Testing

Officials with the Oklahoma Medical Marijuana Authority are opening a testing lab that will perform its own testing of medical cannabis products, double-checking the results from the state’s commercial testers.

USDA officials last week delayed the enforcement of a rule requiring consumer hemp products to be tested by labs registered with the DEA; it’s the third year in a row that officials have delayed enforcing the rule.

California this week ordered product recalls for five licensed cannabis products including four vape pens and a vape cartridge due to contamination with chlorfenapyr, which is a banned pesticide.

Many of California’s cannabis testing labs are currently not allowed to test the potency of flower products due to a rule change designed to combat so-called “lab shopping” in the state.

Starting this year, the Oklahoma Medical Marijuana Authority will be utilizing “secret shoppers” in its effort to regulate the industry. Under the new law, regulators will anonymously purchase products and have them tested by a lab.

In a move that highlights the controversy around potency obsession and lab-shopping, Washington state regulators have issued an emergency suspension of a cannabis testing lab’s license alleging the lab had submitted “incorrect and/or false” test results to its clients and the government.
