In Nathan’s view, the psychedelic field in the western world, specifically The Netherlands and surrounding countries, seems to be split into two worlds: the neo shamanic, and the academic / clinical one. Each has its own language, its own rituals, its own gatekeepers.
But if our goal is to have a society where psychedelics are fully integrated and normalized, then we need to speak about the large space in between. The biggest group of people who aren’t interested in both worlds.
Join Nathan in an open conversation exploring:
  • What language do we use to speak to the middle ground? and what skills?
  • How can we make psychedelic experiences accessible, and how do we offer it?
  • And maybe more important: is his perspective accurate or is he missing something?

About Peer Perspectives

Peer Perspectives is a member-led series within the OPEN Plus Tier. Each session highlights the depth, diversity, and creativity of work emerging from within our own network. Professionals are invited to host a 60-minute gathering to share research, clinical insights, embodied practices, or cultural perspectives, followed by open discussion and Q&A. These sessions are designed to support peer-to-peer learning in a warm, collegial space and to celebrate the knowledge already present within our community.

With his practise, he offers safe, accessible and ethical psychedelic workshops and ceremonies in a non-shamanic and non-clinical way.
