Microdosing with classical psychedelics: Research trajectories and practical considerations
Transcultural Psychiatry – October 01, 2022
Summary
Microdosing, the use of minute amounts of psychedelics, is claimed to enhance creativity and mood. Psychology explores how substances like psilocybin, lysergic acid diethylamide, and mescaline—compounds often from chemical synthesis or natural alkaloids—influence consciousness and perception. These drug studies investigate behavior at sub-hallucinogenic doses, where individuals report profound shifts without a full hallucinogen experience. Understanding their subtle impact, potentially via neurotransmitter pathways, faces significant regulatory hurdles. The field aims to distinguish genuine effects from expectation.

Ethical Issues Regarding Nonsubjective Psychedelics as Standard of Care
Cambridge Quarterly of Healthcare Ethics – October 01, 2022
Summary
A compelling finding in Psychology reveals psychedelics' therapeutic benefits largely stem from their profound subjective experiences. Although Chemical synthesis is creating "nonsubjective" compounds for individuals with specific mental illnesses, a critical ethical argument emerges for psychotherapists. These altered substances should be reserved for cases where subjective effects are truly contraindicated. For most patients, classic psychedelics, offering positive and meaningful experiences, should remain the default. Withholding these beneficial subjective journeys from the majority raises significant ethical questions relevant to Social psychology and Psychedelics and Drug Studies.

Neurovascular Uncoupling: Multimodal Imaging Delineates the Acute Effects of 3,4-Methylenedioxymethamphetamine
Journal of Nuclear Medicine – September 29, 2022
Summary
MDMA's acute effects on the brain are more complex than previously thought. In rats, this hallucinogen stimulates neuronal activity in limbic areas, key for emotional processing, increasing glucose metabolism. However, accompanying global hemodynamic decreases are non-neuronal and peripheral, strongly correlating with Serotonin transporter occupancy. Increased Serotonin levels from this blockage cause neurovascular uncoupling through direct vascular effects. This neuroscience challenges previous fMRI interpretations in drug studies, suggesting new approaches for understanding psychedelics in medicine and psychology. Pharmacology must consider these complex haemodynamic responses.

Sex dependence of opioid-mediated responses to subanesthetic ketamine
bioRxiv Preprint Server – September 06, 2022
Summary
A surprising finding reveals how a rapid-acting antidepressant works differently in males and females. Research into ketamine's ability to quickly reduce depression symptoms found its beneficial brain effects, linked to mood and reward, depend on opioid signaling in males. This crucial opioid connection was absent in females and reversed in males without male hormones.

Microdosing psilocybin for chronic pain: a case series
Pain – September 05, 2022
Summary
Three individuals suffering from chronic pain found robust relief using low-dose psilocybin, a naturally occurring alkaloid. This case series highlights how these patients, for whom traditional medicine offered little solace, achieved significant pain reduction and decreased reliance on other drugs. The effects occurred without a psychedelic experience and with minimal side effects. For all three, combining psilocybin with exercise magnified relief, with one patient experiencing increased benefit from repeated dosing. This suggests long-term potential in Complementary and Alternative Medicine Studies for chronic pain management.

Psychological effects and subjective experiences of ayahuasca rituals in participants of two neoshamanic centers of Uruguay
Journal of Psychedelic Studies – September 02, 2022
Summary
Ayahuasca ceremonies reveal striking psychological effects, with significant differences observed between two neoshamanic groups in Uruguay. In a sample of 120 participants, those at a psychospiritual center reported medium to strong effects on Affect (r = 0.47), Cognition (r = 0.36), and Perception (r = 0.36) compared to a substance use treatment center. Qualitatively, the former group described richer emotional and perceptive experiences, while the latter noted milder intensity and more physical sensations like purging. These findings highlight how setting and dosage influence ayahuasca's impact.

Abstract Background Ayahuasca's psychological and subjective effects were compared in rituals of two neoshamanic groups in Uruguay. Aims Compare, d...
Tripping to Cope: Coping Strategies and Use of Hallucinogens during the COVID-19 Pandemic in Three Cultural Contexts
Psychoactives – September 02, 2022
Summary
During the COVID-19 pandemic, individuals using hallucinogens displayed an adaptive coping psychology, scoring higher on problem-focused engagement and disengagement coping, and lower on wishful thinking. A psychometric survey of 2971 subjects across three cultures explored how coping strategies relate to pandemic distress. While coping was strongly tied to overall mental health, its association with hallucinogen use was marginal. These insights, relevant to clinical and developmental psychology and COVID-19 and Mental Health, suggest psychedelics might foster cognitive processes that aid in managing stressors, potentially reducing anxiety and depression. This could inform treatment.
Abstract
The COVID-19 pandemic has made evident the need to develop effective strategies to cushion the psychological consequences of social catastrophes. P...
To treat or not to treat? High-potency benzodiazepine use in a case of comorbid hallucinogen persisting perception disorder and alcohol use disorder.
Experimental and Clinical Psychopharmacology – September 01, 2022
Summary
Visual hallucinations can persist for over 20 years after Lysergic acid diethylamide (LSD) use, a key finding in Psychology and Psychiatry. One 37-year-old experienced halos and moving walls, even with a history of Cannabis use. These severe perception disturbances, characteristic of a Hallucinogen persisting perception disorder, resolved with Clonazepam, a Benzodiazepine. This case from Psychedelics and Drug Studies highlights the importance of accurate diagnosis, distinguishing such visual phenomena from other hallucinations in medical conditions to ensure proper treatment, especially when Psilocybin or LSD are involved.
Abstract
Hallucinogen persisting perception disorder (HPPD) is characterized by visual disturbances that resemble psychedelic intoxication and linger after ...
Effects of psilocybin versus escitalopram on rumination and thought suppression in depression
BJPsych Open – September 01, 2022
Summary
Psilocybin, a potent hallucinogen, uniquely reduces maladaptive rumination and thought suppression in individuals with major depression. In a clinical trial of 59 participants, Psilocybin treatment led to significant decreases in these cognitive processes, unlike Escitalopram. Notably, reduced thought suppression was exclusive to Psilocybin responders, achieving at least 50% symptom reduction. This offers new insights for psychiatry, internal medicine, and clinical psychology into treatment of major depression, impacting psychometrics of cognition and anxiety management through novel psychedelics and drug studies.
Abstract
Background Major depressive disorder is often associated with maladaptive coping strategies, including rumination and thought suppression. Aims To ...
Intoxication by 3-MeO-PCP and O-desmethyltramadol: an unusual NPS mix.
International journal of legal medicine – September 01, 2022
Summary
A unique intoxication case revealed a man's death from a potent combination of 3-MeO-PCP and O-desmethyl tramadol. Forensic toxicology analysis identified five different compounds, with these two specifically identified and quantified in blood samples, confirming their role in the fatal event. This unusual mix underscores the critical need for thorough scene investigations and broad-spectrum analytical methods to understand diverse new psychoactive substance intoxications. Such cases provide vital insights for public health.

Past-year hallucinogen use in relation to psychological distress, depression, and suicidality among US adults.
Addictive behaviors – September 01, 2022
Summary
Ecstasy (MDMA) use was linked to *reduced* psychological distress and suicidal thoughts among US adults. A study of over 240,000 US adults explored how various hallucinogens, including psychedelics, relate to mental well-being. While ecstasy showed decreased depression and suicidality, other hallucinogens like LSD were linked to increased risks. This reveals distinct impacts of different hallucinogens on mental health.
Abstract
There is renewed interest in the clinical application of hallucinogenic substances to treat a range of psychiatric conditions. However, there is mi...

Psychedelics in the Treatment of Substance Use Disorders
Psychiatric Annals – September 01, 2022
Summary
Psychedelics like psilocybin and lysergic acid diethylamide show significant promise for treating addiction, including alcohol, opioid, and tobacco use disorders. Growing evidence from observational studies and clinical trials suggests these hallucinogens, influencing neurotransmitter receptors, may facilitate profound psychological shifts. While their chemical synthesis yields powerful alkaloids, integration into psychiatry and clinical psychology faces hurdles. Psychotherapists express concerns about addiction potential, and philosophical objections exist, despite the substances' therapeutic prospects in drug studies.
