Summary
Psychedelics reliably shift personal values, often fostering self-transcendence. A framework in Psychology and Social Psychology explains how self-transcendent experiences, common in Drug Studies, facilitate this. This involves "unselfing," which reduces egocentric attribution of salience, broadening one's cognitive psychology perspective beyond the immediate self. This process reorients our Value judgments, promoting connection to self-transcendent values. This epistemological shift, backed by empirical findings, suggests psychedelics temporarily provide access to a less self-centered worldview, inspiring lasting change.
Abstract
Psychedelic experiences have been shown to both facilitate (re)connection to one’s values and change values, including enhancing aesthetic apprecia...
Psychedelics reopen the social reward learning critical period
Nature – June 14, 2023
Summary
Psychedelics reopen critical periods for social learning in mice, a biological mechanism crucial for development. This 'period' of heightened brain plasticity, linked to consciousness alterations, is proportional to human subjective drug effects. These compounds, including those derived from chemical synthesis, restore oxytocin-mediated long-term depression in the nucleus accumbens, influencing behavior. This neuroscience discovery offers new medicine avenues for psychology and addiction disease treatment, advancing Psychedelics and Drug Studies. Psilocybin and similar compounds show promise.

Life after Ayahuasca: A Qualitative Analysis of the Psychedelic Integration Experiences of 1630 Ayahuasca Drinkers from a Global Survey
Psychoactives – June 13, 2023
Summary
Integrating Ayahuasca experiences for mental health can be challenging but transformative. A qualitative research survey of 1630 Ayahuasca drinkers (50.4% male) used thematic analysis to explore post-experience integration. Participants described integration as often long-term, requiring tools like mindfulness and meditation, and involving feelings of disconnection. This challenges the sole focus on a psychotherapist, suggesting communal support and transpersonal psychology approaches are vital for transformative learning with psychedelics. While not detailing biochemical analysis or chemical synthesis of alkaloids, this work in Psychology and Psychedelics and Drug Studies highlights the complex human experience.
Abstract
Ayahuasca is an Amazonian psychoactive plant medicine being explored for its potential therapeutic uses in Western contexts. Preliminary studies li...

A regulatory framework review of Schedule I psychedelics in the United States
JACCP JOURNAL OF THE AMERICAN COLLEGE OF CLINICAL PHARMACY – June 12, 2023
Summary
Psilocybin and MDMA, powerful hallucinogens, are paradoxically designated "Breakthrough Therapy" by the Food and Drug Administration, even as federal Legislation from 1970 classifies them as Schedule I substances. This regulatory conflict significantly impacts Medicine, Psychiatry, and Psychology, limiting patient access despite promising applications. Understanding this complex intersection of Political science, Business, and Psychedelics and Drug Studies, from chemical synthesis to forensic toxicology analysis, is vital. Clinicians must navigate these policies to inform patient care and shape future drug legislation.
Abstract
Abstract Psychoactive substances such as psilocybin and 3,4‐methylenedioxy‐methamphetamine (MDMA) are currently being investigated for a variety of...
