A number of health benefits of CBD oil have been tested in vitro (i.e., with cells and tissues instead of living beings) as well as via animal studies, and some have even been examined in human clinical studies. However, until a health benefit has been validated by peer-reviewed, double-blind, placebo-controlled clinical studies, it's impossible to know for sure if CBD – or any supplement – actually has the purported effect.
Also referred to as a full-spectrum extract, whole plant hemp extract contains all of the available benefits within the hemp material. By keeping all of the plant components, whole plant hemp extract benefits from the synergistic properties between the components. Scientists have found that plant components interact with one another to create an enhanced effect (compared to the component alone).
Most of the CBD oil products independently tested have been shown to have inconsistent and insufficient dosage levels, often outrageously below stated claims. For instance, a bottle claiming 250mg of CBD actually had 7mg. This is unfortunately quite common. CBD Isolate is much more reliable for accurate dosing, so you are much more likely to get what you pay for. And it doesn’t cause the stomach upset that oil does.
As with a fermented food like kombucha, slight natural variations are normal and to be expected in a product such as CBD oil because it is made from living plants. Changes in the weather, soil, and water can all impact the biology of the source material. While we verify Certificates of Analysis (and take many other criteria into consideration during our review process), even the most reputable five-star companies have no way to control for every variable in this organic process.
Prescription medicine (Schedule 4) for therapeutic use containing 2 per cent (2.0%) or less of other cannabinoids commonly found in cannabis (such as ∆9-THC). A schedule 4 drug under the SUSMP is Prescription Only Medicine, or Prescription Animal Remedy – Substances, the use or supply of which should be by or on the order of persons permitted by State or Territory legislation to prescribe and should be available from a pharmacist on prescription.
In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few. For a more comprehensive look at these and other studies, visit our medical research and education page.
In the United States, non-FDA approved CBD products are classified as Schedule I drugs under the Controlled Substances Act. This means that production, distribution, and possession of non-FDA approved CBD products is illegal under federal law. In addition, in 2016 the Drug Enforcement Administration added "marijuana extracts" to the list of Schedule I drugs, which it defined as "an extract containing one or more cannabinoids that has been derived from any plant of the genus Cannabis, other than the separated resin (whether crude or purified) obtained from the plant." Previously, CBD had simply been considered "marijuana", which is a Schedule I drug.
