If you think you can fool a breathalyzer by downing a whole tin of Altoids, don't bother (we have friends who've tried). Besides, testing for alcohol levels by breath may soon be a thing of the past thanks to newer technologies.
Take this machine from a company called TruTouch Technologies, for example, which tests for blood alcohol by analyzing the skin and can yield results in 30 seconds. Uber Review says the technology uses "infrared reflectance spectroscopy," which we're all familiar with, of course.
Just don't mistake it for a toy cash register, or the results could be doubly embarrassing.
