Yes! There has been interest from safety-sensitive industries such as transportation, energy, manufacturing, construction, and oil & gas to use our device to help prevent life-threatening accidents in the workplace.
Let's modify the above somewhat: Have you considered not selling to cops in places where marijuana use is illegal? You have a nice traffic safety story for Canada, but aren't you afraid that in the US police will just "randomly" stop and test people (anywhere, not just drivers) they would like to incriminate?
Wouldn't the companies be benefited by using blood tests since they will return positive after longer periods of time? Basically, don't blood tests allow companies to say "sorry no workers compensation - you were high when that beam cut off your leg"?
But also, I have mixed feelings about this from a moral/ethics perspective. I think it's going to do more harm than good by making testing easier and more prevalent (we already have blood tests for cases where someone was injured by a driver, etc.). The good thing is it may save some regular users from being labeled as impaired versus a blood test. Outside of that small case it all seems bad for society to me..
