The legalization and sale of marijuana in Colorado since 2014 has reduced the operations of Mexican drug cartels both along the southern U.S. border as well as inside this country, according to a report released Monday by a group specializing in legal matters.

The report, published by Lawyer Herald, uses recent statistics from several sources to conclude that the legal production, distribution and sale of recreational marijuana in Colorado is one of the factors that has caused the reduction in smuggling operations by Mexican drug cartels.

Legal marijuana in Colorado seems to have helped with resolving the problem of drugs in Mexico, says the report, citing the pro-marijuana Weed Blog, which says that over the past two years trafficking of the drug by Mexican cartels has dropped by "up to 70 percent."

An official report by the U.S. Drug Enforcement Administration in October 2015 confirmed the reduction, showing that in 2014 there had been a year-on-year 23 percent drop in border smuggling.

In addition, despite that, authorities have seized some 900 tons of illegal marijuana at the border.

The recreational use of pot was legalized in Colorado in November 2012 when a wide majority of voters approved Amendment 64.

Reports released last month by Carnegie-Mellon University and the University of Maryland show that the dropoff in activities of Mexican drug smugglers along the border is due to the creation in Colorado of a black market in a type of pot that is more potent that the Mexican variety, which is illegally distributed in other states.

In contrast, another analysis published recently by ABC News documents the presence in the state of large-scale drug traffickers who came there specifically to cultivate pot and send it to more lucrative markets, noting that nobody knows exactly how much marijuana is shipped out of Colorado. EFE
