How come these local dispensaries don't test for mold and other toxins?

Im looking at WNC CBD, Apothica, and Franny's and noticed that none of them post test results for microbials, pesticides, fungicides, growth regulators, herbicides, mycotoxins or heavy metals. I also noticed they don't show test results for residual solvents. Is there just no standard for testing in NC? Just test for cannabinoids and terpenes and it's "safe"?'
