Cannabidiol, a non-euphoriant phytocannabinoid common in certain strains, shares neuroprotective effects with THC, inhibits glutamate neurotoxicity, and displays antioxidant activity greater than ascorbic acid (vitamin C) or tocopherol (vitamin E) (Hampson et al 1998). While THC has no activity at vanilloid receptors, CBD, like AEA, is a TRPV1 agonist that inhibits fatty acid amidohydrolase (FAAH), AEA’s hydrolytic enzyme, and also weakly inhibits AEA reuptake (Bisogno et al 2001). These activities reinforce the conception of CBD as an endocannabinoid modulator, the first clinically available (Russo and Guy 2006). CBD additionally affects THC function by inhibiting first pass hepatic metabolism to the possibly more psychoactive 11-hydroxy-THC, prolonging its half-life, and reducing associated intoxication, panic, anxiety and tachycardia (Russo and Guy 2006). Additionally, CBD is able to inhibit tumor necrosis factor-alpha (TNF-α) in its own right in a rodent model of rheumatoid arthritis (Malfait et al 2000). At a time when great concern is accruing in relation to NSAIDs in relation to COX-1 inhibition (gastrointestinal ulcers and bleeding) and COX-2 inhibition (myocardial infarction and cerebrovascular accidents), CBD, like THC, inhibits neither enzyme at pharmacologically relevant doses (Stott et al 2005a). A new explanation of inflammatory and analgesic effects of CBD has recently come to light with the discovery that it is able to promote signaling of the adenosine receptor A2A by inhibiting the adenosine transporter (Carrier et al 2006).

Research suggests that CBD may exert some of its pharmacological action through its inhibition of fatty acid amide hydrolase (FAAH), which may in turn increase the levels of endocannabinoids, such as anandamide, produced by the body. It has also been speculated that some of the metabolites of CBD have pharmacological effects that contribute to the biological activity of CBD.
Industrial hemp contains, by weight, far less CBD than CBD-rich cultivars such as Harlequin or Sour Tsunami. This means that producing a single 10 mL dose of CBD would require the cultivation and extraction of far more hemp than it would from whole-plant marijuana; thus raising the risk of exposing users to more contaminants. Hemp is classified as a “bioaccumulator,” or a plant that naturally absorbs toxicants from the soil.
Brain receptors are not only sensitive to neurotransmitters produced naturally within the brain, like dopamine or serotonin, but also chemical messengers produced outside the body, such as plant cannabinoids like THC or CBD. So when you ingest an edible or inhale some vapor, you’re allowing compounds originally produced by a plant to enter your body, travel through your bloodstream, and enter your brain. Once they arrive, these plant-derived compounds can influence brain activity by interacting with receptors on neurons. But they don’t interact with all neurons, just the ones that have the appropriate receptors.
Cannabidiol is POSSIBLY SAFE when taken by mouth or sprayed under the tongue appropriately. Cannabidiol in doses of up to 300 mg daily have been taken by mouth safely for up to 6 months. Higher doses of 1200-1500 mg daily have been taken by mouth safely for up to 4 weeks. A prescription cannabidiol product (Epidiolex) is approved to be taken by mouth in doses of up to 10-20 mg/kg daily. Cannabidiol sprays that are applied under the tongue have been used in doses of 2.5 mg for up to 2 weeks.
The most commonly used form of CBD is CBD oil. Combining CBD extract with a carrier oil like coconut oil, it can be ingested or vaped, bringing a lot of variety. But because marijuana legalization is in such a murky situation with both federal and state laws to grapple with, CBD oil's legality can be hard to parse depending on where you are. Let's start with legality at the federal level.
Cannabis sales have been illegal since the 1970 Controlled Substances Act was passed, with the only exceptions being the products made from the "mature stalk" and "sterilized seed" of the hemp plant, which could still be sold since they contained little to no psychoactive components. Even today, federal law has not changed its stance on cannabis. On the state level, however, things have changed dramatically. As of this writing, there are 30 states that have legalized the sale of cannabis in some form, whether that be medicinally or recreationally. Because federal law continues to outlaw the production and sales of cannabis aside from the CBD oil and hemp seed oil from hemp plants, it is illegal for states that have legalized cannabis to sell products across state borders.
"Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism. This new found property makes cannabinoids useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia.
California’s legalization spurred Dr. Geoffrey Guy and Dr. Brian Whittle to found GW Pharmaceuticals, a company that would utilize clinical trials to unpack various cannabinoid formulations as potential therapies with the overriding focus of developing what would later be known as Sativex (Nabiximols). This oral mucosal spray was made up of CBD and THC in a 1:1 ratio and successfully combated neuropathic pain, spasticity, overactive bladder, and symptoms of multiple sclerosis.
Because of this classification, it's not easy for researchers to get their hands on the drug. "That's not to say you can't do it, but there are hoops you need to jump through that can be a pain, which may deter researchers from going into this space," Bonn-Miller said. "Relatively speaking, it's a small group of people in the U.S. that do research on cannabinoids in humans."
After using this for about six months, he’s thrilled that he is finally able to get a measure of restorative sleep (thanks to the THC); he also thinks it helps ease some of his pain, especially when used in conjunction with muscle relaxers. However, he’s even more impressed with the CBD: he’s convinced it has helped during his lengthy withdrawal from Klonopin. He also thinks it helps his other meds work faster and more effectively.
Although THC is best known for its mind-altering euphoria, it too has important medical benefits. There’s some overlap in what CBD and THC can treat, but THC is particularly effective in relieving nausea, appetite loss, insomnia, among other symptoms. Many patients find that a balance of CBD and THC offers the best symptom relief as the two work together synergistically.

To calculate the cost per milligram of CBD, simply divide the dollar amount of the product by the total milligrams of CBD in the bottle. So for instance, a product with 600 mg CBD in a 1 fluid-ounce bottle costing $80 is equal to about 13 cents per mg of CBD; a product with 100 mg of CBD in the same size bottle selling for $40 works out to 40 cents per mg of CBD. In this case, it pays to splurge on the $80 bottle.
Elixinol has a wide range of products, but their CBD Tincture does the trick. It’s the cream of the crop regarding CBD oils and that reflects in its price.

Elixinol has received numerous awards for their products and extraction process.

I've been suffering from anxiety for a while now and thought I'd try this... I drink tea regularly and decided to put it in my zen tea. The peppermint flavor in it compliments really well and I've noticed a decline in my anxiety. Its honestly such a nice soothing relief. I would recommend this to anyone who suffers from anxiety and wants a natural remedy.
I have severe neuropathy in both feet and legs. I just got the CBD oil and I am interested in learning if anyone out there has had any success with this. I know each case and pain levels are different. Just would like to see some positive remarks from people who suffer with it. I am not looking for a cure just need an update on someone who took and it helped. I already know there is no cure. I need help with the pain. Thank you.
