Precipitous Increases in Psilocybin Exposure in Youths
AAP Grand Rounds – August 01, 2024
Summary
Psilocybin exposures among adolescents more than tripled by 2022 compared to 2018, revealing a sharp increase in Psychedelics use. Examining 4,055 cases from 2013-2022, 58.5% of exposures involved adolescents, with 81.1% being intentional. Most adolescent cases (75.3%) required healthcare, and 47.1% experienced moderate effects. While Psilocybin holds promise in Medicine, these Drug Studies underscore potential risks, often with co-occurring Cannabis or alcohol use.

The Use of Ketamine for the Treatment of Anhedonia in Depression.
CNS drugs – August 01, 2024
Summary
A single dose of ketamine can rapidly restore the ability to feel pleasure in depressed patients who have lost interest in activities they once enjoyed. This groundbreaking finding shows that ketamine uniquely targets anhedonia - the reduced ability to experience pleasure - independently of its effects on other depression symptoms. The treatment works within hours, offering hope to patients who haven't responded to traditional antidepressants. Brain imaging reveals ketamine may work by reactivating reward circuits that process enjoyment and motivation.

Psilocybin Facilitates Fear Extinction: Importance of Dose, Context, and Serotonin Receptors
ACS Chemical Neuroscience – August 01, 2024
Summary
The potent hallucinogen psilocybin significantly enhances fear extinction, a core process in psychology. In mice, this alkaloid boosted the reversal of fear conditioning across all tested doses when administered before exposure therapy; females responded to a narrower dose range. Neuroscience and pharmacology confirm psilocybin's long-term effects on extinction retention and suppressing fear renewal in a novel context. This depends critically on serotonin neurotransmitter receptor influence on behavior, specifically 5-HT2A receptors. Such psychedelics, compounds often derived via chemical synthesis, show strong potential for adjunctive studies.
Abstract
A variety of classic psychedelics and MDMA have been shown to enhance fear extinction in rodent models. This has translational significance because...

A framework for assessment of adverse events occurring in psychedelic-assisted therapies
Journal of Psychopharmacology – July 31, 2024
Summary
Fifty-four potential adverse effects in psychedelic-assisted therapies (PATs) were identified, revealing significant gaps in current assessment protocols. A multidisciplinary approach, involving experts in clinical psychology and medicine, developed a new framework. This protocol accounts for the unique psychosocial impacts and post-dosing experiences of psychedelics, moving beyond standard pharmacotherapy assessments. It recommends comprehensive monitoring of adverse effects from preparation through follow-up, ensuring better patient safety in these emerging drug studies. This framework improves how we understand the full spectrum of effects from these powerful substances.

Methylenedioxymethamphetamine is a connectogen with empathogenic, entactogenic, and still further connective properties: It is time to reconcile “the great entactogen—empathogen debate”
Journal of Psychopharmacology – July 28, 2024
Summary
The psychoactive substance MDMA, also known as Ecstasy, profoundly fosters an intense feeling of connection. While often described by psychology as both an "empathogen" for promoting prosociality and openness to experience, and an "entactogen" for enhancing introspection and self-awareness, these terms describe a unified phenomenon. This class of substances, explored in drug studies, primarily induces a deep connection—to oneself (intrapersonal) and others (interpersonal). Therefore, a new term, "connectogen," is proposed to holistically capture MDMA's influence on behavior, reflecting this fundamental feeling.

Science on methylenedioxymethamphetamine (MDMA) and MDMA-like substances is faced with the unique situation that this class of psychoactive agents ...

Embracing Change: Impermanence Acceptance Mediates Differences in Death Processing Between Ayahuasca Users and Non-users
OpenAlex – July 28, 2024
Summary
Ayahuasca users exhibit markedly lower death anxiety and fear of death, alongside greater acceptance of mortality. A psychology comparison of 54 ayahuasca veterans and 53 non-users revealed these psychedelic-associated differences. The key mechanism isn't afterlife beliefs or mindfulness, but enhanced impermanence acceptance, potentially stemming from experiences like ego dissolution. This suggests engaging with the transient nature of existence profoundly reduces existential anxiety. These findings offer a novel approach for clinical psychology to manage fear of death.
Abstract

PTSD Treatment: An Inquiry into the Promising Potential of Psilocybin
Journal of Advances in Medicine and Medical Research – July 24, 2024
Summary
Psilocybin, a potent hallucinogen, holds significant promise within clinical psychology and psychiatry for treating Post-Traumatic Stress Disorder (PTSD). This serotonergic compound, explored in diverse academic research themes, appears to alleviate dysphoria and anxiety by positively influencing mood regulation. Derived through chemical synthesis and alkaloids, psilocybin enhances introspection and reduces amygdala reactivity, pivotal for fear extinction. As a psychedelic, it offers a novel adjunct to psychotherapist-led interventions, directly addressing symptoms and potentially improving patient outcomes.

Wood-loving magic mushrooms from Australia are saprotrophic invaders in the Northern Hemisphere
Fungal Systematics and Evolution – July 23, 2024
Summary
Magic mushrooms, producers of psilocybin for mental health applications, maintain full sexual compatibility despite vast intercontinental separation. Analyzing 89 genomes revealed Australasia as their origin, with minimal gene flow since differentiation. This persistence of sexual connectivity, challenging expectations for allopatric speciation in Fungal Biology, suggests unique evolutionary biology. Psilocybin genes exhibit high allelic diversity. Their global Ecology, facilitated by woodchip movement, underscores fascinating aspects of fungal biology and gene flow, relevant to Psychedelics and Drug Studies.

Hippocampal PACAP signaling activation triggers a rapid antidepressant response.
Military Medical Research – July 23, 2024
Summary
A brain protein called PACAP could hold the key to faster-acting depression treatments. When researchers activated this protein in the hippocampus, it produced rapid antidepressant effects similar to ketamine. Using advanced optogenetic techniques and behavioral tests like novelty suppressed feeding, they found that PACAP levels drop during depression but increase with treatment. This discovery points to new possibilities for developing quick-acting antidepressants.

While both treatments reduced depressive symptoms, ketamine demonstrated good tolerability with only temporary side effects. The treatment's efficacy was tracked for a month, showing sustained response in many participants.

Studies have confirmed the rapid antidepressant action of ketamine in depressive episodes. Nevertheless, a standardized procedure for the delivery ...
Psychedelic trip sitting, dosages and intensities: Supplementing clinical studies with anecdotal reports
Journal of Psychedelic Studies – July 17, 2024
Summary
Users of 5-MeO-DMT, a potent hallucinogen, strongly perceived a need for care. Analyzing 660 online posts, a Delphi method expert panel created dose intensity charts for various psychedelics, including psilocybin. While oral administration was common for lower doses, greater drug purity from chemical synthesis and alkaloids, and higher doses, correlated with a perceived need for support. This work, vital for Psychology and Psychedelics and Drug Studies, informs medicine, guiding future biochemical analysis of substances like mescaline.

Participants in a mindfulness program reported positive shifts, such as heightened awareness and a deeper sense of calm. Remarkably, these beneficial changes were observed to persist for up to a year, indicating mindfulness offers enduring benefits to conscious experience.
