Thanks for the info. Definitely something we have not run into or considered yet. I guess we just naively assumed that all police precincts were as scrupulous as those we talked to :(.

There is some stuff we can do, however. For instance, we can directly build the QC schedule into the device so it does not work unless you get it calibrated. We can also have QC cartridges that have a barcode that the device reads to make sure you actually ran a calibration check properly and the device passed.

We were so focused on internal methods for making the device accurate, but maybe we should put some thought into how we can make sure the police use it properly.

Bless your heart.

Really, if you're producing something that is reliably accurate, I would expect that would be all anyone would expect, along with proper training, verified updates, and audited software/firmware, etc. In the case I cited above it was more an issue with the lack of accuracy of the product, and sloppy follow through from the vendor, with money and political pressure thrown at the problem - something which the police departments themselves likely have less influence on anyway.

If your product is at all worthwhile, it will constantly be tossed back and forth between lawyers, trying to uphold or disprove its validity. ("Well here's an independent study done on how arresting officers with shaky hands get inconsistent results when administering the SannTek Cannibus test" et al et al ad nauseum) While yes, this is a problem in any society that applies capitalism principles to the practice of law.... I don't think there's necessarily a better system, sadly. Don't feel responsible to fix it all yourself. Anyway, pursue the technology as well as possible, by all means work in as many checks and balances as possible for correct use, and constant calibration, BUT ALSO talk and document openly during your design phase and testing the ideology you develop to govern false positives versus false negatives. This is an extremely engaging technology ethics discussion. If you drive the error to be false negatives, at a rate of 5%, will you not be able to sell it, because your customer is most interested in an effective tool? What is the societal benefit of getting this device to be accepted and used by the police? If you can achieve FN=4% is it worth it, or is the societal benefit actually much higher, possibly at FN =20%. Can you just run the test 5 times in a row, or with 2 stand alone devices to reach the dependability rate you desire? If you drive the error to be false positives, at a rate of 1%, can you sleep at night with the lives your product will effect, or do you need a fall back like your device determining with 100% accuracy that cannibus is present in someone's system (just not a definitive, exact amount), PLUS a statement from an arresting officer stating erratic or dangerous driving or behavior in conjunction with your device's input. I'm very excited about what you're doing. I didn't know (still not yet convinced) that the science is solvent, but I've been asking about this device for years.

Everyone says they are ethical including the unethical I'm not sure how you possibly took this at face value.
