Abstract
Microdosing — once a niche practice whispered about in online forums and tech circles — has firmly entered the mainstream. A new RAND survey suggests that millions of U.S. adults are now taking sub‐perceptual amounts of psychedelics such as psilocybin, LSD and MDMA, often with goals that differ sharply from those associated with traditional, full‐dose use.
