A survey of 151 psychiatrists in Ireland found that most hold positive attitudes toward psilocybin therapy: 81.5% agreed it shows promise for treating psychiatric disorders, 86.8% supported funding research, 86.8% would refer a patient if licensed, and 78.1% would consider it for themselves. However, only 40.0% felt knowledgeable and just 9.9% felt adequately prepared to participate. A minority expressed concerns: 6.6% thought it unsafe under medical supervision, 21.9% considered it potentially addictive, and 15.9% reported at least one concern about evidence, effectiveness, safety, cost, or impartiality. Consultant psychiatrists were less optimistic than trainees about its role in bipolar depression and emotionally unstable personality disorder.
Classical serotonergic psychedelics like psilocybin show emerging evidence of therapeutic potential across depression, anxiety, and substance use disorders, with indications of transdiagnostic efficacy. Early-phase studies yielded encouraging results, but recent larger-scale phase 3 trials for treatment-resistant depression have shown more modest effects. No regulatory approvals from the U.S. FDA or EMA exist, though a few countries permit psychedelic therapies in regulated clinical settings. The long-term trajectory and real-world impact within public health systems remain uncertain. This paper examines challenges for integrating psychedelic therapies into Ireland's public healthcare system, covering regulatory approval, Health Technology Assessment, service implementation, workforce capacity, and evaluation of long-term patient outcomes.
