This is a test for detecting and identifying illicit substances. The surface test includes two test papers and a liquid ampule which is capable of detecting over twenty different drugs. By rubbing the enclosed test paper over the suspect area or substance and dripping a small amount of liquid from the ampule, the test paper will change color indicating what drug has been identified. The best thing about this test is, even if there are no signs of a drug, it is still possible to detect its presence.
