About nDEWS


Coordinating Center

NDEWS is led by scientists from the University of Florida, New York University, and Florida Atlantic University. Our Coordinating Center (CC) draws heavily on established and emerging public health surveillance methods and integrates expertise from multiple disciplines.



Using novel surveillance to detect emerging drug trends

One aim of the new NDEWS is to incorporate and leverage novel surveillance methods to ensure early detection of signals of new and emerging drug trends, including data from "drug checking," an ongoing national venue-intercept study, our new Virtual HealthStreet, and the development of an innovative machine learning approach to detect emergence of new psychoactive substances in real-time through algorithms deployed to darknet drug markets and forums.

Novel Surveillance

NDEWS COVID-19 Response


Assessing the impact of the COVID-19 pandemic on drug overdoses and services utilization

NDEWS is conducting ongoing interviews with three key informant groups to understand the impact of COVID-19 on people who use drugs across all 18 Early Warning Network sites: emergency responders, workers at syringe exchange programs, and funeral directors. Findings will be rapidly disseminated to the scientific community and public.
