Faulty drug tests deployed by law enforcement continue to ruin lives. Usually, it's cheap field tests used by officers during traffic stops that turn legal substances into illegal substances, resulting in hefty criminal charges for people who've never used drugs, much less carried them around in their cars.

The current faulty drug test debacle isn't likely to generate as much sympathy or result in wide-ranging investigations of drug testing tech. These drug tests are negatively affecting people who are already locked up, which isn't quite as disturbing as minor moving violations escalating into felony drug charges.
