To impose a licensure mandate and authorize a comprehensive regulatory regime for medical marijuana growers, transporters, dispensaries and more, with civil and criminal penalties for violations. Also, to impose a 3 percent tax on retail sales. The provisions of the state's voter-authorized medical marijuana law, Initiated Law 1 of 2008, were ambiguous on dispensaries, and in 2013 the state Supreme Court declared the law does not authorize them. The bill would authorize them, but let local governments choose to ban them.
