The Brookfield Zoning Commission has approved regulations for medical marijuana dispensaries.  In the unanimous decision, the Zoners agreed to limiting such a facility to the industrial district, and only up to 4,00 square feet.  There are no applications for a dispensary in Brookfield, but the state does plan to issue nearly a dozen new licenses. A moratorium in Brookfield had previously expired.    Even if the state law changes, the Brookfield zoning law would only allow a dispensary in town to sell medical marijuana to people with prescriptions.
