A new report has revealed that since the voters in Colorado voted by a wide majority to approve Amendment 64, which legalized the production and sales of marijuana in 2012, the measure has directly led to the decrease of the operational capabilities of Mexican drug cartels on both sides of the border.

Marijuana has long been the number one revenue generator of the drug syndicates in Mexico. However, a report by Lawyer Herald, which cites recent statistics from several sources to conclude that legalization in the state is one of the mitigating factors that has led to the reduction in drug trafficking operation by the drug cartels on Mexico.

“The legalization of  marijuana in the state of Colorado appears to have helped with resolving the problem of drugs in Mexico, says the report, citing the pro-marijuana Weed Blog, which reveals that smuggling of cannabis by from Mexico has witnessed a 70 percent decrease over the past two years.”

The U.S. Drug Enforcement Administration confirms the report’s findings. An official DEA report released in October 2015 shows how border smuggling of marijuana in 2014 showed a 23 percent drop.

Authorities still have confiscated around 900 tons of illegal marijuana at the border despite the impact of legalization.

Additional reports published last month by Carnegie-Mellon University and the University of Maryland shows how the creation of a black market of weed cultivated in Colorado, which has led to the smuggling and illegal distribution of potent strains of marijuana throughout other states has hurt the Mexican drug smuggling operations along the border

However, another analysis recently published by ABC News indicated the presence of large-scale drug traffickers in the state of Colorado, who specifically came there to cultivate and smuggle the potent marijuana to bigger, more lucrative markets, noting, authorities do not know how much marijuana is shipped out of Colorado.
