On May 28, 2013, Governor Hickenlooper signed three bills into law that address the implementation of Amendment 64, including requirements for the State Licensing Authority (“SLA”) to adopt rules governing retail marijuana establishments. In order to comply with those requirements and those found in Amendment 64, the SLA adopted emergency rules governing retail marijuana in the state of Colorado on July 1, 2013. The emergency rules were then refined through a permanent rulemaking process during which the SLA hosted over forty hours of working groups meetings, reviewed nearly 300 written comments and held two days of formal hearings. After working extensively with stakeholders and reviewing all public input, the SLA adopted the permanent rules for retail marijuana and revised rules for medical marijuana on September 9, 2013.
