WGU D345 Psychopharmacology Hallucinogens 2026/2027 | 10+ Questions & Answers | LSD, Psilocybin, PCP, Ketamine & HPPD – Western Governors University

This WGU D345 Psychopharmacology Hallucinogens 2026/2027 study resource provides 10+ focused questions and answers covering the major classes of hallucinogens, their psychopharmacologic effects, mechanisms, clinical manifestations, and important adverse effects. The four-page document distinguishes serotonergic hallucinogens (psychedelics) from dissociative hallucinogens, with specific coverage of LSD, mescaline/peyote, psilocybin, DMT/ayahuasca, phencyclidine (PCP), ketamine, and dextromethorphan (DXM). It is designed as a concise D345 review for students who need rapid reinforcement of high-yield hallucinogen concepts. The serotonergic hallucinogen section examines psychedelic alterations in sensory perception, including visual distortion, changes in shapes and colors, altered time perception, and other perceptual abnormalities. It reviews lysergic acid diethylamide (LSD), including onset and duration of effects, as well as mescaline, psilocybin, and dimethyltryptamine (DMT). The document also introduces Hallucinogen Persisting Perception Disorder (HPPD) as an important adverse outcome characterized by persistent visual or sensory disturbances after hallucinogen exposure. The dissociative hallucinogen section focuses on altered connections between perception, the body, and the surrounding environment. High-yield concepts include depersonalization and derealization, along with antagonism of the glutamatergic NMDA receptor. PCP is reviewed in relation to behavioral disturbance, analgesia, excited states, and nystagmus, while ketamine is discussed as a dissociative agent with legitimate anesthetic and analgesic applications as well as profound dissociative effects at other exposures. The final section addresses dextromethorphan (DXM), an ingredient found in OTC cough preparations that can produce dissociative effects at excessive doses through NMDA-related pharmacology. Taken together, the material helps students differentiate serotonergic psychedelics from NMDA-antagonist dissociatives and associate representative substances with their characteristic mechanisms, perceptual changes, clinical findings, and adverse effects. Relevant Students: This document is particularly relevant to WGU D345 students, Western Governors University students, psychopharmacology students, psychiatric-mental health nursing students, PMHNP students, MSN and DNP students, advanced practice nursing students, behavioral health students, substance-use pharmacology students, and learners preparing for assessments involving hallucinogens and psychoactive substances. The WGU and D345 identifiers are explicitly displayed on the document's first page. Referenced Academic/Professional Material: The document covers established psychopharmacology concepts involving serotonergic psychedelics, dissociative agents, NMDA receptor antagonism, HPPD, depersonalization, derealization, and hallucinogen-related perceptual effects. However, it does not provide a complete bibliographic citation to a textbook, peer-reviewed journal, or professional guideline. Therefore, no unsupported book or journal reference should be attributed to the uploaded material.
