Current evidence suggests that the efficacy of psychedelic therapy depends, in part, on the character of psychedelic experiences themselves. One pronounced aspect of psychedelic experiences is alterations to the experience of time, including reports of timelessness or transcending time. However, how we should interpret such reports remains unclear, and this lack of clarity has philosophical and...

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...

Abstract Psychedelic-assisted psychotherapy is an emerging psychiatric treatment that is attracting significant scientific, medical, and public attention. Whilst preliminary results from empirical studies are promising, the medical use of these compounds is highly controversial. Surprisingly, and despite the current controversies caused by the re-medicalisation of psychedelics, bioethicists...

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...
