Pot Breathalyzer Is Still a Police Pipe Dream
New Swedish device detects marijuana on a driver's breath—but it probably won't help law enforcement much.
As 4:20 threatens to become as popular as happy hour, police are scrambling to figure out a reliable way to make sure that the dude who's zoning out in the Taco Bell drive-thru isn't too stoned to drive. The problem is, roadside breathalyzer tests administered to drunks don't work for pot smokers, forcing cops to take suspected stoners into the station for a blood test. Now the Swedish company SensAbues is offering something of a fix. A study published in the Journal of Breath Research last week found that its proprietary breath-testing device can detect recent use of a wide range of drugs, including prescription meds, cocaine, and marijuana.
