I highly doubt your users will give a shit what the THC content is.
THIS. I am not AT ALL persuaded that THC contributes a whole lot beyond red eyes, dry mouth, the munchies, etc. Marinol users report NOT getting high and don’t really rate it a pleasant experience (link me if I’m wrong).
I was getting blissfully high long before anyone heard of THC, and I’m a real fan of landraces/old-fashioned weed & hash. I’ve been of the opinion since the 70s that the high, the use experience, is a full-spectrum phenomenon (yes, that *does* mean I’ve gotten high smoking stems (more than once)) - that it takes ALL the instruments, so to speak.
In all seriousness: when testing revealed that THC produced *OBSERVABLE PHYSICAL SIGNS OF EFFECT*, that was an answer to law enforcement prayers. Now, an officer could decide someone *looked* like they were using marijuana...and THC could be tested for in urine. I’m sure we all know where that went. For one thing, it quickly became universally acknowledged that “THC gets you high”, even though all they needed was a testable component that came along with getting high. That’s a far cry from *proving* that THC produces more than just the most obvious visible side effects...and AFAIK it *still* hasn’t been proved that THC is THE essential element to the experience of being cannabinized.

This doesn’t mean nothing *could* be gained by a testing device like this, but we still don’t know enough to even play with the numbers it would produce - or at least I don’t...but I’m here to learn
