Scientists design a 5 minute test to detect cocaine and marijuana use

The Vantix biosensor, designed by Cambridge-based Universal Sensors is a quick, accurate, and inexpensive technology
that can allegedly measure microscopic residue of marijuana and cocaine in saliva [mixture of water, protein, and salts that makes food easy to swallow; begins digestion] within a few minutes.

The device could also aid the police around the country to perform roadside tests on drivers suspected of driving while under the influence of drugs.

The company's Commercial Director, Kevin Auton stated, "In America, parents are taking samples of their children's saliva and hair and sending them off to labs to see if their children are taking drugs. If there is demand for it here, it would be an interesting market."

"It is controversial but the test can be used in the home for worried parents to test if their children are taking drugs. We are very focused on getting the test out of the laboratory and on to other platforms. It is as simple to use as a pregnancy test."
