Researches create breathalyzer that can detect marijuana

Researches at the University of Pittsburgh are working to develop a marijuana breathalyzer that can be used by law enforcement in the field.

According to WKBN in Pittsburgh, Pa., a team from the university’s chemistry and engineering departments are working on a device to measure the amount of tetrahydrocannabinol or THC in a user’s breath.

Reports show the device is able to differentiate THC from other compounds found in breath such as CO2, water, ethanol, methanol, and acetone.

The machine’s algorithms are utilized to improve the selective detection of THC with better accuracy at increasing quantities of THC.

WKBN reports the machine is not available commercially yet but is patented and could be available soon for law enforcement.
