About 20 percent of the marijuana products in California that have been checked since the state began mandating quality tests on pot goods this summer have failed those trials for purity and potency, the Associated Press reports. Candies, tinctures, and cannabis-infused cookies have been especially hard-hit by the checks, resulting in about one-third being kept from hitting dispensary shelves. Some of the tests, which began July 1, found incorrectly labeled products with the wrong potency described—a problem that can easily be corrected. In other cases, the products had unacceptable levels of pesticides or bacteria and were ordered to be destroyed.
