Pot BreathalyzerA California lab is creating a bit of a buzz thanks to a new product aimed at people dabbling in what is now a legal pastime. Matt Francis, a chemist at the University of California, Berkeley has spent the past 18 months developing what is being called a pot breathalyzer. Francis says THC, the chemical in marijuana that makes people high can linger in bodies for days and even a month. So if a police officer pulls someone over and suspects they are driving while high the current blood and urine tests are not conclusive. So while it’s easier to make the arrest, getting the conviction is a harder battle to win. Now thanks to this device, officers will be able to tell if someone has smoked pot within the past couple hours. Francis says someone’s breath is a much better indicator of how recently they have smoked, just like it’s a strong indicator of how much they have had to drink. So his device, not only detects pot smoke but alcohol levels as well. The Š—“but I didn’t inhale” excuse might not work here.
