Increased reactivity of the paraventricular nucleus of the hypothalamus and decreased threat responding in male rats following psilocin administration.
Nature communications – June 22, 2024
Summary
Psilocin, the active compound in magic mushrooms, alters how the brain processes threats through its effects on a key stress-response region. Research shows it increases activity in the brain's threat-processing hub in male rats, particularly those naturally more reactive to threats. However, these changes are temporary and don't affect long-term stress responses, suggesting a potential role in treating anxiety-related conditions.

Psychedelic Microdosing among Young Adults from Southern California
Journal of Psychoactive Drugs – February 10, 2024
Summary
Nearly one in five young adults attempting psychedelic microdosing actually take standard, psychoactive doses, risking adverse effects. Among 2,396 young adults, only 3% (74 individuals) had ever microdosed, despite 12% awareness. Psilocybin (70%) and lysergic acid diethylamide (57%) were the most common hallucinogens. This underscores the need for Medicine, Psychiatry, and Psychology to provide clear guidance on these chemical synthesis and alkaloids, for both Clinical Psychology and broader Psychedelics and Drug Studies.
Abstract
Despite common depictions in the media, there is little scientific evidence on microdosing psychedelic drugs. We assessed awareness, prevalence, an...

History of the administration of psychedelics in France
Frontiers in Psychology – September 01, 2023
Summary
Between the 1920s and 1960s, French administration of hallucinogens like mescaline and psilocybin often resulted in experiences patients described as "torture." Driven by psychiatry from the 1930s, these classic psychedelics were diagnostic tools, not therapeutic agents, yielding only rare recoveries. Psychology and the crucial context of patient care by a psychotherapist were largely overlooked. This historical approach, detailed in Historical and Scientific Studies, explains France's current hesitation during the psychedelic renaissance, contrasting with modern Complementary and Alternative Medicine Studies.

Psychedelic drug abuse potential assessment for new drug applications and controlled substance scheduling: A United States perspective
Journal of Psychopharmacology – January 01, 2023
Summary
Evaluating hallucinogens for medicine and psychiatry requires tailored substance abuse assessments. While many nonclinical techniques, including neurotransmitter receptor influence on behavior, adapt well to psychedelics, standard human abuse trials need modification. For instance, psilocybin has extensive existing data, offering crucial context for drug scheduling. Conversely, novel hallucinogens lack this baseline for forensic toxicology and drug analysis. Psychology and Psychedelics and Drug Studies advocate for flexible approaches, ensuring safety and valid outcomes in pharmaceutical development, especially given their non-reinforcing nature, distinct from typical drugs of abuse.
Abstract
Background: Psychedelics are an increasingly active area of research and pharmaceutical development. This includes abuse potential assessment to be...

Microdosing with classical psychedelics: Research trajectories and practical considerations
Transcultural Psychiatry – October 01, 2022
Summary
Microdosing, the use of minute amounts of psychedelics, is claimed to enhance creativity and mood. Psychology explores how substances like psilocybin, lysergic acid diethylamide, and mescaline—compounds often from chemical synthesis or natural alkaloids—influence consciousness and perception. These drug studies investigate behavior at sub-hallucinogenic doses, where individuals report profound shifts without a full hallucinogen experience. Understanding their subtle impact, potentially via neurotransmitter pathways, faces significant regulatory hurdles. The field aims to distinguish genuine effects from expectation.
Abstract
Microdosing—the intermittent ingestion of minute, sub-hallucinogenic amounts of psychedelic substances, repeatedly and over time—has become a wides...
Default Mode Network Modulation by Psychedelics: A Systematic Review
The International Journal of Neuropsychopharmacology – October 21, 2022
Summary
Psychedelics like LSD and psilocybin profoundly alter brain activity, consistently disrupting the Default Mode Network (DMN), a key brain region for self-referencing and linked to various psychological conditions. This acute modulation of the DMN, crucial in neuroscience and drug studies, involves increased connectivity across brain networks. Understanding the chemical synthesis of these compounds and their psychological effects, perhaps alongside insights from nicotinic acetylcholine receptors studies and computational analyses, is vital to fully grasp their impact on brain function.

Predictors of Psychedelic Experience: A Thematic Analysis
Journal of Psychoactive Drugs – October 05, 2022
Summary
Nature and music can de-escalate adverse reactions to psychoactive substances like Psilocybin and MDMA. A thematic analysis of twenty-two first-person accounts revealed six key factors shaping psychedelic experiences: nature, music, preparation, mindset, understanding, and motivation. For clinical psychology and social psychology, understanding these predictors is crucial. Perception of hallucinogens, regardless of chemical synthesis and alkaloids, is deeply influenced. This work in Psychedelics and Drug Studies highlights how a careful set of conditions can mitigate harm and influence neurotransmitter receptor influence on behavior, aiding psychotherapists in harm reduction.
