Abstract

Health-related psychedelic research should focus on helping us flourish, not just remedying ill-health or addiction. We don’t know enough about how psychedelics could enhance human flourishing. Factors promoting health-through-flourishing include finding meaning in life, spiritual practices, comfortable levels of social bonds, emotionally/physically satisfying sex in a long-term monogamous relationship and control over one’s daily life. Psychedelic research could find more.Neuroscience anchors psychedelic research into disease and disorder, e.g. addiction, PSTD, migraine, anxiety, pain etc. Neurophenomenological psychedelics research could illuminate relationships between health, ASC/NOSCs and cognitive liberty to promote human flourishing. If we accept the self as an epiphenomenon of subsystems within the brain, we ‘know’ ‘unconsciously’, but are not aware of, many things which affect our lives profoundly. These include control over identifying, remembering and forgetting our states of mind and how to move between them. A prerequisite for integrated investigations into ASC/NOSCs is the establishment of a taxonomic knowledge base which lists, categorises and characterises ASC/NOSCs to enable us to choose specific states of mind and move securely among them. Or, in other words, to enable us to exercise our cognitive liberty safely.

I believe that human health and flourishing would be enhanced were we able to direct our states of being by consciously choosing them. Given the promise of mindfulness techniques to enhance our health, happiness and spiritual growth, constructing both personal and generic classifications of salient ASC/NOSCs makes sense. Laws need to change. The neuroscience of pleasure, love, spirituality, decision-making, pattern recognition and location of meaning should inform health-enhancing psychedelic research while promoting flourishing through cognitive liberty.

As part of cognitive liberty, our end-of-life choices should include how we die. In other words, our idea of the good death should include access to psychedelics. Dying high is increasingly likely to become a popular choice as baby boomers age and place their economic clout behind the reform of end-of-life laws as well as drug laws. Achieving such crucial legal changes depends partly on the ability to produce research to anchor evidence based law and policy. Research into psychedelics, ASC/NOSCs and the neurobiology of the dying process is essential.

Introduction to ‘Beneficial Effects of Psychedelics with a Special Focus on Addictions’

The articles dedicated to psychedelic research in this issue of Current Drug Abuse Reviews are part of a special issue dedicated to the beneficial uses of psychedelics, with a special focus on addiction. The beneficial uses of psychedelics are currently being studied at some of the world’s major academic institutions. Research teams are investigating their potential in addressingvarious hard to treat psychiatric disorders, such as post-traumatic stress disorder, end-of-life anxiety, drug dependence and depression. After a decades long hiatus, psychedelic research is once again establishing a firm foothold in academia.

The idea of this special issue originated at the Interdisciplinary Conference on Psychedelic Research, organised by the OPEN Foundation in 2012. OPEN was founded in 2007 in the Netherlands, in order to stimulate and advance scientific research into psychedelics. In this second part of the special interdisciplinary issue of CDAR, specific attention is paid to the role psychedelics may play in mental health, in particular with regard to addiction and drug dependence.

Abstract

Interest in the therapeutic potential of psychedelic substances has recently resumed. During an early phase of human psychedelic research, their therapeutic application in different pathologies had been suggested, and the first evidence for efficacy was provided. The range of recent clinical applications of psychedelics spans from cluster headaches and obsessive-compulsive disorder to addiction and the treatment of fear and anxiety in patients suffering from terminal illness, indicating potentially different therapeutic mechanisms. A variety of approaches in psychotherapy emphasize subjective experiences, such as so-called peak experiences or afterglow phenomena, as differentially mediating therapeutic action. This review aims to re-evaluate earlier and recent concepts of how psychedelic substances may exert beneficial effects. After a short outline of neurophenomenological aspects, we discuss different approaches to how psychedelics are used in psychotherapy. Finally, we summarize evidence for the relationship between subjective experiences and therapeutic success. While the distinction between pharmacological and psychological action obviously cannot be clear-cut, they do appear to contribute differently from each other when their effects are compared with regard to pathologies.

Abstract

New World indigenous peoples are noted for their sophisticated use of psychedelic plants in shamanic and ethnomedical practices. The use of psychedelic plant preparations among New World tribes is far more prevalent than in the Old World. Yet, although these preparations are botanically diverse, almost all are chemically similar in that their active principles are tryptamine derivatives, either DMT or related constituents. Part 1 of this paper provides an ethnopharmacological overview of the major tryptamine-containing New World hallucinogens.

Drug models of schizophrenia

Abstract

Schizophrenia is a complex mental health disorder with positive, negative and cognitive symptom domains. Approximately one third of patients are resistant to currently available medication. New therapeutic targets and a better understanding of the basic biological processes that drive pathogenesis are needed in order to develop therapies that will improve quality of life for these patients. Several drugs that act on neurotransmitter systems in the brain have been suggested to model aspects of schizophrenia in animals and in man. In this paper, we selectively review findings from dopaminergic, glutamatergic, serotonergic, cannabinoid, GABA, cholinergic and kappa opioid pharmacological drug models to evaluate their similarity to schizophrenia. Understanding the interactions between these different neurotransmitter systems and their relationship with symptoms will be an important step towards building a coherent hypothesis for the pathogenesis of schizophrenia.

Abstract

Kosmicare project implements crisis intervention in situations related to the use of psychoactive substances at Boom Festival (Portugal). We present evaluation research that aims to contribute to the transformation of the project into an evidence-based intervention model. It relies on harm reduction and risk minimization principles, crisis intervention models, and Grof’s psychedelic psychotherapy approach for crisis intervention in situations related to unsupervised use of psychedelics. Intervention was expected to produce knowledge about the relation between substance use and mental health impact in reducing potential risk related to the use of psychoactive substances and mental illness, as well as an impact upon target population’s views of themselves, their relationship to substance use, and to life events in general. Research includes data on process and outcome indicators through a mixed methods approach, collected next to a sample of n=176 participants. Sample size varied considerably, however, among different research measures. 52% of Kosmicare visitors reported LSD use. Over 40% also presented multiple drug use. Pre-post mental state evaluation showed statistically significant difference (p<.05) confirming crisis resolution. Crisis episodes that presented no resolution were more often related with mental health outburst episodes, with psychoactive substance use or not. Visitors showed high satisfaction with intervention (n=58) and according to follow-up (n=18) this perception was stable over time. Crisis intervention was experienced as very significant. We discuss limitations and implications of evaluating natural setting based interventions, and the relation between psychoactive substance use and psychopathology. Other data on visitor’s profile and vulnerability to crisis showed inconclusive.

A Qualitative Report on the Subjective Experience of Intravenous Psilocybin Administered in an fMRI Environment

January 28, 2015 / Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , ,

Abstract

Background: This report documents the phenomenology of the subjective experiences of 15 healthy psychedelic experienced volunteers who were involved in a functional magnetic resonance imaging (fMRI) study that was designed to image the brain effects of intravenous psilocybin.

Methods: The participants underwent a semi-structured interview exploring the effects of psilocybin in the MRI scanner. These interviews were analysed by Interpretative Phenomenological Analysis. The resultant data is ordered in a detailed matrix, and presented in this paper.

Results: Nine broad categories of phenomenology were identified in the phenomenological analysis of the experience; perceptual changes including visual, auditory and somatosensory distortions, cognitive changes, changes in mood, effects of memory, spiritual or mystical type experiences, aspects relating to the scanner and research environment, comparisons with other experiences, the intensity and onset of effects, and individual interpretation of the experience.

Discussion: This article documents the phenomenology of psilocybin when given in a novel manner (intravenous injection) and setting (an MRI scanner). The findings of the analysis are consistent with previous published work regarding the subjective effects of psilocybin. There is much scope for further research investigating the phenomena identified in this paper.
