AN INTRODUCTION TO THE
ENDOCANNABINOID SYSTEM (ECS)

EDUCATIONAL SERIES: MEDICAL MARIJUANA 101

 

Human skeleton and muscle with dots to signify where the CB1 and CB2 receptors are.

Your body naturally creates substances called endocannabinoids, and some of these are similar to the cannabinoids found in marijuana.

The body’s ECS sends “signals” (endocannabinoids) to “receivers” (CB1 and CB2 receptors) to help balance your body’s sleep cycle, appetite level, and more.

The cannabinoids in marijuana act in a similar way by connecting to the CB1 and CB2 “receivers” which can lead to different effects (e.g., increased appetite, changes in mood). But cannabinoids in marijuana are not identical to human cannabinoids and they are not the only component of marijuana.

It is not yet completely understood whether and how medical marijuana may help with a number of medical conditions.
