of the three fails, the first two dont shock me so much. they have such a small amount in the first place, i would imagine that a fail in a test like this could be a combination of 1% margin of error in either side (making the product or testing it) and some bad luck...but that last one is supposed to be 1000mg and came out at 0mg
did someone mix up the samples at the lab? lol thats shameful.
with flower (and the extracts made from it) there can be some variation in %s, so that is to be expected from products using that as a base. testing is expensive (it was around $150 per sample for me a couple years ago) so its possible that a big company with lots of products and batches being made doesnt test (or doesnt have to test, it would be interesting to see the actual regulations they have to follow) every single thing. it actually makes sense because they have to print so much packaging and stuff that they prolly just get the first batch tested and then print the packages with that info forever (or until they re-test it if they have to do it semi-regularly).
the problem with that argument is that most of these cbd products are made with isolate, which is 99% pure every time and should be foolproof to measure correctly
