ACT Lab

ACT Lab (formerly ACT Laboratories, Inc., rebranded July 2023) is a single, privately owned company operating cannabis and hemp testing labs and customer support teams in 7+ states, including Illinois, Michigan, New York, Ohio, Pennsylvania, Florida and Tennessee, with New Jersey in development. Services include cannabinoid and contaminant compliance testing, environmental monitoring, a plant pathogens program, NIR technology, R&D support and kratom testing, with quality systems the company says mirror pharmaceutical-industry standards.

Headquartered at 617 E Hazel Street, Lansing, MI, ACT Lab grew through organic multi-state expansion and acquisition, including its May 2023 purchase of Florida's Green Scientific Lab Holdings. In November 2025 it moved its Ohio operations into a new Columbus laboratory. It holds ISO/IEC 17025:2017 accreditation.
