The number of nitazene analog reports submitted to the National Forensic Laboratory Information System jumped from 43 in 2019 to 1,905 in 2024, a study analyzing NFLIS data found. Counts rose sharply between 2019 and 2021 before stabilizing, with the composition shifting from predominantly isotonitazene to metonitazene and protonitazene making up nearly 60 percent combined in 2024. Ohio and Tennessee recorded some of the earliest nitazene-related fatalities, according to the research published in a scientific journal.
DEA TOX received and analyzed samples from multiple states in the second quarter of 2026, identifying 291 detections of novel psychoactive substances across 34 analytes. Of the 166 cases examined that quarter, nearly half involved at least one NPS analyte while 30.7 percent involved fentanyl, the DEA TOX 2026 Q2 Report stated. The agency placed many of these substances in the NPS category as they lack FDA approval for medical use in the United States.
A new synthetic opioid called cychlorphine has emerged as a significant concern, with the Office of National Drug Control Policy reporting at least 55 deaths linked to it between 2025 and early 2026. Tennessee recorded 63 deaths associated with the drug from July 2025 to September 2026, according to the Knox County Regional Forensic Center. The DEA placed cychlorphine into Schedule I in August 2025, classifying it as having high abuse potential with no accepted medical use.
Provisional CDC data through October 2026 shows drug overdose deaths involving synthetic opioids remaining a primary driver of the national total, even as overall fatalities have declined from previous peaks. Methamphetamine-involved deaths rose to 37,096 in 2024, bucking the downward trend in fentanyl-related fatalities that year, an analysis of CDC NVSS data indicated. The divergence highlights the evolving nature of the polysubstance crisis.
Domestic production has increased as traffickers adapt to international controls, with the DEA noting detections of clandestine laboratories manufacturing these synthetics in several states. Florida laboratories have identified multiple nitazene compounds, accounting for the highest number of exhibits for metonitazene and protonitazene, DEA figures show. Chemical suppliers in China continue to ship precursors, but domestic mixing and tableting operations have expanded the reach of these homemade variants.
The DEA launched the Fentanyl Free America initiative in December 2025 to combat synthetic drug supply through enforcement and awareness, the agency said in a statement. As part of the effort, the DEA seized more than 45 million fentanyl pills and 9,320 pounds of powder by late 2025, removing an estimated 347 million potentially deadly doses. Laboratory testing showed a reduction in the potency of seized pills, correlating with declining synthetic opioid death rates to levels not seen since 2020.
Experts have warned that the rapid emergence of new analogs outpaces regulatory responses, with 22 nitazene molecules identified by the end of 2024 according to forensic researchers. The New York Times reported on the fast-changing chemistry of these drugs, noting how illicit chemists tweak structures to evade bans. China banned nitazenes in July 2025, potentially shifting production to other regions, the newspaper added.
