Fayaz Ibrahim, MD
Dr. Fayaz Ibrahim is a double board-certified psychiatrist and addiction medicine specialist with more than fifteen years of forensic experience.
He completed his psychiatry residency at SUNY Downstate Medical Center, including a six-month elective at Columbia University's Center for Movement Disorders. This training established a clinical foundation spanning the psychiatric, neurological, and pharmacological dimensions of injury and impairment.
His medico-legal practice focuses on the intersection of psychiatric illness, substance use, workplace injury, and causation—particularly the questions that drive contested claims: Did an event, substance, or pre-existing condition credibly cause the claimed injury, at the claimed severity, and for the claimed duration?
As an experienced California QME and psychiatric expert witness, Dr. Ibrahim combines dual board certification in Psychiatry and Addiction Medicine with a Master Psychopharmacology credential from the Neuroscience Education Institute (NEI) to provide comprehensive, evidence-based, and defensible medico-legal opinions.
Dr. Ibrahim brings particular expertise to cases involving cannabis, psychedelics, and emerging psychoactive compounds. He completed the year-long Psychedelic-Assisted Therapies and Research program at the California Institute of Integral Studies (CIIS), with additional training relevant to psilocybin, LSD, DMT, mescaline, MDMA, ketamine, and related compounds. This expertise supports evaluation of their psychiatric effects, substance-related complications, causation, and impairment within a medico-legal framework.
Dr. Ibrahim has also held academic appointments, including Adjunct Assistant Professor at A.T. Still University School of Osteopathic Medicine and Vice-Chair of Psychiatry at KDHCD–UC Irvine School of Medicine. His peer-reviewed publications span geriatric psychiatry, psychopharmacology, and complex neuropsychiatric presentations.
