OAKLAND, CALIFORNIA — A breathalyzer to help law enforcement police marijuana smoking drivers is being tested in California. <br /> <br />The marijuana breathalyzer, named The Hound, is put to use when a police officer pulls over a driver who is observed to be driving erratically. <br /> <br />The driver blows into a tube in the device, twice and indicates that it has enough breath for testing purposes. A chemical analysis then locates and isolate the THC molecules in the sample. Once the process is complete, the test results —THC levels measured in parts per trillion or picograms — are displayed on the screen. <br /> <br />Drivers tested in California were not arrested or charged, but those who did test positive for THC were not allowed to continue driving, reported RT. <br /> <br />Hound Labs, the company behind the device, is aiming to distribute the devices to law enforcement across the U.S. during the first half of 2017.
