Before we discuss combining these two cannabinoids, we'll need to understand how they work individually.
THC, short for tetrahydrocannabinol, is a compound found in cannabis (hemp and marijuana) that consists of 21 carbon atoms, 30 hydrogen atoms, and two oxygen atoms. There are various forms of THC with nuances in effects based on the location of the double bond on their molecule. For instance, Delta-9 THC has a bond on its ninth carbon chain, and Delta-8 THC on its eighth carbon chain.
THC offers psychoactive effects because it resembles a compound our bodies make called "anandamide." Anadaminide is a chemical messenger used in our endocannabinoid system, which helps regulate various functions such as emotional processes, memory, sleep, appetite, pain management, and much more. This chemical messenger binds to the CB1 receptors in the endocannabinoid system.
Due to THC's resemblance to anandamide, it can bind to the same receptors, offering relaxation, contentment, increased aesthetic appreciation, laughter, and other effects commonly associated with cannabis.
CBD is short for cannabidiol. Like THC, it consists of 21 carbon atoms, 30 hydrogen atoms, and two oxygen atoms. However, CBD is an isomer of THC, meaning it comprises the same building blocks but in a different structure.
Regarding its mechanisms and effects, CBD has a minimal binding affinity to the
CB1 and CB2 receptors of the endocannabinoid system. However, CBD can enhance or inhibit the activation of other receptors in the human body. For instance, according to
research published in 2020, CBD can improve the activity of serotonin (one of the brain's "happy chemicals") 1A receptors. However, CBD's interaction with the body changes when you add THC.
