That depends on how the research and regulation surrounding cannabis shake down.
Right now, our device would just be used as a screen to see if someone had used the drug recently. The device's results would not be taken to court and would likely be followed up with a blood or urine tests (not ideal, but that is what the courts accept these days).
Our device has the capacity to output a concentration, but more research into THC content in breath and impairment needs to be done to see if that concentration means anything. Likely, if a link between breath concentration and impairment is established, there will be a statutory concentration set for cannabis.
