The State of Mushroom & Psychedelic Research: July 2026

The big picture. ShroomWire is tracking 2397 mushroom & psychedelic studies, each graded A–F for evidence strength. Here’s where the evidence actually stands right now — including how much is still early-stage, what’s preprint, and what’s been retracted.

Evidence strength across what we track

Most of the field is still early — and we think saying so plainly is the point.
