Question

Quizplus · Accepted Answer

Cocaine is metabolized more quickly than amphetamines, not more slowly. This is due to the fact that cocaine blocks the reuptake of neurotransmitters, leading to a build-up of dopamine and noradrenaline in the synaptic cleft, whereas amphetamines actually increase the release of these neurotransmitters.
