The binding of endocannabinoids has been shown to play a critical role in fine motor control. Specifically, it has been shown that CB1 receptor binding is decreased in patients with neurodegenerative diseases such as Parkinson’s and Huntington’s disease. In contrast, CB1 receptors have a lesser influence on gross motor control due to the lower concentration of receptors in the cerebellum, which is responsible for coordinating gross motor control <ref name="review"/>. | ||

CB1 receptors are responsible for mediating the anti-anxiety effects of cannabinoids, like THC. In low doses, cannabinoids reduce anxiety; however, high doses of cannabinoids act to increase anxiety <ref name="toxic" /> | CB1 receptors are responsible for mediating the anti-anxiety effects of cannabinoids, like THC. In low doses, cannabinoids reduce anxiety; however, high doses of cannabinoids act to increase anxiety <ref name="toxic" />. This is one reason why synthetic cannabinoids like K2, an extremely potent synthetic cannabinoids, produces the harmful side effect of extreme anxiety. | ||
