Roadside Drug Tests Are Sending Innocent People to Jail. Colorado Needs to Fix This.

A Stout Law client recently made the news for something no one should have to face: being charged with cocaine possession based on a roadside drug test that she says produced a false positive. CBS Colorado covered her story. She's a disabled grandmother who was pulled over, tested with a colorimetric field kit, and charged with a felony. The test said cocaine. She says it wasn't.

Her case isn't an outlier. It's a systemic problem.

The Science (and the Problem)

Colorimetric field test kits work by mixing a substance with a chemical reagent and looking for a color change. The problem is that dozens of common household substances produce the same reaction as cocaine. Baking soda. Chocolate. Certain medications. The kits have a documented false positive rate that forensic scientists have criticized for years, and yet they're still being used as the basis for felony charges across Colorado.

A positive field test result doesn't mean someone possessed drugs. It means a street-level screening suggested a possibility. Lab confirmation is what actually determines the truth. But by the time lab results come back, a person may have already been arrested, jailed, lost their job, or taken a plea deal just to get out of the system.

What Colorado Law Currently Says

Under current Colorado law, field test results can support probable cause for an arrest. That's a low bar by design. But the problem is that cases are sometimes built around those results, and defendants face pressure to resolve charges before the state crime lab ever confirms whether the substance was actually illegal. This can mean months in legal limbo, racked up attorney's fees, and a record for something that didn't happen.

The Legislative Push for Reform

Colorado legislators have introduced bills in recent sessions aimed at limiting reliance on field drug tests in criminal prosecutions. The core proposals focus on requiring lab confirmation before charges can be formally filed, and giving defendants a clearer path to dismissal when lab results come back negative or inconclusive. These reforms are reasonable, overdue, and supported by basic due process principles.

Defense attorneys around the state have been pushing for these changes for years. The argument isn't that drug crimes don't happen, it's that we shouldn't be able to take someone's liberty based on a test that experts know is unreliable. That's not a criminal defense position. It's basic constitutional law.

What to Do If You're Facing a Drug Charge Based on a Field Test

If you or someone you know has been charged with drug possession following a roadside field test, don't assume the charge will stick. The first step is demanding lab confirmation. A good defense attorney will push for that immediately and, in the meantime, challenge the reliability of the field test as a basis for continued prosecution.

These cases require aggressive early intervention. Plea deals made before lab results return are often very hard to undo. Don't wait.
