New Drug Test 'Paper' Uses Fingerprints To Detect Cocaine In Seconds

Police officers will now be able to tell if a person has used cocaine almost instantaneously with just a piece of paper and a fingerprint.
The paper which was developed by a team of researchers from the U.K. and The Netherlands can tell if someone has used the narcotic with 99 percent accuracy.
This procedure can be developed for other chemical materials too, and the team says it can be used as a highly accurate and safe method of running drug tests.
