← Human Body & HealthWhy does compulsive drug use continue, despite negative consequences, in addiction?
A)Homeostatic set points restore balance
B)Dopamine hijacks the reward circuitry✓
C)Prefrontal cortex inhibits impulsivity
D)Serotonin modulates behavioral reinforcement
💡 Explanation
Addiction continues due to dopamine dysregulation; drugs cause a surge of dopamine in the nucleus accumbens, which reinforces drug-seeking behavior, hijacking the brain's reward circuitry, because the brain interprets drug use as highly rewarding. Therefore, compulsive use continues, rather than being inhibited by cognitive control.
