The Board of Selectmen on Monday is expected to consider amending its proposed bylaw restricting the location of medical marijuana dispensaries in town. The Planning Board last Monday voted to recommend that the April 23 special Town Meeting not approve the bylaw. The bylaw would restrict medical marijuana dispensaries to the town’s adult use overlay district and bar them from locating within 1,500 feet of a residential district, a school or child care facility, another medical marijuana treatment center, or an alcohol-pouring establishment. Town Administrator Edwin Thorne said that to meet the Planning Board’s objections, he expects selectmen to consider such changes as reducing the distance restriction to 500 feet, and revising language regarding the purpose of the bylaw. He said selectmen may also place a separate article on the warrant calling for a moratorium on medical marijuana dispensaries if Town Meeting does not approve the bylaw.
