Police and employers in states with legal cannabis or hemp have been dealing with the burden of determining who is too impaired to drive or work based on standard sobriety tests. Without analysis, cannabis and hemp flowers appear the same but their psychoactive effects differ greatly. 

Hound Labs has developed a breathalyzer that can detect acute use of alcohol or cannabis by detecting alcohol and psychoactive cannabinoids in the breath. Hound Labs was recently awarded another patent (US Pat. No. 10,641,783) for their breathalyzer technology bringing their IP portfolio to over 10 US patents and patent applications.
