Ten years ago Dr. Katherine MacLean conducted the first scientific study of the combined effects of psychedelics with meditation. The encouraging results of the study showed the long-term beneficial effects these substances can have on our concentration, emotion regulation, openness, wellbeing, and happiness. In our conversation I learned what psychedelics have in common with meditation and how they can compliment one another. Katherine also shared when psychedelics aren't useful or even when they can be harmful. She offers careful advice as to when these substances might be of benefit and when they aren't.
