Major Cannabis Retailer Ends Relationship with Arizona Testing Lab Over Quality Issues

Story Cannabis, a multi-state cannabis operator, has discontinued acceptance of products tested by an Arizona laboratory at its 11 Arizona retail locations due to repeated testing failures and quality control problems. The decision reflects growing industry standards requiring reliable cannabinoid analysis and contaminant screening to ensure product safety and accurate potency labeling for consumers. This action highlights the critical importance of third-party laboratory certification in the cannabis supply chain, particularly for medical patients who depend on accurate dosing and purity verification. Testing lab failures can compromise patient safety and undermine trust in regulated cannabis markets. The incident underscores ongoing regulatory challenges in establishing consistent quality assurance protocols across state-licensed cannabis operations.
