Fluorofentanyl Surge in Eastern Seaboard
para-Fluorofentanyl detections increased 340% quarter-over-quarter across Subcheck client programs in the NE corridor. Now the second most common analog after fentanyl itself in NY, NJ, PA, and MD.
Nitazene Class Emergence in Midwest
Isotonitazene and metonitazene detected for the first time in community-level Subcheck testing across OH, MI, IN, and WI. Nitazenes are non-fentanyl synthetic opioids with potency comparable to or exceeding fentanyl.
Orphines: A New Synthetic Opioid Class Emerges
Orphines (benzimidazol-2-ones) — a structurally novel class of synthetic opioids distinct from both fentanyl and nitazenes — have been identified in 12+ US states. Unlike nitazenes, orphines are completely undetectable by all currently available rapid immunoassay test strips, including fentanyl, nitazene, and opioid panels.
Xylazine Contamination Rates Stabilizing
After rapid expansion in 2023-2024, xylazine co-contamination rates appear to be stabilizing at ~35% of fentanyl-positive samples nationally. Regional variation remains significant.
Stimulant Supply Contamination Expanding
Fentanyl contamination of methamphetamine and cocaine supply continues expanding. 18% of Subcheck positive detections in CA, AZ, NV, and CO came from users testing stimulant samples.
