On Nov. 9, David Brown of the Texas Standard sat down with Gary J. Hale to discuss what legalization in Mexico could mean for America. Hale is a fellow in drug policy and Mexico studies at Rice University's Baker Institute for Public Policy. He also served as the chief of intelligence at the DEA's Houston Field division from 2000-2010.

Hale says Mexican legalization won't likely end America's War on Drugs because cartels will switch to importing heroin, cocaine and other illegal substances into the U.S. But legalization could force the international community to revise drug conventions and treaties that govern global cannabis laws.
