Canada's Cannabix Technologies closing in on pot breathalyzer to detect DUI

Canada's Cannabix Technologies says it has developed a handheld prototype of a "pot breathalyzer" to detect drivers who are high, akin to those used to test for drunken driving. "I think the first breathalyzer on the market will be a simple 'yes' or 'no' for the presence of THC at the time of the test, and in that sense it won't provide a quantitative evidential measure," said Barry Knott, the CEO of Lifeloc, which is also scrambling to make such a device.
