Question

Quizplus · Accepted Answer

The drug described is most likely cocaine, which is known for its ability to block the reuptake of dopamine, serotonin, and norepinephrine, leading to feelings of euphoria, heightened alertness, and increased confidence. Caffeine also increases alertness but does not impact dopamine or serotonin. Heroin causes feelings of euphoria but does not impact norepinephrine or alertness. Marijuana does not block reuptake of neurotransmitters and typically does not lead to intense euphoria or increased confidence.
