Document Category: Field Drug Test

This motion seeks discovery concerning the reliability of colorimetric presumptive field drug tests, arguing that these tests are unreliable and prone to high false-positive rates. Drawing on empirical research and audits from jurisdictions nationwide, the motion explains that common legal substances frequently trigger positive results and that accuracy varies widely based on officer training, storage, and administration. It argues that information regarding test methodology, error rates, officer training, and agency policies constitutes Brady and Giglio material and is essential for effective assistance of counsel at the plea-bargaining stage and knowing pleas. Defenders can use this motion to compel early discovery.
