Question

Quizplus · Accepted Answer

Reed's behavior changes suggest the possibility of amphetamine abuse. Amphetamines can cause aggressive behavior, paranoia, and reduced appetite. LSD can also cause paranoia and unusual behavior, but it is not typically associated with aggression or appetite suppression. Barbiturates and alcohol can lead to behavioral changes, but they are more often associated with sedation and depression rather than aggression and paranoia.
