A new breathalyzer is in development to detect weed, according to USA Today.
The new breathalyzer is reportedly being rolled out in select cities this upcoming fall. Hound Labs describes the new breathalyzers as being “hypersensitive” saying: “The Hound breathalyzer is 1 billion times more sensitive than today’s alcohol breathalyzers.”
How is works is when someone blows into the device, it can detect alcohol, THC, or both in only minutes. From there, the device will display "warning" or "pass".
