Mexican drug cartels adapting to legalisation of marijuana in U.S.

The growing legalisation of cannabis in the United States is forcing Mexico’s drug cartels to rethink their illicit business model. A total of 23 U.S. states have legalised the drug for medical use, and opinion polls show that a slim majority of Americans favour legalisation. Javier Oliva, a security expert at the National Autonomous University of Mexico, said the number of opium poppy fields has surged by 300% in the last five years in Mexico’s southwestern state of Guerrero.

The criminals have obviously seen an improvement in [heroin] cultivation and they also pay attention to the demand factor.

Poppy fields outnumber marijuana plantations by three to one, according to Adolfo Dominguez, a military commander in Durango. And heroin consumption in the U.S. has surged due to tighter controls of prescription opioid drugs, said Alejandro Mohar, a member of the International Narcotics Control Board. Speaking at a presentation of a report by the UN’s International Narcotics Control Board, a United Nations agency, Oliva said drug cartels would also likely “increase their exports to Europe”.
