Editor's Note: This week's Security Weekly is a condensed version of our annual Mexico drug cartel report, in which we assess the most significant developments of 2014 and provide a forecast for 2015. The report is a product of the coverage we maintain through our Mexico Security Memo, quarterly updates and other analyses that we produce throughout the year as part of the Mexico Security Monitor service.

Under the Guadalajara cartel and its contemporaries, such as the Gulf cartel, led by Juan Garcia Abrego, a relatively small number of crime bosses controlled Mexico's terrestrial illicit supply chains.
