"Hallucinogen is a hallucinogenic drug. Surely Professor Romanka knows the true purpose of this drug." The boy paused, his facial muscles stiffening.
Alice hesitated for a long moment as she held the pathology report. Then it dawned on her. "Maybe… I have a good idea why Professor Romanka gave her this drug."
The boy was perplexed when he heard this and asked for confirmation, "Tell me. What's the reason? This drug can be toxic. Though I don't think the dosage is fatal, it's higher than the usual dose used purely for management of illnesses."
"As you know, this drug causes hallucination."
"Uh huh."
"Generally, when a patient has bipolar disorder, for example, or is anxious and has insomnia, taking this drug at a low dose can have a calming effect. However, at this dosage prescribed here, the patient taking it will hallucinate."
"Hallucinate…"
"Uh huh."
