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.
