Convinced that breathalyzer tests can only determine how drunk you are? Wrong. Last week, a group of analysts in Sweden announced that breathalyzers were able to sense the presence of cocaine, marijuana, prescription pills and amphetamines. Researchers visited a clinic in Stockholm to gather samples, and were able to detect 12 different types of drugs using a basic breathalyzer known as a SensAbues.

These devices, which the resources created, move fast—they were able to pick up on the drugs a mere 24 hours after use. Before you start rejoicing or panicking, keep in mind that a 23 percent false positives rate was also reported.
