Estimated Population Served: 7,000 Summary of findings (July 22 – September 30, 2025): Cocaine (parent) / Benzoylecgonine (metabolite): Parent and metabolite concentrations fluctuated but generally remained above national and regional averages, expect in mid-August where both had a drop in detections. Benzoylecgonine had overall higher concentrations compared to cocaine. Fentanyl (parent) / Norfentanyl (metabolite): Irregular patterns were reported for parent and metabolite concentrations but generally remained below regional and national averages, except for an uptick in fentanyl at the beginning of September. Methamphetamine (parent) / Amphetamine (metabolite): Parent and metabolite concentrations remained relatively steady with concentrations below regional and national averages. Xylazine (parent) / 4-Hydroxyxylazine (metabolite): Xylazine was detected once in mid-September and there were no detections of 4-Hydroxyxylazine. Trans-3’-Hydroxycotinine (metabolite of nicotine): Trans-3’-Hydroxycotinine fluctuated but remained roughly around regional and national averages.
