In 2000, medical marijuana was legalized but a dispensary system was not established. From 2000 to 2015, patients were allowed to grow medicinal marijuana for themselves or designate a caretaker to grow it for them. In 2015, a law was passed outlining a dispensary system. In 2017, the first medical marijuana dispensary opened and the first legal sale of medical marijuana was made.
