Estimated Population Served: 15,600 Summary of findings (January 8 – March 12, 2026):
Cocaine (parent) / Benzoylecgonine (metabolite): Parent and metabolite average concentrations decreased in January but then began to trend upwards in mid-February. Both the parent and metabolite average concentrations remained below regional and national detections. Benzoylecgonine had overall higher average concentrations compared to cocaine. Fentanyl (parent) / Norfentanyl (metabolite): Parent and metabolite average concentrations have steadily increased since the end of January. Concentrations remained below regional and national averages, until mid-march when the average fentanyl concentration exceeded the regional average. Methamphetamine (parent) / Amphetamine (metabolite): Parent and metabolite concentrations remained relatively steady with concentrations below regional and national averages until beginning to increase at the end of February and slightly surpassing the national average. Methamphetamine had overall average concentrations higher than amphetamine. Xylazine (parent) / 4-Hydroxyxylazine (metabolite): Parent concentrations remained relatively stable from the beginning of January to the end of February before beginning to steadily increase and surpass the national average, while remaining below the regional average. Metabolite concentrations were not detected. Trans-3’-Hydroxycotinine (metabolite of nicotine): Average concentrations of Trans-3’-Hydroxycotinine have increased in March, remaining below the national average but above the regional average.
