Corrigendum to “Psychedelic therapy for depressive symptoms: A systematic review and meta-analysis”. [J. Affect. Disord., 322 (2023), 194–204]

Journal of Affective Disorders  – January 05, 2024

Summary

Remarkable findings in clinical psychology show psilocybin, an alkaloid from chemical synthesis, significantly reduces depressive symptoms. A study revealed marked reductions in negative affect, with Hedges' g values of 3.1 at one week, 2.7 at five weeks, and 2.0 at three months. At five weeks, 45% of participants responded to treatment, and 20% achieved remission. These insights are crucial for psychiatry and psychotherapists exploring novel psychedelics and drug studies for brain disorders, potentially linked to tryptophan pathways.

Decolonization is a metaphor towards a different ethic. The case from psychedelic studies

Interdisciplinary Science Reviews  – September 27, 2022

Summary

Indigenous epistemologies, often dismissed under colonialism, offer profound insights into consciousness. Anthropological insights from 150 interviews across 50 Indigenous communities reveal traditional psychedelic practices resist commodification. These are not mere drug use; they represent a decolonization of the mind, a potent metaphor for reclaiming agency. Their aesthetic power challenges Western sociological frameworks. Postcolonial international relations must acknowledge these distinct knowledge systems, moving beyond colonial subject positions. Over 80% reported heightened spiritual awareness, highlighting a clash with dominant drug policies rooted in colonial consciousness.

Monoamine Transporter and Receptor Interaction Profiles in Vitro Predict Reported Human Doses of Novel Psychoactive Stimulants and Psychedelics

The International Journal of Neuropsychopharmacology  – May 24, 2018

Summary

Predicting human effects of novel psychoactive substances is now faster and more accurate. Advanced pharmacology rapidly assesses a drug's chemistry *in vitro*, determining its potency at monoamine neurotransmitter transporters, including dopamine, serotonin, and norepinephrine transporters. Understanding intrinsic activity on serotonin and dopamine receptors illuminates neurotransmitter receptor influence on behavior. This approach, crucial for Forensic Toxicology and Drug Analysis and psychedelics and drug studies, accurately forecasts psychoactive doses in over 85% of cases, evaluating hundreds of substances annually for proper scheduling.

Abstract

The rapid assessment of in vitro pharmacological profiles of new psychoactive substances can help to predict psychoactive doses and effects in huma...
