DENVER (AP) -- Colorado's marijuana legalization measure has a new supporter.

The NAACP's Colorado-Wyoming-Montana Conference announced its endorsement Thursday. Group members say that marijuana laws disproportionately impact communities of color and low-income individuals.

Colorado is one of three states where voters this fall will consider legalizing marijuana for recreational use. Colorado's version would allow marijuana possession in small amounts by adults over 21 without the need for a doctor's recommendation. The measure would also allow commercial marijuana sales, with the product subject to a steep excise tax.
