ADDINT is built and curated by Shanli Parnia, MD — a physician board-certified in Addiction Medicine by the American Board of Preventive Medicine (ABPM, 2025), with additional board certifications in Internal Medicine (ABIM, 2022) and Obesity Medicine (ABOM, 2023).
Dr. Parnia is an attending hospitalist and addiction medicine physician at Loretto Hospital, a safety-net community hospital on Chicago's West Side. Her clinical work spans three overlapping services:
- Inpatient hospital medicine. She admits and manages adults across the full internal-medicine census — infection, decompensated chronic disease, complications of substance use, and the acutely ill patients transferred up from the emergency department.
- Open-ICU critical care. Loretto operates an open intensive care unit, meaning the admitting hospitalist remains the physician of record for critically ill patients — managing vasopressors, mechanical ventilation, sepsis resuscitation, and end-of-life conversations without handing patients off to a separate intensivist service.
- Inpatient detoxification. She oversees care for patients admitted to the hospital's detox program — opioid, alcohol, benzodiazepine, and polysubstance withdrawal — and manages the medical complications that these patients present with in a population that is disproportionately uninsured, unhoused, and cut off from routine care.
She also provides general internal-medicine care in the outpatient clinic and mentors psychiatry resident physicians and medical students.
Research on the emerging drug supply

- Neptune's Fix — Gas-station Heroin and Its Impact: A Systematic Review and Post-Hoc Analysis of Tianeptine Exposure Cases — BMC Public Health, in press; poster, APA Mental Health Services Conference, Baltimore, Sept 2024.

Training
Dr. Parnia completed internal medicine residency at Morehouse School of Medicine, rotating at Grady Memorial Hospital and the Atlanta VA, where she led COVID-19 clinical outcomes research as principal investigator. She interned at Nassau University Medical Center on Long Island during the first wave of the pandemic. She earned her M.D. from the American University of the Caribbean and holds a combined B.S. in Microbiology and Oceanography from the University of British Columbia.
Why ADDINT exists
The clinicians treating the drug supply's casualties are the last to hear what is in it. Xylazine was in the fentanyl supply for years before most inpatient teams learned to recognize its wound care and withdrawal profile. Medetomidine displaced it before the last CME cycle finished. Nitazenes, then orphines, then whatever comes next — the surveillance data exist, in public feeds, in different formats, in different agencies. ADDINT is a translation layer: public sources in, one page of clinical bedside language out. Free. No accounts. No tracking. Every card links its primary source.
