You've probably heard about microdosing, which involves taking a small, "sub-perceptual" dose of psychedelics like LSD or psilocybin on a regular basis to ward off depression, anxiety, and chronic pain—or to optimize focus and boost energy.

Today's guests are James Fadiman and Jordan Gruber, authors of the new book Microdosing for Health, Healing, and Enhanced Performance. Fadiman, a Stanford-trained research psychologist who has been working with psychedelics since the early 1960s, popularized the concept of microdosing over a decade ago. They talk with Reason's Nick Gillespie about the mechanics of and theory behind microdosing, its promise and limits, and how it fits into the larger psychedelic renaissance that has been flowering for most of the 21st century. And they discuss the prospects for legalization and cultural normalization of psychedelics under the Trump administration.
