Mississippi Gov. Tate Reeves said Wednesday he is working with legislative leaders on details about how the state will pay for a proposed medical marijuana program.

The Republican governor said he will call lawmakers to the Capitol for a special session “sooner rather than later,” but he has not decided when.

House and Senate leaders want to enact a medical marijuana program to replace an initiative voters approved in November. State Supreme Court justices overturned the initiative in May when they ruled that Mississippi’s initiative process is outdated and unworkable.

Reeves said he has had productive talks this week with Lt. Gov. Delbert Hosemann and House Speaker Philip Gunn, who are also Republicans.
