Humans have the endocannabinoid system, and we naturally respond to the influx of cannabinoids from the cannabis plant. The endocannabinoid system is made up of neurotransmitters and cannabinoid receptors (CB1 and CB2), which are spread throughout the entire body. CB1 receptors are found in largest concentrations in your brain and central nervous system, while CB2 receptors are more commonly present in peripheral organs, especially cells involved with the immune system. The endocannabinoid system, along with its receptors and neurotransmitters creates a communication network between the vital systems in your body, regulating a vast range of biological functions, such as sleep cycle, mood stability, pain and pleasure perception, appetite, and much more. When administered, CBD oil stimulates the cannabinoid receptors and may positively impact your body and brain. Moreover, it prompts the body to produce more of its natural cannabinoids.
