No, pure CBD oil does not contain THC, and therefore would not affect a drug test testing for THC. Most widely-used drug tests are comprised of an immunoassay that has antibodies for detecting metabolites that are produced from the oxidation of THC. These drug tests do not have cross-reactivity to CBD. Therefore, they give negative results when only pure CBD is used. One study of CBD oil users revealed that unlike THC, CBD does not show up on drug tests (source.)
Later in 2014, researchers reported on preliminary results of a study involving children with treatment-resistant epilepsies in an expanded access “compassionate use program.” Patients received a purified 98 percent oil-based CBD extract called Epidiolex, which is made by GW Pharmaceuticals. After 3 months of treatment, 39 percent of the 23 patients had more than a 50 percent reduction in seizures, with a 32 percent median reduction. These preliminary results support the animal studies and survey reports that CBD may be a promising treatment for treatment-resistant epilepsy and it is generally well-tolerated in doses up to 25 milligrams per kilogram of body weight.

A 2007 study with the pharmaceutical 1:1 CBD:THC spray showed good results in helping patients with chronic pain sleep better. REM sleep behavior disorder (RBD) is characterized by the loss of complete muscle relaxation during REM sleep, associated with nightmares and physical activity during dreaming. Four patients in a case series treated with CBD in 2014 had prompt and substantial reduction in the frequency of RBD-related events without side effects. 
Cannabidiol is insoluble in water but soluble in organic solvents such as pentane. At room temperature, it is a colorless crystalline solid. In strongly basic media and the presence of air, it is oxidized to a quinone. Under acidic conditions it cyclizes to THC, which also occurs during pyrolysis (smoking). The synthesis of cannabidiol has been accomplished by several research groups.
According to the National Institute of Mental Health, approximately 15 million adults in the United States have social phobia and about 6.8 million have a generalized anxiety disorder. Traditional treatment usually involves counseling and medications. Treatment with CBD may be better than anti-depressants because it acts quickly and does not cause side effects or withdrawal symptoms.
I wonder if you’ve every heard of someone who starts using the CBD oil and their anxiety and depression gets worse. This is what I’m experiencing now. I took Prozac for several years, but have been off of it for over 3 years. I was looking for a good alternative (the side effects of Prozac were unbearable). Maybe it’s a dosage issue. I have been using the drops, about 12 drops two times a day. This particular brand is 200 mg per dose (dose is 30-40 drops). I know you can’t give advice, but I just wondered if you have heard of this happening.
2.) What a fantastic study with such positive results! In a nation (United States) where 1 out of 3 people suffer from diabetes, WE NEED MORE STUDIES! This was an animal study, but great results for CBD hemp oil to be a potential health benefit for humans. Here’s what the study stated, “We now report that CBD potentially relievement significantly reduces the incidence of diabetes in NOD mice from an incidence of 86% in non-potentially relieveed control mice to an incidence of 30% in CBD-potentially relieveed mice.” View Source
CBD (Cannabidiol) is a potent, non-psychoactive cannabinoid found in hemp oil. It is typically extracted from industrial hemp plants that are naturally high in CBD and other phytochemicals. It is the most prevalent of over 80 different cannabinoids found in natural hemp. It is commonly used for its therapeutic properties. Cannabidiol is responsible for a wide-range of positive health benefits through its interaction with the body's own endocannabinoid system.
“The brain has these receptors that respond to endocannabinoids, which are neurotransmitters that are naturally produced in the body and brain,” says Jerald Simmons, a neurologist at Houston’s Comprehensive Sleep Medicine Associates. “Some of the cannabinoids in the marijuana plant are very similar to the endocannabinoids in the brain, and they act on the same receptors.”
In the meantime, some physicians are forging ahead — and cashing in. Joe Cohen is a doctor at Holos Health, a medical marijuana clinic in Boulder. I asked him what CBD is good for, and he read me a long list of conditions: pain, inflammation, nausea, vomiting, intestinal cramping, anxiety, psychosis, muscle spasms, hyperactive immune systems, nervous system degeneration, elevated blood sugar and more. He also claimed that CBD has anti-cancer properties and can regenerate brain cells and reduce the brain’s levels of amyloid beta — a kind of protein that’s been linked to Alzheimer’s disease. I asked for references, noting that most of these weren’t listed in the Academies report or a similar review published in the Journal of the American Medical Association. “I think you just have to Google search it,” he said. It’s true that a preliminary study found hints that cannabinoids might reduce beta amyloid proteins in human brain cells, but the study was done in cells grown in a lab, not in people. As for cancer, the FDA sent warning letters last year to four companies that were selling products that claimed to “prevent, diagnose, treat or cure” cancer.
As per the blog says, I’ve been relieved from the chronic pain by CBD Oil. About half a year ago I was suffering from chronic pain in my head and any of the medicines were not working on me. I’ve changed many doctors but none of them was able to do the treatment of that. One day, one of my friends suggested me to try CBD oil for the chronic pain. I did some research about CBD online and ended up purchasing the CBD Oil from All Natural Way. I start taking CBD Oil daily and after some days my pain got vanished. I really liked the CBD products and happy to have it. Now I and my family take CBD in our daily life to stay healthy. I recommend taking CBD Oil for everyone.
Hi Ben. What are your thoughts on the differences, if any, between CBD extracted from hemp (legal to buy for anyone in the US) and CBD extracted from medical cannabis? My instinct is that once extracted, they should be identical because we’re talking about a specific molecule (similar to how ascorbic acid extracted from an orange or bell pepper or made in a lab are identical). However, I had some CBD oil from a major retail website that did not do much for my insomnia, even at high doses. Then I tried some CBD oil from my medical marijuana doc that he claimed was pure CBD (meaning no THC, but I am not sure if there are other terpenes) and of higher quality because it was extracted from medical grade cannabis. I was totally skeptical, but ending up feeling it big time – very calming, almost like being high, but without the random racing thoughts that THC gives me. I am wondering if it’s worth it to shell out for my doc’s product (it is super expensive), or if I should just try another version of hemp-based CBD, such as the one you recommend.
CBD Oil with THC – This type of oil isn’t legal in all states, and has a different effect than pure CBD oil. Many people take marijuana for the effects of THC, as it helps them to battle different medical conditions. They believe that the two combined provide an enhanced experience that exceeds the beneficial properties of taking one over the other (i.e. just taking THC or CBD by themselves). It is important to note that THC can counter the benefits of CBD, and therefore correct dosing is essential.
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.

At present, we have the following classification of cannabinoids: endocannabinoids (produced naturally in the body, mainly from fatty acid precursors), phytocannabinoids (compounds that have a plant origin, with the cannabis plant being the best-studied source of phytocannabinoids though not the only one), and artificial cannabinoids (created while studying THC, to garner the benefits of marijuana without the recreational component).
