Which of the following is NOT a symptom associated with LSD use?

LSD (lysergic acid diethylamide) is a powerful hallucinogenic drug known for its significant effects on perception, mood, and cognitive processes. The symptoms associated with LSD use often include anxiety, depression, and visual hallucinations.

Anxiety can occur during an LSD experience as users might feel heightened sensory perceptions, leading to overwhelming feelings or paranoia. Depression may also manifest, particularly as the effects of the drug begin to wear off, or if the individual has a predisposition to mood disorders. Visual hallucinations are one of the hallmark effects of LSD, as the drug alters one’s sensory perceptions, causing users to see patterns, distortions, and vivid imagery that aren’t present in reality.

In contrast, pupillary constriction is not typically associated with LSD use; rather, users often experience pupillary dilation. This physiological response is frequently observed with stimulants and hallucinogens, while constriction is more characteristic of opioids. Therefore, the correct answer identifies a symptom that does not correspond with the expected effects of LSD.
