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.
In fact, CBD is therapeutic in nature, and will work to manipulate bodily systems at the cellular level to return afflicted organ systems, tissue systems, and even chemical systems in the central nervous system back to a state of health and homeostasis. This is precisely why it has been capable of treating conditions such as depression and anxiety, to chronic physical ailments such as pain, inflammation, arthritis, and more.
CBD is well tolerated in humans with doses up to 600 mg not resulting in psychotic symptoms (15). In the few small placebo-controlled studies performed, no significant CNS effects were noted. Oral CBD undergoes extensive first-pass metabolism via CYP3A4, with a bioavailability of 6%. Following single doses in humans, the half-life of CBD when taken orally is about 1 to 2 days.1 In vitro studies have shown that CBD is a potent inhibitor of multiple CYP isozymes, including CYP 2C and CYP3A (16, 17). Whether these in vitro observations are relevant at plasma concentrations likely to be seen in patients is unclear. In addition, given its metabolism via CYP3A4, clinical trials of CBD in patients receiving enzyme-inducing AEDs, such as carbamazepine or phenytoin, will require detailed pharmacokinetic studies.

So when people began touting the benefits of CBD for pain, it was a big deal. A non-addictive substance that can ease pain without making you feel high or groggy? It’s easy to see why CBD has been making so many waves. In fact, cannabis plants have a long history as a pain reliever. Whether or not it’s true that Queen Victoria took CBD-rich cannabis to help with menstrual cramps, it is certainly true that her royal physician, Sir J. Russell Reynolds, listed cannabis as “one of the most valuable medicines we possess.” Victorian doctors aside, there are also ancient Assyrian and Ayurvedic manuscripts that recommend cannabis for pain.
The amount of milligrams of CBD you should take depends on your specific reason for taking CBD. If you are using CBD to treat chronic pain, you might take a much higher dose than someone who would be using CBD for general wellness reasons. Google search for your specific condition or reason for taking CBD to find the dose that is appropriate for you. You can take CBD in high qualities, so feel free to test out different dosages and see how your body reacts. A standard dose of CBD is 10 mg once a day, but this varies so widely because each individual is different so this can’t be taken as a recommendation for you.
Using rigorous review methodology, Gloss and Vickery conclude that based on the low quality of the reports available, there is insufficient data available to draw any conclusions regarding the efficacy and or long-term safety of CBD in treating epilepsy (11). From the data available, it does appear that daily doses of 200 to 300 mg were safe in this small group of patients for a short period of time (14).
If this is not sufficient for calming your symptoms, a gradual increase of another 25 mg per day, over the course of 3-4 weeks, is recommended. While there have been no reports of more serious side effects when this oil is taken in larger concentrations, it is best to slowly increase your dose to find a comfortable and effective level, given your individual characteristics and needs.
After months of visiting doctors and sitting through tests like a human lab rat, it was determined that there was a slight anomaly in the anatomy of my temporal lobe—the part of the brain that controls hearing, speech, and auditory comprehension—which explains why every time I have a seizure, I suddenly don’t understand the English language. Epilepsy can’t be cured, so the only course of action available for me was to take a medication every day for the rest of my life. My neurologist prescribed a few different anti-convulsant medications, but they all made me feel tired, depressed, slow, and unlike myself—until finally, I found one that was slightly better than the rest.
Gloss and Vickrey conducted a Cochrane systematic review of the use of CBD in the treatment of epilepsy (11). Their methodology included only those trials that were randomized and controlled and excluded case series, case reports, and expert opinion. They were able to identify only 4 randomized controlled studies reported in the literature, and they included a letter to the editor and an abstract. The total number of subjects enrolled in these studies was 48 (11–14). While only four studies and a letter to the editor were in the actual analysis, the authors included a complete reference listing of all articles reviewed for inclusion.

People who experience psychosis may produce too much or even too little cannabinoids (from overactive dopamine receptors). CBD is milder than our internal cannabinoids and helps to re-establish a balance of cannabinoids in the brain. CBD also helps lower inflammation, which is often increased in schizophrenia. THC, on the other hand, is stronger than our internal cannabinoids (anandamide and 2-AG), this way potentially triggering psychosis [46, 48].

Tinctures – Typically tinctures are small glass or plastic “dropper” bottles that have cannabidiol oil mixed with a preserving solution such as alcohol. Tinctures were very a very common way to ingest botanical oils prior to the industrial revolution and are experiencing a resurgence in popularity as more people are looking for natural remedies. Tinctures with droppers allow you to put a few drops in your tea, under your tongue, or to bake the oil directly into your food.

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.

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.
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.  
Green Label hemp oil has the lowest CBD content of our RSHO™ because the cannabinoids in the oil have not been decarboxylated, making Green Label oil higher in CBDa than our other oils, containing a total of 50 mg of CBD per serving. Our popular Blue Label RSHO™ registers in the middle of our pure hemp oil potencies, containing 85 mg of CBD per serving. Finally, our filtered Gold Label RSHO™ tops out with 120 mg of CBD per serving, the highest of any of our products.

Over the past few years, increasing public and political pressure has supported legalization of medical marijuana. One of the main thrusts in this effort has related to the treatment of refractory epilepsy—especially in children with Dravet syndrome—using cannabidiol (CBD). Despite initiatives in numerous states to at least legalize possession of CBD oil for treating epilepsy, little published evidence is available to prove or disprove the efficacy and safety of CBD in patients with epilepsy. This review highlights some of the basic science theory behind the use of CBD, summarizes published data on clinical use of CBD for epilepsy, and highlights issues related to the use of currently available CBD products.
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).
In addition to all the benefits we’ve already discussed, CBD has been proven to have antioxidant and neuroprotective effects. This means that it helps repair the damage from oxidative stress, which is believed to be a primary cause of diseases like Alzheimer’s, Parkinson’s, ALS — even heart disorders and some forms of cancer. This is a hugely beneficial effect of CBD.
To make matters more confusing, nine states (including California, Washington, and Colorado) let residents buy cannabis-based products with or without THC. Nearly two dozen other “medical marijuana states” allow the sale of cannabis, including capsules, tinctures, and other items containing CBD or THC, at licensed dispensaries to people whose doctors have certified that they have an approved condition (the list varies by state but includes chronic pain, PTSD, cancer, autism, Crohn’s disease, and multiple sclerosis). Sixteen more states legalized CBD for certain diseases.
CBD is well tolerated in humans with doses up to 600 mg not resulting in psychotic symptoms (15). In the few small placebo-controlled studies performed, no significant CNS effects were noted.

Cannabidiol is the major nonpsychoactive component of Cannabis sativa. Over the centuries, a number of medicinal preparations derived from C. sativa have been employed for a variety of disorders, including gout, rheumatism, malaria, pain, and fever. These preparations were widely employed as analgesics by Western medical practitioners in the 19th century (1). More recently, there is clinical evidence suggesting efficacy in HIV-associated neuropathic pain, as well as spasms associated with multiple sclerosis (1).
The cannabis plant contains a unique group of carbon compounds often referred to a phytocannabinoids. The most common ingredient is THC, which creates the euphoric high effect. Due to the THC element in the plant, marijuana is often associated with a stoner stigma of people only wanting to get high. But that is far from the truth. Cannabis also contains other medicinal compounds including cannabinol, cannabigerol, cannabidiol, and cannabichromene.
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.

Deciding to use CBD oil as a natural therapy is one thing – figuring out which brand to use, what strength/concentration to use, and how much CBD to actually take is another thing altogether. Plus, with all of the products out there to choose from and their confusing mL/mg labels, it can be a nightmare trying to determine which one is best for you, or which one you should be taking for your specific condition.

In one survey, parents of children who suffer from treatment-resistant epilepsy and use CBD were asked about the benefits. 19 parents were included, 84% of which said that CBD reduced the frequency of seizures. Two parents said that CBD completely resolved seizures. Parents also reported improved alertness, sleep, and mood. Some side effects were drowsiness and fatigue [54].
And we have a long way to go before we fully understand the relationship between CBD and pain regulation. But strong anecdotal evidence, combined with multiple lab tests and even some clinical trials, have established that CBD holds a lot of promise for pain relief. Or in science-speak, CBD “represents a novel class of therapeutic agents for the treatment of chronic pain.”

So, what is the best way to use CBD oil? CBD comes in a variety of forms, such as oil, tincture, oil for vaping, sublingual spray, edibles, and topical creams, so you can choose the method that is most suitable for your use. The main idea behind all the methods of using CBD is to make sure that this cannabinoid ends up in your system in an easy manner, producing the results you want. But when it comes to choosing the right method, it depends very much on the optimal dose in your case, the results you wish to achieve, and how long you want its effects to last. So, there isn’t a general rule when it comes to using CBD products.

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.
However, switching to CBD oil from a conventional medication is far from a random stab in the dark. In fact, there was a large scale (and very well-documented) survey carried out less than two years ago that looked at precisely what percentage of patients were able to “swap” their side effect-inducing meds for a 100% natural, cannabis-based therapy.
We have receptors for cannabinoids in the whole body, but the first type (CB1) are very dense in the pain pathways of the brain, spine, and nerves. The second type (CB2) are more important for the immune system but is also involved in inflammation. By gently acting on both pathways, our internal cannabinoids and CBD can balance both pain and inflammation [64].
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.
