Earlier this week, a recreational marijuana company, Core Empowerment, gained approval by Boston’s Zoning Board of Appeals, bringing it one step closer to opening in Jamaica Plain. The next step is for Core Empowerment to appear in front of the state’s Cannabis Control Commission (CCC) to get a license to open. Co-owner Tomas Gonzalez said no date has been set for a CCC meeting. Core has also signed a lease to go into a long-vacant basement level commercial space in Hyde Square. And for the most part there hasn’t been much reefer madness about a recreational marijuana company opening in Jamaica Plain.
