The human body also produces cannabinoids, known as endocannabinoids, in a bodily system known as the endocannabinoid system (or ECS). The ECS promotes homeostasis by regulating a wide range of functions, including motor skills, mood, appetite, and sleep. As we age, our ECS produces fewer endocannabinoids; they may also decrease due to physical injury or disease. Replenishing depleted endocannabinoids with phytocannabinoids like CBD can help restore balance to the body.

But because all these products are illegal according to the federal government, cannabis advocates are cautious. “By and large, the federal government is looking the other way,” says Paul Armentano, deputy director of the Washington, DC–based National Organization for the Reform of Marijuana Laws (NORML), but until federal laws are changed, “this administration or a future one could crack down on people who produce, manufacture, or use CBD, and the law would be on its side.”

You should only use CBD products if you are willing to accept at least some risk of testing positive on a drug test. Not everyone who uses hemp-derived CBD oil tests positive. But it does happen. The risk of testing positive is lower if you’re using a broad spectrum or isolate product. These products have non-detectable levels of THC based on manufacturer testing.

The CBD oil in everything that’s sold by Receptra Naturals is extracted from hemp from family-owned farms in Colorado. And the oil produced by the hemp plants – which are cultivated completely organically – is only taken from the flowering parts to ensure its purity and quality. Those of an environmentally conscious bent may therefore particularly appreciate the company’s offerings, which include CBD oil blends that aim either to boost users’ overall sense of health or, for people who are particularly physically active, to just give them a bit more pep in their steps. The most potent of these oils is, for the record, a 4,000 mg concentrate. But Receptra Naturals’ range also includes a topical cream, a skin-conditioning body butter and a CBD extract blend for pets that, the producer states, may help with anxiety, mobility and digestion in animals.


Hemp Bombs is based in Tampa, Florida, and in addition to focusing on the purity and therapeutic effectiveness of their products, are dedicated to establishing themselves as a top brand in the industry with a specific target audience. One of our personal favorite products of theirs is the flavored CBD vape liquids, which are some of the best-tasting CBD vape juices we’ve ever had.

Koi CBD probably should be higher up on this list given their popularity, but since they’re geared more towards vaping and CBD vape oils, and I have never really used them too much. People who do use them everyday though say that they’ve got the best flavors of any CBD vape oil on the market, and I can say personally that their CBD gummies and spearmint CBD oil work decently as well. I would recommend Koi CBD if you’re big into vaping and have yet to find a CBD vape oil that you like, and/or if you’re looking for a reputable brand that sells high quality oral CBD tinctures as well as edibles and vape products – might as well order everything in one place.


Additionally, PlusCBD oil is incredibly rigorous and transparent when it comes to testing their products and sharing the results. They perform thorough in-house testing to verify potency and screen for contaminants. PlusCBD Oil also validates its own in-house testing with independent third-party testing via DB Labs to ensure all products are free of pesticides, fungicides, residual solvents, heavy metals, and microbiological contamination.
CBD has proven neuroprotective effects and its anti-cancer properties are being investigated at several academic research centers in the United States and elsewhere. A 2010 brain cancer study by California scientists found that CBD “enhances the inhibitory effects of THC on human glioblastoma cell proliferation and survival.” This means that CBD makes THC even more potent as an anticancer substance. Also in 2010, German researchers reported that CBD stimulates neurogenesis, the growth of new brain cells, in adult mammals.
What exactly is cannabidiol (CBD) and more importantly, what does it do? Those questions and more are at the heart of this comprehensive guide to one of the most fascinating and important compounds of the cannabis plant. Cannabis plants are chemical powerhouses that produce more than 400 different compounds. Not all of those compounds are unique to marijuana, of course, and appear in many other species of plants. That’s why marijuana can smell like pine trees or taste like fresh lemons. But of those 400 compounds, more than 60 of them are totally specific to the plant genus Cannabis. Scientists call these special compounds “cannabinoids.” However, not all cannabinoids are created equal. One of them, cannabidiol, or CBD, holds the key to the wide variety of medicinal and therapeutic effects marijuana offers.
People taking other medications: When side effects are reported, it’s often by this group. CBD appears to have a similar effect to grapefruit on the liver’s ability to metabolize certain drugs, which can lead to adverse side effects. Generally, if a medication has a grapefruit warning, you should avoid taking CBD. Although, if you are on any medication you should talk to your doctor before starting CBD, to ensure you won’t expect any negative interactions.
The vast majority of CBD oils come in bottles measuring either 15 milliliters (mL), or 0.5 ounces; or 30 mL, or 1 ounce. However, CBD concentration is more important than bottle size. Concentration refers to the ratio of hemp oil solution (measured in mL) compared to the amount of CBD cannabinoid (measured in milligrams, or mg). A 15-mL bottle may contain 100 mg of CBD, 300 mg, 500 mg, or more. The higher the mg amount, the stronger the CBD oil will be. For this reason, the ‘mg’ measurement is also referred to as the oil’s strength; i.e., 400-mg oil might be called 400-strength oil.
Fab has rapidly become the leading “lifestyle” brand in the industry. They are very engaged with their customers in their online community, and they have the top customer loyalty program that we’ve seen. Their full spectrum CBD oil drops and topical cream are made from 100% organically grown Colorado hemp, producing a very high-quality product. And their zero THC gummies get high marks from customers for taste and effectiveness.

In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
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.

If you are discovering the benefits of CBD then our Pure CBD e-liquids may be the best place to start. Vaping is the recommended and one of the most effective method of consuming CBD as vaping facilitates absorption into the body. Our CBD vape liquid is produced for VSAVI in Europe in “Clean Room” laboratories. It is safe, natural, pure and free from both contaminates and THC.
Aside from maybe only PureKana, CW Hemp is probably the most popular CBD brand in the U.S. – at least in terms of the amount of product that they sell. And indeed they make some great, highly effective tinctures, but the only reason I don’t have them ranked higher is simply because I think they’re a bit overrated – and overpriced. If you’re into name brand reputation and will feel more comfortable buying from an established company like CW, by all means don’t be afraid to spend the money and try them out – they certainly don’t lack for quality. I just think there are other brands out there that offer better overall value for the amount of money that you’re spending.  
*[A couple things of note before I begin the reviews. In order to avoid redundancy and limit repeating myself dozens of times over, be advised that (unless otherwise noted), all of the companies listed below employ standard practices that are used by all of the best CBD oil companies, including things like: solventless CO2 extraction, 3rd party laboratory testing, legal THC limits below 0.3%, shipping to all 50 U.S. states, etc..]
Chronic Pain: The body’s ECS plays a role in alleviating and managing pain, so CBD oil can work as a supplement for individuals with medical conditions that cause chronic pain, such as arthritis and multiple sclerosis. CBD oil also increases levels of adenosine in the brain; adenosine is a neurotransmitter that aids cardiovascular function and eases painful inflammation.
Dispensaries: In states where marijuana is legal for recreational use, dispensaries are a common sight. They are much rarer in states with more restrictions. In states that permit the use of medical marijuana, hemp-based CBD oils do not normally require a prescription but marijuana-based oils do. Like brick-and-mortar locations, dispensaries offer more customer service. However, as noted, this may not be an option depending on the buyer’s state of residence. Also, CBD oil prices tend to be significantly higher at dispensaries.
Newcomers to CBD oil should leave Hemplucid’s website better informed than they were before visiting. That’s because the company offers a helpful and thorough guide to recommended dosages, depending on need; it also provides a handy breakdown of the methods by which users can consume CBD oil and explanations of the contents of Hemplucid’s products. And for those unsure as to whether CBD oil use is all above board, Hemplucid’s “due diligence” section ought to put minds at rest, since it relays exactly how the brand’s goods “exist within the language of the law” – with relevant court judgments included. Anyone subsequently convinced to consider trying the company’s wares for themselves can, moreover, choose from its extensive range. This includes lotions, softgels, gummies, a vape additive – and a water-soluble, full-spectrum oil that is able to easily be added to drinks.
CBD oil is prohibited for sale by terms of service on the major online marketplaces, including Amazon, eBay, and Groupon. Most of the products sold as CBD oil on those websites are hemp seed oil and don’t contain any CBD. We’ve also heard many reports of counterfeit and potentially dangerous products being sold as CBD oil on those websites. Your safest option is to always buy directly from the CBD company’s official website.

Transparency: Fab’s website features third-party lab results for most products. They only have a lab test for one of their tinctures though (which shows results for cannabinoid potency, as well as contaminants like pesticides). Customer service pointed out that the same CBD oil is used for all their products, but since potencies do vary, we appreciate companies that show potency testing for all products.

Kat’s Naturals not only takes the quality of its products seriously, but it also ensures that their contents are produced in a way that’s as environmentally friendly as possible. The essential oils in its best-selling Heal CBD Hemp Oil, for example, are harvested in a sustainable manner, while the hemp that goes into its range more generally is completely organically grown. And in a customer-friendly move, Kat’s Naturals provides CBD oil blends specifically tailored to users’ needs, whether they want to boost metabolism, get a good night’s rest or simply feel freer from muscle pain. Perhaps the most innovative Kat’s Naturals product, though, is its CBD-containing capsaicin cream. This topical owes its heat in part to a component commonly found within chili peppers, and the company’s website claims that it also helps give respite to neuropathy sufferers and those with Raynaud syndrome.

The CBDistillery has two main strengths. The first is its variety of options. The CBDistillery offers CBD oil tinctures in a wide range of concentrations from 17mg up to 88 mg of CBD per serving. But what really sets the company apart is that they offer both full-spectrum and THC-free CBD oil options. Most people gravitate towards full-spectrum CBD oil to take advantage of the entourage effect. But with THC-free CBD oil, you can enjoy the benefits and effects of CBD even if you’re subject to mandatory drug testing.
So let’s get something straight; Mary’s Nutritionals is the sister company of Mary’s Medicinals (actually they’re the same company), which is one of the cannabis industry’s most established names in cannabis CBD oil – that is to say, CBD oil that is extracted from marijuana and only legal in states with medical legalization (and for those with valid MMJ cards). Mary’s Nutritionals is the legal “hemp-based” version of Mary’s Medicinals; they extract their products industrial hemp like all other brands on the list, and thus are able to ship to all 50 U.S. states. Truth be told I don’t have a ton of experience with them because they’re so expensive, but believe me – their “Remedy” line of CBD oils are easily the best products on the market. That is, if you’re ready to splurge the cash on them. Also, they’re the only company we’re aware of that sells a legal CBD transdermal patch that you use like a nicotine patch. I’ve never actually tried it before, but I heard it works incredibly well.
There are very few known adverse side effects of CBD. According to this study, CBD is “a major non-psychotropic constituent of cannabis, has multiple pharmacological actions, including anxiolytic, antipsychotic, antiemetic, and anti-inflammatory properties. But if you are looking for a high from CBD, you will not get that because CBD has no psychoactive effects. Do speak with your physician if you are concerned about drug interactions.
This is the second time Moon Mother Hemp Company has placed among the top 10 brands on our ranking. The Colorado-based company, which was founded about a year ago, sets the bar very high for quality (including USDA-certified organic hemp) without charging the moon for its products. Their tinctures taste so good, you may be sad you don’t need more.  
What you gain from Full Spectrum CBD is called the “entourage effect.” Studies have suggested that CBD is most effective when it’s combined with other cannabinoids. Each cannabinoid has its own properties and confers its own benefits. Working together, a synergy is created that boosts the healing properties of CBD. Full spectrum CBD does, however, bring with it the sticky issue of THC. The government regulates concentration levels of THC at 0.3 percent, an amount which results in minimal psychoactivity.
Several weeks after a hysterectomy last spring, Bo Roth was suffering from exhaustion and pain that kept her on the couch much of the day. The 58-year-old Seattle speech coach didn’t want to take opioid pain-killers, but Tylenol wasn’t helping enough. Roth was intrigued when women in her online chat group enthused about a cannabis-derived oil called cannabidiol (CBD) that they said relieved pain without making them high. So Roth, who hadn’t smoked weed since college but lived in a state where cannabis was legal, walked into a dispensary and bought a CBD tincture.
Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.

Cannabidiol (CBD) is a naturally occurring compound found in the resinous flower of cannabis, a plant with a rich history as a medicine going back thousands of years. Today the therapeutic properties of CBD are being tested and confirmed by scientists and doctors around the world. A safe, non-addictive substance, CBD is one of more than a hundred “phytocannabinoids,” which are unique to cannabis and endow the plant with its robust therapeutic profile.
