California Substance Use Line

The California Substance Use Line (CSUL) is a round-the-clock, cost-free tele-consultation service for substance use evaluation and management that is available to all California clinicians in any health care setting. The CSUL is a unique collaboration between the California Poison Control System (CPCS) and the National Clinician Consultation Center (NCCC) at the University of California, San Francisco. The CSUL offers on-demand, 24/7 assistance to clinicians of any level of experience. Our expert physicians, clinical pharmacists, and advanced practice nurses are standing by to provide evidence-based guidance and clinical decision support on evaluation and management of opioid, alcohol, and other substance use. The CSUL can help clinicians by:

  • Providing point-of-care assistance — no matter how basic or complex the scenario — and helping to guide treatment planning.
  • Building skills, capacity, and confidence with substance use management or treatment, including connecting callers with general information and resources.
  • Guiding development and implementation of protocols for opioid overdose/withdrawal and its aftercare.
  • Welcoming follow-up calls for continued conversations.
