Cannabis oils may contain various concentrations of CBD, tetrahydrocannabinol (THC), and minor cannabinoids, mainly depending on the cannabis variety used for extraction. The most popular product currently is CBD oil, but for example cannabigerol (CBG)-rich oil has been spotted as well , and others will very likely follow soon. The THC-rich type of cannabis oil has already been known for some years, and is generally known under the name “Simpson oil” . Terpenes may or may not be present in these products, depending on the preparation method used . Because they are highly volatile, elevated temperatures (such as those applied during drying of plant materials, or during the evaporation of solvents) may result in a significant loss of terpene components . However, it is possible to capture evaporated terpenes by condensation, and reintroduce them back into the final oil. Additional ingredients may be added to further adjust properties such as color, viscosity, taste, or shelf-life stability.
One of the strongest nutraceutical CBD oils is called Charlotte’s Web, with a 50mg dose. Charlotte’s Web is produced in Colorado by the Stanley Brothers, and named after Charlotte Figi, a girl who became famous in the US after her frequent seizures, brought on by the rare Dravet syndrome, were greatly reduced when she started taking CBD oil aged five. The company makes THC products too and is extremely successful, having just offered shares on the Canadian securities exchange, raising about $100m.
As an alternative health regimen, CBD holds particular appeal to women, said Gretchen Lidicker, the health editor of Mindbodygreen, a wellness website based in New York, and the author of “CBD Oil Everyday Secrets.” Noting the preponderance of female-run CBD businesses, Ms. Lidicker, 26, said that it is “no surprise that women are leading the CBD movement.”
The vast majority of CBD oils come in bottles measuring either 15 milliliters (mL), or 0.5 ounces; or 30 mL, or 1 ounce. However, CBD concentration is more important than bottle size. Concentration refers to the ratio of hemp oil solution (measured in mL) compared to the amount of CBD cannabinoid (measured in milligrams, or mg). A 15-mL bottle may contain 100 mg of CBD, 300 mg, 500 mg, or more. The higher the mg amount, the stronger the CBD oil will be. For this reason, the ‘mg’ measurement is also referred to as the oil’s strength; i.e., 400-mg oil might be called 400-strength oil.
There has been a fair amount of confusion surrounding the legality of CBD oil. But while the vast majority of cannabinoids are controlled substances under the Misuse of Drugs Act, rest assured that CBD oil is legal across the UK for medicinal purposes, provided it has been derived from an industrial hemp strain that is EU-approved. These strains contain very little to no THC (the psychoactive cannabinoid).
Despite this, CBD is something nobody knows much about, and certainly nobody is monitoring it properly. CBD is widely marketed as a supplement, despite the Food and Drug Administration saying it does not qualify as such (this is because it is an active ingredient in drugs which are either approved or under investigation to be approved). CBD goes largely unregulated by the agency; on the FDA’s FAQ page, a vague answer maintains there are “many factors in deciding whether or not to initiate an enforcement action.” The Department of Agriculture handles research grants and pilot programs for hemp, but that’s where its involvement ends.
