Rep. Jonathan Singer, D-Longmont, listens to discussion on a bill he sponsored which would allow marijuana dispensaries to form financial co-operatives, at the Colorado Legislature, in Denver, Wednesday, May 7, 2014. Colorado lawmakers have approved the world's first financial system for the marijuana industry, a network of uninsured cooperatives designed to give pot businesses a way to access basic banking services. The plan, approved Wednesday, seeks to move the marijuana industry away from its cash-only roots. (AP Photo/Brennan Linsley) less
