Police scrapping drug field tests over safety

ST. LOUIS

Police who find suspected drugs during a traffic stop or an arrest usually pause to perform a simple task: They place some of the material in a vial filled with liquid. If the liquid turns a certain color, it’s supposed to confirm the presence of cocaine, heroin or other narcotics.

These chemical field tests have been standard procedure for decades, with officers across the country using them every day. Prosecutors rely on the results to jail suspects and file criminal charges.

But some large law- enforcement agencies have recently abandoned the routine tests out of concern that officers could be exposed to opioids that can be absorbed through the skin or inhaled. Even a minute amount of the most potent drugs, such as fentanyl, can cause violent illness or death.

Police are instead sending suspected drugs to crime laboratories, which have quickly become over-burdened, delaying many cases.

“We instituted the precautions for self-preservation, frankly,” said James Shroba, the agent in charge of the Drug Enforcement Administration office in St. Louis. Agents, he said, began finding fentanyl in everything they seized, including marijuana, cocaine and methamphetamine.

Over the past 18 months, field testing has been banned by the DEA, state police in Oregon, Arizona, Michigan and Missouri, and several big-city departments, including New York and Houston.

No police deaths have been blamed on fentanyl, a synthetic opioid developed for cancer patients and others suffering severe pain. But dozens of officers have become ill, including 18 in one raid last year in Pittsburgh.

Illegal, raw fentanyl powder can be 50 times more potent than heroin and is often mixed with other street drugs. Synthetic drugs were blamed for more than 20,000 U.S. overdose deaths in 2016 – double the number from 2015. Prince and Tom Petty are among its victims.

The field test provides only a preliminary finding that must be confirmed by a lab. In fact, a 2016 New York Times report called into question the accuracy of field tests, saying they often produce false positives.

Still, field test results often convince suspects to plead guilty even before the initial indications are checked by scientists, prosecutors said.

For cases that go to trial, full lab results can take months, which puts some suspects back on the streets for long periods.
