Oklahoma City — A pro-marijuana advocacy group has accused Board of Health members of holding secret meetings in violation of state law before making last-minute changes to the rules for medical pot.

The lawsuit, filed in Oklahoma County by Green the Vote, was one of two against the Oklahoma State Department of Health related to medical marijuana as of Friday afternoon. It also named Gov. Mary Fallin and five Board of Health members as defendants.

Michael McNutt, a spokesman for the governor, said she and her staff are reviewing the lawsuit.

The board approved rules Tuesday creating a framework for medical marijuana following passage of State Question 788 last month. During the meeting, board member Chuck Skillings introduced two amendments to ban the sale of smokable forms of marijuana, and to require dispensaries to hire a pharmacist.
