THIS WEDNESDAY (July 15): National Contingency Management Community of Practice
The National Contingency Management (CM) Community of Practice (CoP), led by Michigan Medicine (University of Michigan), is intended to serve as a collaborative learning forum, bringing together researchers, treatment providers, implementers, TTA leaders, state agencies, and other partners in CM interested in expanding access to evidence-based CM. The goal is to create a practical, engaging, and implementation-focused space to share best practices, discuss challenges and solutions, and support broader adoption and sustainability of evidence-based CM across the U.S. Join the CM CoP monthly meetings to ask questions, share what is working, and learn from CM experts across the country! The first meeting of the National CM CoP is THIS WEDNESDAY, July 15, 2026, from 1-2pm ET. Find out more and register here!

Western States Node Webinar: Problems Initiating Buprenorphine Treatment Among Patients Using Fentanyl (Feb 25, 2026) CME available!
Join the CTN Western States Node and the Northwest and Pacific Southwest Addiction Technology Transfer Centers (ATTCs) for their next joint webinar, February 25, 2026, 11am-12:30pm PT! In this session, Erin Winstanley, PhD (CTN Appalachian Node), will describe a NIDA Clinical Trials Network study, CTN-0135, examining clinician-reported challenges with initiating buprenorphine for people using fentanyl, including precipitated or prolonged withdrawal, patient reports that buprenorphine was ineffective, and patient preference for methadone. In response to these challenges, most clinicians surveyed reported modifying their standard induction protocols or patient counseling approaches. Clinicians treating larger patient volumes, seeing a high proportion of patients using fentanyl, or initiating treatment in non-inpatient settings were more likely to report difficulties starting patients on buprenorphine. Dr. Winstanley will present the study results and discuss their implications. 1.5 CME/CE available! For information about credit types and accreditation, as well as learning objectives for this session, download the webinar flyer. Register for the webinar here! Posted on February 11, 2026
