Wayland Patch 12/5/12: Planning Board Considers Zoning Bylaw for Marijuana Dispensaries. Wayland Planning Board members Tuesday night agreed to hold a public hearing in early January in order to set the wheels in motion on potentially amending the town’s zoning bylaw to address marijuana treatment centers. Town Planner Sarkis Sarkisian told the board that several towns in the Commonwealth have already taken steps to regulate where and whether medical marijuana dispensaries can operate in their towns once Ballot Question 3 goes into effect on Jan. 1, 2013.
