The Oklahoma Medical Marijuana Authority said it is shutting down a local cannabis testing lab.
According to the agency, a routine compliance inspection led to OMMA inspectors identifying a concern at Greenleaf Labs that requires further scrutiny and analysis.
The OMMA did not share many specifics surrounding the reason for the shutdown. But it did warn businesses with products that were tested by Greenleaf Labs for total yeast and mold between April 2023 and July 31, 2025, that those products may be contaminated.
"OMMA is working with Greenleaf Labs to identify the specific products that were improperly tested and will release that information as soon as we have completed a thorough analysis," the agency said in a statement. "Due to the immediate risk to public health and safety, Greenleaf Labs’ OMMA license was summarily suspended on an emergency basis."
