# National Cannabis Laboratory Council (NCLC)

> The National Cannabis Laboratory Council (NCLC) is a volunteer coalition of state-licensed cannabis laboratories, scientists, and medical- and science-focused ancillary operators formed in 2021 to promote science-based, national lab-testing standards for cannabis products. Rather than accept the patchwork of state-by-state testing rules, NCLC pools analytical data and pushes for harmonized test panels, sampling methods, and lab accreditation - the plumbing that would make interstate cannabis commerce possible and protect consumers. Originally organized in collaboration with law firm Perkins Coie, the council now runs its forum through the S3 Collective.
