oil, which is usually CBD along with a carrier oil like grapeseed oil and maybe some other essential oils for flavor. It should also let you know what’s not in the package. Thorough testing can confirm that the oil you’re buying is not only real CBD, but that it’s free of contaminants like pesticides and synthetic CBD substitutes.

In fact, numerous studies have looked at the relationship between CBD and pain, and the results are promising. Researchers have looked at various kinds of pain – from joint pain to cancer pain. One finding is that CBD increases levels of glutamate and serotonin – both neurotransmitters that play a role in pain regulation. And CBD’s anti-inflammatory properties help by tackling the root cause of much chronic pain.
Are you looking to buy CBD-rich oil? Finding the right CBD oil can be a daunting task, especially if you are a newbie. There are many ways of acquiring your Cannabinoid (CBD) oil. You can purchase the product online, from brick and mortar store, co-ops, dispensaries, and natural herbalists. CBD oil products can be made from extracts of either hemp plants or Marijuana Plants. Depending on your preferred mode of ingestion, the hemp-extracted oil is available in a range of applications including tinctures, topicals, vaporizers, vape pens, transdermal patches and as infused edibles.
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.
All this talk about THC lands us nicely in the whole “Full Spectrum vs. Pure Isolate” debate. Once you begin shopping for CBD products, you’ll notice a lot of jargon that gets thrown around without much explanation. Now that we’ve introduced THC into the conversation, we can talk about the difference between, and relative benefits of, Full Spectrum CBD and CBD Isolate (and the lesser-known contender: Broad Spectrum).
CBD oil is similar to other products in that it is capable of being “watered down.” Some companies will try to eke out a higher profit margin by fooling their customers into thinking they’re getting more for less. It is important to pay attention to the concentration level of the CBD oil you’re buying in order to ensure you’re getting what you’re paying for. Although concentrations of CBD can vary quite a bit across the broad range of CBD products, a quality product will start off having somewhere between 250mg to 1,000mg per fluid ounce. This matters because if you were to purchase a 4 ounce bottle that contained 250mg of CBD, your concentration would be a mere 62.5 mg of CBD per ounce – hardly enough to reap the full benefits of CBD. It’s always important to look at the concentration level of the CBD you’re buying.
