The city’s elected officials are still sorting out how to regulate medical marijuana dispensaries nearly a year after they set a rule blocking new pot clubs. At Tuesday night’s City Council meeting, council members added another year to the existing ban on new medical pot dispensaries. However, Michelle Heppner, the city staffer who is working on ideas for regulation, said Wednesday that she would like to have an ordinance ready before the end of the year. Heppner, a special projects manager, said the time frame for setting up a medical pot ordinance would depend on the City Council’s decision-making process. The city currently has 39 medical pot clubs, Heppner said. Speakers in suppor
