Cannabidiol (CBD) is a naturally occurring cannabinoid found in cannabis plants, particularly in the hemp plant. Unlike its cousin THC, CBD does not cause a “high” or any psychotropic effects or dependency and is legal in Europe. CBD is one of the major compounds found in hemp, along with flavonoids and terpenoids.
CBD interacts with the central nervous system receptors CB1 and CB2, which are part of the endocannabinoid system. While CBD has a low affinity with these receptors, it has been reported to have interesting benefits for the body. In particular, some studies have suggested that CBD may be helpful in reducing anxiety and improving sleep quality.
Scientific sources that provide evidence of the potential benefits of CBD include the 1993 study by Pertwee on the existence of cannabinoid receptors and the 1992 study by Devane et al. on the isolation and structure of a brain constituent that binds to the cannabinoid receptor. More recent studies, such as “Cannabidiol in Anxiety and Sleep: A Large Case Series” by Shannon et al. (2019) published in The Permanente Journal and “The endocannabinoid system: Essential and mysterious” by Grinspoon MD (2021) published in Harvard Health, have further explored the potential therapeutic benefits of CBD, particularly in the areas of anxiety and sleep. According to Harvard Health, there are studies that suggest CBD may help with both falling and staying asleep.
These studies suggest that CBD may have positive effects on the body without causing the psychoactive effects of THC. However, it is important to note that CBD should be used under the guidance of a healthcare professional and is not intended to diagnose, treat, or cure any condition.
