Can Cities Block Legal Pot?

Washington State voters overwhelmingly approved a legal cannabis industry last November, yet many cities and counties have since enacted moratoriums on pot businesses. City councils in Olympia, Kent, Sammamish, Puyallup, University Place, Sunnyside, Pacific, East Wenatchee, Mill Creek, Longview, and Millwood have enacted moratoriums, as have the councils in Clark, Pierce, and Yakima Counties.
