psychology of addiction

The psychology of addiction involves how the brain's reward system drives repeated behaviors to feel pleasure or avoid discomfort. When someone uses a substance or engages in certain activities, it floods the brain with chemicals like dopamine, creating a pleasurable sensation. Over time, the brain may crave this feeling, leading to compulsive use despite negative consequences. Addiction also involves learned habits, emotional triggers, and changes in decision-making, making it difficult to quit. Understanding this helps explain why addiction is a complex interplay of biological, psychological, and environmental factors requiring comprehensive treatment.
