Canada is following the lead of Uruguay in allowing a nationwide, legal marijuana market, although each Canadian province is working up its own rules for pot sales. The federal government and the provinces also still need to publish regulations that will govern the cannabis trade. (Darryl Dyck/The Canadian Press via AP, File)
