In addition, some cannabinoids interact synergistically, producing unique effects that are not found when using them individually. For example, CBD inhibits THC’s psychotropic effects when the two are taken together. However, CBD does this (and produces many other effects) without directly interacting with the cannabinoid receptors. At first, scientists thought there was a third type of CB receptor just for Cannabidiol, but the answer was far more interesting and revealing.

Food and beverage products containing CBD were introduced in the United States in 2017.[dubious – discuss][47] Hemp seed ingredients which do not naturally contain THC or CBD (but which may be contaminated with trace amounts on the outside during harvesting) were declared by the FDA as GRAS in December 2018. CBD itself has not been declared GRAS, and under U.S. federal law is illegal to sell as a food, dietary supplement, or animal feed.[13] State laws vary considerably as non-medical cannabis and derived products have been legalized in some jurisdictions in the 2010s.
Thank you for your questions. Marijuana and hemp are two extremely different strains of the same cannabis sativa plant that have been bred over thousands of years to have entirely different purposes. (Hemp is not the male version of the marijuana plant.) They both contain CBD. Hemp only contains CBD whereas marijuana contains CBD and perhaps a hundred or so other chemicals with a variety of functions, such as THC, the molecule that makes people “high”. Any medicine can have different effects on different people. For example, Benadryl makes some people sleepy yet can make others wide-awake. So, it is not inconsistent for a particular medicine to cause a symptom in one person and to help alleviate it in another. So while many people experience relaxation with CBD, so people do experience the “paradoxical” effect of irritability.

Early preclinical findings also suggest that CBD may have therapeutic value as a treatment of substance use disorders. CBD reduced the rewarding effects of morphinexxxviii and reduced cue-induced heroin seekingxxxix in animal models. A few small clinical trials have examined CBD and/or nabiximols (THC/CBD) for the treatment of substance use disorders; however, the available data are not sufficient to draw conclusions. NIDA is supporting multiple ongoing clinical trials in this area.

Cannabidiol (CBD) is a naturally occurring compound found in the resinous flower of cannabis, a plant with a rich history as a medicine going back thousands of years. Today the therapeutic properties of CBD are being tested and confirmed by scientists and doctors around the world. A safe, non-addictive substance, CBD is one of more than a hundred “phytocannabinoids,” which are unique to cannabis and endow the plant with its robust therapeutic profile.

The NIH recognizes the need for additional research on the therapeutic effects of CBD and other cannabinoids, and supports ongoing efforts to reduce barriers to research in this area. NIH is currently supporting a number of studies on the therapeutic effects as well as the health risks of cannabinoids. These include studies of the therapeutic value of CBD for:


However, when cannabinoids are taken externally, it’s difficult to distinguish between the clinically desirable effects and the therapeutically undesirable effects of various phytocannabinoids. This is because cannabinoid receptors send a variety of signals that often interconnect to coordinate the body’s functions, so it’s hard to tell them apart.
If you haven’t been bombarded with CBD marketing or raves about it from friends, get ready. This extract—which comes from either marijuana or its industrial cousin, hemp—is popping up everywhere. There are CBD capsules, tinctures, and liquids for vaping plus CBD-infused lotions, beauty products, snacks, coffee, and even vaginal suppositories. Already some 1,000 brands of CBD products are available in stores—and online in states that don’t have lenient cannabis laws. This is a tiny fraction of what’s to come: The CBD market is poised to exceed $22 billion by 2022, per the Chicago-based research firm Brightfield Group.
Hemp oil volume is the least important of these, instead, it is important to consider the CBD Volume and Concentration as the most important factors. These provide information on how potent the dosage of CBD is within the product. It is usually recommended to start out with approximately one to three milligrams of CBD on a daily basis; thus do not buy a product that will deliver a dose that is too powerful for a beginner.
There has actually been a substantial amount of experiments done on cannabidiol that has proved its potential healing powers. Dr. Sean McAllister, a scientist from the Pacific Medical Center in San Francisco, made an astounding discovery about CBD. McAllister has been studying cannabinoid compounds for 10 years now in search of new therapeutic interventions for various cancers. He discovered that cannabidiol is a potent inhibitor of cancer cell proliferation, metastasis, and tumor growth.

CBD has proven neuroprotective effects and its anti-cancer properties are being investigated at several academic research centers in the United States and elsewhere. A 2010 brain cancer study by California scientists found that CBD “enhances the inhibitory effects of THC on human glioblastoma cell proliferation and survival.” This means that CBD makes THC even more potent as an anticancer substance. Also in 2010, German researchers reported that CBD stimulates neurogenesis, the growth of new brain cells, in adult mammals.
Unfortunately due to the disappointing and down right inaccurate position of the federal government in classifying Cannabis as a schedule one drug, most research institutions risk federal funding if they conduct real research on Cannabis. This has dramatically limited the potential for real research by real scientists to be conducted. That research is critical to better understanding the multitude of therapeutic effects of the various chemical constituents found in Cannabis.
Serving size can vary based on the product you choose and the CBD concentrations in that product, as well as your own metabolism. Edibles generally have longer lasting effects, but they also take longer to process as they have to go through your entire digestive system, which also breaks down some of that CBD. Edibles such as gummies or capsules are a foolproof way to ensure accurate and consistent serving sizes. CBD that is smoked or vaped acts faster and has less breakdown while also lasting less time overall.
There has been little high-quality research into the use of cannabidiol for epilepsy. The limited available evidence primarily focuses on refractory epilepsy in children.[15] While the results of using medical-grade cannabidiol in combination with conventional medication shows some promise, they did not lead to seizures being eliminated, and were associated with some minor adverse effects.[15]
There have been multiple clinical trials demonstrating the efficacy of nabiximols on central and peripheral neuropathic pain, rheumatoid arthritis, and cancer pain.xxiii In addition, nabiximols is currently approved in Canada for the treatment of central neuropathic pain in MS and cancer pain unresponsive to opioid therapy. However, the current evidence suggests that the analgesia is mediated by THC and it is unclear whether CBD contributes to the therapeutic effects.xxiv THC alone has been shown to reduce pain;xxv,xxvi we are unaware of clinical studies that have explored the efficacy of CBD alone on pain. However, the anti-inflammatory properties of CBD (discussed above) could be predicted to play a role in the analgesic effects of nabiximols. Recent research has also suggested that cannabinoids and opioids have different mechanisms for reducing pain and that their effects may be additive, which suggests that combination therapies may be developed that may have reduced risks compared to current opioid therapies. However, this work is very preliminary.xxvii
Some manufacturers ship CBD products nationally, an illegal action which the FDA did not enforce in 2018, with CBD remaining the subject of an FDA investigational new drug evaluation, and is not considered legal as a dietary supplement or food ingredient as of December 2018.[81][82] Federal illegality has made it difficult historically to conduct research on CBD.[83] CBD is openly sold in head shops and health food stores in some states where such sales have not been explicitly legalized.[84][85]
Seizure disorder (epilepsy). A specific cannabidiol product (Epidiolex, GW Pharmaceuticals) has been shown to reduce seizures in adults and children with various conditions that are linked with seizures. This product is a prescription drug for treating seizures caused by Dravet syndrome or Lennox-Gastaut syndrome. It has also been shown to reduce seizures in people with tuberous sclerosis complex, Sturge-Weber syndrome, febrile infection-related epilepsy syndrome (FIRES), and specific genetic disorders that cause epileptic encephalopathy. But it's not approved for treating these other types of seizures.
From what I understand, CBD derived from the hemp plant does not have the side effects mentioned above, other than possibly to help reduce the amount of Coumadin/Warfarin needed – either way, a patient on this drug needs to be monitored and regularly tested anyway with their doctor. CBD derived from the marijuana plant (will contain THC) may have them, I do not know, maybe that’s why you mention them. One of the many reasons people take Hemp CBD is that it does NOT have the side effects! People take the Hemp version to help with feelings of fatigue, irritability & anxiousness, it does cause it! It helps to bring the body into balance.
The legality of CBD is probably one of the most discussed topics when it comes to reading about these products. Some publications will state that CBD is legal throughout the entire world, due to the fact that the substance does not contain any psychoactive agents, while other publications will note that CBD is considered a drug and illegal in some countries.
