When dopamine is released in this area, you feel good. How Does Marijuana Affect Dopamine? The cannabinoids in marijuana do not act on dopamine neurons directly.
Instead, they act on the endocannabinoid system. Cannabinoid receptors are found in many brain areas that have dopamine neurons. However, dopamine neurons in the reward pathway are inhibited by GABA neurons which do have cannabinoid receptors.
What happens when you inhibit an inhibitor? The dopamine neurons become disinhibited, and more active. GABA is naturally inhibited by other cannabinoids produced by the brain. The action of natural cannabinoids, known as endocannabinoidsis believed to play an essential role in the release of dopamine in day-to-day functions.
