This Week's Focus: 5th Annual NDEWS Summit at the 2026 College on Problems of Drug Dependence (CPDD)

 
ndews_summit_photo
 

The 5th Annual NDEWS Summit convened this week in Portland, Oregon, in conjunction with the 88th Annual College on Problems of Drug Dependence. NDEWS Sentinel Site Directors, Scientific Advisors, Community Based Health Experts, members of the Coordinating Center, affiliates, NIDA leadership and interested scientists spent four hours (even during the Knicks vs Spurs game) updating each other on emerging drugs and other trends in their areas.

Anecdotally, we heard people thought it was the best Summit yet, but stay tuned for a survey! To extend this enthusiasm, we focus this week’s NDEWS Weekly Briefing on the science we presented. But first, we thank CPDD for letting us meet ahead of the meeting and look forward to being in Toronto, Canada, next year. SAVE THE DATE for the next Summit on June 26th, 2027, in tandem with the first day of the CPDD meeting, June 26 to 30, 2027.

Those of us who have been going to CPDD, whether it was our first time or our 34th time, enjoyed our time there. In the Briefing today, we share the topics presented by our NDEWS extended family.

As always, we welcome your input.

ABOUT NDEWS

 
 

The NDEWS Weekly Briefing curates emerging data and findings from across the Early Warning Network, which includes three core components: our Scientific Advisory Group (SAG), comprised of national experts and federal partners; our Sentinel Site Directors (SSDs), who lead local surveillance in key geographic regions; and our Community-Based Health Experts, who provide on-the-ground insights from populations most impacted by drug trends. Together, these contributors generate timely, multidisciplinary and impactful information, ranging from peer-reviewed research findings to local surveillance data. These contributions inform public health and research communities.
