A review sponsored by a public-private partnership addresses clinical trial design for new opioid use disorder (OUD) treatments that target systems other than the μ-opioid receptor. The authors present consensus recommendations for evaluating novel therapies such as cannabinoids, psychedelics, sedative-hypnotics, and immunotherapeutics. Key design elements include specifying the treatment stage (e.g., early abstinence, long-term recovery), defining the treatment's role (adjunctive or independent), selecting patient-informed primary outcomes that assess opioid use patterns, retention, and quality of life, and monitoring adverse events like relapse or overdose, especially when patients are not on maintenance opioid agonist or antagonist medications. Incorporating input from people with lived experience is urged to accelerate development and uptake of effective therapeutics.

Psychedelic substances have been used historically for spiritual and mystical experiences, and recent interest focuses on their potential to treat chronic pain. Clinical trials support psychedelics' effectiveness for psychiatric conditions, but studies on chronic pain—such as cancer pain, phantom limb pain, migraine, and cluster headache—are few and mostly uncontrolled. Risks are relatively rare with careful patient screening and supervision. Key challenges include identifying mechanisms of action, selecting appropriate pain conditions, designing rigorous trials with proper control groups, minimizing unblinding bias, and accounting for patient mindset and setting. Evidence-based recommendations are needed for future research to yield informative results.

A systematic review of 91 fMRI studies on acute psychedelic effects found substantial methodological heterogeneity. Only 51 unique samples were used across the 91 papers, and 54% of studies did not meet current standards for correcting Type I errors or controlling motion artifacts. Psilocybin and LSD consistently modulated connectivity along the sensorimotor-association cortical axis. Ketamine consistently increased activation in the dorsomedial prefrontal cortex. The review calls for future adoption of pre-registration, standardized processing and statistical testing, and data sharing to improve rigor.

Roland R. Griffiths was a highly influential scientist in behavioral and neuropsychopharmacology, known for his rigorous research on abuse liability of substances including alcohol, benzodiazepines, caffeine, tobacco, and psychedelics. This review, authored by his former mentees and collaborators, describes his methodical approach to research, his inclusive and collegial mentoring style, and his role in advancing scientific methods for abuse liability assessment, policy, and regulation. His work culminated in the establishment of the Johns Hopkins Center for Psychedelic and Consciousness Research, reflecting his curiosity-driven, humanity-serving science that continues to inspire innovation.
