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.

Customer Service: It’s difficult to find contact information on Calm by Wellness’s website, and their email address is listed incorrectly in two places (we tried sending them an email but it was not delivered). We were, however, able to get a response through Facebook, and the company does offer free shipping and a generous 30-day return policy on all orders.
And now, onto the thorny issue of legality. The simple answer to the question is yes — if it is extracted from hemp. The 2014 Farm Bill established guidelines for growing hemp in the U.S. legally. This so-called “industrial hemp” refers to both hemp and hemp products which come from cannabis plants with less than 0.3 percent THC and are grown by a state-licensed farmer.
Many people are tempted to believe that products that contain CBD only are the best, thinking that using just CBD alone is a more effective treatment. While products that contain single-molecule CBD, meaning that you won’t find any other compounds, are already provided as medicines, they are not exactly more efficient than whole plant extract CBD oil, when it comes to therapeutic effects.
Historically, hemp could legally be grown and cultivated for academic research purposes only. However, the legality of hemp growth has changed in the past year. In April 2018, Sen. Mitch McConnell of Kentucky introduced the Hemp Farming Act of 2018, a piece of legislation that proposed legalizing all hemp products at the federal level. The act was incorporated in the 2018 United States Farm Bill, which passed in both the House and Senate in December 2018. Per the farm bill, industrial hemp will be descheduled as a federally controlled substance.
These are the best CBD oil extracts, hemp edibles, balms and e-liquids that are available to buy in the UK, clearly listed by total CBD content (see red circles above each product). We feature only products we've tried ourselves and know are top of the range, both in terms of purity and strength. You can be assured that you are receiving a CBD oil from ethical UK or European suppliers who use organic crops and supercritical CO2 extraction. CO2 extraction ensures you receive a full-spectrum product and benefit from the entourage effect. All of these products are legal (less than 0.2% THC content) and fully certified.
Research suggests that CBD has anti-inflammatory benefits when applied externally. (2)  The antioxidant properties of CBD may also protect your skin from the free radical damage that leads to pigmentation, wrinkles, and signs of aging. (3) Topical application may also be beneficial for some skin conditions, like pimples and dryness, and may provide localized relief from muscle soreness and joint pain.

Another reported side effect of CBD administration is an unpleasant dry sensation in the mouth. This effect seems to be caused by the involvement of the endocannabinoid system in the inhibition of saliva secretion. A study published by Argentinian researchers back in 2006 showed that cannabinoid receptors (type 1 and 2) are present in the submandibular glands which are responsible for producing saliva.

CBD hemp oil has a huge range of potential health benefits and uses, including reducing pain, soothing anxiety, fighting chronic diseases, improving mood, eliminating depression, preventing inflammatory arthritis, protecting the immune system, balancing the metabolism, aiding sleep disorders, and healing the skin, among others. CBD oil can also be used in many different ways and has a variety of applications for natural health.
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].

CBD works for everyone in different ways. Certain CBD products, particularly edibles, require longer to work based on metabolism and the natural digestive process, so you may just need to wait a little longer. You may also need to experiment with servings sizes to determine exactly what works best for you. Start low and slow. If you’ve waited a few hours and feel like the CBD isn’t having an effect, very slightly increase your serving size and wait again. This may take some trial and error, but part of the beauty of CBD is the way it allows you to customize your servings and determine exactly how much you need.

Unlike THC, the psychoactive compound which is responsible for giving you that high effect, CBD, is non-psychoactive and a proven aid for nausea, pain, and anxiety (plus, if extracted from industrial hemp, it’s legal). CBD is also known to be anti-inflammatory, analgesic, antispasmodic, cell-regenerative, and anti–cell proliferative for bad cells. This means that CBD is a potential therapy for a range of medical conditions.
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.
The added stevia herb extract sweetener, along with the real citrus fruit flavor, ensured it tasted great and I only needed about 15mg of CBD (three x 5mg sprays) for the effects I was looking for. It dissolves very quickly, so all you have to do is spray some beneath your tongue and swallow. If, for some reason, the citrus taste is too strong, you can spray it into water and drink it.
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.
A report from the American Academy of Pediatrics (AAP) published in the journal Pediatrics cautions pregnant women and nursing mothers to avoid marijuana use due to possible adverse developmental effects to their baby. In a study reviewed for the report, short-term exposure to CBD was found to increase the permeability of the placental barrier, potentially placing the fetus at risk from certain substances.
