U.S. policy on drug trafficking is not consistent with the need to put an end and actively repress the consumption of drugs. The solution is not based on the destruction of a native plant, coca, in the continent, but on an active fight against the Colombian drug mafia, which has created a great money and crime empire in Colombia with powerful ramifications outside its borders.
The columbia drug mafia is considered responsible for the cocaine problem in the U.S.
The text mentions that the columbian drug mafia is mentioned as being what needs to be dealt with so solve the cocaine problem, I think this confused the system as the article mentions the source plant coca but never the actual drug name.
