PSI Labs operated as a cannabis safety, testing, R&D, and quality-assurance facility based in Ann Arbor, Michigan. It was the state's first facility to hold both adult-use and medical licenses, establishing standards for cannabis testing and compliance. In 2021, the company expanded to California through the acquisition of pH Solutions. The organization was known for its emphasis on scientific accuracy and data integrity and advocated for transparent consumer safety in Michigan and California markets. It closed in early 2024, leaving a legacy as a founding member of the Leafly Certified Labs Program.
