Nine cities in Colorado allow recreational marijuana sales, including the first and third largest cities by population (Denver and Aurora) and 23 cities prohibit or have moratoria on recreational sales. However, using the 2010 census data and this map, about 1.1 million citizens live in cities where recreational sales are allowed whereas about 1.4 million live in cities without recreational marijuana sales. A few smaller cities may not be included in the prohibited total. Population changes since 2010 likely cause some inaccuracy in these numbers.
Not everyone in Colorado, even in this heavily populated area, has bought in to Amendment 64, especially as we continue to see the negative effects.
