A Town Council subcommittee narrowed down the applications for two marijuana dispensaries in town to operators seeking to open in locations in Watertown Square and on Pleasant Street. While the ballot question that legalized recreational marijuana dispensaries in Massachusetts prevents communities from banning pot from being sold, communities can limit the number of facilities. The Town Council has limited the number to three in Watertown. One dispensary has been approved to open at 23 Elm Street in the East End, and Town officials accepted applications for the other two dispensaries in town. Thursday evening, the Council’s Economic Development and Planning Committee reviewed the four applications, ultimately asked two to start the approval process: one at 48 North Beacon St.
