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..
Have you considered respecting the professionals who keep us safe, and not assuming that they're all somehow bad people out to get good folks who just happen to be "in the wrong place at the wrong time"?
Why do you think this? Do you know many police officers, or are you operating off of narratives you've absorbed from elsewhere?
You'll note that most people angrily report their bad incidents with cops; when they're doing their job it goes unremarked. Not too far off from good IT support.
It's an opinion built up over repeated interactions with police. Of course the Yelp effect applies to police but even my positive interactions with police have left me with an impression that public safety and in some respects law enforcement itself is not their primary motivation for being police. In the absence of a comprehensive psychological analysis covering a geographically distributed sample of police with a large sample size, my own experiences are what I fall back on to form my opinions. YMMV.
