The influence of therapists’ first-hand experience with psychedelics on psychedelic-assisted psychotherapy research and therapist training

August 22, 2018 / MDMA, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / ,

Abstract

Clinical research on psychedelic-assisted psychotherapy is rapidly advancing in the USA, with two drugs, psilocybin and MDMA, progressing through a structure of FDA-approved trials on a trajectory toward Drug Enforcement Agency rescheduling for therapeutic use. Researcher’s and clinician’s personal use of psychedelics was cited as a potential confound in psychedelic research studies conducted in the 1950s and 1960s, a concern which contributed to the cessation of this research for some 20 years. Currently, there is no empirical research on personal use of psychedelics by current academic researchers and clinicians; its influence is undocumented, unknown, and undertheorized. This paper explores the history of personal use of psychedelics by clinicians and researchers, the potential impact of personal use on psychedelic-assisted psychotherapy and research, and the rationale for opening an academic discussion and program of research to investigate the role of personal use. We propose that there are factors unique to psychedelic-assisted therapy such that training for it cannot neatly fit into the framework of modern psychopharmacology training, nor be fully analogous to psychotherapy training in contemporary psychological and psychiatric settings. We argue that scientific exploration of the influence of therapists’ first-hand experience of psychedelics on psychedelic-assisted therapy outcomes is feasible, timely, and necessary for the future of clinical research.

Legitimate Medicine in the Age of Consumerism

August 21, 2018 / Anthropology & Sociology, Papers, Psychiatry & Medicine, Psychology, Publications / By /

Abstract

From the opioid epidemic and medical marijuana to abortion restrictions and physician-assisted suicide, disputes over the proper uses of medicine loom large in American life. Nowhere is this conflict more apparent than in federal drug control policy, which is premised on a clear distinction between legitimate “medical” uses and illicit “abuse.” Yet the Controlled Substances Act defines neither of these foundational concepts. While it is tempting to imagine medicine’s scope is limited to treating or preventing disease – rendering nontherapeutic drug use “abuse” – in fact medical practice has always included interventions that are not aimed at healing. This trend has only accelerated as medical practice has become increasingly consumer-oriented. From Adderall to Xanax, patients now routinely seek prescriptions not to treat diagnosable illnesses, but to relieve stress, improve productivity, and otherwise enhance quality of life.

As physicians increasingly prescribe psychoactive drugs to help healthy people obtain desirable mental states, distinguishing legitimate drug use from recreational abuse becomes ever more difficult. Having failed to acknowledge this challenge, the DEA, courts, and scholars have not offered a principled way to make this distinction, rendering drug control policy increasingly incoherent. As a result, doctors face criminal prosecution without clear standards governing prescribing, potentially valuable interventions are arbitrarily barred from the market, and millions seek the benefits of drugs without professional medical guidance to mitigate their risks.

Rather than being limited to therapeutic aims, medicine is better understood as the application of a loosely-defined set of knowledge and interventions that the law entrusts to specific professionals, with accompanying duties to use these tools to benefit patients. Medical practice includes treating and preventing illnesses, but can also include enhancing social and cognitive functioning and promoting the well-being of people whose challenges do not rise to the level of disorders. Discarding a narrow conception of medicine does not require abandoning the enforcement of drug laws or the policing of doctors. But acknowledging the expansiveness of medicine’s domain does argue for clarifying the scope of physicians’ criminal liability and pursuing new strategies for harnessing drugs’ benefits while mitigating their risks.

DMT Models the Near-Death Experience

August 15, 2018 / DMT, Papers, Psychology, Publications / By / , , , , , ,

Abstract

Near-death experiences (NDEs) are complex subjective experiences, which have been previously associated with the psychedelic experience and more specifically with the experience induced by the potent serotonergic, N,N-Dimethyltryptamine (DMT). Potential similarities between both subjective states have been noted previously, including the subjective feeling of transcending one’s body and entering an alternative realm, perceiving and communicating with sentient ‘entities’ and themes related to death and dying. In this within-subjects placebo-controled study we aimed to test the similarities between the DMT state and NDEs, by administering DMT and placebo to 13 healthy participants, who then completed a validated and widely used measure of NDEs. Results revealed significant increases in phenomenological features associated with the NDE, following DMT administration compared to placebo. Also, we found significant relationships between the NDE scores and DMT-induced ego-dissolution and mystical-type experiences, as well as a significant association between NDE scores and baseline trait ‘absorption’ and delusional ideation measured at baseline. Furthermore, we found a significant overlap in nearly all of the NDE phenomenological features when comparing DMT-induced NDEs with a matched group of ‘actual’ NDE experiencers. These results reveal a striking similarity between these states that warrants further investigation.

Efficacy, tolerability, and safety of serotonergic psychedelics for the management of mood, anxiety, and substance-use disorders: a systematic review of systematic reviews

August 13, 2018 / Ayahuasca, Depressive Disorders, LSD, Mushrooms / Psilocybin, Neuroscience, Papers, Psychology, Publications / By / , , ,

Abstract

Mood, anxiety, and substance-use disorders are among the most prevalent psychiatric disorders in the population. Although several pharmacological treatments are available, they are not effective for a significant proportion of patients and are associated with several adverse reactions. Therefore, new treatments should be explored. Recent studies suggest that serotonergic hallucinogens/psychedelics including ayahuasca, psilocybin, and lysergic acid diethylamide (LSD) have anxiolytic, antidepressive, and antiaddictive effects. Areas Covered: A systematic review of systematic reviews assessing the efficacy, safety, and tolerability of serotonergic hallucinogens/psychedelic was performed using the PubMed data base until 11 April 2018. Systematic reviews with or without meta-analysis were analyzed, but only reviews that described at least one randomized controlled trial (RCT) were included. Expert Commentary: Psilocybin and LSD reduced anxiety and depression in cancer patients and symptoms of alcohol and tobacco dependence, and ayahuasca reduced depression symptoms in treatment-resistant depression. Although the results are promising, several studies were open label, and only few were RCTs, and most had small sample sizes and a short duration. Single or few doses of these drugs seem to be well tolerated, but long-term studies are lacking. New RCTs with bigger samples and longer duration are needed to replicate these findings.

Therapeutic use of classic psychedelics to treat cancer-related psychiatric distress

August 13, 2018 / Anxiety Disorders / PTSD, Depressive Disorders, LSD, Mushrooms / Psilocybin, Papers, Psychiatry & Medicine, Psychology, Publications / By /

Abstract

Cancer is highly prevalent and one of the leading causes of global morbidity and mortality. Psychological and existential suffering is common in cancer patients, associated with poor psychiatric and medical outcomes. Promising early-phase clinical research (1960s to early 1970s) suggested a therapeutic signal for serotoninergic psychedelics (e.g. psilocybin, LSD) in treating cancer-related psychiatric distress. After several decades of quiescence, research on psychedelic-assisted therapy to treat psychiatric disorders in cancer patients has resumed within the last 2 decades in the US and Europe. This review article is based on a systematic search of clinical trials from 1960–2018 researching the therapeutic use of psychedelic treatment in patients with serious or terminal illnesses and related psychiatric illness. The search found 10 eligible clinical trials, with a total of 445 participants, with the vast majority of the patients having advanced or terminal cancer diagnoses. Six open label trials, published between 1964 and 1980 (n = 341), suggested that psychedelic therapy (mostly with LSD) may improve cancer-related depression, anxiety, and fear of death. Four RCTs trials were published between 2011 and 2016 (n = 104), mostly with psilocybin treatment (n = 92), and demonstrated that psychedelic-assisted treatment can produce rapid, robust, and sustained improvements in cancer-related psychological and existential distress.

Sub-acute and long-term effects of ayahuasca on affect and cognitive thinking style and their association with ego dissolution

August 13, 2018 / Anxiety Disorders / PTSD, Ayahuasca, Depressive Disorders, Neuroscience, Papers, Psychology, Publications / By / , , , , , ,

Abstract

Rationale

Ayahuasca is a psychotropic plant tea from South America used for religious purposes by indigenous people of the Amazon. Increasing evidence indicates that ayahuasca may have therapeutic potential in the treatment of mental health disorders and can enhance mindfulness-related capacities. Most research so far has focused on acute and sub-acute effects of ayahuasca on mental health-related parameters and less on long-term effects.

Objectives

The present study aimed to assess sub-acute and long-term effects of ayahuasca on well-being and cognitive thinking style. The second objective was to assess whether sub-acute and long-term effects of ayahuasca depend on the degree of ego dissolution that was experienced after consumption of ayahuasca.

Results

Ayahuasca ceremony attendants (N = 57) in the Netherlands and Colombia were assessed before, the day after, and 4 weeks following the ritual. Relative to baseline, ratings of depression and stress significantly decreased after the ayahuasca ceremony and these changes persisted for 4 weeks. Likewise, convergent thinking improved post-ayahuasca ceremony up until the 4 weeks follow-up. Satisfaction with life and several aspects of mindfulness increased the day after the ceremony, but these changes failed to reach significance 4 weeks after. Changes in affect, satisfaction with life, and mindfulness were significantly correlated to the level of ego dissolution experienced during the ayahuasca ceremony and were unrelated to previous experience with ayahuasca.

Conclusion

It is concluded that ayahuasca produces sub-acute and long-term improvements in affect and cognitive thinking style in non-pathological users. These data highlight the therapeutic potential of ayahuasca in the treatment of mental health disorders, such as depression.

Psychedelics and psychotherapy in Canada: Humphry Osmond and Aldous Huxley.

August 1, 2018 / Papers, Psychology, Publications / By / ,

Abstract

The decade of the 1950s is well known among historians of psychiatry for the unprecedented shift toward psychopharmacological solutions to mental health problems. More psychiatric medications were introduced than ever before or since (Healy, 2002). While psychiatric researchers later credited these drugs, in part, for controlling psychotic, depressive, and anxious symptoms-and subsequently for emptying decaying psychiatric institutions throughout the Western world-psychiatrists also produced a number of other theories that relied on a more delicate and nuanced blending of psychotherapy and psychopharmacology. Canadian-based researchers were at the forefront of experiments combining mescaline, LSD, and psychoactive substances later described as “psychedelics.” From a relatively isolated setting on the Canadian prairies, in one of the most notorious mental hospitals in North America, this blending of traditions generated a unique approach. A close look at the correspondence between the psychiatrist Humphry Osmond and his friend, the writer Aldous Huxley, who shared interests in psychoactive substances and their effects on perception, and the stimulation of empathy, gives us an opportunity to explore how they developed their psychedelic approach to therapy in the 1950s. The combination of working in an isolated hospital, far from the main research powers in North America, produced a sense of regional incubation and required Osmond to look for collaborators well beyond his own field of psychiatry.

A Gratuitous Grace: The Influence of Religious Set and Intent on the Psychedelic Experience

July 27, 2018 / Papers, Psychology, Publications / By / ,

ABSTRACT

Psychedelic drugs, or entheogens, have been used for religious purposes among various cultures for thousands of years. Recently, these substances have caught the attention of Westerners for many reasons, including their propensity to induce mystical experiences. This study examined the relationship between religion and having mystical experiences. A total of 119 participants were drawn from psychedelic-related websites and asked to complete an anonymous online questionnaire containing items regarding history of psychedelic use, set and setting for psychedelic use, and a measure for mystical experiences. A majority of respondents were White males who displayed at least some level of post-secondary education. The findings indicated that respondents who used psychedelics for specifically religious purposes, as well as those who identified with a religion, were more likely to score higher on the Mysticism Scale than those who did not.

Dark Classics in Chemical Neuroscience: N, N-Dimethyltryptamine (DMT).

July 23, 2018 / DMT, Papers, Psychology, Publications / By / ,

Abstract

Though relatively obscure, N, N-dimethyltryptamine (DMT) is an important molecule in psychopharmacology as it is the archetype for all indole-containing serotonergic psychedelics. Its structure can be found embedded within those of better-known molecules such as lysergic acid diethylamide (LSD) and psilocybin. Unlike the latter two compounds, DMT is ubiquitous, being produced by a wide variety of plant and animal species. It is one of the principal psychoactive components of ayahuasca, a tisane made from various plant sources that has been used for centuries. Furthermore, DMT is one of the few psychedelic compounds produced endogenously by mammals, and its biological function in human physiology remains a mystery. In this review, we cover the synthesis of DMT as well as its pharmacology, metabolism, adverse effects, and potential use in medicine. Finally, we discuss the history of DMT in chemical neuroscience and why this underappreciated molecule is so important to the field of psychedelic science.

Blood pressure safety of subanesthetic ketamine for depression: A report on 684 infusions

July 19, 2018 / Depressive Disorders, Ketamine, Papers, Psychology, Publications / By / , , , , , ,

Abstract

BACKGROUND:
The dissociative anesthetic agent ketamine is increasingly being utilized to treat depression, despite not having FDA (Food and Drug Administration) approval for this indication. There are many questions about the potential risks of this treatment and hence the proper setting and degree of monitoring required to ensure patient safety. There is limited data about the cardiovascular safety of ketamine when administered at subanesthetic doses to treat depression.
METHODS:
66 patients in the Department of Psychiatry at Emory University received a total of 684 ketamine infusions between 2014 and 2016. Ketamine was dosed at 0.5 mg/kg body weight and infused over 40 min. Blood pressure was measured every 10 min during the infusions and every 15 min thereafter.
RESULTS:
Mean age of the patients was 56.7 years, 87.9% had unipolar depression and 36.1% had essential hypertension. No infusions were discontinued due to instability of vital signs, adverse physiological consequences or acute psychotomimetic effects. The biggest increases in blood pressure were measured at 30 min (systolic 3.28 mmHg, diastolic 3.17 mmHg). Hypertensive patients had higher blood pressure peaks during the infusions. Blood pressures returned to baseline during post-infusion monitoring. There was no development of tolerance to the blood pressure elevating effects of ketamine between the first and sixth infusions.
LIMITATIONS:
This is a single site, retrospective analysis, of patients who were spontaneously seeking clinical care.
CONCLUSIONS:
The blood pressure changes observed when ketamine is administered over 40 min at 0.5 mg/kg for the treatment of depression are small, well tolerated and clinically insignificant.
