In your internet travels, you may also come across products called “terpsolates.” The manufacturers of these products infuse CBD Isolate with terpenes (but not cannabinoids like THC). These terpenes may enhance the effectiveness of CBD — or maybe they just make it smell good. This may be a good place to point out that not all CBD products are created equal. The industry is still largely unregulated, and the quality and quantity of CBD in a given product will vary wildly. Third-party testing definitely helps to monitor companies’ claims, but it’s still up to you as the consumer to do your homework on the best CBD products.
There’s a growing consensus that cannabis is a highly effective treatment for many kinds of neuropathic pain. A 2015 study published in Neurotherapeutics states, “Clinical studies largely affirm that neuropathic pain patients derive benefits from cannabinoid treatment.”   But much of the human-based research (like this study) on CBD and nerve pain has centered around the efficacy of the FDA-approved medication Sativex, which includes both THC and CBD. Research on the best CBD for pain isolated from THC is still limited when it comes to neuropathic pain. There are exceptions, though:
A number of difficulties exist in evaluating published data on CBD or marijuana use for epilepsy. The extremely limited published studies were small, poorly described, and not well designed. Contributing to the difficulty of interpreting published studies, CBD products are not produced under the guidance of good manufacturing practices (GMP) and are not subject to regulations governing labeling, purity, and reliability. In other words, currently, there is no guarantee of consistency between products, or even differing lots produced by the same manufacturer. Without independent testing (e.g. USP certification) of CBD products for content and purity, as well as bioavailability testing of specific products, uncertainty surrounds the use of available CBD products in routine clinical settings.

Other targets for CBD include transient receptor potential (TRP) channels that are involved with the modulation of intracellular calcium (1, 6). Cannabinoids are highly lipophilic, allowing access to intracellular sites of action, resulting in increases in calcium in a variety of cell types including hippocampal neurons. CBD actions on calcium homeostasis may provide a basis for CBD neuroprotective properties.
I recently was a guest at a medical marijuana educational event that highlighted the work of researcher Michael Backes. During his presentation he made a statement about CBD that I have never heard anywhere else that CBD is “regulating” (my word) the effects of THC. I asked the Nurse Practitioner at the event, Ivy Lou Hibbitt of Certicann.com, what he meant by that and she said it was her understanding of Michael’s comment that he takes CBD to reduce the psychoactive effects of THC. Has this property of CBD, that it can lessen psychoactive effects, ever been researched elsewhere?

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.
We’ve linked to the best, most reputable source for each one of these products (most frequently the manufacturer’s site). While you may want to shop around (and we encourage it!), we recommend that you buy from one of our preferred sites. That way you’ll know that you’re getting an authentic product at a reasonable price, from a company that actually stands behind their product.
CBD works by attaching itself to specific receptors of the body’s own endocannabinoid system. The human body is known to produce cannabinoids of its own, which affect the cannabinoid receptors CB1 and CB2. The CB1 receptors are generally found in the brain, and deal with pain, mood and emotions, movement, appetite, among others. THC acts upon the CB1 receptors. Meanwhile, CB2 receptors are more commonly found throughout the immune system, affecting inflammation and thus pain. CBD is thought to act upon these receptors, by influencing the body to produce its own cannabinoids in order to rebalance itself.

Another field in which CBD is creating a buzz is in the area of mood disorders like anxiety and depression. Both conditions have been treated with a variety of medications, courtesy of Big Pharma, that have had varying levels of success. Again, the long list of side effects can be off-putting to someone who just wants to get through the day without the sweaty tension of anxiety or the gray haze of depression.
According to the largest study to date, researchers reported that after treating 162 patients with an extract of 99% cannabidiol (CBD), for a 12 week period. the intervention reduced motor seizures at a rate similar to existing drugs ( a median of 36.5 percent) and 2% of patients became completely seizure free. Other studies have shown that it can act as an anticonvulsant.

But scientists have found that CBD doesn’t bind well with endocannabinoid receptors. Instead, CBD influences the system indirectly. This creates many benefits, which is why you’ll hear of CBD as a treatment for so many different medical conditions. And, unlike THC, it won’t make you high. When it comes to pain, we know that CBD has multiple functions. First, it influences neurotransmitters and receptors. One receptor known to be involved with pain and inflammation is called TRPV1 — also known as a vanilloid receptor. CBD binds to the TRPV1 receptor, influencing the way you perceive pain. CBD can also affect the production of neurotransmitters like serotonin and glutamate, which are related to pain sensation.

Ranging from irritating to debilitating, joint pain can be tricky to treat. If your pain is mild, ibuprofen or acetaminophen might be adequate. But the worse it gets, the more likely you are to be prescribed antidepressants, muscle relaxants, or even opioids. Because of the side effects associated with these prescription medications, there has been quite a bit of research on CBD and joint pain — with promising results. Here are a few studies that point to CBD’s potential:
Unlike other CBD oils, PureKana really does excel in CBD oil extractions due to their unique CO2 extraction process which provides a near 99% pure CBD oil. PureKana Natural CBD Oil is an unflavored, dietary and nutritional supplement for increased health and vitality. It is extremely effective in helping to treat chronic pain, support recovery from exercise-induced inflammation, swelling, management of normal, everyday stresses, and to help promote healthy sleep cycles.
CBD Vape Oil is very popular and can be used with a suitable vaporizer. Since this oil is generally viscous, it needs a device that can work with it. Therefore, it cannot be used with all vaporizers. Make sure you have a suitable vaporizer before using a CBD vape oil. CBD Vape oils have different concentrations and flavors. Adding terpenes also contributes to the effect.
Is CBD Legal? Marijuana-derived CBD products are illegal on the federal level, but are legal under some state laws. Hemp-derived CBD products (with less than 0.3 percent THC) are legal on the federal level, but are still illegal under some state laws. Check your state's laws and those of anywhere you travel. Keep in mind that nonprescription CBD products are not FDA-approved, and may be inaccurately labeled.

“Buying from a reputable manufacturer is crucial, because it matters how the plant is cultivated and processed,” Dr. Maroon says. One clue that a company is cutting corners: too low a cost. Good CBD is pricey—a bottle of high-quality capsules is sold in Cohen’s office for $140. But for many, it’s worth the money. Roth spent $60 on her tiny bottle. But when her energy returned the day she started taking CBD, she decided that was a small price to pay.

Tinctures: Tinctures are another popular way to use CBD, likely because you can easily gauge exactly how much cannabidiol you are ingesting, like CBD oil. A tincture is usually extracted with alcohol or another solvent. With a tincture, you use a dropper and place the drops in the mouth. Sometimes, manufacturers will use carrier oils, natural flavors or fatty oils in their tinctures.
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.
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].
Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.
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.
Bacon had said that I might need to try two full droppers worth of the oil to really feel its benefits. I knew that I had an incredibly busy and stressful day ahead of me—I needed to fit in a five mile run before work, had lots to do at the office, was scheduled for a busy event in the middle of the day, and had a 2-hour meditation class later that night which would require a lot of mental clarity. Tentatively, I squirted two droppers of CBD oil into my bulletproof coffee and sipped away.

Of course, there is a different side to the story also. It is true that the studies concluded so far have their limitations, and there is no saying what effects supplementation with CBD for more than 6 months could have. However, they suggest cannabidiol has the potential for treating some mental disorders, like anxiety and depression, seizure disorders like epilepsy, insomnia, and chronic pain.
This is why Amanda Oliver, 31, a career consultant in Charleston, SC, pops a CBD gummy bear each night before bed. “I used to lie there tossing and turning as my mind raced from work projects to whether I had set the home alarm,” Oliver says. One piece of candy with 15 milligrams (mg) of CBD is enough to shut off her brain and facilitate sleep. She also swears by the CBD oil she takes at the height of her period, which she says quells her debilitating cramps.

Studies have demonstrated that CBD has a low affinity for the CB1 receptors, but even at low concentrations, CBD decreases G-protein activity (3). CB1 receptors are expressed on many glutamatergic synapses that have been implicated in seizure threshold modulation. CBD may act at CB1 receptors to inhibit glutamate release (4). Studies have shown changes in the expression of CB1 receptors during epileptogenesis and after recurrent seizures (5). CB1 receptor expression is upregulated at GABAergic synapses and shown to be downregulated at glutamatergic synapses in epilepsy, contributing to lowering seizure thresholds.
Read the label to find out the total milligrams of CBD in the entire bottle/product and how many milligrams are in one standard dose. CBD products vary in potency, with some containing more total CBD than others. Most products will have on the label exactly how much CBD is in one dropper or drop, so you’ll be able to tell exactly how much is in there.
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.
While animal experimental data clearly suggest a potential benefit, supportive clinical data are quite sparse. In a case-control study of 308 cases of new onset seizures, Brust and colleagues found that marijuana use was significantly less prevalent among men who had unprovoked seizures compared to case controls (9). This difference was not significant in women. The authors suggest a potential protective effect against seizures with marijuana use; however, this should be considered speculative.

The reason so many people are interested in cannabis products that don’t make them high, proponents say, is that CBD helps with everything from pain and nausea to rheumatoid arthritis, cancer, Crohn’s disease, and dementia. CBD is anti-inflammatory, anti-anxiety, antibacterial, immunosuppressive, and more, says Joseph Cohen, DO, a cannabis doctor in Boulder, CO.
