So with all the growers in OK, legal and less so, is there any effort to evaluate the product by the govt or any "authority" they may have created for that purpose? In Illinois, for example, where the law was designed to have very close control by an agency empowered by the state govt to protect the consumer, all the cannabis in all of it's (legal) forms must be inspected for mold and pesticides and content (thc, cbd, etc). I will attach what a label looks like here as an example. The first one is from concentrate and the second is from some gummies (that I haven't tried yet).
My guess is that even if an organization to check the "purity" of product exists in OK, it would be overwhelmed by the sheer number of growers and product in the market.
I have thought about this often but not yet acted. I don't really know how your pricing is, and I'm sure it isn't like OK, but it is very likely to be better than ours...
