You think popping a mint is going to help you? Think again. Swedish researchers announced Thursday that they were able to detect drugs like marijuana, cocaine, amphetamines and prescription pills simply by breathalyzing subjects.

The researchers recruited 47 subjects from a Stockholm drug emergency clinic, and used blood and urine samples as a baseline. All in all, the Swedish scientists were able to identify 12 different drugs using a cheap, commercial breathalyzer called SensAbues, that, humble brag, they made themselves.

What's more incredible is that the breathalyzer detected these drugs more than 24 hours after use. But the science is still imperfect and researchers also reported a 23 percent false positive rate. Plus, they ran into low detection rates with benzodiazepines, so it seems your Xanax is safe for now.
