Each month, NDEWS Sentinel Site Directors report on the current landscape of drug use in their communities through quantitative and qualitative data. Trends include data on drug seizures, laboratory testing, community drug checking, novel psychoactive substances, and overdoses (fatal and nonfatal). Continuous integration of these reports ensures NDEWS can issue timely public health alerts and adapt strategies to minimize harms as trends evolve.
