Estimated Population Served: 15,600 Summary of findings (March 5 – April 29, 2026): Cocaine (parent) / Benzoylecgonine (metabolite): Parent and metabolite average concentrations trended upwards in March before they declined. Parent average concentrations remained below national and regional detections, while the metabolite average concentrations surpassed national and/or regional detections from mid-March to early April. Benzoylecgonine had overall higher average concentrations compared to cocaine. Fentanyl (parent) / Norfentanyl (metabolite): Parent average concentrations have decreased since mid-March and then began to rise again in late April. Metabolite concentrations have remained relatively stable. Concentrations remained below regional and national averages except during mid-March when the average parent concentration exceeded the regional average. Methamphetamine (parent) / Amphetamine (metabolite): Parent average concentrations remained relatively steady with concentrations below the national averages and in-line with regional averages. Metabolite average concentrations declined in mid-March slightly increasing in the beginning of April. Metabolite concentrations were below national and regional averages except during March. Methamphetamine had overall average concentrations higher than amphetamine. Xylazine (parent) / 4-Hydroxyxylazine (metabolite): Parent average concentrations show a decline and eventual non‑detection from the end of March onward. These concentrations stayed below the national average except during the first-half of March and remained below the regional average. Metabolite concentrations were not detected. Trans-3’-Hydroxycotinine (metabolite of nicotine): Average concentrations of Trans-3'-Hydroxycotinine sharply decreased from March into early April before beginning to rise again in late April. During this decline, concentrations remained above the regional average until early April but stayed below the national average throughout the entire period.
