The Colorimetric Presumptive Field Drug Test Limitations Act

Summary

This model seeks to limit the harm enabled by error-prone colorimetric field drug tests. The widespread use of presumptive field drug test kits is generating tens of thousands of wrongful arrests in which innocuous substances are misidentified as illegal drugs, leading to the conviction of innocent people. While there have been many reports of errors with field drug test kits over the years, the extent and scale of their impact has only recently been quantified. In January of 2024, a national study released by the Quattrone Center for the Fair Administration of Justice at the University of Pennsylvania Carey Law School, found that tests like these – presumptive, colorimetric drug tests used in the field vs. controlled tests in a crime lab – are used in approximately half of America’s 1.5 million drug arrests, and in 30,000 of these arrests innocent people are wrongfully implicated by false positives from these colorimetric tests. As a result, it appears that plea agreements based on these error-prone drug tests are the single largest known cause of wrongful convictions in the United States.
