Question

Quizplus · Accepted Answer

A psychotic episode is the most severe adverse reaction to LSD. It can involve symptoms such as delusions, paranoia, and disorganized thoughts and behavior. It can also last for several days and require medical intervention. Flashbacks, elevated heart rate, and frightening hallucinations are all possible adverse reactions to LSD, but they are typically less severe than a full-blown psychotic episode.
