A paper-based electrochemical device made from watercolor paper, graphite pencil, and silver paint can detect lysergic acid diethylamide (LSD) in seized samples. The device uses square wave voltammetry and achieves detection and quantification limits of 0.38 and 1.27 μmol/L, respectively. Its performance matches that of a commercial screen-printed carbon electrode, and it successfully distinguished LSD from MDMA and methamphetamine. Recovery from seized samples was less than 10%. The approach offers a low-cost, portable alternative for forensic drug analysis.
