Receptor binding profiles and behavioral effects of psilocybin analogs
The FASEB Journal – May 01, 2022
Summary
A compelling finding reveals psilacetin, a synthetic psilocybin analog, acts as a potent hallucinogen with potential intrinsic psychedelic activity, not merely as a prodrug. *In vivo* studies in male mice, using doses from 0.03 to 3 mg/kg, showed psilocin most potent for head twitch responses, followed by psilacetin and psilocybin. This pharmacology suggests psilacetin converts to psilocin, yet its direct agonist action at 5-HT2A receptors (nM affinities) is significant. An antagonist blocked these effects, clarifying 5-HT2A receptor influence on behavior and advancing understanding of these alkaloids' stereochemistry.

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.

Entactogens: How the Name for a Novel Class of Psychoactive Agents Originated
Frontiers in Psychiatry – March 25, 2022
Summary
MDMA, a popular psychoactive substance, is structurally similar to hallucinogens like MDA but exhibits unique properties. In studies, MDMA retains about 80% of MDA's potency while promoting social behavior and introspection rather than hallucinations. Notably, the dextro isomer of MDMA is more active than its levo counterpart. Altering its structure by extending the alpha-methyl to an alpha-ethyl group led to N-Methyl-1-(1,3-benzodioxol-5-yl)-2-butanamine (MBDB), which maintained significant psychoactivity. This highlights MDMA's distinct pharmacology, earning it the classification "entactogen."
Abstract
At first glance, it appears there is little difference between the molecular structures of methylenedioxymethamphetamine (MDMA), which has an N -me...

Psilocybin-Assisted Compassion Focused Therapy for Depression
Frontiers in Psychology – March 25, 2022
Summary
Psilocybin, a potent hallucinogen, demonstrates significant efficacy, with studies showing it reduces depressive symptoms by over 50% for many patients. To enhance these benefits, a new clinical psychology protocol integrates Compassion Focused Therapy (CFT) into psilocybin-assisted psychotherapy. This framework provides psychotherapists with specific guidance, emphasizing compassion practices and mindfulness throughout the typical three-phase treatment. The aim is to deepen psychological insights during therapy sessions, potentially improving outcomes in psychiatry and advancing psychotherapy techniques within psychedelics and drug studies, and complementary medicine applications.

Differential contributions of serotonergic and dopaminergic functional connectivity to the phenomenology of LSD
Psychopharmacology – March 24, 2022
Summary
LSD profoundly reshapes brain activity, influencing subjective experience through more than just the 5-HT2A receptor. In a Neuroscience analysis of 15 individuals, this psychedelic drug significantly altered brain connectivity associated with various Serotonergic (5-HT1a, 5-HT1b, 5-HT2A) and Dopaminergic (D1, D2) receptors. These changes linked to distinct psychological effects: Serotonin receptors influenced perception and selfhood, while Dopamine receptors impacted cognition. This Biochemical Analysis highlights the complex neurotransmitter receptor influence on behavior, suggesting LSD acts as an agonist across multiple 5-HT and Dopamine receptors.
Abstract
Abstract Rationale LSD is the prototypical psychedelic. Despite a clear central role of the 5HT 2a receptor in its mechanism of action, the contrib...

Race, Ethnic, and Sex Differences in Prevalence of and Trends in Hallucinogen Consumption Among Lifetime Users in the United States Between 2015 and 2019
Frontiers in Epidemiology – March 23, 2022
Summary
Asian females exhibit the highest past-year hallucinogen use (35.06%), over twice that of White males/females. An analysis of 41,060 lifetime users reveals significant demography in psychedelic patterns. Pacific Islander males, a distinct ethnic group, had peak mescaline use (28.27%). Black, Asian, and Multiracial individuals had greater odds (1.20–2.06) of recent hallucinogen use than White people. Females generally had lower odds, except for MDMA. These insights into psilocybin and other hallucinogen use are vital for understanding drug studies and potential medicine applications across diverse populations.
Abstract
Background The current study is one of the first to examine race, ethnic, and sex differences in the prevalence of and trends in hallucinogen use a...
Ministry of the Mushroom
International Journal for the Study of New Religions – March 23, 2022
Summary
Beyond clinical applications, a compelling trend shows psilocybin mushroom churches emerging, offering unique spiritual pathways. These communities foster "sacred sensemaking," interpreting the hallucinogen psilocybin as a divine sacrament through ritual practices. This sociological shift contrasts with traditional Christian ministry, suggesting a distinct psychological approach to spiritual exploration. It expands psychedelics and drug studies beyond chemical synthesis, hinting at diverse academic research themes, from the aesthetics of ritual to the psychoanalytic depth of personal transformation.

Recently there has been a surge of renewed interest in the psychedelic compound psilocybin. In particular, psilocybin is being studied in clinical ...
How Important Is a Guide Who Has Taken Psilocybin in Psilocybin-Assisted Therapy for Depression?
Journal of Psychoactive Drugs – March 23, 2022
Summary
Potential clients for Psilocybin-Assisted Therapy (PAT) for depression strongly prefer a psychotherapist who has personally experienced the hallucinogen. Over 800 individuals with depressive symptoms rated a guide's psilocybin use as highly important, exceeding a "somewhat important" benchmark of 50 on a 100-point scale.
