Angell noted that in 2014 "more U.S. states are likely to vote on legalization, and leaders of other countries in Latin America are talking about the need for a new approach."
The Marijuana Policy Project, which was influential in passing the Colorado legalization measure, is currently working to legalize marijuana in 13 more states by 2017, either by voter initiative or legislative action.
Several Latin American leaders, including the president of Guatemala, have expressed an interest in legalizing marijuana. Legalization advocate Vicente Fox, the former president of Mexico, co-hosted a May press conference with former Microsoft executive Jamen Shively, who shared plans to launch an interstate cannabis brand. "What a difference it makes to have Jamen here sitting at my side instead of Chapo Guzman," Fox said, referring to the murderous cartel leader.
