It’s generally understood that driving while under the influence of many substances can greatly increase the chance of getting in an accident. As such, it’s common for police officers to use a breathalyzer to check someone’s blood alcohol content, to ensure that they aren’t impaired. Unfortunately, alcohol is one of the only substances that they can check for, and receive immediate results. But that looks to be changing soon.

A company called Intelligent Fingerprinting has just unveiled a prototype hand-held drug testing device that can provide officers with immediate results. The company hasn’t released information on exactly what substances are they are able to test for, but we do know that the process involves little more than having your fingerprint scanned by the device. We should know more when the device is put into production sometime next year.
