Understanding subjective experience in psychedelic-assisted psychotherapy: The need for phenomenology.

Psychedelic-assisted psychotherapy is being investigated as a treatment for a range of psychiatric illnesses. Current research suggests that the kinds of subjective experiences induced by psychedelic compounds play key roles in producing therapeutic outcomes. To date, most knowledge of therapeutic psychedelic experiences are derived from psychometric assessments with scales such as the Mystical Experience Questionnaire.

Psychedelic injustice: should bioethics tune in to the voices of psychedelic-using communities?

Psychedelic compounds are regaining widespread interest due to emerging evidence surrounding their therapeutic effects. The controversial nature of these compounds highlights the need for extensive bioethical input to guide the process of medicalisation. To date there is no bioethics literature that consults the voices of psychedelic-using communities in order to help guide normative considerations of psychedelic medicalisation.

Psychedelic-assisted psychotherapy for the treatment of major depression: a synthesis of phenomenological explanations.

Psychedelic-assisted Psychotherapy (PAP) combines the use of psychedelic compounds, such as psilocybin, with psychotherapy. PAP has shown some promise as a novel treatment for Major Depressive Disorder (MDD), and empirical research suggests that its efficacy turns on the altered states induced by psychedelic compounds. In this paper we draw on the literature of phenomenology to explain the therapeutic potential of psychedelic experiences.

Prescribing meaning: hedonistic perspectives on the therapeutic use of psychedelic-assisted meaning enhancement.

The recent renaissance in research on psychedelic-assisted psychotherapy is showing great promise for the treatment of many psychiatric conditions. Interestingly, therapeutic outcomes for patients undergoing these treatments are predicted by the occurrence of a mystical experience-an experience characterised in part by a sense of profound meaning. This has led to hypotheses that psychedelic-assisted psychotherapy is therapeutic because it enhances perception of meaning, and consequently leads to a meaning response (a therapeutic mechanism that has been well described in the philosophical literature on the placebo effect).
