Okay kiddo, let me try to explain this to you. Do you know what a plant called marijuana is? Yes, it is a plant that has some chemical compounds in it which are called cannabinoids. Our body also has some naturally occurring chemicals called endocannabinoids which help our body in various ways like regulating our moods, pain, and appetite.
Now, sometimes our body makes too many endocannabinoids and sometimes it doesn't make enough. When our body makes too many of them, it can create problems like anxiety or paranoia. Similarly, if our body doesn't make enough of them, we can feel pain or become really hungry.
An endocannabinoid reuptake inhibitor is a medicine that can help us balance the amount of endocannabinoids in our body. It works by blocking the natural process of our cells that are responsible for cleaning up the extra endocannabinoids. As a result, the level of endocannabinoids in our body increases, which helps us to feel better.
Think of it like this, imagine you have a toy box, and you have too many toys in it. You feel overwhelmed and cannot find your favorite toy. So, you take out some toys and put them on the floor which makes you feel better. Endocannabinoid reuptake inhibitor does something similar, it stops the cells from taking out some endocannabinoids when there are already enough in our body.
But remember, children should never take any medicine without the doctor's advice.
