In 2021, the Maryland Division of Well being and the state police have been confronting a disaster: Deadly drug overdoses within the state have been at an all-time excessive, and authorities didn’t know why. There was a normal sense that it had one thing to do with modifications within the provide of illicit medication—and particularly of the artificial opioid fentanyl, which has prompted overdose deaths within the US to roughly double over the previous decade, to greater than 100,000 per 12 months.
However Maryland officers have been flying blind when it got here to understanding these fluctuations in something near actual time. The US Drug Enforcement Administration reported on the purity of medicine recovered in enforcement operations, however the DEA’s knowledge provided restricted element and usually got here again six to 9 months after the seizures. By then, the precise medication on the road had morphed many instances over. A part of the investigative problem was that fentanyl might be some 50 instances stronger than heroin, and inhaling even a small quantity might be lethal. This made standard strategies of study, which required dealing with the contents of drug packages immediately, extremely dangerous.
Searching for solutions, Maryland officers turned to scientists on the Nationwide Institute of Requirements and Know-how, the nationwide metrology institute for the US, which defines and maintains requirements of measurement important to a variety of commercial sectors and well being and safety purposes.
There, a analysis chemist named Ed Sisco and his staff had developed strategies for detecting hint quantities of medicine, explosives, and different harmful supplies—methods that might defend legislation enforcement officers and others who needed to acquire these samples. Basically, Sisco’s lab had fine-tuned a expertise referred to as DART (for “direct evaluation in actual time”) mass spectrometry—which the US Transportation Safety Administration makes use of to check for explosives by swiping your hand—to allow the detection of even tiny traces of chemical substances collected from an investigation website. This meant that no one needed to open a bag or deal with unidentified powders; a usable residue pattern may very well be obtained by merely swiping the skin of the bag.
Sisco realized that first responders or volunteers at needle trade websites might use these similar strategies to securely acquire drug residue from baggage, drug paraphernalia, or used take a look at strips—which additionally meant they might now not want to attend for legislation enforcement to grab medication for testing. They may then safely mail the samples to NIST’s lab in Maryland and get outcomes again in as little as 24 hours, due to improvements in Sisco’s lab that shaved the time to generate a whole report from 10 to half-hour to only one or two. This was partly enabled by algorithms that allowed them to skip the time-consuming step of separating the compounds in a pattern earlier than operating an evaluation.
The Speedy Drug Evaluation and Analysis (RaDAR) program launched as a pilot in October 2021 and uncovered new, important info nearly instantly. Early evaluation discovered xylazine—a veterinary sedative that’s been related to grotesque wounds in customers—in about 80% of opioid samples they collected.
This was a major discovering, Sisco says: “Forensic labs care about issues which are unlawful, not issues that aren’t unlawful however do doubtlessly trigger hurt. Xylazine isn’t a scheduled compound, however it results in wounds that may result in amputation, and it makes the opposite medication extra harmful.” Along with the compounds which are identified to seem in excessive concentrations in road medication—xylazine, fentanyl, and the veterinary sedative medetomidine—NIST’s expertise can select hint quantities of dozens of adulterants that swirl by means of the street-drug provide and may make it extra harmful, together with acetaminophen, rat poison, and native anesthetics like lidocaine.
What’s extra, the precise chemical formulation of fentanyl on the road is at all times altering, and variations in molecular construction could make the medication deadlier. So Sisco’s staff has developed new strategies for recognizing these “analogues”—compounds that resemble identified chemical buildings of fentanyl and associated medication.

The RaDAR program has expanded to work with companions in public well being, metropolis and state legislation enforcement, forensic science, and customs companies at about 65 websites in 14 states. Sisco’s lab processes 700 to 1,000 samples a month. About 85% come from public well being organizations that target hurt discount (an method to minimizing unfavorable impacts of drug use for people who find themselves not able to stop). Outcomes are shared at these assortment factors, which additionally acquire survey knowledge in regards to the results of the medication.
Jason Bienert, a wound-care nurse at Johns Hopkins who previously volunteered with a nonprofit hurt discount group in rural northern Maryland, began taking part within the RaDAR program in spring 2024. “Xylazine hit like a storm right here,” he says. “Everybody I took care of wished to know what was of their medication as a result of they wished to know if there was xylazine in it.” When the information began coming again, he says, “it nearly grew to become a race to see what number of samples we might acquire.” Bienert despatched in about 14 samples weekly and created a chart on a dry-erase board, with medication recognized by the logos on their baggage, sorted into columns based on the compounds present in them: heroin, fentanyl, xylazine, and every part else.
“It was a brilliant useful gizmo,” Bienert says. “Everybody accepted the validity of it.” As folks got here again to examine on the outcomes of testing, he was in a position to construct rapport and supply extra assist, together with offering wound take care of about 50 folks per week.
The breadth and depth of testing beneath the RaDAR program enable an eagle’s-eye view of the nationwide street-drug panorama—and insights about drug trafficking. “We’re seeing distinct fingerprints from completely different states,” says Sisco. NIST’s evaluation reveals that fentanyl has taken over the opioid market—apart from pockets within the Southwest, there may be little or no heroin on the streets anymore. However the fentanyl provide varies dramatically as you cross the US. “If you happen to drill down within the states,” says Sisco, “you additionally see completely different fingerprints in numerous areas.” Maryland, for instance, has two distinct fentanyl provides—one with xylazine and one with out.
In summer season 2024, RaDAR evaluation detected one thing actually uncommon: the sudden look of an industrial-grade chemical referred to as BTMPS, which is used to protect plastic, in drug samples nationwide. Within the human physique, BTMPS acts as a calcium channel blocker, which lowers blood stress, and combined with xylazine or medetomidine, could make overdoses more durable to deal with. Precisely why and the way BTMPS confirmed up within the drug provide isn’t clear, however it continues to be present in fentanyl samples at a sustained degree because it was initially detected. “This was an instance of a compound we might have by no means thought to search for,” says Sisco.
To Sisco, Bienert, and others engaged on the general public well being entrance of the drug disaster, the ever-shifting chemical composition of the street-drug provide speaks to the futility of the “warfare on medication.” They level out {that a} crackdown on heroin smuggling is what gave rise to fentanyl. And NIST’s knowledge reveals how in June 2024—the month after Pennsylvania governor Josh Shapiro signed a invoice to make possession of xylazine unlawful in his state—it was nearly totally changed on the East Coast by the following veterinary drug, medetomidine.
Over the previous 12 months, for causes that aren’t absolutely understood, drug overdose deaths nationally have been falling for the primary time in a long time. One concept is that xylazine has longer-lasting results than fentanyl, which suggests folks utilizing medication are taking them much less typically. Or it may very well be that extra and higher details about the medication themselves helps folks make safer choices.
“It’s troublesome to say this system prevents overdoses and saves lives,” says Sisco. “Nevertheless it will increase the chance of individuals coming in to needle trade facilities and getting extra linkages to wound care, different companies, different training.” Working with public well being companions “has humanized this whole space for me,” he says. “There’s much more grey than you assume—it’s not black and white. And it’s a matter of life or dying for a few of these folks.”
