Story highlights. Colorado began allowing the sale of recreational marijuana on January 1 to anyone age 21 or older. Residents can now buy marijuana like alcohol -- except the cannabis purchase is limited to an ounce, which is substantial enough to cost about $200 or more.
Itâs likely that this boost in pot sales is not just coming from Colorado residents. In 2014, 71.3 million visitors spent $18.6bn in Colorado, both record highs that coincided with the first year of marijuana legalization. Figures for 2015 tourism havenât been released yet.
