State questions

State questions are ballot propositions to proposed either a legislative measure or an amendment to the Oklahoma Constitution. State questions are filed with the Oklahoma Secretary of State by either order of the legislature (termed a "legislative referendum") or directly by the people of Oklahoma (termed an "initiative petition"). The secretary of state assigns a number to the state question and notifies the State Election Board of the propositions submission. The governor, by executive proclamation, sets the election date for submission of the state questions to the people.

State Question 788

Oklahoma State Question 788 was an initiative petition which sought to legalize the licensed use, sale, and growth of marijuana in Oklahoma for medical purposes.
