The Viability of Microdosing Psychedelics as a Strategy to Enhance Cognition and Well-being – An Early Review

May 2, 2020 / Anxiety Disorders / PTSD, Depressive Disorders, LSD, Mushrooms / Psilocybin, Papers, Psychology, Publications / By /

Abstract

Psychedelic substances are currently experiencing a renaissance in interest for both therapeutic as well as recreational applications. It has been proposed that microdosing, i.e., ingesting sub-perceptual doses of a psychedelic, could confer some of the benefits of these substances to users while minimizing the risks associated with full-dose use. This review aimed to summarize and examine the extant literature on psychedelic microdosing. Exploratory evidence published to date indicates a variety of benefits reported by microdosers including improvements in mood, focus, and creativity, with some null reports, and a minority of people reporting selective negative consequences such as increased anxiety and physiological discomfort. Methodological limitations of current evidence, however, make definitive conclusions hard to draw. Recommendations for future research are given.

Abstract

Objective: The authors provide an evidenced-based summary of the literature on the clinical application of psychedelic drugs in psychiatric disorders.
Methods: Searches of PubMed and PsycINFO via Ovid were conducted for articles in English, in peer-reviewed journals, reporting on “psilocybin,” “lysergic acid diethylamide,” “LSD,” “ayahuasca,” “3,4-methylenedioxymethamphetamine,” and “MDMA,” in human subjects, published between 2007 and July 1, 2019. A total of 1,603 articles were identified and screened. Articles that did not contain the terms “clinical trial,” “therapy,” or “imaging” in the title or abstract were filtered out. The 161 remaining articles were reviewed by two or more authors. The authors identified 14 articles reporting on well-designed clinical trials investigating the efficacy of lysergic acid diethylamide (LSD), 3,4-methylenedioxymethamphetamine (MDMA), psilocybin, and ayahuasca for the treatment of mood and anxiety disorders, trauma and stress-related disorders, and substance-related and addictive disorders as well as in end-of-life care.
Results: The most significant database exists for MDMA and psilocybin, which have been designated by the U.S. Food and Drug Administration (FDA) as “breakthrough therapies” for posttraumatic stress disorder (PTSD) and treatment-resistant depression, respectively. The research on LSD and ayahuasca is observational, but available evidence suggests that these agents may have therapeutic effects in specific psychiatric disorders.
Conclusions: Randomized clinical trials support the efficacy of MDMA in the treatment of PTSD and psilocybin in the treatment of depression and cancer-related anxiety. The research to support the use of LSD and ayahuasca in the treatment of psychiatric disorders is preliminary, although promising. Overall, the database is insufficient for FDA approval of any psychedelic compound for routine clinical use in psychiatric disorders at this time, but continued research on the efficacy of psychedelics for the treatment of psychiatric disorders is warranted.

Psychedelic Psychiatry’s Brave New World

April 2, 2020 / LSD, MDMA, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , ,

Abstract

After a legally mandated, decades-long global arrest of research on psychedelic drugs, investigation of psychedelics in the context of psychiatric disorders is yielding exciting results. Outcomes of neuroscience and clinical research into 5-Hydroxytryptamine 2A (5-HT2A) receptor agonists, such as psilocybin, show promise for addressing a range of serious disorders, including depression and addiction.

Experience of Music Used With Psychedelic Therapy: A Rapid Review and Implications.

March 30, 2020 / Ayahuasca, LSD, MDMA, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , , , ,

Abstract

Bonny Method of Guided Imagery and Music emerged following discontinuation of psychedelic therapy research in the early 1970s, but psychedelic therapy research has since revived. Music remains a vital component. This study examined participants’ experiences of music in psychedelic therapy research. A rapid review of qualitative and quantitative journal articles in four major databases was conducted in February to April, 2019, using the terms hallucinogens, psychedelic, “lysergic acid diethylamide,” psilocybin, ayahuasca, music, and/or “music therapy.” Of 406 articles retrieved, 10 were included (n = 180; 18-69 years old). Participants had varied backgrounds. Music was widely considered integral for meaningful emotional and imagery experiences and self-exploration during psychedelic therapy. Music transformed through its elicitation of anthropomorphic, transportive, synesthetic, and material sensations. Music could convey love, carry listeners to other realms, be something to “hold,” inspire, and elicit a deep sense of embodied transformation. Therapeutic influence was especially evident in music’s dichotomous elicitations: Music could simultaneously anchor and propel. Participant openness to music and provision of participant-centered music were associated with optimal immediate and longer-term outcomes. Many studies reported scarce details about the music used and incidental findings of music experienced. Further understanding of participants’ idiosyncratic and shared responses to music during drug therapy phases will inform optimal development of flexible music protocols which enhance psychedelic therapy. Music therapists could be involved in the psychedelic therapy research renaissance through assisting with research to optimize music-based protocols used. If psychedelics become approved medicines, music therapists may be involved in offering psychedelic therapy as part of therapeutic teams.

Abstract

There are few medications with demonstrated efficacy for the treatment of posttraumatic stress disorder (PTSD). Treatment guidelines have unequivocally designated psychotherapy as a first line treatment for PTSD. Yet, even after psychotherapy, PTSD often remains a chronic illness, with high rates of psychiatric and medical comorbidity. Meanwhile, the search and development of drugs with new mechanisms of action has stalled. Therefore, there is an urgent need to explore not just novel compounds, but novel approaches for the treatment of PTSD. A promising new approach involves the use of psychedelic drugs. Within the past few years, two psychedelics have received breakthrough designations for psychiatric indications from the US Food and Drug Administration, and several psychedelics are currently being investigated for the treatment of PTSD. This review discusses four types of compounds: 3,4-methylenedioxymethamphetamine (MDMA), ketamine, classical psychedelics (e.g. psilocybin and LSD) and cannabinoids. We describe the therapeutic rationale, the setting in which they are being administered, and their current state of evidence in the treatment of PTSD. Each compound provides unique qualities for the treatment of PTSD, from their use to rapidly target symptoms, to their use as adjuncts to facilitate psychotherapeutic treatments. Several questions are formulated that outline an agenda for future research.

The Psychedelic Renaissance and Its Forensic Implications

March 9, 2020 / Humanities & Art, LSD, Papers, Psychology, Publications / By /

Abstract

Recent years have seen a renaissance of research into the use of psychedelic compounds to address various psychiatric conditions. The study of these substances went dormant in 1970 when the United States government passed the Controlled Substances Act, which categorized lysergic acid diethylamide, commonly known as LSD or acid, as a Schedule I drug. The rise of psychedelics in research settings raises questions regarding their risks outside of clinical trials. The available data on the impact of psychedelic use on interpersonal violence and other criminal behavior remain scant. Although Timothy Leary’s work of the 1960s failed to clearly demonstrate a reduction in criminal recidivism with psychedelic-assisted psychotherapy, recent studies suggest that the use of psychedelics may reduce individuals’ risk of interpersonal violence. Forensic psychiatrists should be aware of this research, as well as the role that psychedelics may play in various forensic assessments. This article summarizes basic information that the forensic practitioner should know about psychedelic substances, including their various effects and proposed mechanism of action; describes historical and recent research into psychedelics and criminal behavior; and offers evaluators a practical means by which to assess individuals’ psychedelic use in forensic contexts.

Natural Psychoplastogens As Antidepressant Agents

March 5, 2020 / Ayahuasca, Depressive Disorders, DMT, LSD, MDMA, Mescaline / Cacti, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / ,

Abstract

Increasing prevalence and burden of major depressive disorder presents an unavoidable problem for psychiatry. Existing antidepressants exert their effect only after several weeks of continuous treatment. In addition, their serious side effects and ineffectiveness in one-third of patients call for urgent action. Recent advances have given rise to the concept of psychoplastogens. These compounds are capable of fast structural and functional rearrangement of neural networks by targeting mechanisms previously implicated in the development of depression. Furthermore, evidence shows that they exert a potent acute and long-term positive effects, reaching beyond the treatment of psychiatric diseases. Several of them are naturally occurring compounds, such as psilocybin, N,N-dimethyltryptamine, and 7,8-dihydroxyflavone. Their pharmacology and effects in animal and human studies were discussed in this article.

Psychedelics and Dying Care: A Historical Look at the Relationship Between Psychedelics and Palliative Care

March 1, 2020 / Anxiety Disorders / PTSD, LSD, Papers, Psychology, Publications / By /

Abstract

This article examines the historical relationship between psychedelics and palliative care. Historians have contributed to a growing field of studies about how psychedelics have been used in the past, but much of that scholarship focused on interrogating questions of legitimacy or proving that psychedelics had therapeutic potential. Palliative care had not yet developed as medical sub-specialty, more often leaving dying care on the margins of modern, pharmaceutical-based treatments. As psychedelic researchers in the 1950s began exploring different applications for psychoactive substances such as LSD and mescaline, however, dying care came into clearer focus as a potential avenue for psychedelics. Before that application gained momentum in clinical or philosophical discussions, psychedelics were criminalized and some of those early discussions were lost. This article looks back at historical discussions about LSD’s potential for easing the anxiety associated with dying, and considers how those early conversations might offer insights into today’s more articulated discussions about psychedelics in palliative care.

Microdosing psychedelics: Demographics, practices, and psychiatric comorbidities.

February 28, 2020 / LSD, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , , , , , ,

Abstract

RATIONALE:
Microdosing psychedelics – the practice of consuming small, sub-hallucinogenic doses of substances such as LSD or psilocybin – is gaining attention in popular media but remains poorly characterized. Contemporary studies of psychedelic microdosing have yet to report the basic psychiatric descriptors of psychedelic microdosers.
OBJECTIVES:
To examine the practices and demographics of a population of psychedelic microdosers – including their psychiatric diagnoses, prescription medications, and recreational substance use patterns – to develop a foundation on which to conduct future clinical research.
METHODS:
Participants (n = 909; Mage = 26.9, SD = 8.6; male = 83.2%; White/European = 79.1%) recruited primarily from the online forum Reddit completed an anonymous online survey. Respondents who reported using LSD, psilocybin, or both for microdosing were grouped and compared with non-microdosing respondents using exploratory odds ratio testing on demographic variables, rates of psychiatric diagnoses, and past-year recreational substance use.
RESULTS:
Of microdosers, most reported using LSD (59.3%; Mdose = 13 mcg, or 11.3% of one tab) or psilocybin (25.9%; Mdose = 0.3 g of dried psilocybin mushrooms) on a one-day-on, two-days-off schedule. Compared with non-microdosers, microdosers were significantly less likely to report a history of substance use disorders (SUDs; OR = 0.17 (95% CI: 0.05-0.56)) or anxiety disorders (OR = 0.61 (95% CI: 0.41-0.91)). Microdosers were also more likely to report recent recreational substance use compared with non-microdosers (OR = 5.2 (95% CI: 2.7-10.8)).
CONCLUSIONS:
Well-designed randomized controlled trials are needed to evaluate the safety and tolerability of this practice in clinical populations and to test claims about potential benefits.

A review of emerging therapeutic potential of psychedelic drugs in the treatment of psychiatric illnesses

January 30, 2020 / Anxiety Disorders / PTSD, Ayahuasca, Depressive Disorders, LSD, MDMA, Mushrooms / Psilocybin, Papers, Psychology, Psychotic Disorders, Publications, Substance Use Disorder / By / ,

Abstract

Though there was initial interest in the use of psychedelic drugs for psychiatric treatment, bad outcomes and subsequent passage of the Substance Act of 1970, which placed psychedelic drugs in the Schedule I category, significantly limited potential progress. More recently, however, there has been renewal in interest and promise of psychedelic research. The purpose of this review is to highlight contemporary human studies on the use of select psychedelic drugs, such as psilocybin, LSD, MDMA and ayahuasca, in the treatment of various psychiatric illnesses, including but not limited to treatment-resistant depression, post-traumatic stress disorder, end-of-life anxiety, and substance use disorders. The safety and efficacy as reported from human and animal studies will also be discussed. Accumulated research to date has suggested the potential for psychedelics to emerge as breakthrough therapies for psychiatric conditions refractory to conventional treatments. However, given the unique history and high potential for misuse with popular distribution, special care and considerations must be undertaken to safeguard their use as viable medical treatments rather than drugs of abuse.
