Lysergic acid diethylamide (LSD) intoxication

Overview


Plain-Language Overview

Lysergic acid diethylamide (LSD) intoxication occurs when a person uses the drug LSD, which affects the brain and nervous system. This substance alters how the brain processes information, leading to changes in perception, mood, and thought patterns. People may experience visual hallucinations, distorted sense of time, and intense emotions. The drug primarily impacts the central nervous system, causing both psychological and physical effects. These changes can be unpredictable and may result in confusion, anxiety, or panic. The effects usually begin within an hour of ingestion and can last for several hours. Because LSD affects brain function, it can significantly alter a person's behavior and awareness.

Clinical Definition

Lysergic acid diethylamide (LSD) intoxication is a condition characterized by the acute effects of LSD, a potent serotonergic hallucinogen that primarily acts as a partial agonist at 5-HT2A receptors in the brain. The intoxication results in profound alterations in perception, cognition, and mood, including visual and auditory hallucinations, synesthesia, and distorted time perception. LSD is typically ingested orally and rapidly absorbed, with effects peaking within 2 to 4 hours and lasting up to 12 hours. The condition is significant due to its potential to cause psychological distress, impaired judgment, and risk of injury. Physical symptoms may include mydriasis, tachycardia, hypertension, and hyperthermia. Diagnosis is clinical, based on history and characteristic symptoms, as there are no routine laboratory tests for LSD. The condition is distinct from other intoxications by its unique hallucinogenic profile and serotonergic mechanism.
