Dennis McKenna joins 3L1T3 and Valerie Beltran to discuss the future of psychedelics, indigenous knowledge, and whether we are ready to bring these tools into mainstream culture without repeating the extractive patterns of the past. We explore the gap between good intentions and real reciprocity, what Western psychedelic enthusiasm is missing, and how community-based practice may matter more than clinical models alone.

We also dive into the first biomedical study of ayahuasca with the UDV, how long-term members showed surprising changes in behavior and biology, and why the community structure may have played a larger role than the compound itself. Dennis talks about the work happening at the McKenna Academy, preserving Amazonian herbarium collections, digitizing ancestral plant knowledge, and the ESPD Symposia.

This conversation calls out the cultural side of psychedelics, not just the science. If psychedelics are going to help, they must be integrated with wisdom, not just technology.

Key Points

• Psychedelics entered global awareness through indigenous stewardship, not Western invention
• Reciprocity requires more than money and acknowledgment
• The ESPD Symposia preserve ethnobotanical knowledge and make it public
• Efforts to digitize herbarium collections in Peru before they are lost
