Summary
This study tests if a harmless dye (fluorescein sodium) added to a drink can confirm that a urine sample is authentic and not tampered with. About 114 adults with substance use disorder will drink either a marked or unmarked beverage, then provide a urine sample 15 minutes later. The goal is to improve the accuracy of drug testing by detecting fake samples.
