Supporting Addiction Recovery

The Addiction Medicine Working Group at UCLA – Ronald Reagan Hospital aims to help engage patients with substance use disorder in evidence-based medical and behavioral treatment for intoxication, withdrawal, and long-term outpatient management. We work in the inpatient wards, the emergency department and in bridge/longitudinal clinics. In addition to guideline-based medical care, we work to destigmatize our patients and create an environment where patients' concerns are heard and validated with compassion and professionalism.
