The National Cannabis Industry Association (NCIA) is an American non-profit organization based in the District of Columbia, with an additional office in Denver, Colorado. NCIA is the largest cannabis trade association in the U.S. and the only organization representing state-sanctioned cannabis-related businesses at the federal level. Its mission is "to promote the growth of a responsible and legitimate cannabis industry and work for a favorable social, economic and legal environment for that industry in the United States." The organization was founded in late 2010 and has been described as the "first national trade group for the cannabis industry" in the United States.
