The endocannabinoid system and its role in homeostasis was discovered in the 1990s. The research shows us that there are two main types of receptors in the human body: CB1 (found in your brain, lungs, and spine) and CB2 (found in your immune system, colon, and spleen). Before the endocannabinoid system discovery revealed that the body naturally produced its own endocannabinoids, we only knew them (cannabinoids) as a diverse group of compounds found in a family of plants that includes hemp.
The first endocannabinoid to be discovered was anandamide, which is named after Ananda, the Sanskrit word for bliss. Anandamide can also be found in chocolate. Many common, popular activities cause your body to release endocannabinoids. To experience this natural process, try going for a long run, or dancing and singing along with your favorite song. Running, singing, and dancing are all known to release endocannabinoids and bring a sense of happiness and well-being.
