The human body has an endocannabinoid system — a natural system that maintains homeostasis or balance, in the body. The endocannabinoid system has CB1 and CB2 receptors. These are found throughout the body. CB1 receptors are generally located in the central and peripheral nervous system and CB2 receptors are generally found in the brain, immune system, and gastrointestinal system. CBD binds to these receptors creating changes and effects in the body

There has been a fair amount of confusion surrounding the legality of CBD oil. But while the vast majority of cannabinoids are controlled substances under the Misuse of Drugs Act, rest assured that CBD oil is legal across the UK for medicinal purposes, provided it has been derived from an industrial hemp strain that is EU-approved. These strains contain very little to no THC (the psychoactive cannabinoid).

Now, as far as migraines cured I am using it also to help with my nerve pain from my spine and waiting to see if it helps my asthma. I have gone from 12 Gabapentins a day to 4-6. I’m hoping it worx for asthma. I have started taking it twice a day for the last 3 days and being in cold rainy damp weather with all the flowers and trees in bloom on top of my allergies I am hoping this CBD helps asthma to.


CBD hemp oil has a number of uses and comes in many forms including capsules, tinctures, sublingual supplements, liquid oil, oil as a paste, sprays, salves, creams and in edible forms, such as candies or sweets. You can also inhale CBD oil from vapor-releasing pens, similar to the technology for e-cigarettes. This variety also provides a lot of controlled flexibility in terms of concentration, making CBD hemp oil useful and desirable for people of all ages, economic means, and personal needs.


If you’re wondering what the function of the prefrontal cortex is, let us tell you. The prefrontal cortex is responsible for decision-making, attention, and other executive tasks, including motor skills. That means that when you consume THC, any of the above areas can be affected. For example, anecdotal evidence suggests that when people are “high,” they experience euphoria, time lapses, the decline in motor skills and mostly hunger.
Under federal law, cannabis (from which both CBD and marijuana are derived) is illegal everywhere, although the laws against it aren’t generally enforced in states that have legalized marijuana. Some manufacturers claim that CBD culled from legally imported industrial hemp, which has little to no THC, is fine to ship across the U.S., but many experts disagree, noting that because hemp comes from the same species as marijuana, cannabis sativa, all CBD falls under the DEA’s Schedule 1 designation. “This creative interpretation of the law runs afoul of reality,” says the Brookings Institution, a Washington, DC, think tank.
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.
‘The media has no doubt helped drive this popularity,’ says Dr Sarah Brewer, medical director at Healthspan. ‘However, the main drive is because people who take it experience the benefits very quickly, and “word of mouth” is a powerful thing. CBD oil also has such a wide range of benefits, reducing anxiety, promoting relaxation, ensuring a good night’s sleep, reducing pain perception and improving general feelings of wellbeing. It therefore appeals to a wide range of people.’

CBD affects the endocannabinoid system, which has cannabinoid receptors throughout the human body. That’s one of the major reasons why CBD’s therapeutic properties include pain relief. The cannabinoid receptors are connected to the human nervous system.  CBD affects some of them (not CB1 and CB2 which are activated by THC) and a  neural connection is triggered in the brain.

CBD is a chemical found in marijuana. CBD doesn't contain tetrahydrocannabinol (THC), the psychoactive ingredient found in marijuana that produces a high. The usual CBD formulation is oil, but CBD is also sold as an extract, a vaporized liquid and an oil-based capsule. Food, drinks and beauty products are among the many CBD-infused products available online.


Sub-lingual CBD drops have helped me enormously with sleeping and with radiation damage pain. I have a cancer that spread from the pelvic area to my sacrum and sciatic nerve and whilst the chemo and radiotherapy saved my life I have been taking MST (morphine derivative) for nerve pain ever since. My tumours are presently all quiet and last March I decided I wanted to stop taking the pain relief drugs, fearing dementia. CBD oil was recommended by my son who has arthritis and, for me, it really works. It’s so good to read an article that isn’t put out by a CBD sales site – I wish it could be properly prescribed and regulated (I’m in the UK) in order to have confidence with purity and dosage.

There’s no definite amount that’s appropriate for everyone, but the ratio of CBD to THC will indicate how psychoactive the product is and if it’s legal in your state. The more CBD compared with THC, the less of a high, and vice versa. “Managing psychoactivity is key to successful cannabis therapy,” says Lee. “Amounts should be made clear on the label and lab-certified so people know what’s helping them and what’s not.”
As the CBD oil market continues to grow, more and more products are being sold online or in your local health food stores. You can find many types of CBD and each one is used in a different way. The most common forms of CBD available include the following. (Of course, you should always consult your healthcare professional prior to using CBD and read and follow all label directions.)
Pain is a sign that something is not right in your body, and you need to identify its root cause to find the best relief and treatment. When something happens to your body, such as an injury or illness, your nerves send messages to your brain to protect you. As a protective warning sign, pain develops. It is basically a complex interaction between your brain, nerves, and spinal cord. Your pain may be physical or emotional, or even both (2).
The most efficient way to deliver CBD into the body is through inhalation. That’s because more of the product, and thus more of the active components of CBD are distributed in the bloodstream. However, you should be aware that they pass through the human system in a few hours. Note of reference, CBD is very different from THC, because CBD does not act as a psychoactive substance and doesn’t produce “a high.”
