An adult-use marijuana dispensary planned for the Westside of Watertown entered into a Host Community with the Town after the Town Council approved the agreement on Tuesday night. Buds Goods & Provisions is applying to open a recreational marijuana dispensary in the new development at 330-350 Pleasant St. The company now must apply for a license from the Massachusetts Cannabis Control Commission (CCC) before it can apply to the Watertown Zoning Board for a special permit. They can open when both are approved. The ballot measure that legalized adult-use marijuana prohibits communities from banning them, but allows them to limit the number to 10 percent of the number of liquor licenses.
