New Marijuana Breathalyzer Technology On The Way?

Researchers from the University of Pittsburgh have developed a brand new THC breathalyzer, however does it have real-world utility?

Throughout the legalization motion, a rising concern has been marijuana customers whereas excessive. This shouldn’t be an alarmist fear, both. One poll found that greater than half of routine hashish customers consider they will drive whereas stoned. In addition, a study released by AAA reported that greater than 15 million Americans have gotten behind the wheel of a automotive inside an hour of smoking hashish.

As extra states legalize hashish within the coming years, this may solely change into extra of a urgent problem for legislation enforcement. While police have had know-how to measure lawful blood-alcohol ranges of drivers for years, the identical can’t be stated for quantifying THC ranges. (THC is the cannabinoid in marijuana that induces psychoactive sensations in customers.) But in response to the growing want, scientists have been arduous at work to develop a so-called marijuana breathalyzer.

Tech firms in California and Canada have each raised important funding to get their very own marijuana breathalyzers off the bottom in latest weeks. But it’s been researchers from the University of Pittsburgh accountable for developing and patenting a working THC breathalyzer. Using nanotechnology, a presumably intoxicated will blow into the machine. Then, these air molecules will bind with carbon tubes 100,000 occasions smaller than a human hair, which can successfully determine the extent of THC molecules.

“We used machine studying to ‘teach’ the breathalyzer to acknowledge the presence of THC primarily based on {the electrical} present’s restoration time, even when there are different substances, like alcohol, current in the breath,” Sean Hwang, a Pitt doctoral candidate in chemistry and lead writer of a written report of the machine within the journal ACS Sensor, stated in a press launch.
