Effects of Ayahuasca on the Recognition of Facial Expressions of Emotions in Naive Healthy Volunteers
Journal of Clinical Psychopharmacology – April 13, 2021
Summary
Despite prior evidence that other psychedelics like psilocybin can alter emotional processing, a drug study with 22 healthy volunteers revealed Ayahuasca, a potent hallucinogen, did not change facial emotion recognition compared to a placebo. While participants reported well-being and visual effects, some experienced transient anxiety. Tolerability was acceptable, despite common nausea. This finding in psychology and pharmacology, considering the biochemical analysis of alkaloid stability, suggests Ayahuasca’s unique neurotransmitter receptor influence on behavior may differ from other medicines, requiring further exploration in drug studies.

Effect of an Hallucinogenic Agent on Verbal Behavior
Psychological Reports – October 01, 1963
Summary
A single individual receiving a 9mg dose of Psilocybin, a potent hallucinogen, initially experienced enhanced verbal communication quality for 1.5 hours. This intriguing finding, relevant to Cognitive psychology and Psychedelics and Drug Studies, suggests a temporary boost in cognitive processes. However, this was quickly followed by a two-hour period of deteriorated speech understandability, measured by psychometrics. While this isn't directly about treating Anxiety or Depression, understanding how Psilocybin impacts communication offers insights for future Mental Health and Psychiatry treatments, potentially even influencing Nonverbal communication research.
Abstract
Cloze analysis was used to assess the “understandability” of the spontaneous speech of a normal S who had received 9 mg. of psilocybin. This drug s...

Therapeutic Usefulness of Hallucinogenic Drugs as a Function of their Chemical Structure
Pharmacopsychiatry – January 01, 1975
Summary
A compelling finding reveals (+)-Naloxone, a compound of interest in Pharmacology, can block effects of the potent hallucinogen Lysergic acid diethylamide. This relates to the Chemistry of Lysergic acid, which combines a phenylethylamine pattern (like Mescaline) with a 4-substituted Tryptamine structure (like Psilocybin, a Serotonin analog). Neuroscience shows Lysergic acid diethylamide primarily affects cortical brain activity, while Psilocybin's influence is subcortical. These insights, crucial for Psychedelics and Drug Studies, illuminate Neurotransmitter Receptor Influence on Behavior and Psychology, distinguishing these substances from others like Cannabis.
Abstract
D-lysergic acid diethylamide (LSD) displays (1) the phenylethylamine pattern present in mescaline, cyclazocine and catecholamines and (2) the 4-sub...
A proposal to evaluate mechanistic efficacy of hallucinogens in addiction treatment
The American Journal of Drug and Alcohol Abuse – August 22, 2013
Summary
Hallucinogens like Psilocybin offer significant, long-term benefits for drug abstinence, a compelling finding given current addiction treatment failures. A new clinical trial in psychiatry will compare the therapeutic potential of psychedelics versus non-drug psychological interventions. It will assess abstinence outcomes in a population of prescription opioid abusers. Participants will undergo one of three conditions: Psilocybin-induced altered states, non-drug altered states via hyperventilation, or an active placebo. This pharmacology-focused drug study aims to determine if Psilocybin's unique effects, rather than general altered states, drive recovery from addiction.
Abstract
Current treatments for addiction are frequently ineffective. Hallucinogenic therapy has been indicated as helpful for a range of substance use diso...
Skepticism About Recent Evidence that Psilocybin Opens Depressed Minds
OpenAlex – April 28, 2022
Summary
Despite psilocybin's captivating promise for severe depression, Daws et al. (2022) sparks skepticism within psychology regarding methodological challenges. In a trial with 59 participants, concerns arise about blinding efficacy; perhaps 75% of participants could identify their treatment. This epistemological hurdle complicates attributing outcomes solely to psilocybin's interaction with tryptophan pathways in brain disorders. Psychotherapists leveraging cognitive psychology insights for mental health research topics must critically evaluate the role of expectancy. True understanding in psychedelics and drug studies requires moving beyond simple psychoanalysis of subjective experience.
Abstract
Here we raise issues in Daws et al. (2022) published in Nature Medicine.
