In recent years studies have shown that your brain has a cannabis system, namely the endocannabinoid system. How does this work? You have neurons and neural circuits. Neurons are long cells that keep their distance from each other. This distance is bridged by. These travel from one cell to another and attach themselves to molecules. The molecules that they attach to are receptors. One of these neurotransmitters is the endocannabinoid. If we are scared, stressed or in pain, the endocannabinoid is released. The transmitter then travels to our endocannabinoid system to release the dust from weed and we get rid of the bad feeling!
