How about everyone bring it down a notch.
Everybody knows lab test results have a margin of error as much as ±10%. Oregon actually allows up to 20% RSD between duplicate tests. So nobody can make a statement that their material is 99.9% in an absolute sense; they aren’t accurate enough to make any conclusion on whether there’s 1% contaminate or 0.1% contaminant, and what the color of that contaminant may be.
That said, a 99.9% test result is great. That’s as good a test result as anyone can possibly be expected to give with these testing variances and it’s a testimony to quality.
It may be possible that a true 99.9% cannabinoid distillate would be as colorless as Beaker’s oil here. Or it might not be the case. Nobody can make that determination based only on these cannabis lab tests. It would require much more sensitive tests to actually determine the amount of non-cannabinoids and their identities.
