In November of last year, Federal drug agents raided multiple drug dispensaries and legal grow operations. This came even after the state legalized the use of marijuana for recreational purposes. Agents suspected that cartels were using the front of legitimate businesses to make money illegally.
The agents told the local news that the raids were part of an investigation into alleged Columbian cartel members operating in Colorado. A major issue is that while Marijuana is legal in Colorado, it is still illegal in the vast majority of other states. This presents Cartels with an excellent opportunity to operate inside the United States with protection from police and then send their crops to states where the drug remains illegal. Any cartel activity in Colorado can be a problem for law enforcement in other states.
