SB 643 modifies Oklahoma's medical marijuana licensing rules by requiring all dispensary and grower license applicants to be Oklahoma residents, limiting non-resident ownership to 25% or less, and mandating that all managers, board members, and employees reside in the state. It affects new applicants for medical marijuana dispensary and commercial grower licenses, updating existing ownership and residency requirements under Sections 421 and 422 of Oklahoma law. The bill does not change patient access, sales rules, or tax structures but strengthens local ownership controls for these facilities. It amends statutory language to clarify these requirements and takes effect upon passage.
