Dopamine is associated with the brain's reward system. Addiction often involves the dysregulation of the reward pathway, where dopamine plays a key role in feelings of pleasure and motivation that drive addictive behaviors. Serotonin is more related to mood, sleep, etc., and not primarily linked to addiction.
