Research Projects
2024 Brain Mapping Study Partnered with Neuro Enlightenment
In 2024 we partnered with NeuroEnlightenment, a company that specializes in mapping the brain and looking for signs of brain function improvements focusing on neuroplasticity and neurogenesis. They measured four of our guests prior to the start of the dieta and then the day after the dieta closed, mapping how the brain changed over the course of the dieta (7 days in total). Luke Jensen, the founder and a clinician, described the results as “extraordinary and significant, really high level of change in such a short time.” Average markers of change include the normalization and neuroplasticity rates, which on average were 43 and 35% respectively. Some guests even achieved upwards of 50% normalization rates.
We were very pleased with these results and help confirm the long-held belief and intention to help to open our guests brains and beings to new paths, infused with the embodied wisdom of tobacco and the plants we work with.
We hope to continue these research studies with more participants, for longer durations of time, and tracking guests retention of these effects over the course of 1, 3, 6 months and 1 year after the completion of the dietas.

This is a labor of love and requires significant time and resources. If you feel called to support our vision of bridging modern science with ancient wisdom, any donations would be much appreciated. Thank you in advance!
