The undersigned individuals and organizations work to advance the understanding and beneficial uses of substances called (among many names) psychedelics, hallucinogens, or entheogens. Our fields include medicine and traditional healing, medicinal chemistry and ethnopharmacology, psychopharmacology, neuroscience, psychology, counseling, religion, public health, and public policy. From generations of practitioners and researchers before us, we have received knowledge about these substances, their risks, and ways to use them constructively. In turn, we accept the call to use that knowledge for the common good and to share freely whatever related knowledge we may discover or develop. Therefore, in this work, we commit to the following principles. If we engage with consultants, contractors, or suppliers, we will do so in ways that uphold these principles.
