Preliminary research indicates that cannabidiol may reduce adverse effects of THC, particularly those causing intoxication and sedation, but only at high doses.[19] Safety studies of cannabidiol showed it is well-tolerated, but may cause tiredness, diarrhea, or changes in appetite as common adverse effects.[20] Epidiolex documentation lists sleepiness, insomnia and poor quality sleep, decreased appetite, diarrhea, and fatigue.[2]

Hemp-producing cannabis has tall, fibrous stalks that are very strong and have very few flowering buds. On the other hand, marijuana strains are short, bushy, and have high amounts of THC. In fact, industrial hemp and medical marijuana are so distinctively different that most lay people wouldn’t be able to tell that they belong to the same genus of plants if they encountered them in the wild!
In nature, Cannabis ruderalis typically has the lowest levels of THC, Cannabis sativa has a higher level of THC than it has CBD, and Cannabis indica has a higher level of CBD than it has THC. However, since man has been cultivating cannabis (and especially Cannabis sativa) for thousands of years, the effects of artificial selections have led to several different types of cannabis even within the same species, depending on the purpose the cannabis was cultivated for.

A review of 25 studies on the safety and efficacy of CBD did not identify significant side effects across a wide range of dosages, including acute and chronic dose regimens, using various modes of administration.xli CBD is present in nabiximols which, as noted earlier, is approved throughout most of Europe and in other countries. Because of this, there is extensive information available with regard to its metabolism, toxicology, and safety. However, additional safety testing among specific patient populations may be warranted should an application be made to the Food and Drug Administration.
More important than legality is understanding if CBD is safe for you. While studies are still ongoing about the long-term safety of CBD usage, most experts agree that it is easily tolerated by most adults with no significant side effects on mood, physiology, or the central nervous system. Many CBD products, including oils and tinctures, also allow you to customize your serving size, which can help you avoid or mitigate any potential side effects.
Due to hemp’s identity as a bioaccumulator, it is incredibly important that any products made using hemp are properly tested for any outside contamination. HempMeds® does just that – three times over – in order to produce the safest products on the market. Our Triple Lab Tested™ process starts at our hemp’s harvest, where it is tested for outside contaminants. Following importation into the U.S., our CBD hemp oil is tested again by an ISO / IEC 17025:2005 accredited lab to check for microbes, mold, heavy metals, and other possible contaminants, as well as for potency of the cannabinoids present. Finally, after our hemp oil is formulated into our many products, they are batch tested to make sure that the final product is ready to be shipped to your door and safely used by you and your family.

In some users, mild side-effects have been noted. These usually include some tiredness or fatigue but is usually not severe enough to interfere with the user’s day-to-day activities. In addition to tiredness, there are also some studies that note appetite changes, weight changes and diarrhea as possible side-effects, but, once again, these particular side-effects have been noted as mild.
Another notable study conducted by Mechoulam was done on mice bred to have a version of type-1 diabetes. The diabetes was designed to manifest right around 14 weeks, so the mice were treated with CBD for the first 7 weeks of their life and then again in another 7 weeks. He concluded that only 30% had developed diabetes compared to the 90-100% given the placebo.
In addition to the research on the use of cannabinoids in palliative treatments for cancer—reducing pain and nausea and in increasing appetite—there are also several pre-clinical reports showing anti-tumor effects of CBD in cell culture and in animal models.xxviii These studies have found reduced cell viability, increased cancer cell death, decreased tumor growth, and inhibition of metastasis (reviewed in McAllister et al, 2015).xxix These effects may be due to the antioxidant and anti-inflammatory effects of CBD;xxx however these findings have not yet been explored in human patients. There are multiple industry sponsored clinical trials underway to begin to test the efficacy of CBD in human cancer patients.

A colleague of Mechoulam’s, Marc Feldman at Imperial College, London, tested CBD on mice that had a version of rheumatoid arthritis. He found that CBD reduced the mice’s inflammation by 50% at the right dosage. Cardiologists working with the mice at Hebrew University have found that a dosage of CBD immediately following a heart attack can reduce infarct size by about 66%.


Cannabis – A type of flowering plant that includes three distinct variations: Cannabis ruderalis, Cannabis indica, and Cannabis sativa. Cannabis has a wide range of industrial and medical applications. It has been used since antiquity for its sturdy fiber, for oils, and for medicinal purposes. However, it has also been used as a recreational drug, a fact that renders the cultivation of cannabis strictly regulated because of some variations including high concentrations of THC.
Unfortunately we cannot guarantee that you would pass a drug test while taking CBD products. Most drug tests are testing for THC and its metabolites only. However, there are drug tests in use that are sensitive enough to detect any and all cannabinoids, including CBD. Many corporations, the U.S. military, and American state and federal governments typically use these more stringent tests – in addition to pain clinics. We encourage consumers to be mindful of their employer’s or clinic’s drug testing policies if they have concerns about using any cannabis product.
Extraction: The method by which CBD oil is processed from hemp plants can be very telling. Some manufacturers extract and process the oil using toxic materials like propane or butane; in most cases, these oils are cheaply priced. Safer extraction and processing agents include ethanol, which cleans the hemp plant of unwanted toxins; and supercritical carbon dioxide extraction, which strips harmful materials from the plant by changing the carbon dioxide’s temperature and pressure settings.
Unpalatable CBD pastes were the first mainstream CBD products, but thankfully Elixinol’s great-tasting organic concentrates elevate the familiar with precise dosing and airless delivery for hygienic administration.

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.
