When someone drives a vehicle while drunk there are plenty of road side tests that police can perform to confirm the drivers intoxication. For many other drugs, such as marijuana and cocaine, there are signs of intoxication, but no immediate method of proof. Often, urine or blood samples must be taken at the police station, which must then be processed to confirm the what and how much of the substance taken.

A new technology that analyzes the sweat from a person’s fingertips looks to revolutionize the drug testing market, providing on-site results in minutes with a test so advanced it can even detect marijuana intoxication.
