The leader of the organization that sponsored the voter-approved Mississippi medical marijuana initiative that was recently blocked in court says the program should be changed and improved by the state Legislature — but not by too much. Medical marijuana advocates were outraged last month when the state Supreme Court ruled that Mississippi’s initiative process is outdated and therefore the initiative is void. Mississippi Medical Marijuana Association executive director Ken Newburger said when Initiative 65 was written, he and others made some “short-sighted” missteps, such as tasking the state Department of Health with running the program on its own.
