← Human Body & HealthA person recovering from opioid addiction experiences intense drug cravings when seeing old friends who still use. Why does this cue trigger craving?
A)Increased liver enzyme production clears opioids faster
B)Amygdala down-regulation reduces fear response
C)Hippocampal damage limits memory recall accuracy
D)Associative learning links cue to dopamine release✓
💡 Explanation
Associative learning causes the cue (seeing friends) to become strongly linked with the rewarding effects of the drug, because the nucleus accumbens releases dopamine upon seeing the cue. Therefore, cue exposure triggers intense craving, rather than changes in liver enzymes, amygdala function, or memory recall.
