A groundbreaking new fingerprint drug testing system can detect the presence of cannabis and other drugs with up to 99 percent accuracy, according to a study published recently in the Journal of Analytical Toxicology. The device, the Reader 1000 manufactured by U.K. firm Intelligent Fingerprinting, can detect four classes of commonly abused drugs in the trace amounts of sweat found in fingerprints.
The Reader 1000 analyzes the sweat in the fingerprints of subjects, living or dead, for cannabis, amphetamines, opiates, and cocaine and delivers results within ten minutes. The accuracy of the device was found to be 99 percent for cannabis, 95 percent for cocaine, 96 percent for opiates, and 93 percent for amphetamines. The Reader 1000 consists of a portable analysis unit and a cartridge to collect the fingerprint sample. When the cartridge with the sample is inserted into the analysis unit, sensors detect the presence or absence of metabolites of the four drug classes.
