Orlando police pulled over a man and arrested him for drug possession. But it turns out that drug was a Krispy Kreme doughnut.

After being pulled over for failing to come to a full stop before driving out of a parking lot, 64-year-old Daniel Rushing told the Orlando Sentinel he was arrested, jailed and strip-searched — all over a few flakes of sugar in his car. Police thought the flakes were crystal methamphetamine.

“I kept telling them, ‘That’s … glaze from a doughnut,” he told the Sentinel. “They tried to say it was crack cocaine at first, then they said, ‘No, it’s meth, crystal meth.’”

But two roadside drug tests came back positive for meth. Rushing, who is white, ended up spending 10 hours in jail and was released on a $2,500 bond. Prosecutors later dropped the case against him after another test determined the flakes were not an illegal drug.

It may come as a surprise to some that a seemingly impartial drug test could incriminate Rushing for eating a doughnut, but it’s actually quite common. Many of the cheapest — and therefore most popular — roadside tests are intrinsically flawed. As a ProPublica investigation from July noted, the chemicals used in some tests will react to some acne medications and common household cleaners the same way it does to cocaine. Other tests are susceptible to hot or cold weather. Officers are also not always sure how to use or read the results.

Yet these tests are used to arrest more than a million people every year. The Orlando Police Department told the Sentinel they have no way to track field drug tests, but Florida seems to mess them up often. In ProPublica’s review of the Florida Department of Law Enforcement’s lab system, they found that 21 percent of evidence police listed as meth was not actually meth. Half of those substances were not even an illegal drug. ProPublica also found that one sheriff’s department in Florida had registered 15 false positives for meth in a span of seven months.

Rushing plans to file a lawsuit for the arrest, which the Orlando police are still categorizing as lawful, next month.
