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.
CBD plays a major role in the immune system modulation which basically means that it helps in auto-immune conditions such as rheumatoid arthritis. Rheumatoid arthritis is a chronic progressive disease which causes inflammation in joints, resulting in painful deformity, and at times immobility in the fingers, feet, wrists, and ankles. Because to it’s anti inflammatory effects, CBD oil provides relief of joint pain caused by rheumatoid arthritis, and can also decrease joint destruction. 

It’s thought that CBD might affect your health by attaching to receptors in the body’s endocannabinoid system—a complex biological system involved in maintaining certain aspects of your health. Emerging research shows that endocannabinoids may play a role in regulating such functions as memory, sleep, and mood, as well as metabolic processes like energy balance. In addition, CBD oil may play a role in improving a variety of health conditions.

There’s plenty of research out there confirming CBD offers relief from a number of health issues. But if you really want to know whether it can help you, there’s an easier way: ask someone that’s tried it. Genuine, real-life users are reporting how CBD has given them the best sleep in years, relieved their anxiety and significantly alleviated their joint and muscle pain. Other candid reviewers report how CBD topicals leave them feeling renewed and radiated.

The unflavored oil is derived from organic hemp seed oil. It is considered both vegan and gluten-free, and does not have any artificial sweeteners or preservatives. The oil contains 0.3% THC, meaning those who face the possibility of drug tests may want to avoid taking it, but this relatively small amount produces little, if any, psychoactive effect. The price per mg is $0.11, making the Spruce Lab Grade CBD Oil less expensive than average.

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.

Hemp goes back as one of the oldest crops in human history. Why is it so popular? For starters, it requires half the water (even less for some crops!)  of wheat and can be grown without pesticides. For health enthusiasts or anyone generally considerate of the environment, this is a great news. This crop can then be used for nutrition as a great fiber source! The whole seeds are healthy for complete proteins and omegas, concentrated antioxidants, vitamins, and other healthy nutrients. Outside of the United States, hemp is grown as an industrial crop on a large scale. In Europe, for example, we reviewed over 3,000 cultivars before selecting the right farm for us. 
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.
While there’s no reason you couldn’t use it as a supplement, it’s not labeled as such, so it may not be subject to the same purity testing as a bona fide hemp oil supplement. The bottle is brown amber glass with an eyedropper on top, as is customary for oils like this, but the packaging also includes a facial sponge to underscore the recommended cosmetic use of the hemp seed oil.

Since it started becoming popular roughly two years or so ago, the general consensus has always been that since CBD oil from top brands does not contain the psychoactive properties of THC, it is therefore legal. Unfortunately, its legality is much more nuanced because of conflicting federal laws and new court cases. What is clear is that in one of the most recent court decisions on the topic, Hemp Industries Assoc. v. DEA, which came out on April 30, 2018, the US Court of Appeals for the Ninth Circuit found that Section 7606 of the 2014 US Farm Bill (the “Farm Bill”) preempts the Controlled Substances Act (CSA), the federal law which designates marijuana as a Schedule I substance (along with heroin and cocaine) making it illegal to possess or use. This means that when there is conflict between the CSA and the Farm Bill, the Farm Bill wins out.

So. According to the Controlled Substance Act definition itself, certain parts of the cannabis plant are clearly illegal, while others fall into a grayer area. One of these – for the most part – is CBD extracted from the “legal” parts of the cannabis plant, and non-marijuana industrial hemp plants, which, as defined by Section 7606 of the Farm Bill are cannabis plants with less than 0.3 percent THC.


While medical marijuana is grown to be high in CBD for the treatment of specific ailments, the THC content can vary dramatically, sometimes getting as high as the CBD content. For an excellent example of the types of marijuana you may find in a licensed dispensary, see this Strain Book. It shows you the types of plants, the percentages of CBD and THC, and even the taste and effects of the stain.

Multiple sclerosis (MS). There is inconsistent evidence on the effectiveness of cannabidiol for symptoms of multiple sclerosis. Some early research suggests that using a cannabidiol spray under the tongue might improve pain and muscle tightness in people with MS. However, it does not appear to improve muscle spasms, tiredness, bladder control, the ability to move around, or well-being and quality of life.
CBD shows promise in the treatment of anxiety disorders, according to a report published in the journal Neurotherapeutics in 2015. Looking at results from experimental research, clinical trials, and epidemiological studies, the report’s authors found evidence that CBD may help treat generalized anxiety disorder, panic disorder, social anxiety disorder, obsessive-compulsive disorder, and post-traumatic stress disorder. However, the authors caution that human-based research on CBD and anxiety is fairly limited at this point.
Once absorbed in your body, CBD also lasts a long time; levels of CBD in your blood remain high for between 18 and 32 hours (12). In terms of how long it takes for CBD oil to start having a noticeable effect on symptoms, studies in rats suggest that dramatic effects are visible within 72 hours of starting to take CBD, so you should notice a difference pretty quickly if CBD is going to work for you.
Canine consumers of CBD oil are well catered for by Green Garden Gold, which offers dog-friendly drops and peanut butter-flavored treats among its innovative range.

February of 2017, a Hawaii government committee passed a bill to decriminalize industrial hemp, removed it from the state’s list of controlled substances and excludes growing, possession, processing and the sale of industrial hemp from civil and criminal penalties. No license is needed to grow and the crop is treated as other plants such as tomatoes, fruits, and other vegetables.
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.

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.


When their doctor switched them to a highly purified CBD-only oil, these symptoms immediately disappeared, and their epilepsy remained controlled. A takeaway from this study, and other research suggesting that up to one in five CBD oil products could be contaminated with detectable amounts of THC, is that side effects from over the counter CBD oil products might not actually be due to the chemical action of CBD.
