Cannabis oil, whether CBD, THC, or both, is extracted from flowers, leaves, and the stalk of the plant mainly using different solvents – butane, CO2, ethanol, petroleum ether, naphtha, olive oil, or whole plant extraction (that makes Rick Simpson Oil). Depending on whether you’re extracting oils at home or getting them from a licensed producer, the process ranges from simple to incredibly complex.
Cannabidiol can be taken into the body in multiple different ways, including by inhalation of cannabis smoke or vapor, as an aerosol spray into the cheek, and by mouth. It may be supplied as an oil containing only CBD as the active ingredient (no added THC or terpenes), a full-plant CBD-dominant hemp extract oil, capsules, dried cannabis, or as a prescription liquid solution.
Cannabidiol, or CBD for short, is a phyto-cannabinoid found in cannabis plants. However, it does not cause the same psychoactive effects as other naturally occurring cannabinoids (such as tetrahydrocannabinol, or THC). CBD induces feelings of sleepiness and tranquility, making it suitable for insomnia and other sleep disorders; CBD can be used to alleviate symptoms of epilepsy, diabetes, and anxiety disorders, as well. Legality is an issue for some; all 50 states have laws governing the sale, possession, and use of CBD, and they vary significantly (see the table below for a full analysis).
“Placebo response always needs to be taken into account for any treatment being studied,” says Baron. “Placebo response is actually quite high in many pharmaceutical trials, for example. In fact, there are many treatment trials for various medications and other treatments where benefit responses to placebo are actually higher than the treatment itself being studied.”
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.
