The California Poison Control System (CPCS) operates as a statewide poison management network divided into several regional divisions, each overseen by physician medical directors. Two prominent medical directors within this system are **Dr. Craig Smollin** and **Dr. Cyrus Rangan**. **Dr. Craig Smollin** serves as the Medical Director of the San Francisco Division of CPCS [1]. He earned his medical degree from the University of California, San Francisco (UCSF) and completed emergency medicine residency and a medical toxicology fellowship [1]. He holds an academic appointment as a Professor of Emergency Medicine at UCSF School of Medicine [1]. His primary clinical and research interests center on emergency toxicology, envenomation management, drug overdose treatment, and the intersection of toxicology with public health. He is actively involved in teaching medical students and residents in both emergency medicine and clinical toxicology [1]. **Dr. Cyrus Rangan** serves as the Medical Director associated with the CPCS and also holds the position of Director of the Toxicology and Environmental Assessment Bureau at the Los Angeles County Department of Public Health [2]. He received his medical degree from the Chicago Medical School and completed training in pediatrics as well as a fellowship in medical toxicology [2]. His academic appointments include a clinical faculty position affiliated with the University of California system. Dr. Rangan's primary interests focus on pediatric toxicology, environmental health, lead poisoning prevention, and public health toxicology, particularly assessing chemical exposures in community settings [2]. Comparing the two, Dr. Smollin's background emphasizes emergency medicine and acute clinical toxicology within an academic medical center, while Dr. Rangan integrates pediatric medicine with environmental and public health-oriented toxicology. Both hold university-affiliated teaching roles and contribute to poison management policy, but their subspecialty emphases—acute care versus environmental and pediatric toxicology—reflect complementary expertise within CPCS. ## References [1] University of California, San Francisco.

Shideh Pouria, MD, is a medical director within the California Poison Control System (CPCS) and Assistant Professor of Emergency Medicine at UC San Diego. She completed medical school at the University of Rochester, then an emergency medicine residency at UC San Diego and a medical toxicology fellowship at the Toxikon Consortium in Chicago.[1][2] Her academic appointment is in Emergency Medicine, with clinical roles in both emergency and inpatient toxicology consultation. Her interests include acute poisoning management, envenomations, and medical education in toxicology, reflected in her work supervising fellows and residents and contributing to toxicology curricula.[1][2] Craig Smollin, MD, serves as Medical Director of the San Francisco Division of CPCS and is a Professor of Emergency Medicine at UCSF.[3][4] He obtained his MD from Jefferson Medical College, completed emergency medicine residency at Brown University, and a medical toxicology fellowship at UCSF.[3] His academic role is more senior, involving leadership in the UCSF Division of Medical Toxicology and direction of the UCSF medical toxicology fellowship.[3][4] Smollin’s primary interests include clinical toxicology, antidote use, and outcomes research in poisoning, as well as systems-level toxicology practice and education.[3][4] In comparison, both are emergency physicians and fellowship-trained medical toxicologists working as CPCS medical directors and academic faculty. Pouria’s profile emphasizes clinical toxicology care and education, whereas Smollin’s adds a larger focus on fellowship leadership and research in toxicology outcomes and systems of care.[1–4] ## References [1] UC San Diego Department of Emergency Medicine – Shideh Pouria, MD profile.
