Last week, the small town of Norwood, Colo., joined more than 100 other cities and towns in the state that have banned marijuana sales or imposed a moratorium, as the state implements a legalized recreational pot market. Norwood residents voted in favor of the November ballot initiative to legalize marijuana 150 to 94. But the City Council nonetheless voted not to let pot shops in — wary of being among the first to enter uncharted territory.
