This review argues that qualitative research on psychedelic treatments can reveal unique features of different substances and uncover implications for treating specific psychiatric disorders that quantitative methods might miss. By examining subjective experiences, such studies can help tailor therapies to particular conditions and substances, offering insights into how psilocybin, LSD, or other compounds produce distinct psychological effects. The authors suggest that incorporating qualitative findings into clinical practice could enhance treatment precision and patient outcomes, highlighting the value of exploring personal narratives and emotional processes in psychedelic therapy.

Patients with treatment-resistant depression undergoing oral esketamine treatment often find the experience overwhelming and struggle with whether to let go or maintain control. Their ability to let go is influenced by preparation, emotional support, and the treatment setting. Better preparation, an optimized environment, and psychological support during sessions may improve patients' experiences and outcomes. The study provides recommendations for improving quality of care, including training for nurses and support staff.

Reporting on the psychological intervention component of psychedelic-assisted psychotherapy is mostly incomplete and inconsistent across studies, limiting replicability and clinical translation. A systematic review of 45 original studies on psilocybin, MDMA, LSD, or ayahuasca for mental disorders found that descriptions of psychotherapy varied widely and completeness of information was generally low, based on an adapted Template for Intervention Description and Replication checklist. Studies involving MDMA showed more homogeneous psychotherapy and more procedural details. Improved reporting on psychological interventions would support replicability, generalisability, and accurate interpretation of research, as well as enhance feasibility and safety of future clinical research and real-world implementation.

The effects of oral esketamine for treatment-resistant depression are highly variable, and psychological distress is common. Patients report perceptual changes, detachment from body and emotions, stillness, mystical-type experiences, and fear. After sessions, many feel hungover and fatigued, while depressive mood is neutralized. Some effects, such as increased openness and detachment, may hold psychotherapeutic potential, but the frequent distress calls for additional patient support throughout treatment.
