When taken by mouth: 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.

To make this more concrete, let’s use an example here. This is a high-CBD hemp oil product made from industrial hemp. It has a concentration of CBD between 18% and 24%. This means that it has 18%–24% parts CBD dissolved in the actual oil, which is composed by other substances. So 18%–24% is pure CBD, and the rest are hemp oil extracts and other fatty acid substances.
Laboratory evidence indicated that cannabidiol may reduce THC clearance, increasing plasma concentrations which may raise THC availability to receptors and enhance its effect in a dose-dependent manner.[21][22] In vitro, cannabidiol inhibited receptors affecting the activity of voltage-dependent sodium and potassium channels, which may affect neural activity.[23] A small clinical trial reported that CBD partially inhibited the CYP2C-catalyzed hydroxylation of THC to 11-OH-THC.[24] Little is known about potential drug interactions, but CBD-mediates a decrease in clobazam metabolism.[25]

Cannabidiol has antipsychotic effects. The exact cause for these effects is not clear. But cannabidiol seems to prevent the breakdown of a chemical in the brain that affects pain, mood, and mental function. Preventing the breakdown of this chemical and increasing its levels in the blood seems to reduce psychotic symptoms associated with conditions such as schizophrenia. Cannabidiol might also block some of the psychoactive effects of delta-9-tetrahydrocannabinol (THC). Also, cannabidiol seems to reduce pain and anxiety.
Since 2014, NuLeaf Naturals – our Editor’s Pick – has been committed to creating high-quality CBD oil products. As one of the oldest and most reviewed companies in the industry, NuLeaf Naturals has established themselves as a trustworthy CBD manufacturer. All of their products are tested by third party labs and their cannabinoid profile is impressive. They offer a unique range of concentrations for their organic CBD products ranging from 240mg to 4,850mg.

But because all these products are illegal according to the federal government, cannabis advocates are cautious. “By and large, the federal government is looking the other way,” says Paul Armentano, deputy director of the Washington, DC–based National Organization for the Reform of Marijuana Laws (NORML), but until federal laws are changed, “this administration or a future one could crack down on people who produce, manufacture, or use CBD, and the law would be on its side.”
The tincture is available in three strengths: 500mg, 1,000mg, and 3,000mg. Prices range from $0.04 to $0.07 per mg, depending on the concentration, which makes the tincture very low-priced compared to oils from most competing brands. Medterra also offers a 30-day satisfaction guarantee and will issue full refunds for all returns. In addition to the tincture, Medterra also offers CBD capsules in 25mg and 50mg concentrations.

The 2014 Farm Bill[86] legalized the sale of "non-viable hemp material" grown within states participating in the Hemp Pilot Program.[53] This legislation defined hemp as cannabis containing less than 0.3% of THC delta-9, grown within the regulatory framework of the Hemp Pilot Program.[87] The 2018 United States farm bill allowed for interstate commerce of hemp derived products, though these products still fall under the purview of the FDA.[88][89]


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.

Based in Los Angeles, Calm by Wellness plans to be among the largest hemp-growing and CBD extraction facilities in the world by the end of 2019. The company sources their hemp from Colorado and uses clean CO2 technology to extract their CBD and other cannabinoids (no THC though!). The company is also GMP and ISO9001 food-grade manufacturer certified.
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%.
The tincture is available in three strengths: 500mg, 1,000mg, and 3,000mg. Prices range from $0.04 to $0.07 per mg, depending on the concentration, which makes the tincture very low-priced compared to oils from most competing brands. Medterra also offers a 30-day satisfaction guarantee and will issue full refunds for all returns. In addition to the tincture, Medterra also offers CBD capsules in 25mg and 50mg concentrations.
Various strains of "medical marijuana" are found to have a significant variation in the ratios of CBD-to-THC, and are known to contain other non-psychotropic cannabinoids.[55] Any psychoactive marijuana, regardless of its CBD content, is derived from the flower (or bud) of the genus Cannabis. As defined by U.S. federal law, non-psychoactive hemp (also commonly-termed industrial hemp), regardless of its CBD content, is any part of the cannabis plant, whether growing or not, containing a ∆-9 tetrahydrocannabinol concentration of no more than 0.3% on a dry-weight basis.[56] Certain standards are required for legal growing, cultivating, and producing the hemp plant. The Colorado Industrial Hemp Program registers growers of industrial hemp and samples crops to verify that the dry-weight THC concentration does not exceed 0.3%.[56]
At the top of our ranking is Portland-based Lazarus Naturals, which has honed a reputation for high-quality, affordable CBD. Their consciously crafted CBD is sourced from organic, Oregon-grown hemp which the company controls from seed to sale. With low prices, a robust assistance program, free shipping, and a 30-day, no questions asked return policy, you really can’t go wrong with Lazarus Naturals.

“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.
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.
Cannabidiol is a chemical in the Cannabis sativa plant, also known as marijuana or hemp. Over 80 chemicals, known as cannabinoids, have been identified in the Cannabis sativa plant. While delta-9-tetrahydrocannabinol (THC) is the major active ingredient in marijuana, cannabidiol is also obtained from hemp, which contains only very small amounts of THC.
Dispensaries: In states where marijuana is legal for recreational use, dispensaries are a common sight. They are much rarer in states with more restrictions. In states that permit the use of medical marijuana, hemp-based CBD oils do not normally require a prescription but marijuana-based oils do. Like brick-and-mortar locations, dispensaries offer more customer service. However, as noted, this may not be an option depending on the buyer’s state of residence. Also, CBD oil prices tend to be significantly higher at dispensaries.

A condition in which a transplant attacks the body (graft-versus-host disease or GVHD). Graft-versus-host disease is a complication that can occur after a bone marrow transplant. In people with this condition, donor cells attack the person's own cells. Early research shows that taking cannabidiol daily starting 7 days before bone marrow transplant and continuing for 30 days after transplant can extend the time it takes for a person to develop GVHD.
