Pioneering Cannabis Safety & Compliance (2014-2024) PSI Labs was Michigan's first Safety Compliance Facility to hold both adult-use and medical licenses, setting the standard for cannabis testing, R&D, and quality assurance. Renowned for scientific accuracy and integrity, PSI Labs expanded into California in 2021 via the acquisition of pH Solutions. While PSI Labs closed its doors in early 2024, the company leaves a lasting legacy of advocacy for transparent, accurate data and consumer safety in the Michigan and California cannabis markets.
