For decades, the U.S. government banned medical studies of the effects of LSD. But for one longtime, elite researcher, the promise of mind-blowing revelations was just too tempting.

FROM THE ARTICLE: But here’s the clincher. After their 5HT2A neural receptors simmered down, they remained firm: LSD absolutely had helped them solve their complex, seemingly intractable problems. And the establishment agreed. The 26 men unleashed a slew of widely embraced innovations shortly after their LSD experiences, including a mathematical theorem for NOR gate circuits, a conceptual model of a photon, a linear electron accelerator beam-steering device, a new design for the vibratory microtome, a technical improvement of the magnetic tape recorder, blueprints for a private residency and an arts-and-crafts shopping plaza, and a space probe experiment designed to measure solar properties. Fadiman and his colleagues published these jaw-dropping results and closed shop.
