This is good news for the best CBD oil companies because the Farm Bill allows for the legal cultivation of industrial hemp, under certain circumstances, which can be a source of CBD. But CBD can also come from non-industrial hemp, namely the marijuana plant that most are more familiar with. Therefore, whether or not CBD oil for pain is legal can be a question of which “version” of the cannabis plant it was sourced from. If it was sourced from industrial hemp, (which contains less than 0.3% THC by volume), and it was cultivated under the Farm Bill, then it is legal.

We’ve ranked every one of the high-strength CBD vape oils on this list according to a variety of attributes. We’ve graded them according to potency, quality, strength, flavor, shipping speed, customer service, and pricing; among other factors. Every one of the products on this list has been hand-selected by our editorial team. No matter which product you buy from this list, you can rest easy knowing that you’re buying one of the best high-concentration CBD oils on the planet today.

While animal experimental data clearly suggest a potential benefit, supportive clinical data are quite sparse. In a case-control study of 308 cases of new onset seizures, Brust and colleagues found that marijuana use was significantly less prevalent among men who had unprovoked seizures compared to case controls (9). This difference was not significant in women. The authors suggest a potential protective effect against seizures with marijuana use; however, this should be considered speculative.
Cannabidiol pharmacological effects are mediated through G protein coupled receptors, cannabinoid type I (CB1) and cannabinoid type II (CB2), which are highly expressed in the hippocampus and other parts of the central nervous system (2). When activated, CB1 receptors inhibit synaptic transmission through action on voltage-gated calcium and potassium channels, which are known to modulate epileptiform and seizure activity (3). CB2 receptors are primarily expressed in the immune system and have limited expression in the central nervous system. The effects of CBD are CB2 receptor independent (3).

Research on CBD and anxiety has generally looked at cannabis as a whole product, not as CBD as a standalone compound. Some studies suggest that it can help with anxiety: like this 2011 study that suggests CBDcan reduce social anxiety or this 2015 review that says CBD could be promising for many forms of anxiety. It’s also important to consider whether the CBD comes from the cannabis plant and therefore may include THC, a cannabinoid that for some, induces anxiety. Read our comprehensive article on CBD and anxiety, here.

However, like we just mentioned CBD oil for pain management that has been sourced from industrial hemp grown under the farm bill is in fact legal to buy and sell. The best CBD oil brands that we cover here on this site, claim to extract their concentrates from U.S.-based industrial hemp supplies, which if true, are 100% legal since they contain negligible amounts of THC.


There’s still a lot of unknown territory, but early evidence for CBD’s efficacy is more than enough to justify further large-scale clinical studies — some of which are already in the works. These studies also point to the variety of effective ways to take CBD. This is an important point to keep in mind if you find yourself shopping for CBD products and wondering if the best CBD for pain is a topical, a tincture, or a vape product.
Our bodies are thought to produce endocannabinoids by the billions every day. “We always thought the ‘runner’s high’ was due to the release of dopamine and endorphins. But now we know the euphoria is also from an endocannabinoid called anandamide,” its name derived from the Sanskrit word for bliss, says Joseph Maroon, MD, clinical professor and vice chairman of neurosurgery at the University of Pittsburgh Medical Center. We produce these natural chemicals all day, but they fade quickly because enzymes pop up to destroy them. That’s where CBD comes in: By blocking these enzymes, CBD allows the beneficial compounds to linger.
Although it is great that you have compiled a long list of the best CBD oils, so that we get some choice also as consumers, however, I rely believe in your well researched information that you share always, and so I feel the number 1. you shared, Purekana is going to make the choice for me. Ordering it tonight, and let’s see how my CBD journey goes from here. A bit nervous though!

Schizophrenia is a disorder that generally requires heavy antipsychotic drugs just to manage daily life. However, this systematic review notes that such drugs “provide limited cognitive benefits,” which is extremely rough given the side effects antipsychotic drugs can have. As discussed in the review, CBD may be a possible alternative to such heavy prescription drugs.
CBD is the major non-euphorigenic component of Cannabis sativa. Some research is beginning to show that CBD is different than other well-studied cannabinoids. All cannabinoids function as ligands, meaning they dock onto the binding site of a protein and have the ability to modulate a receptor’s behavior. CB1 receptors are widely distributed, but are particularly abundant in areas of the brain, including those concerned with movement, coordination, sensory perception, emotion, memory, cognition, autonomic and endocrine functions.
Pioneers of the CBD industry, 4 Corners Cannabis helped pave the way for companies that want to provide quality products and utilize best practices. They grow their own strain of hemp and make small batches of true full-spectrum CBD products. Their prices place them lower down on our ranking, but their highly satisfied customers are more than willing to pay for the 4 Corners quality.  
However, if it was sourced from actual marijuana (i.e. cannabis that contains more than 2% THC by volume), then it is technically illegal. Most of the best CBD oils for pain that you find in dispensaries in states like Colorado, California, and Washington (as well as other states where weed is legal) will have been extracted from marijuana plants — not industrial hemp plants. Unfortunately, this means that these products are not allowed to be sold online and shipped across state lines to “non-legal” states.

Dr. Cohen has found that chronic conditions including autoimmune diseases and pain syndromes can be helped with a 6-mg under-the-tongue tincture (the fastest delivery system) or a 25-mg capsule taken twice a day. Dosages for topical products like lotions are especially hard to determine—there’s no clarity on how much CBD gets into the system through the skin.
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.

Numerous studies have found results that confirm the ability of marijuana to help anxiety and stress. In 2013 an Israeli study demonstrated that treatment with cannabinoids helped to control emotional responses and prevent stress-related responses for those that had experienced a traumatic experience. In 2015 a group of researchers found that cannabis treatments were effective in reducing anxiety in those suffering from PTSD.


There are more than 80 cannabinoids found in cannabis plants, with THC being the primary one, followed by CBD. However, in the hemp plant, which is a different strain of the species Cannabis sativa, CBD is the main active ingredient, and THC is barely present, making its use and legality more widespread. The reason that CBD is such an effective form of support for human health is due to the body’s endogenous cannabinoid system. This regulatory structure of the body has millions of cannabinoid receptors in the brain and nervous system, which react not only to plant-derived cannabinoids (such as hemp and marijuana) but also to natural cannabinoids produced within our body. When hemp oil is used and processed by the body, it is effectively boosting the function of the endocannabinoid system, helping our body regulate itself in many different ways.

It is extremely effective in helping to treat chronic pain, support recovery from exercise-induced inflammation, swelling, management of normal, everyday stresses, and to help promote healthy sleep cycles.
CBD may be best known for its relaxing, calming effects. CBD reduces autonomic arousal, having the inverse effect of THC on the body. CBD’s anti-anxiety effect is why many in the cannabis community talk about how CBD relieves paranoia, although that is not scientifically proven yet. CBD is also known for its anti-nausea and pain relieving effects. It really depends on why your body’s specific needs and the quantity in which you take CBD.

In your internet travels, you may also come across products called “terpsolates.” The manufacturers of these products infuse CBD Isolate with terpenes (but not cannabinoids like THC). These terpenes may enhance the effectiveness of CBD — or maybe they just make it smell good. This may be a good place to point out that not all CBD products are created equal. The industry is still largely unregulated, and the quality and quantity of CBD in a given product will vary wildly. Third-party testing definitely helps to monitor companies’ claims, but it’s still up to you as the consumer to do your homework on the best CBD products.
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, DO, a cannabis doctor in Boulder, CO.

The endocannabinoid system is spread throughout your brain and body, but primarily throughout your central nervous system. The interaction between cannabinoids and receptors is what produces effects like the regulation of mood, pain, appetite, inflammation, and memory. Plant-based cannabinoids, found in cannabis plants, also interact with the receptors (whimsically named CB1 and CB2) in the endocannabinoid system, and each affects your body in different ways. CBD and its infamous cousin THC are the 2 most well-known cannabinoids.
Other targets for CBD include transient receptor potential (TRP) channels that are involved with the modulation of intracellular calcium (1, 6). Cannabinoids are highly lipophilic, allowing access to intracellular sites of action, resulting in increases in calcium in a variety of cell types including hippocampal neurons. CBD actions on calcium homeostasis may provide a basis for CBD neuroprotective properties.
Pharmacology published a study in 2016 looking at medical marijuana for migraines, specifically in relation to its effects on serotonin, with very positive results. You’ll notice that neither study looked at CBD in isolation from other cannabinoids (which is an issue with a lot of research on CBD and pain). Truthfully, the research on CBD alone just isn’t sufficient to make any pronouncements about its effects on headache pain.
CBD was also found to disrupt the consolidation of generalized fear memories when administered immediately after the acquisition of such fear memory. Interestingly, the timing of the administration of CBD was vital as the results demonstrated that delayed administration of the CBD dose did not have the same effective result that immediate administration did.

In fact, not only will CBD not make you high, it has been proven to counteract the psychoactivity of THC. This property makes CBD highly useful as a medical treatment for a wide range of conditions. In terms of the CBD products you can buy, the amount of THC present varies from none at all in a pure CBD Isolate to a minimal amount (less than 0.3%) in a Full-Spectrum CBD product.
Unfortunately due to the disappointing and down right inaccurate position of the federal government in classifying Cannabis as a schedule one drug, most research institutions risk federal funding if they conduct real research on Cannabis. This has dramatically limited the potential for real research by real scientists to be conducted. That research is critical to better understanding the multitude of therapeutic effects of the various chemical constituents found in Cannabis.

Unlike THC, which primarily binds to CB-1 receptors located in the brain, CBD works in the body by manipulating receptors throughout organ tissues, the immune system, the pain response system, the hormonal system, and other whole-body regulatory systems. Basically, since its receptors have been found to exist in virtually every cell and tissue type in the body, CBD is believed to work on every aspect of human health and behavior – from the subcellular level to the whole-body leve and beyond.


When administered alone, CBD is an effective anticonvulsant in maximal electrical shock (MES), magnesium-free, 4-aminopyridine, and audiogenic models (7, 8). Co-administration with AEDs leads to various effects; anticonvulsant effects of CBD are enhanced with phenytoin or phenobarbital but decreased with chlordiazepoxide, clonazepam, trimethadione, and ethosuximide. In a recent study using an acute pilocarpine model, although CBD administration reduced the number of animals displaying seizure activity, CBD did not appear to have any significant effect on the number of seizures per animal (7).

Side effects of CBD include nausea, fatigue and irritability. CBD can increase the level in your blood of the blood thinner coumadin, and it can raise levels of certain other medications in your blood by the exact same mechanism that grapefruit juice does. A significant safety concern with CBD is that it is primarily marketed and sold as a supplement, not a medication. Currently, the FDA does not regulate the safety and purity of dietary supplements. So you cannot know for sure that the product you buy has active ingredients at the dose listed on the label. In addition, the product may contain other (unknown) elements. We also don’t know the most effective therapeutic dose of CBD for any particular medical condition.
