We are excited to announce the launch of Acta Psychedelica, a fully open-access, peer-reviewed, and non-profit journal dedicated to interdisciplinary psychedelic research. Run by researchers in the field, the journal aims to foster rigorous and open scientific discourse on psychedelics. The journal is published by the Finnish Association for Psychedelic Research (Psykedeelitutkimusyhdistys ry).

We now invite submissions for our first issues:

1. Special Issue: “What is (a) psychedelic?”

   This special issue explores fundamental questions about the definition and scope of psychedelics. Topics of interest include, but are not limited to:

• What qualifies as a psychedelic substance, activity, or experience?
• How should the term “psychedelic” be conceptualized?
• In what ways do psychedelic experiences compare to other transformative states, such as meditation, near-death experiences, or spontaneous awakenings?
2. General Call for Papers

   We also welcome submissions on any topic related to psychedelic substances and experiences, spanning all fields of research.

Acta Psychedelica is an interdisciplinary journal and accepts submissions from psychology, psychiatry, philosophy, pharmacology, neuroscience, anthropology, sociology, religious studies, theology, and related disciplines. The journal is published on the journal.fi platform used by the majority of Finnish scientific journals, and there are no publication fees.

Manuscripts should be submitted via our online system: https://actapsychedelica.journal.fi/about/submissions

Submission deadline for the special issue “What is (a) psychedelic?” is August 31, 2025. Other submissions are considered continuously, and all accepted submissions are published online ahead of inclusion in issues.
