OHIO – A new breakthrough on detection devices could give police a new piece of equipment for fighting under the influence drivers.
Researchers at University of Pittsburgh chemistry and engineering departments are working on a device to measure the amount of tetrahydrocannabinol or THC in a user’s breath.
Research recently published says the new device can detect THC from other compounds found on breath such as CO2, water, ethanol, methanol, and acetone. Machine learning algorithms were utilized to improve the selective detection of THC with better accuracy at increasing quantities of THC delivered to the chemiresistor.
Not ready for police use, but the system is patented and could be available to law enforcement in the near future.
