Selectmen in Freetown are working with other local boards and officials to devise a fee structure for medical marijuana dispensaries. Selectmen chairman Paul Sadeck said two companies have contacted Freetown’s town administrator expressing an interest in opening such a dispensary. “This isn’t going to happen tomorrow. We’re still waiting on information from the state before things start happening,” Sadeck said. “But once it does happen, there are going to be fees incurred, like inspection costs, and we want to have those fees in place beforehand.” A ballot initiative approved in Massachusetts last fall allows state health officials to register up to 35 dispensaries in the first year, with at least one, but no more than five, dispensaries per county.
