RE:A THC Breathalyzer is a must!Agree. And Hound Labs is: 1) ahead of Cannabix on development, 2) is based in California, 3) has private backing, 4) has a solution that will be good enough for law enforcement to use, 5) will be ~$500 to purchase. My concerns with Cannabix have yet to be addressed so I will stay away. Purely a speculative stock.
