Is Medical Marijuana Legal in Hawaii?

Act 242 established Hawaii’s licensing system for medical marijuana dispensaries, and prohibiting counties from enacting zoning regulations that discriminate against licensed dispensaries and production centers. Democratic Gov. David Ige signed the act in 2015. The Medical Cannabis Dispensary Program, created by Act 241, was also established in 2015. The law paved the way for the establishment of dispensaries in Hawaii and also amended existing Hawaii marijuana laws governing the medical use of cannabis.
