How LSD travelled from CIA project to counterculture to Schedule I. The politics, documented.

Terence McKenna advances a sweeping cultural-evolutionary argument that psychoactive plants and fungi shaped human consciousness and society across history. PMG includes it as a touchstone for the anthropological and historical framing around psilocybin and related substances. It is a work of speculative cultural history and personal theory, not clinical research, and its claims should be read as McKenna's interpretive argument rather than established science.
