Repeated use of marijuana affects the parts of the brain that controls memory, attention, and learning. "Cannabinoids work by influencing the endocannabinoid system, specifically the brain and central nervous system. THC gets its potent effect because it binds well with the Cannabinoid 1 receptor (known as CB1), while CBD exhibits low affinity for either CB1 or CB2 receptors. Instead, CBD acts as an indirect antagonist of these receptors."
