Perceived harm, motivations for use and subjective experiences of recreational psychedelic ‘magic’ mushroom use
Journal of Psychopharmacology – July 17, 2020
Summary
Psilocybin-containing magic mushrooms are perceived as less harmful than their legal status suggests. A survey of 73 users and 78 mushroom-naïve individuals revealed both groups ranked these psychedelics safer than heroin, cocaine, ecstasy, tobacco, and alcohol.

Ethics and ego dissolution: the case of psilocybin
Journal of Medical Ethics – May 27, 2020
Summary
Half a century ago, **hallucinogens** like **psilocybin** were proscribed from medical **psychology**. Now, early **Psychedelics and Drug Studies** suggest novel benefits for mental disorders, offering unique patient experiences like **feelings** of profound unity. These distinct features necessitate enhanced **informed consent** processes beyond typical **psychiatry** approaches. As these **chemical synthesis and alkaloids** move towards **mainstream** clinical use, **psychotherapists** must address novel risks, drawing on **social psychology** and **Complementary and Alternative Medicine Studies** for ethical integration.
Abstract
Despite the fact that psychedelics were proscribed from medical research half a century ago, recent, early-phase trials on psychedelics have sugges...
Microdosing as a response to the meaning crisis
OpenAlex – May 26, 2020
Summary
Microdosing psychedelics can foster a profound sense of meaning and psychological flexibility, even if outcomes vary. Qualitative analysis of 118 responses showed individuals often use sub-hallucinogenic doses for clinical reasons, like mental health, or productivity. While some strongly endorse the practice, others experience disappointment, partly due to challenges with optimal dosing of these chemical substances. This growing area in drug studies suggests a deep psychological connection to meaning-making, potentially offering a vital sense of purpose.
Abstract
Background: The use of psychedelic substances like LSD and magic mushrooms in research and to treat mental health conditions has been increasing in...
Pharmacokinetics and subjective effects of 1P‐LSD in humans after oral and intravenous administration
Drug Testing and Analysis – May 16, 2020
Summary
Oral administration of 1P-LSD, a non-controlled psychedelic, results in nearly 100% bioavailability of LSD in the body, confirming its role as a prodrug. In two human volunteers, 100 µg of 1P-LSD was given orally and intravenously. Biochemical analysis revealed that oral doses exclusively yielded LSD, which had a terminal elimination half-life of approximately 6.4 hours. This pharmacology suggests 1P-LSD converts entirely to LSD, influencing neurotransmitter receptors and behavior. Subjective effects were comparable to LSD, with 5D-ASC scores higher after oral administration, offering insights for medicine and drug studies.
Abstract
Abstract 1‐Propanoyl‐lysergic acid diethylamide (1P‐LSD) appeared as a non‐controlled alternative to LSD a few years ago. Although evidence is begi...

Nothing Ventured, Nothing Gained: Regulations Cripple Potentially Life-Saving Research of Illicit Substances
ACS Chemical Neuroscience – May 12, 2020
Summary
Regulations designed to prevent harm from substances like Psilocybin and Lysergic acid diethylamide severely cripple scientific progress. These rules make it nearly impossible to acquire illicit hallucinogens for vital research, achieving nothing but hindering potential life-saving discoveries. Reclassifying these compounds would unlock critical advancements in Pharmacology, impacting fields from Psychedelics and Drug Studies to Cannabis and Cannabinoid Research and even Forensic Toxicology and Drug Analysis. This regulatory business currently stifles crucial scientific inquiry.
Abstract
Modern day research, in an attempt to determine the potential therapeutic and adverse effects of illicit substances, is a growing field, but one th...
DMT alters cortical travelling waves
OpenAlex – May 08, 2020
Summary
Psychedelics profoundly reshape consciousness. N,N-Dimethyltryptamine (DMT), a serotonergic compound, robustly alters brain activity, revealing patterns akin to visual stimulation. Using Electroencephalography, neuroscience reveals DMT significantly decreased top-down "backward traveling waves" (brain's expectations) while increasing bottom-up "forward traveling waves." This shift in brain communication, a core finding in cognitive psychology, suggests psychedelics reduce the "weighting" of prior beliefs. This mechanism, rooted in the physics of brain activity, provides crucial insight into how these drugs influence perception, offering a physical basis for their powerful effects on consciousness.
Abstract
Abstract Psychedelic drugs are potent modulators of conscious states and therefore powerful tools for investigating their neurobiology. N,N, Dimeth...
Investigation of the 2,5-Dimethoxy Motif in Phenethylamine Serotonin 2A Receptor Agonists.
ACS chemical neuroscience – May 06, 2020
Summary
A specific chemical pattern on certain phenethylamine compounds has long been believed crucial for activating the serotonin 2a receptor. New research reveals that while removing key chemical groups from these agonists causes only a modest drop in lab-tested potency, it significantly reduces their in-body effects. This refines our understanding of the structure−activity relationship, showing this particular motif is vital for the in vivo action of these phenethylamine agonists.
Abstract
The 2,5-dimethoxyphenethylamine (2,5-PEA) scaffold is recognized as a motif conferring potent agonist activity at the serotonin 2A receptor (5-HT2A...
Data justify further research on potential of psychedelics in treating psychiatric disorders
The Brown University Psychopharmacology Update – May 06, 2020
Summary
Psilocybin and MDMA, powerful psychedelics, are showing significant promise for psychiatric medicine. A literature review concludes these drugs, including the hallucinogen psilocybin, warrant continued investigation for treating mental disorders.

Generative modelling of the thalamo-cortical circuit mechanisms underlying the neurophysiological effects of ketamine
bioRxiv Preprint Server – May 05, 2020
Summary
Ketamine dramatically shifts brain activity. To understand how, a sophisticated computer model of brain circuits was developed. This model successfully replicated ketamine's effect on brain waves – boosting high-frequency activity while reducing low-frequency patterns. The key finding: ketamine primarily enhances specific neural connections involving chemicals like NMDA, AMPA, and GABA-A, rather than altering receptor response times. This offers powerful computational insight into how ketamine modifies brain function.
Abstract
Cortical recordings of task-induced oscillations following subanaesthetic ketamine administration demonstrate alterations in amplitude, including i...
