Ridgefield residents have voted to ban cannabis businesses in town.  During a Special Town Meeting this week, residents voted 144 to 43 to ban marijuana sales.  Three public hearings were held on the matter.  The Board of Selectmen voted in April, 4 to 1, to prohibit cannabis business.  The Planning and Zoning Commission passed a one-year moratorium in September, but Ridgefield officials wanted residents to weigh in.  The state legislation allows municipalities the decision on whether to allow 11 types of businesses ranging from cultivators to retailers and transporters.  In municipalities where it's allowed through zoning, Cannabis sales are expected to begin at the end of this year.
