Topic guide

Psilocybin

A structured route through psilocybin research, depression trials, microdosing claims, safety screening and UK legal context.

Start with context

Psilocybin findings are shaped by dose, setting, psychological support, participant selection, expectancy and follow-up. Results from tightly controlled studies should not be treated as instructions for unsupervised use.

Questions this topic raises

  • What did the study actually compare?
  • Were participants and assessors successfully blinded?
  • Who was excluded on safety grounds?
  • How long did any reported benefit last?
  • Does research access translate into legal or routine clinical access?
