dopamine theory of addiction

The dopamine theory of addiction suggests that substances or behaviors that people become addicted to trigger the release of dopamine, a neurotransmitter associated with pleasure and reward, in the brain. When you engage in these activities—like using drugs, gambling, or even social media—the brain experiences a rush of dopamine, reinforcing the behavior. Over time, the brain adapts by reducing its natural dopamine production, leading to a stronger craving for the substance or activity to achieve the same pleasurable feelings. This creates a cycle of dependency, making it difficult to quit despite negative consequences.
