Abstract

Summary The use for hallucinogenic purposes of an indigenous mushroom, Psilocybe semilanceata indigenous to Britain is reported in three patients. Typical psychedelic, transient psychotic and more prolonged schizophrenia-like states were seen, with sympathomimetic signs noted in two cases, in one being prolonged. Enquiry about such mushroom abuse should be considered in individuals presenting to medical or psychiatric emergency clinics.
